In 2018:

Following the publication of the new Edition EN 13480-1-2-3-4-5-6 and -8:2017 (so called "consolidated version") in June 2017, 3 additional Amendments EN 13480-2:2017/A1:2018, A2:2018 and A3:2018 have been published in October 2018 for Part 2 on "Materials".

Work organisation

The process used to deal with questions and modification requests is shown on the following diagram:

EN 13480/MHD is the central point to collect any queries from users of the standard. EN 13480/MHD is composed of European experts who were involved in the preparation of EN 13480 and any other experts nominated by CEN members.

Questions to be asked shall be written in English using the Template available on this EN 13480/MHD website.

The scope of EN 13480/MHD is limited to corrections and interpretations related to EN 13480. If EN 13480/MHD cannot solve a question, it is sent back to the relevant Working Group of CEN/TC 267.

Questions may result in technical amendments to EN 13480 which are dealt with by CEN/TC 267 according to the CEN rules (i.e. registration in CEN/TC 267 work programme, submission to vote).

The questions on EN 13480 with a proposed answer are sent by email to EN 13480/MHD experts:

When questions cannot be solved by email, they are discussed during meetings of EN 13480/MHD for final validation.

The questions are given in a chronologic order for each Part; for the questions still under discussion, no answer is shown. Answers to your questions about the current version of the standard can also be found in previous years' MHD answers about the former edition of the standard.

A new issue of EN 13480 is delivered each year; it includes the identified corrections and consolidates the Amendments adopted between two issues. The differences between the new Edition and the successive "Issues" will be indicated in Annex Y of each Part of EN 13480 and the changes are indicated in the relevant pages.

Every five years a new Edition (so called "consolidated version") is published with a new year.
