标准摘要
[中文适用范围]： ISO 8502 的这一部分描述了一种评估已清洁并准备涂漆的钢表面上残留灰尘的方法。它提供了用于评估灰尘平均数量的图形评级。它还提供了用于评估灰尘颗粒平均大小的描述性等级。所述方法是一种定性测试，适用于清洁前的钢表面，对应于 ISO 8501-1 中定义的锈蚀等级 A、B 或 C。它可以用作“通过/失败”测试或提供表面上存在的灰尘的永久记录。注：ISO 8502 的这一部分中引用的数量评级和尺寸等级源自 ISO 4628-1。 [外文原描述]： ISO 8502-3:2017 describes a method for the assessment of dust remaining on cleaned steel surfaces prepared for painting. It provides pictorial ratings for the assessment of the average quantity of dust. It also provides descriptive classes for the assessment of the average size of the dust particles. The method described is a qualitative test useful for a steel surface, before cleaning, corresponding to rust grade A, B or C as defined in ISO 8501‑1. It can be used as a "pass/fail" test or to provide a permanent record of the dust present on a surface.
