标准范围

ISO 1520:2006规定了一种经验性测试程序，用于评估油漆、清漆或相关产品的涂层在标准条件下通过压痕逐渐变形时对金属基底的开裂和/或分离的抵抗力。对于多涂层系统，可以单独测试每个涂层，或者可以测试整个系统。该方法可以如下进行:作为“通过/失败”测试，通过测试到指定的压痕深度以评估是否符合特定要求；或通过逐渐增加压痕的深度以确定涂层破裂和/或从基底分离的最小深度。

ISO 1520:2006 specifies an empirical test procedure for assessing the resistance of a coating of paint, varnish or related product to cracking and/or detachment from a metal substrate when subjected to gradual deformation by indentation under standard conditions.For a multi-coat system, each coat may be tested separately or the complete system may be tested.The method may be carried out as follows:

• either as a 'pass/fail' test, by testing to a specified depth of indentation to assess compliance with a particular requirement;
• or by gradually increasing the depth of indentation to determine the minimum depth at which the coating cracks and/or becomes detached from the substrate.
