This standard specifies quality grades, inspection methods, sampling rules, and judgment methods for flexible graphite metal wound gaskets. Gaskets are classified into three grades: qualified, first-grade, and premium, with defined performance indicators including compression rate, recovery rate, stress relaxation rate, and seal leakage rate. Inspection and sampling follow JB/T 6369-1992, with strict judgment rules: any non-conformance leads to rejection, and cross-grade items are judged by the lowest grade. This internal-use standard is essential for quality control and grading of gasket products.
