20、ng connectors within the scope of IEC technical committee 48. This test may also be used for similar components when specified in a detail specification. The object of this test is to define a standard test method to assess the solderability of the terminations of a component designed for use with p

21、rinted boards or for other applications using similar soldering techniques. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 60512. For dated references, subsequent amendments to, or revisions
