标准摘要
[中文适用范围]: 本文件规定了三种测定焊料助焊剂中离子卤ide(不包括氟化物)含量的定量方法。卤ides按氯化物计算。还描述了一种有用的颜色测试法,用于检测离子卤ides。方法A是一种电位滴定法,适用于ISO 9454-1定义的焊料类别1和2。该方法被认为是这些焊料的参考方法,通常适合质量分数在0.05%到2%之间的卤ide含量(以非挥发性物质为基础)。方法B是测定水溶性助焊剂中总卤ide含量(不包括氟化物)的方法,适用于ISO 9454-1定义的类别2122至2124、3112至3114和3212至3214。方法C是测定含磷酸盐的水溶性助焊剂中卤ide含量的方法,适用于ISO 9454-1定义的类别331。方法D是一种定性测试法,使用铬酸银试纸检测离子卤ides的存在。该技术可用于所有类别的焊料。 [外文原描述]: This document specifies three quantitative methods for the determination of the ionic halide (excluding fluoride) content of soldering fluxes. Halides are calculated as chlorides. A useful qualitative test method for the detection of ionic halides is also described. Method A is a potentiometric titration method for the determination of halide (excluding fluoride) content and is applicable to flux classes 1 and 2, defined in ISO 9454 - 1 . This method, which is considered the reference method for these fluxes, is suitable for halide contents generally within the range of 0,05 % mass fraction to 2 % mass fraction in the non-volatile matter of the flux. Method B is a titration method for the determination of the total halide (excluding fluoride) content of water-soluble fluxes. It is applicable to flux classes 2122 to 2124, 3112 to 3114 and 3212 to 3214, as defined in ISO 9454 - 1 . Method C is a titration method for the determination of the halide (excluding fluoride) content of water-soluble fluxes containing phosphates and is applicable to flux class 331, as defined in ISO 9454 - 1 . Method D is a qualitative test, using silver chromate test paper, for the presence of ionic halides. The technique can be used for all classes of flux.
