What is ISO 9455 ‑ 16 - Soft soldering fluxes about?
ISO 9455 ‑ 16 specifies a method for the assessment of the efficacy of a soft soldering flux, known as the wetting balance method, and gives a qualitative assessment of the comparative efficacy of two fluxes based on their capacity to promote the wetting of a metal surface by liquid solder. The method in ISO 9455 ‑ 16 is applicable to all flux types in liquid form classified in ISO 9454-1. NOTE: It is hoped that future developments using improved techniques for obtaining a r...
