This document specifies a distillation method for the determination of the ammonia content of solid, paste or liquid fluxes. The method is applicable to fluxes of class 311 and 321 only, as defined in ISO 9454‑1.
Abstract
Overview
EN - “Soft soldering fluxes - Test methods - Part 9: Determination of ammonia content” - specifies a validated for measuring ammonia in solid, paste or liquid soft‑soldering fluxes. The procedure applies only to fluxes of as defined in . The standard is intended for use by testing laboratories and manufacturers to quantify ammonia expressed as mass % of ammonium chloride.
