Test methods for electrical materials, printed boards and other interconnection structures and assemblies - General test methods for materials and assemblies. Soldering flux for printed board assemblies1 Scope This part of IEC 61189 is a catalogue of test methods representing methodologies and procedures that can be applied to test printed board assemblies. This part of IEC 61189 focuses on test methods for soldering flux based on the existing IEC 611895 and IEC 611896. In addition, it includes test methods of soldering flux for lead free soldering.

NOTE 1 This test is an accelerated test because there is exposure to much higher than atmospheric levels of CO2 and is at a relative humidity conducive to a maximum rate of carbonation
