41、aterial (appendix).5.Materials5.1GeneralPolyethylene plastics used to make tubing meeting the requirements of this specification are categorized by meansof two criteria, namely, (1) short-term strength tests, and (2) long-term strength tests.5.2Basic MaterialsThis specification covers PE tubing made
42、 from three PE plastics as defined in Specification D1248, inwhich the requirements are based on short-term tests of Grade P23, Grade P24, Grade P33, and Grade P34.
