本标准建立了一种实验室试验方法，用高压灭菌器在高温高压下评估特定环境中管材塑料涂层的性能。本标准旨在使实验室试验程序标准化，并有助于评估管状货物塑料涂层的一般性能。本标准由482任务组维护。

This standard establishes a laboratory test method for evaluating the performance of plastic coatings for tubular goods in specific environments at elevated temperatures and pressures by use of an autoclave. This standard is intended to standardize laboratory test procedures and aid in evaluating the general performance of plastic coatings for tubular goods. This standard is maintained by Task Group 482.
