Soft soldering fluxes. Test methods - Flux efficacy tests, wetting balance method best-seller Micro organisms which could beBS EN ISO 9455 16: 2001 specifies a method for assessing the efficacy of a soft soldering flux, known as the wetting balance method. It gives a qualitative assessment of the comparative efficacy of two fluxes (for example, a standard and a test flux), based on their capacity to promote wetting of a metal surface by liquid solder. The method is applicable to all flux types in liquid form classified in BS EN 29454 1: 1994, ISO 9454 1: 1990. It is hoped
