Approved Solders and Fluxes
Those solders and fluxes that are approved in the area of Installation are collected in table 1. Pb and Cd free solder alloys are used for both soft and hard soldering. The soft solders you meet primarily on the solder of the type S-SnAg3. This solder is very often used together with the flux 3.1.1 as solder paste, whereas solder is added additionally during soldering.
