GB/T 15972.32-2021 "Specification for Optical Fiber Test Methods, Part 32: Mechanical Property measurement methods and test procedures, coating peelability", specifies the measurement methods and test procedures for the peelability of optical fiber coatings. Clarify the test principle, equipment, sample preparation and operation steps, standardize the measurement and judgment of key indicators such as peelable force, provide a unified standard for evaluating the peelable performance of optical fiber coatings, and ensure the standardization and stability of intermediate coating peeling operations during optical fiber processing and use.
