本文件规定了用于软焊料的固体、液体和糊状焊剂的性能要求。 注1:ISO 9454-1规定了焊剂分类的标签和包装要求以及编码系统。 注2:用于惰性气体和气相焊接的一些助焊剂可能不符合表1和表2中的一些标准。 这些焊剂的要求由买方和供应商商定。

This document specifies the performance requirements for fluxes in solid, liquid and paste forms intended for use with soft solders. NOTE 1 ISO 9454‑1 specifies the requirements for labelling and packaging as well as the coding system for the classification of the fluxes. NOTE 2 Some of the fluxes intended for inert gas and vapour phase soldering may not pass some of the criteria in Tables 1 and 2. Requirements for these fluxes are agreed between the purchaser and the supplier.
