All testing in standard conditions to this specification shall be performed in accordance with GMW3221, “Procedure for Standard Conditions of Or
6、ganic Materials”. Tests shall be conducted 40 h minimum after molding and immediately following a conditioning period of 24 hours minimum at 22 3C and 50 5% RH unless otherwise specified. All tests shall be performed on unannealed specimens. In addition, tests specified at temperatures below or abov
7、e 22 3C shall be conducted at the specified temperature using specimens conditioned at the specified temperature for 4 hours minimum. Test specimens shall be 1.8 0.2 mm thick unless otherwise specified. Property values are the average of an equal number of specimens cut from both the longitudinal an
8、d transverse plaque directions. The minimum values specified in the property tables must be met by test specimens in natural, black, or in a standard sampled color if natural or black are not available. For colored grades where other pigment and additive systems (e.g. stabilizer) are used, the impac
