Requirements for Soldering Fluxes with Amendment 1
The IPC J-STD-004C WAM1 standard prescribes general requirements for the classification and characterization of fluxes for high quality solder interconnections. The IPC J-STD-004C WAM1 standard may be used for quality control and procurement purposes. Soldering flux materials include the following: liquid flux, paste flux, solder paste, solder cream as well as flux-coated and flux-cored solder wires and preforms. It is not the intent of the IPC J-STD-004C WAM1 standard to exclude any acceptable flux or soldering material; however, these materials must produce the desired electrical and metallurgical interconnection.
