标准范围

本技术报告提供了有关水溶性氯化物和硫酸盐污染水平影响的信息在钢表面上，在按照标准机械或喷砂清理表面处理方法。注:不同油漆类型的水溶性盐污染公差可能不同。在涂漆前评估表面处理的充分性时，可使用该信息。本文件仅涉及基于实验室或现场的盐污染测量水平测试。本文件中讨论的可溶性氯化物和硫酸盐水平将使用可溶性根据ISO 8502-6（布雷斯勒法）萃取后测定的物种表面密度，或其他给出同等结果的方法。总可溶性盐污染可通过电导法测定测试，但此类测试不会确定存在的特定盐的性质和浓度，例如存在氯化物或硫酸盐，或其浓度。本文件未规定具体的清洁度或除盐方法。

This Technical Report provides information on the effect of water-soluble chloride and sulfate contamination levelson steel surfaces, before the application of paint or related products to surfaces prepared in accordance withstandard mechanical or blast-cleaning surface preparation methods.NOTE The tolerance for water-soluble salt contamination may be different for different paint types.This information may be used when evaluating the adequacy of surface preparation prior to painting.This document is concerned only with measured levels of salt contamination based upon either laboratory or fieldtesting. The levels of soluble chloride and sulfate discussed in this document are to be compared using solublesurface densities of the species as determined after extraction in accordance with ISO 8502-6 (the Bresle method),or other methods giving equivalent results. Total soluble-salt contamination may be determined by conductometrictesting, but such testing will not determine the nature and concentration of the specific salts present, e.g. whetherchloride or sulfate is present, or its concentration.This document does not define specific levels of cleanliness or methods of salt removal.
