This standard was first published in 2003 and subsequently revised in 2018. This revision has been undertaken to align it with the latest version of ISO 3834-1 : 2021 under dual numbering system to harmonize it with the latest developments that have taken place at international level.

| Part 5 | Documents with which it is necessary to conform to claim conformity to the quality requirements of ISO 3834-2, ISO 3834-3 or ISO 3834-4 |
This edition cancels and replaces the previous edition, which has been technically revised. The main changes are as follows:
a) this document has been editorially revised; and
