This Commented Version (CMV) is a specialized publication featuring detailed commentary from technical experts on the major changes between the new edition of this standard and the previous one.
Comments may include an explanation for the changes as well as information on the impact of these changes on the application and usability of the standard.
Please note, the CMV of the standard is not adopted, and therefore doesn’t contain an additional national foreword, or national annex that might be contained in the BS adoption of the standard. However the IEC text that forms the content of the standard is identical to the BS adoption of the standard. You can purchase the BS adoption of the standard document here.
