耐腐蚀性人工汗试验 Artificial Perspiration Corrosion Resistance

检测标准依据 Test Basis Standard：GB/T 38020.2-2-19《表壳体及其附件金合金覆盖层第2部分纯度、厚度、耐腐蚀性能和附着力的测试》

“Watch Cases and Accessories - Gold Alloy Coatings - Part 2: Testing for Fineness, Thickness, Corrosion Resistance and Adhesion”

用途：适用于金属表带、表壳、柄头的耐人工汗腐蚀性能试验。

This standard specifies test methods for evaluating the resistance to artificial perspiration corrosion of gold-plated components in metal watch bands, cases, and crowns.

试验原理：利用人造汗水在高温（40±2）℃环境下接触待测物，经过较长时间（不少于24小时）后，观察其表面的情况，以此判断其耐汗水腐蚀的情况。

Test Principle: Specimens are exposed to synthetic perspiration at 40°C ±2°C for a minimum duration of 24 hours. Post-exposure surface degradation (corrosion, discoloration, blistering) determines compliance.
