ISO 17652-2:2003描述了评估车间底漆对焊接性影响的试验。以下是详细的测试。 评级测试 该筛选试验提供了一种方法，通过制作标准焊缝，然后评估产生的气孔的严重程度，来评估指定厚度的车间底漆的相对可焊性。评级测试适用于供应商声明特定车间底漆和类似用途的影响。 焊接性试验 本试验描述了使用各种弧焊工艺评估焊接耗材和车间底漆组合的可焊性的方法。制作标准尺寸的圆角，以便进行比较。对合成焊缝的质量进行了全面评估。可焊性测试可能与生产过程中的实际情况更密切相关。

ISO 17652-2:2003 describes tests for assessing the influence of shop primers on the weldability. The following tests are detailed. Rating test This screening test provides a method of assessing the relative weldability of a shop primer of a specified thickness by making a standard weld and subsequently evaluating the severity of the resulting porosity. Rating tests are suitable for declaration by suppliers of the influence of particular shop primers and similar purposes. Weldability test This test describes a method for evaluating the weldability of welding consumables and shop primer combinations, using various arc welding processes. A standard size fillet is produced that enables comparison to be made. An overall assessment of the quality of the resultant weld is made. Weldability tests may be more closely related to actual conditions during production.
