ASTM D2527-83(2022)

Anotace textu normy ASTM D2527-83(2022) :

This specification covers splices in vulcanized rubber-seal material of any size, type, or cross-sectional shape having applications in services of all degrees of severity. The splices under this specification are divided into three classes based on splice strength and the appearance of the seal. Under Class 1 are splices in seals having an irregular cross section or are made of polymers not conducive to a high-strength splice, and hence are appropriate for applications with moderate service requirements. Splices under Class 2 are those found in solid seals having a shape and composition conducive to a high-strength splice, and hence are appropriate for applications with high service requirements. Class 3 is comprised of splices in round solid seals conducive to extra-high-strength splices. Splices under this class are appropriate for applications with difficult service requirements; that is, applications requiring splices of extra-high tensile and bend strength. Quantitative destructive and qualitative nondestructive tests shall be performed on the spliced area of the seal and shall conform to the physical requirements specified, in particular the ultimate elongation for the seal area.
