Annex A (informative) Method for the preparation of standard
                       reference rosin (colophony) based
                       liquid fluxes, having 25% (m/m)
                       non-volatile content
Annex ZA (normative) Normative references to international
                       publications with their relevant European
                       publications

The method specified is based on evaporating a weighed amount of the flux sample in an ebulliometer until the entire volatile part is driven off, which is determined by following the graph of distillation temperature against time. The flux residue is considered as the non-volatile content of flux. Applies only to flux with a non-volatile content of 10 % or more.
