TR10 (ASTM D1329) and Tg (ASTM D7426) seek to give guidance as to when this occurs. Sealing has been shown to be possible below this temperature; which is reflected in part in the lower operating limit. The change to a glassy state is completely reversible, unlike the degradation that takes place at elevated temperatures. All seals have a finite life, the upper operating limit seeks to give a guide as to the point at which an appreciable life can be attained. Neither of these temperatures are absolute limits and short-term excursions are possible above the upper limit and in some situations sealing is possible below the lower limit; in certain cases far below.

Test Data - Methanol Immersion
Test Conditions
Five elastomer grades; A90H, G92E, V91K, V91A and Z95X were tested in 100% methanol.The test used BS1806-312 size O-rings. Test conditions were room temperature for 168 hours, with sampling intervals at 24hrs and 72hrs.
Test Procedure
- Specimens of each material were immersed in methanol liquid under ambient conditions.
- Volume was measured as per ASTM D297, and hardness as per ASTM D1414/1415; before immersion, at each interval and after 7 days immersion.
- Hardness change in points and volume change in percent was calculated as per ASTM D471.
