scope:

This Standard specifies the test methods for soldering fluxes (hereafter referred to as fluxes) mainly intended for connection of wiring and parts in electric and electronic apparatuses and communication devices.

WARNING Persons carrying out tests based on this Standard should be familiar with normal laboratory practice.

This Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this Standard to establish appropriate safety and health practices.

NOTE The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.
