防腐涂料检测

防腐涂料检测项目及执行标准根据具体国家和地区的要求可能会有些许差异，下面是一些常见的防腐涂料检测项目及其执行标准：

1. 干燥膜厚度测定：采用ASTM D 7091-13 "Standard Practice for Nondestructive Measurement of Dry Film Thickness of Nonmagnetic Coatings Applied to Ferrous Metals and Nonmagnetic, Nonconductive Coatings Applied to Non-Ferrous Metals"标准进行测定。

2. 耐盐雾腐蚀试验：采用ASTM B 117-16 "Standard Practice for Operating Salt Spray (Fog) Apparatus"或ISO 9227：2017 "Corrosion tests in artificial atmospheres — Salt spray tests"标准进行测试，以评估涂层抗腐蚀性能。

3. 粘结强度测定：采用ASTM D 4541-17 "Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers"标准进行测试，以评估涂层与基材之间的粘结强度。

4. 柔韧性测试：采用ASTM D 522-13 "Standard Test Methods for Mandrel Bend Test of Attached Organic Coatings"或ISO 1519：2011 "Paints and varnishes -- Bend test (cylindrical mandrel)"标准进行测试，以评估涂层的柔韧性。

5. 硬度测试：常见的测试方法有帕氏硬度、巴氏硬度和铅笔硬度等，相关测试标准主要有ASTM D 3363-19 "Standard Test Method for Film Hardness by Pencil Test"和ASTM D 3363-19 "Standard Test Methods for Hardness of Organic Coatings by Pencil Test"。

6. 色差测定：采用ASTM D 2244-16a "Standard Practice for Calculation of Color Tolerances and Color Differences from Instrumentally Measured Color Coordinates"标准进行测定，以评估涂层的颜色稳定性。
