Viscosities for Groups 03, 04, 06, and 08 are measured as described as follows. Historical Version s – view previous versions of standard. A specific hazards statement is given in A superscript epsilon e indicates an editorial change since the last revision or reapproval. Voltage increments for the step-by-step test shall be determined from short-time test results as follows: This example can be applied to replace all table values, that is, tensile stress, notched Izod impact, and heat de?
It is possible that materials incorporating other pigments or soluble stabilizers, or both may prove adequate for particular applications. Weatherable nylon typically contains 1.
