Foreword

This part of BS 5041 was originally published as BS 3980. However, while the metricated version of BS 3980 was being prepared, it was decided that it would be logical to issue the revised edition as Part 5 of BS 5041 “Fire hydrant systems equipment”. Parts 1 to 4 of BS 5041, the titles of which are given below, are at present in course of preparation.

Part 1: Landing valves for wet risers;
Part 2: Landing valves for dry risers;
Part 3: Inlet breechings for dry risers;
Part 4: Boxes for landing valves for dry risers.

This standard was originally proposed by the London Fire Brigade and has been prepared under the authority of the Fire Standards Committee to provide detailed specifications for most of the special requirements for wet and dry risers and foam inlets described in BS 5306‑1.

This part of BS 5041 supersedes BS 3980:1966 and is intended to fulfill the same purpose as that standard, that is, to define the standard sizes and details of boxes for foam inlets and dry riser inlets so as to enable architects and builders to specify a standard product in metric terms. The metric values are given in SI units; for further information on these, reference should be made to BS 3763 “The International System of units (SI)”.

The work sizes have been selected to conform to the first or second preferences in BS 4011

“Recommendations for the co-ordination of dimensions in building. Basic sizes for building components and assemblies” and this has led to a slight reduction in the maximum permissible size of the box compared with that specified in BS 3980.

The boxes can also be used for other purposes, e.g. for fuel oil inlets and inlets for drencher systems.

A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application.

Compliance with a British Standard does not of itself confer immunity from legal obligations.
