  • the test chamber consisted of a wind tunnel with a length of 18 m and a closed circuit.
  • the test chamber had 9 fans arranged in 3 rows of 3 fans each.
  • the chamber temperature could be set between 15 °C and 35 °C.
  • MeS was used as an irritant or simulant.
  • the vapor was generated in a controlled evaporator-mixer behind the exposure area so that the full length of the tunnel could be used to mix the vapor with the test room atmosphere.
  • the concentration was continuously and simultaneously monitored by a gas chromatograph with a flame ionization detector. While the concentration was being built up or the chamber was being flushed, the subject was not present in the chamber.
  • Permeated MeS vapor was determined by passive adsorption using passive samplers (PADs) composed of an impermeable polymer support and a polyethylene topsheet. The two layers are heat sealed together to form a sort of pouch filled with 80mg of Tenax TA 60/80 Mesh.
  • the methyl salicylate (MeS) penetrates the polyethylene layer at a certain speed and is adsorbed by the tenax.
  • the uptake rate of the PADs was measured in a separate PAD determination at low concentrations of MeS.
  • the amount of MeS adsorbed on the samplers was analyzed using thermal desorption and gas chromatography. The amount on the passive samplers was converted to the penetrated dose expressed in ml/min using the sampling rate of the samplers.
  • the measured penetration doses were normalized to the specified stimulus dose, expressed in mg•min/m 3 , especially since the actual test conditions (concentration and exact duration) can sometimes deviate slightly from the desired settings.
  • test results were reported as the protection factor provided by the garment at a specific location on the body.
  • the protection factors were also determined on the basis of the normalized penetration dose.
  • sampler pattern defined in the AEP-38 2012 version was used, i.e. some additional samplers were placed compared to the original ASTM F2588 sampler pattern.
