This is a national product standard for the high-performance specialty engineering plastic—polyetheretherketone (PEEK) resin, which comprehensively specifies its technical requirements, test methods, inspection rules, packaging, storage, and transportation. The standard covers key performance indicators for evaluating PEEK materials, including melt flow index, thermal properties, mechanical properties, and electrical properties. To accurately determine these characteristics, the standard mentions or implies a wide range of testing instruments, including differential scanning calorimeters for thermal performance analysis, universal testing machines for mechanical testing, high-temperature gel permeation chromatography for molecular weight characterization, melt flow rate testers for measuring melt flow rates, and densimeters and electronic analytical balances for evaluating material density and water absorption.
