Foreword

Publishing information

This part of BS 8000 is published by BSI Standards Limited, under licence from The British Standards Institution, and came into effect on 31 January 2023. It was prepared by Technical Committee B/544, Plastering, rendering, dry lining. A list of organizations represented on this committee can be obtained on request to the committee manager.

Supersession

This part of BS 8000 supersedes BS 8000‑8:1994 and BS 8212:1995, which are withdrawn.

Relationship with other publications

BS 8000 is a series of standards describing the execution of works for a range of construction activities. They are issued to fill a gap in the authoritative information that is available to those specifying, supervising and instructing in connection with those activities and to assist in describing processes to ensure a better and common understanding of them and so improve construction quality.

The various parts of BS 8000 draw content from, and relate to, other relevant British Standards and codes. This part of BS 8000 makes recommendations and gives guidance on dry lining systems. It is intended to be read in conjunction with BS 8000‑0, which encourages liaison between and awareness of adjoining/dependent trades and processes in the construction sequence (whether or not they are subject to one of the specialist titles in the series).

Information about this document

Text introduced or altered by Corrigendum No. 1 is indicated in the text by tags . Minor editorial corrections are not tagged.

This document applies to the construction of dry lining using gypsum plasterboards manufactured to BS EN 520, BS EN 14190 and BS EN 13950, and metal framework components manufactured to BS EN 14195 and BS EN 13964.

The recommendations given are not fully comprehensive as particular project documents, e.g. project specifications might need to cover recommendations not dealt within this document. This document might not be applicable to the use of some proprietary systems.

The purpose of BS 8000‑8 is to encourage good design and workmanship by providing:

guidance for designers on the selection of systems;
guidance for installers on the correct sequence and method of installation; and
updated tolerances reflecting use and material installation and methods of measurement.

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

clarification of tolerances;
advice when installing dry lining to Steel Framing Systems (SFS);
testing of dry lining systems; and
expansion of relevant performance recommendations.

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 knowledge.bsigroup.com, or by contacting the Customer Services team.

1 Scope

This part of BS 8000 provides recommendations for the design and installation, including workmanship and finishing, of dry lining systems using gypsum-based plasterboards.

NOTE The general principles of workmanship on construction sites are given in BS 8000‑0.

It covers the performance-critical aspects of the components and workmanship used in dry lining systems such as separation, fire protection, stability, applied loadings, acoustics, thermal insulation and aesthetics. It covers the impacts on performance such as design considerations, site conditions, tolerances and penetrations and defines the clear and repeatable measurement of tolerances and deviation methods. The document is intended to be easy for the delivery team to use and understand and can be used for education and training purposes.

It is applicable to the construction sector, in relation to dwellings, non-dwellings, new builds and refurbishments.

It is for use by manufacturers, suppliers, specifiers, designers, contractors, installers, project managers and all Construction (Design and Management) Regulations (CDM) duty holders. It is also applicable to anyone with a vested interest in the end quality and performance of the dry lining, as well as building control clients and their teams.

It does not cover the installation of dry lining to systems constructed from light gauge steel framing (LGSF).
