Abbreviations used within the titles of ISO standards are not included in this list.

Code of Ethics and Conduct

Set of principles to be followed by people involved in ISO work, e.g. working within an international framework, upholding consensus, being ethical.


This could be:

  • first party (assessment by manufacturer/supplier themself),
  • second party (assessment of manufacturer/supplier by user or purchaser),
  • third party (assessment of manufacturer/supplier by someone independent).

The goal of any technical committee: general agreement where there is no sustained opposition to substantial issues by any important part of the concerned interests, in a process that seeks to take into account the views of all parties concerned (see subclause 2.5.6 in the ISO/IEC Directives, Part 1).
