- the plaques are mounted on sample holders and subjected to natural weathering in Florida (45° South, direct, approximately 140 kLy/year). Periodically, the carbonyl content of the samples is measured with an infrared spectrophotometer. The exposure time corresponding to formation of a carbonyl absorbance of 0.5 is a measure for the efficiency of the stabilizer system.
- the synergistic effect of the two coadditivs is determined by a comparison of the calculated T 0.5 value with the actually measured T 0.5 value.

- the tapes are mounted without tension on sample holders and exposed in a WEATHER-OMETER Ci 65 (black panel temperature 63 ⁇ 2° C., without water-spraying). Periodically, the tensile strength of the exposed tapes is measured. The exposure time corresponding to a loss of 50% (T 50 ) of the initial tensile strength is a measure for the efficiency of the stabilizer system.
