APPLICATION This specification was released originally to be used in conjunction with industry standards or material specifications to provide a coherent structure for all environme

3、ntal testing of elastomeric parts. An elastomeric part is defined as a material with a Durometer A hardness of 90 and below (Such as Soft TPEs TPE-V, SEBS, TEEE, TPU, etc) which fall in the 2D category. Testing must be conducted on parts when possible. See Table 1 for sample size and testing require
