漆膜硬度检测（ASTM第D3363号标准），应当至少能够经受住F铅笔的推划。
人工老化试验（ASTM第G23号标准），在阳光射线下暴晒5000个小时，在8号的每次ASTM第D659试验的时候没有脱落现象，且每经过一次STM D224的试验退色不会超过5nbs，在凝露循环试验下循环60/60个周期。
可延展性测试（ASTM第D1737号标准）：能够经受1T到2T的弯曲。
光滑度测试（ASTM第523号标准）：在60度的光泽度计上有25-35%的反射率。
撞击：当如下测试结束后，涂层没有脱落。
用一把锋利的刀从涂层到金属平行地刻下6道或者更多道口子，每条刻痕间隔1.5毫米。
以相同方式交叉刻。
保留影响为东92厘米/公斤，或者是对准金属的裂缝。
用玻璃纸胶带粘在刻痕上，然后猛力拉开。
应当没有涂层掉下。
