ASTM D2061: ASTM D2061 (拉链强度试验方法)
An American standard of test methods for zipper strength, covering pull strength, tooth strength, top and bottom stop strength and slider pull-off. It defines specimen preparation, gripping, test speed and result calculation so laboratories produce comparable data. The methods help buyers set acceptance limits and compare suppliers. Results depend on conditioning and clamping, so samples are equilibrated and tested in a controlled environment with calibrated equipment.
