金属和合金的腐蚀 真实结构和设备上气体和颗粒的擦拭法测量

[中文适用范围]： 本文件规定了一种通过擦拭法评估真实结构和设备上沉积物的方法。沉积物成为金属、合金和有机材料的腐蚀和/或降解因素，可以定量分析以控制真实结构和设备的腐蚀和降解。本文件规定的方法适用于评估所有行业中真实结构和设备上沉积物的类型和数量。该方法识别沉积物的类型，并给出水溶性和不溶性沉积物浓度的瞬时值，这些值以单位面积质量表示，不包含时间分量。这些值提供了与腐蚀和降解相关的环境因素的信息。该方法可用于检测水溶性沉积物，包括氯离子、硫酸根离子和其他离子，并可帮助用户了解加速腐蚀的协同和拮抗作用。本文件适用于： — 金属及其合金； — 金属涂层； — 有机涂层； — 混凝土和其他结构材料。 ISO 8502-2、ISO 8502-5、ISO 8502-6 和 ISO 8502-9 给出了清洁表面上氯化物的测定方法，该方法可确保钢基材在经过表面处理（例如研磨、抛光、清洁和冲洗）之后以及涂装之前保持清洁。 [外文原描述]： This document specifies a method for evaluating depositions on real structures and equipment by wiping. Depositions become corrosion and/or degradation factors for metals, alloys and organic materials, and can be analysed quantitatively to control the corrosion and degradation of real structures and equipment. The method specified in this document is suitable for evaluating the type and amounts of depositions on real structures and equipment in all industries. This method identifies the type of depositions and gives instantaneous values of the concentrations of water-soluble and insoluble depositions, which are expressed by mass per area without a time component. These values provide information on environmental factors related to corrosion and degradation. The method can be used to detect water-soluble depositions, including chloride ion, sulfate ion and other ions, and can assist users in understanding the synergistic and antagonistic effects that accelerate corrosion. This document is applicable to: — metals and their alloys; — metallic coatings; — organic coatings; — concretes and other structural materials. The method for determining chloride on clean surfaces, which ensures the cleanness of steel substrates after surface preparation such as grinding, polishing, cleaning and rinsing and before the application of paints, is given in ISO 8502-2, ISO 8502-5, ISO 8502-6 and ISO 8502-9.
