Test methods for electrical materials, printed board and other interconnection structures and assemblies - General test methods for materials and assemblies. Process ionic contamination testing (PICT)1 Scope This part of IEC 61189 is a test method designed to determine the proportion of soluble ionic residues present upon a circuit board, electronic component or assembly. The conductivity of the solution used to dissolve the ionic residues is measured to evaluate the level of ionic residues.

Emission requirements have been selected so as to ensure that disturbances generated by the apparatus operated normally on railway rolling stock do not exceed a level which could prevent other apparatus from operating as intended

A new term "substrate" has been introduced

New table 4 containing values for the mechanical properties at room temperature
