Information about this document

This is a full revision of the standard, and introduces the following principal changes:

• the scope has been modified to clarify that the guidance is for the selection and installation of products conforming to the BS EN 124 series as part of an in-service system; and
• to avoid conflict with the BS EN 124 series, the “specifications” for products that appeared in the previous edition have been removed, but where appropriate have been re-drafted as current industry practice to preserve useful information.

This publication can be withdrawn, revised, partially superseded or superseded. Information regarding the status of this publication can be found in the Standards Catalogue on the BSI website at bsigroup.com/standards, or by contacting the Customer Services team.

Product certification. Users of this British Standard are advised to consider the desirability of obtaining third-party certification of conformity with BS EN 124‑1:2015 to BS EN 124‑6:2015 for products they intend to install.

Use of this document

As a guide, this British Standard takes the form of guidance and recommendations. It should not be quoted as if it were a specification or a code of practice and claims of compliance cannot be made to it.

Presentational conventions

The guidance in this standard is presented in roman (i.e. upright) type. Any recommendations are expressed in sentences in which the principal auxiliary verb is “should”.

Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element.

Where words have alternative spellings, the preferred spelling of the Shorter Oxford English Dictionary is used (e.g. “organization” rather than “organisation”).
