Description

Foreliggende oppfinnelse omhandler bremsevæsker for motorkjøretøyer, som har forbedret korrosjonsbeskyttelse. The present invention relates to brake fluids for motor vehicles, which have improved corrosion protection.

Bremsevæsker for motorkjøretøyer utsettes for svært høye krav med hensyn til deres kjemiske og fysiske egenskaper. I samsvar med de eksisterende standarder og spesifikasjoner for bremsevæsker fra the US Department of Transportation i Federal Motor Vehicle Safety Standard FMVSS-Nr. 116 og SAE J 1704 standarden publisert av the Society of Automotive Engineers, skulle moderne bremsevæsker på den ene siden ha høye tørre kokepunkter (likevekts reflukskokepunkter "ERBP") og høye våte kokepunkter ("våte ERBP"), men skulle på den andre siden også ha en viskositet som bare endres svakt innen et bredt temperaturområde. Brake fluids for motor vehicles are subjected to very high demands with regard to their chemical and physical properties. In accordance with the existing standards and specifications for brake fluids from the US Department of Transportation in the Federal Motor Vehicle Safety Standard FMVSS-Nr. 116 and the SAE J 1704 standard published by the Society of Automotive Engineers, modern brake fluids should on the one hand have high dry boiling points (equilibrium reflux boiling points "ERBP") and high wet boiling points ("wet ERBP"), but should on the other hand also have a viscosity that changes only slightly within a wide temperature range.

I tillegg, er det mer krevende krav fra bilindustrien til forbedret korrosjonsbeskyttelse i tilfelle metaller og jernfrie metaller. Korrosjonsinhibitorer i bremsevæsker har oppgaven med å forhindre ødeleggelse av metalliske materialer forårsaket av korrosjon. In addition, there are more demanding requirements from the automotive industry for improved corrosion protection in the case of metals and non-ferrous metals. Corrosion inhibitors in brake fluids have the task of preventing the destruction of metallic materials caused by corrosion.

Anvendelsen av 1H-1,2,3-triazoler, slik som 1H-1,2,3-benzotriazol eller 1H-1,2,3-tolutriazol, som korrosjonsinhibitorer i hydrauliske væsker eller bremsevæsker har lenge vært kjent, for eksempel fra EP-A 028 789 (1) og EP-A454 110(2). The use of 1H-1,2,3-triazoles, such as 1H-1,2,3-benzotriazole or 1H-1,2,3-tolutriazole, as corrosion inhibitors in hydraulic fluids or brake fluids has long been known, for example from EP -A 028 789 (1) and EP-A 454 110 (2).

WO 00/46325 (3) anbefaler hydrauliske væsker som omfatter en kombinasjon av 1 H-1,2,3-benzotriazol eller derivater derav, slik som 1 H-1,2,3-tolutriazol, og 1 H-1,2,4-triazol eller derivater derav i et vektforhold på fra 1:4 til 4:1 som korrosjonsinhibitorsystem. For sammenlignende formål, indikerer Tabeller 1 til 4 i (3) også hydrauliske væsker som omfatter 1 H-1,2,4-triazol alene i konsen-trasjoner på 0,15 vekt-%; imidlertid, er dens korrosjonsinhiberende virkning akseptabel kun i tilfellet med kobber. WO 00/46325 (3) recommends hydraulic fluids comprising a combination of 1 H-1,2,3-benzotriazole or derivatives thereof, such as 1 H-1,2,3-tolutriazole, and 1 H-1,2, 4-triazole or derivatives thereof in a weight ratio of from 1:4 to 4:1 as a corrosion inhibitor system. For comparative purposes, Tables 1 to 4 in (3) also indicate hydraulic fluids comprising 1H-1,2,4-triazole alone in concentrations of 0.15% by weight; however, its corrosion inhibiting action is acceptable only in the case of copper.

Bremsevæsker for motorkjøretøyer som er kjent fra tidligere teknikk er, imidlertid, fremdeles utilfredsstillende med hensyn til deres egenskaper og spesielt deres korrosjonsbeskyttelse. Det var derfor et formål med foreliggende oppfinnelse å tilveiebringe bremsevæsker som, spesielt, tilfredsstiller oven-nevnte krav til forbedret korrosjonsbeskyttelse i tilfellet metaller og jernfrie metaller. Brake fluids for motor vehicles known from the prior art are, however, still unsatisfactory with regard to their properties and especially their corrosion protection. It was therefore an object of the present invention to provide brake fluids which, in particular, satisfy the above-mentioned requirements for improved corrosion protection in the case of metals and non-ferrous metals.

Den foreliggende oppfinnelsen tilveiebringer følgelig en bremsevæske for motorkjøretøyer som har forbedret korrosjonsbeskyttelse, som omfatter (a) fra 0,005 til 0,125 vekt-% 1 H-1,2,4-triazol, og (b) fra 0 til 10 vekt-% av én eller flere ytterligere korrosjonsinhibitorer, hvor, ved samtidig anvendelse av 1 H-1,2,3-benzotriazol og/eller 1 H-1,2,3-tolutriazol og/eller derivater derav, vektforholdet mellom 1 H-1,2,4-triazol og nevnte 1H-1,2,3-triazoler må være større enn 4:1, og videre fra 0,1 til 97 vekt-% av én eller flere polyglykoletere og/eller borsyreestere derav. Motorkjøretøybremsevæskene ifølge oppfinnelsen omfatter foretrukket fra 0,005 til 0,10 vekt-%, foretrukket fra 0,005 til 0,08 vekt-%, spesielt fra 0,005 til 0,06 vekt-%, av komponent (a). Accordingly, the present invention provides a motor vehicle brake fluid having improved corrosion protection comprising (a) from 0.005 to 0.125% by weight of 1H-1,2,4-triazole, and (b) from 0 to 10% by weight of one or several additional corrosion inhibitors, where, with the simultaneous use of 1 H-1,2,3-benzotriazole and/or 1 H-1,2,3-tolutriazole and/or derivatives thereof, the weight ratio between 1 H-1,2,4 -triazole and said 1H-1,2,3-triazoles must be greater than 4:1, and further from 0.1 to 97% by weight of one or more polyglycol ethers and/or boric acid esters thereof. The motor vehicle brake fluids according to the invention preferably comprise from 0.005 to 0.10% by weight, preferably from 0.005 to 0.08% by weight, especially from 0.005 to 0.06% by weight, of component (a).

I en foretrukket utførelse, omfatter motorkjøretøybremsevæskene ifølge oppfinnelsen komponent (a) som den eneste triazol-baserte korrosjonsinhibitor. Dette er tenkt å bety at triazoler, slik som 1H-1,2,3-benzotriazol, 1H-1,2,3-tolutriazol eller hydrogenert 1 H-1,2,3-tolutriazol, er utelukket her, men uorganiske og/eller organiske korrosjonsinhibitorer som har en forskjellig struktur kan likevel være til stede. In a preferred embodiment, the motor vehicle brake fluids according to the invention comprise component (a) as the only triazole-based corrosion inhibitor. This is intended to mean that triazoles, such as 1H-1,2,3-benzotriazole, 1H-1,2,3-tolutriazole or hydrogenated 1H-1,2,3-tolutriazole, are excluded here, but inorganic and/ or organic corrosion inhibitors that have a different structure may still be present.

Passende ytterligere korrosjonsinhibitorer (b) her er, spesielt, alkalimetallsalter av fosforsyre og fosforholdig syre, fettsyrer, slik som kapryl-, laurin-, palmitin-, stearin- eller oleinsyre og alkalimetallsalter derav, estere av fosforsyre og fosforholdig syre, slik som etylfosfat, dimetylfosfat, isopropylfosfat, diisopropyl-fosfat, butylfosfitt eller dimetylfosfitt, eventuelt etoksylerte mono- og dialkyl-aminer og salter derav med mineralsyrer og fettsyrer, for eksempel butylamin, heksylamin, oktylamin, isononylamin, oleylamin, dipropylamin, diisopropylamin eller dibutylamin, eventuelt etoksylerte alkanolaminer, for eksempel mono-, di-eller trietanolamin, N,N'-di-n-butylaminoetanol eller 1,1'-iminodipropan-2-ol, cykloheksylamin, benzimidazol og hydrogenert tolutriazol, og nitroaromatisk forbindelser, for eksempel 3-nitrobenzaldehyd. Suitable further corrosion inhibitors (b) here are, in particular, alkali metal salts of phosphoric acid and phosphoric acid, fatty acids, such as caprylic, lauric, palmitic, stearic or oleic acid and alkali metal salts thereof, esters of phosphoric acid and phosphoric acid, such as ethyl phosphate, dimethyl phosphate, isopropyl phosphate, diisopropyl phosphate, butyl phosphite or dimethyl phosphite, optionally ethoxylated mono- and dialkyl amines and their salts with mineral acids and fatty acids, for example butylamine, hexylamine, octylamine, isonylamine, oleylamine, dipropylamine, diisopropylamine or dibutylamine, optionally ethoxylated alkanolamines, for example mono-, di- or triethanolamine, N,N'-di-n-butylaminoethanol or 1,1'-iminodipropan-2-ol, cyclohexylamine, benzimidazole and hydrogenated tolutriazole, and nitroaromatic compounds, for example 3-nitrobenzaldehyde.

Nevnte korrosjonsinhibitorer (b) er foretrukket til stede i motorkjøretøy-bremsevæskene ifølge oppfinnelsen i mengder fra 0,001 til 10 vekt-%, spesielt fra 0,001 til 5 vekt-%. Said corrosion inhibitors (b) are preferably present in the motor vehicle brake fluids according to the invention in amounts from 0.001 to 10% by weight, especially from 0.001 to 5% by weight.

I en spesielt foretrukket utførelse, omfatter motorkjøretøybremsevæskene ifølge oppfinnelsen, ut over 1 H-1,2,4-triazol (a), som ytterligere korrosjonsinhibitorer (b) fra 0,001 til 0,5 vekt-%, av én eller flere forbindelser fra gruppen som består av benzimidazol, hydrogenert 1 H-1,2,3-tolutriazol, purin, adenin, 6-klorpurin, 2,6-diklorpurin, 6-metoksypurin, 1 H-1,2,3-triazolo(4,5-d)pyridin, 6-histaminopurin og 6-furfurylaminopurin og, eventuelt, ytterligere korrosjonsinhibitorer andre enn (a). Nevnte purinderivater er beskrevet i Tysk patentsøknad P 100 26 010.1 som jernfrie metallkorrosjonsinhibitorer for hydrauliske væsker eller bremsevæsker. In a particularly preferred embodiment, the motor vehicle brake fluids according to the invention comprise, in addition to 1 H-1,2,4-triazole (a), as additional corrosion inhibitors (b) from 0.001 to 0.5% by weight, of one or more compounds from the group consisting of benzimidazole, hydrogenated 1 H-1,2,3-tolutriazole, purine, adenine, 6-chloropurine, 2,6-dichloropurine, 6-methoxypurine, 1 H-1,2,3-triazolo(4,5- d) pyridine, 6-histaminopurine and 6-furfurylaminopurine and, optionally, additional corrosion inhibitors other than (a). Said purine derivatives are described in German patent application P 100 26 010.1 as iron-free metal corrosion inhibitors for hydraulic fluids or brake fluids.

Alle vektprosent data gitt over og under relateres i hvert tilfelle til totalmengden av bremsevæsken, så fremt ikke annet er angitt. Summen av alle komponenter listet over og under for bremsevæskene ifølge oppfinnelsen summeres i hvert tilfelle opp til 100 vekt-%. All weight percentage data given above and below relate in each case to the total amount of brake fluid, unless otherwise stated. The sum of all components listed above and below for the brake fluids according to the invention is added up to 100% by weight in each case.

Foreliggende oppfinnelse omhandler bremsevæsker for motorkjøretøyer som omfatter, som korrosjonsinhibitorer, nevnte komponenter (a) og, hvis ønsket, (b). The present invention relates to brake fluids for motor vehicles which comprise, as corrosion inhibitors, said components (a) and, if desired, (b).

I en foretrukket utførelse, omfatter motorkjøretøybremsevæskene ifølge oppfinnelsen videre, i tillegg til komponentene (a) og, eventuelt, (b), fra 0,1 til 97 vekt-%, spesielt fra 30 til 97 vekt-%, fremfor alt fra 50 til 97 vekt-%, av én eller flere polyglykoletere og/eller borater derav. In a preferred embodiment, the motor vehicle brake fluids according to the invention further comprise, in addition to components (a) and, optionally, (b), from 0.1 to 97% by weight, in particular from 30 to 97% by weight, above all from 50 to 97% by weight, of one or more polyglycol ethers and/or borates thereof.

Passende polyglykoletere her er, spesielt, etylenglykol monoalkyletere som har opp til 6 etylenoksidenheter og som har opp til 4 karbonatomer i alkylradikalen, for eksempel dietylenglykol monometyleter, trietylenglykol monometyleter, trietylenglykol monobutyleter eller tetraetylenglykol monometyleter. Passende er også etylenglykol dialkyletere og propylenglykol dialkyletere som har opp til 6 alkylenoksidenheter og som har opp til 4 karbonatomer i hver av alkyl-radikalene, for eksempel trietylenglykol dimetyleter, tetraetylenglykol dimetyleter, dietylenglykol di-tert-butyleter, dietylenglykol dibutyleter, dietylenglykol di-tert-butyleter eller dipropylenglykol dimetyleter. Suitable polyglycol ethers here are, in particular, ethylene glycol monoalkyl ethers which have up to 6 ethylene oxide units and which have up to 4 carbon atoms in the alkyl radical, for example diethylene glycol monomethyl ether, triethylene glycol monomethyl ether, triethylene glycol monobutyl ether or tetraethylene glycol monomethyl ether. Also suitable are ethylene glycol dialkyl ethers and propylene glycol dialkyl ethers which have up to 6 alkylene oxide units and which have up to 4 carbon atoms in each of the alkyl radicals, for example triethylene glycol dimethyl ether, tetraethylene glycol dimethyl ether, diethylene glycol di-tert-butyl ether, diethylene glycol dibutyl ether, diethylene glycol di-tert -butyl ether or dipropylene glycol dimethyl ether.

Passende borsyreestere av nevnte eller andre polyglykoletere er beskrevet, spesielt, i patentskriftene EP-B 013 925 (cykliske bisborsyreestere), DE-C 28 04 535 (nitrogen-holdige borsyreestere), DE-A 24 38 038 (borsyre alkylenglykol monoalkyleter estere) og DE-B 17 68 933 (borsyre trisalkoksyalkyl estere). Suitable boronic acid esters of the aforementioned or other polyglycol ethers are described, in particular, in the patent documents EP-B 013 925 (cyclic bisboric acid esters), DE-C 28 04 535 (nitrogen-containing boronic acid esters), DE-A 24 38 038 (boric acid alkylene glycol monoalkyl ether esters) and DE-B 17 68 933 (boric acid trisalkoxyalkyl esters).

I stedet for nevnte polyglykoletere og/eller borsyreestere derav, kan motor-kjøretøybremsevæskene ifølge oppfinnelsen også omfatte, som hoved-komponent, slike basert på karboksylsyreestere, mineral oljer eller silikonoljer. Instead of said polyglycol ethers and/or boric acid esters thereof, the motor vehicle brake fluids according to the invention can also comprise, as main component, those based on carboxylic acid esters, mineral oils or silicone oils.

I en ytterligere foretrukket utførelse, omfatter motorkjøretøybremsevæskene ifølge oppfinnelsen videre, ut over komponenter (a) og, hvis ønsket, (b), fra 0,1 til 50 vekt-%, spesielt fra 1 til 40 vekt-%, spesielt fra 5 til 30 vekt-%, av én eller flere polyglykoler. In a further preferred embodiment, the motor vehicle brake fluids according to the invention further comprise, in addition to components (a) and, if desired, (b), from 0.1 to 50% by weight, in particular from 1 to 40% by weight, in particular from 5 to 30% by weight of one or more polyglycols.

Passende polyglykoler her er, spesielt, relativt høytkokende produkter av reaksjonen av etylenoksid og/eller propylenoksid og/eller butylenoksid med vann eller dioler, spesielt tilsvarende produkter av blandinger av etylenoksid og propylenoksid med vann. Antallet alkylenoksidenheter i polyglykoler av denne typen er vanligvis fra 2 til 10. Suitable polyglycols here are, in particular, relatively high-boiling products of the reaction of ethylene oxide and/or propylene oxide and/or butylene oxide with water or diols, especially corresponding products of mixtures of ethylene oxide and propylene oxide with water. The number of alkylene oxide units in polyglycols of this type is usually from 2 to 10.

Virkningen av disse høytkokende polyglykoler er den til et smøremiddel, som grunnleggende kan tilskrives en forbedring i temperatur/viskositets opptreden. Polyglykolene gir polyglykoleterne med lav viskositet tilstrekkelig viskositet ved høye temperaturer og sikrer derfor tilstrekkelig smøring. Tilstrekkelig smøring er nødvendig i komponentene i motorkjøretøyets bremsesystem siden gummi eller elastomerer må skli på metall med svært lav slitasje i disse systemene. Nærværet av nevnte lille mengde 1 H-1,2,4-triazol sikrer på en utmerket måte, at motorkjøretøybremsevæskene ifølge oppfinnelsen møter kravet nevnt i innledningen og at, spesielt, en korrosjonsopptreden som generelt er god sammenlignet med tidligere teknikk, dvs. forbedret korrosjonsbeskyttelse i tilfelle metaller, slik som jern, stål, blikk, støpejern (grått jern), bly, tinn, krom, sink, aluminium, magnesium og legeringer derav, og i tilfelle loddemetaller, for eksempel loddetinn, og i tilfelle jernfrie metaller, slik som kobber og legeringer derav, for eksempel messing, bevirkes. Ytterligere fordeler med motorkjøretøybremsevæskene ifølge oppfinnelsen er deres gunstige lav-temperatur viskositet, god vann kompatibilitet, en mild pH, god lav-temperatur, høy-temperatur og oksidasjonsstabilitet og god kjemisk stabilitet, en gunstig opptreden (dvs. god kompatibilitet) med materialer slik som gummier, plaster, limfuger, fiber-, elastomer- og gummiforseglinger og lignende materialer, så vel som god smørende opptreden. The effect of these high-boiling polyglycols is that of a lubricant, which is basically attributable to an improvement in temperature/viscosity behavior. The polyglycols give the polyglycol ethers with low viscosity sufficient viscosity at high temperatures and therefore ensure sufficient lubrication. Adequate lubrication is required in the components of the motor vehicle braking system since rubber or elastomers must slide on metal with very low wear in these systems. The presence of said small amount of 1 H-1,2,4-triazole ensures in an excellent way that the motor vehicle brake fluids according to the invention meet the requirement mentioned in the introduction and that, in particular, a corrosion behavior which is generally good compared to the prior art, i.e. improved corrosion protection in the case of metals, such as iron, steel, tin, cast iron (gray iron), lead, tin, chromium, zinc, aluminium, magnesium and their alloys, and in the case of solders, such as solder, and in the case of non-ferrous metals, such as copper and its alloys, for example brass, are wrought. Further advantages of the motor vehicle brake fluids according to the invention are their favorable low-temperature viscosity, good water compatibility, a mild pH, good low-temperature, high-temperature and oxidation stability and good chemical stability, a favorable behavior (ie good compatibility) with materials such as rubbers, plasters, adhesive joints, fiber, elastomer and rubber seals and similar materials, as well as good lubricating behavior.

Ikke minst, er anvendelsen av kun en liten mengde 1 H-1,2,4-triazol i motor-kjøretøybremsevæskene ifølge oppfinnelsen fordelaktig både økonomisk og økologisk. Not least, the use of only a small amount of 1H-1,2,4-triazole in the motor vehicle brake fluids according to the invention is advantageous both economically and ecologically.

Bremsevæsker BF 1a og BF 2a ifølge oppfinnelsen avviker fra BF 1 og BF 2 kun i det at de 0,05 vekt-% 1 H-1,2,3-tolutriazol har blitt erstattet med den samme mengde 1 H-1,2,4-triazol; bremsevæske BF 1b omfatter 0,04 vekt-% 1 H-1,2,4-triazol og 0,01 vekt-% adenin i stedet for 0,05 vekt-% 1 H-1,2,3-tolutriazol; bremsevæske BF 1c ifølge oppfinnelsen omfatter 0,07 vekt-% 1 H-1,2,4-triazol (men kun 54,98 vekt-% trietylenglykol monometyleter borat) i stedet for 0,05 vekt-% 1 H-1,2,3-tolutriazol. Brake fluids BF 1a and BF 2a according to the invention differ from BF 1 and BF 2 only in that the 0.05% by weight of 1H-1,2,3-tolutriazole has been replaced with the same amount of 1H-1,2, 4-triazole; brake fluid BF 1b comprises 0.04% by weight 1H-1,2,4-triazole and 0.01% by weight adenine instead of 0.05% by weight 1H-1,2,3-tolutriazole; brake fluid BF 1c according to the invention comprises 0.07% by weight 1H-1,2,4-triazole (but only 54.98% by weight triethylene glycol monomethyl ether borate) instead of 0.05% by weight 1H-1,2 ,3-tolutriazole.

Anvendelsesstudiene ble utført i samsvar med PSA Peugeot-Citroén D 53 5387 kobber-korrosjonstesten i 2000 versjonen. I denne testen, blir først en kobberplate som tidligere er renset i aceton, med et totalt overflateareal på 1000 cm<2> (dimensjoner: 71,4 cm x 7 cm x 0,05 cm) kveilet opp i form av en rund sylinder på en slik måte at metalloverflaten på innsiden ikke er i kontakt med seg selv. Kobberplaten plasseres i en blanding av 294 ml bremsevæske som inneholder 6 ml destillert vann og varmes opp ved 100°C i 100 timer; 10 liter per time med luft, som tidligere hadde blitt ført gjennom destillert vann kjølt til 2°C føres gjennom væsken. Etter testen, blir utseendet til en utrullede kobberplaten og utseendet til væsken visuelt bedømt, og kobberinnholdet i væsken bestem-mes. The application studies were carried out in accordance with the PSA Peugeot-Citroén D 53 5387 copper corrosion test in the 2000 version. In this test, first a copper plate previously cleaned in acetone, with a total surface area of 1000 cm<2> (dimensions: 71.4 cm x 7 cm x 0.05 cm) is coiled up in the form of a round cylinder on such a way that the metal surface on the inside is not in contact with itself. The copper plate is placed in a mixture of 294 ml of brake fluid containing 6 ml of distilled water and heated at 100°C for 100 hours; 10 liters per hour of air, which had previously been passed through distilled water cooled to 2°C, is passed through the liquid. After the test, the appearance of an unrolled copper sheet and the appearance of the liquid are visually judged, and the copper content of the liquid is determined.

Resultatene fra testen beskrevet er vist i Tabell 1 under. The results from the test described are shown in Table 1 below.

Det kan sees at formuleringene ifølge oppfinnelsen, i motsetning til kon-vensjonelle bremsevæsker, slik som BF 1 og BF 2, ikke bare gir svært god kobber korrosjonsbeskyttelse med et lavt Cu innhold i testvæsken, men i tillegg også gir en beleggfri metalloverflate og ingen sedimentdannelse i bremsevæsken. It can be seen that the formulations according to the invention, in contrast to conventional brake fluids, such as BF 1 and BF 2, not only provide very good copper corrosion protection with a low Cu content in the test fluid, but also provide a coating-free metal surface and no sediment formation in the brake fluid.

Resultatene vist under for korrosjonstesten i samsvar med SAE J 1704 (Jan. 97) bekrefter også at bremsevæsker ifølge oppfinnelsen, slik som BF 2a, som har et lavt 1 H-1,2,4-triazol innhold gir fordeler i forhold til formuleringer som ikke er i samsvar med oppfinnelsen, slik som BF 1 d, som har et høyt 1 H-1,2,4-triazolinnhold, siden de utviser et bedre korrosjonsresultat i tilfelle kobber (BF 1 d tilsvarte BF 1, men omfattet 0,20 vekt-% 1 H-1,2,4-triazol i stedet for 1H-1,2,3-tolutriazol og omfattet kun 54,85 vekt-% trietylenglykol monometyleter borat): Resultatene fra korrosjonstesten i samsvar med SAE J 1704 (Jan. 97) er vist i Tabell 2 under. The results shown below for the corrosion test in accordance with SAE J 1704 (Jan. 97) also confirm that brake fluids according to the invention, such as BF 2a, which have a low 1 H-1,2,4-triazole content offer advantages over formulations which are not in accordance with the invention, such as BF 1 d, which has a high 1 H-1,2,4-triazole content, since they show a better corrosion result in the case of copper (BF 1 d corresponded to BF 1, but comprised 0.20 wt% 1H-1,2,4-triazole instead of 1H-1,2,3-tolutriazole and comprised only 54.85 wt% triethylene glycol monomethyl ether borate): The results of the corrosion test in accordance with SAE J 1704 (Jan .97) is shown in Table 2 below.
