SOFT SOLDERING FLUXES - TEST METHODS - PART 10: FLUX EFFICACY TESTS, SOLDER SPREAD METHOD (ISO 9455-10:1998, IDT)
This Malaysian Standard specifies a method for the determination of the efficacy of a soft soldering flux. The method is known as the solder spread method and is applicable to all flux classes defined in ISO 9454-1.
NOTES
1 This part of ISO 9455 is only applicable for liquid fluxes > 10 % (m/m).
2 An alternative method for the determination of the flux efficacy, applicable to liquid fluxes only, known as the wetting balance method, is specified in ISO 9455-16.
