BSEN1015-21:2002

National foreword

This British Standard is the official English language version of EN 1015-21:2002. EN 1015-21 is the subject of transitional arrangements agreed under the Commission mandate. The Member States have agreed a nominal transition period for the co-existence of the future "harmonized" European Standards and their corresponding national standard(s). It is intended that this period will comprise a nominal nine month period during which any required changes to national regulations are to be made, followed by a further nominal twelve month period for the implementation of CE marking. At the end of this co-existence period, the national standard(s) will be withdrawn. There is no corresponding UK national standard. Because EN 1015-21 is a supporting standard to the forthcoming "harmonized" European product standard specification EN 998-1 (Specification for mortar for masonry-Part 1: Rendering and plastering mortar) then the above-mentioned co-existence period will commence upon the date of availability of EN 998-1. An estimation of the date of commencement of this period cannot yet be given.

The UK participation in its preparation was entrusted by Technical Committee B/519, Masonry and associated testing, to Subcommittee B/519/2, Mortar, which has the responsibility to:

• aid enquirers to understand the text;
• present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed;
• monitor related international and European developments and promulgate them in the UK.

A list of organizations represented on this subcommittee can be obtained on request to its secretary.
