漆膜硬度檢測（ASTM第D3363號標準），應當至少能夠經受住F鉛筆的推劃。
人工老化試驗（ASTM第G23號標準），在陽光射線下暴曬5000個小時，在8號的每次ASTM第D659試驗的時候沒有脫落現象，且每經過一次STM D224的試驗退色不會超過5nbs，在凝露循環試驗下循環60/60個周期。
可延展性測試（ASTM第D1737號標準）：能夠經受1T到2T的彎曲。
光滑度測試（ASTM第523號標準）：在60度的光澤度計上有25-35%的反射率。
撞擊：當如下測試結束后，涂層沒有脫落。
用一把鋒利的刀從涂層到金屬平行地刻下6道或者更多道口子，每條刻痕間隔1.5毫米。
以相同方式交叉刻。
保留影響為東92厘米/公斤，或者是對準金屬的裂縫。
用玻璃紙膠帶粘在刻痕上，然后猛力拉開。
應當沒有涂層掉下。
