GB/T 15972.32-2008 "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, specifies the test principle, equipment, sample preparation and operation steps, and regulates the measurement of key indicators such as peelability force. This standard provides a unified standard for accurately evaluating the peelability performance of optical fiber coatings, and helps to ensure the reliability and conformity of intermediate coating peeling during fiber processing and use.
