For health & safety requirements, I am seeking an alternative test flux
to that prescribed for use in the solder testing of PCBs.

This test flux comprises 25% colophony in alcohol. 

Colophony is classed as a Sensitizing Agent for Occupational Asthma. 

LEV is an option but I would prefer to use a safe flux of similar
"activity".

 

Does anyone know of a colophony-free flux of similar activity? I regret
that I do not know the activity of the colophony flux (acid value?). Is
there a way of comparing it with the activity of a synthetic flux?

 

Many thanks in anticipation
