13、BS 7158:2001 ii BSI 08-2001 Foreword This British Standard has been prepared by sub-committee PRI/88/1, Thermoplastics piping systems and components for non-pressure applications. It is a revision of BS 7158:1989, which is now withdrawn. It comprises a specification for inspection chambers made of s
14、pecified plastics materials and is intended for use in the construction of drains based on rigid pipes and/or flexible pipes in accordance with BS EN 752. Annex A to Annex G are normative and give methods of test. Annex H is informative and gives guidance on the use and installation of plastics insp
15、ection chambers. Annex I is normative and introduces a method of test for resistance to negative pressure (for inspection chambers deep). Annex J is informative and gives guidance on quality control for the manufacture of plastics inspection chambers. Attention is drawn to BS 5955-6, which gives gui
16、dance on the installation, testing, cleaning and repair of unplasticized PVC pipework for gravity drains and sewers. Attention is drawn to BS 4346-3 and to BS 6209, which include requirements for cements suitable for jointing PVC-U pipes for non-pressure applications and are applicable to pipework s
17、ystems conforming to BS EN 1401-1. It has been assumed in the preparation of this British Standard that the execution of its provisions is entrusted to appropriately qualified and experienced personnel. This revision of the first edition of BS 7158 introduces the following principal changes. a) In c
18、lause 4, the materials allowed have been extended to include recycled material, as defined by BS ISO 472:1988, but controlled by adding an item f) to 4.2 with requirements similar to those which apply to reprocessed material, i.e. the material shall be a PE, PP or PVC-U traceable to a single source
19、of known origin. The definitions for reworked and recycled materials have been updated to align with the current edition of BS ISO 472. b) In clause 6, the choice of colour is now unrestricted, i.e. no longer confined to only brown or black. c) Subclause 7.8 and Annex I introduce additional requirem
20、ents for inspection chambers deep, incorporated from prEN 13598-1. d) In clause 8, the marking requirements have been modified with two objectives in mind: 1) to eliminate the need for all components of an assembly, e.g. riser and frame and cover, to each carry all the markings; 2) to eliminate the
21、final sentence of item f) which was subjective and not considered essential for relatively shallow chambers. e) References are updated to cater for withdrawn British Standards and/or the introduction of relevant BS ENs. Product certification/inspection/testing. Users of this British Standard are adv
22、ised to consider the desirability of third party certification/inspection/testing of product conformity to this British Standard. Appropriate conformity attestation arrangements are described in BS EN 45011. Users seeking assistance in identifying appropriate conformity assessment bodies or schemes
23、may ask BSI to forward their enquiries to the relevant association. Attention is drawn to the provisions of the Health and Safety at Work etc. Act 1974 and the need to ensure that appropriate precautions are taken to ensure the safety of personnel when carrying out methods of test required by this s
24、tandard. 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. Summary of pages This document c

26、6, Uncontrolled Copy, (c) BSI BS 7158:2001 BSI 08-2001 1 Introduction The publication of this British Standard as an individual standard is intended to avoid duplication of specification and confusion of marking of plastics inspection chambers used in drainage systems otherwise made of different mat
27、erials which may or may not be plastics. The chambers can be designed for use with one or more different systems made in accordance with other standards. Provision is made for marking integral connections on the chambers to indicate the system components and sizes, in accordance with other standards
28、 with which the connection is dimensioned, to allow direct connection as applicable. At least two of the systems with which such chambers are expected to be used, namely those specified in BS EN 295-1 and BS EN 1401-1, embody fundamentally different philosophies in respect of sampling requirements a
29、nd inspection systems. Attention is drawn to Annex J and to the advice concerning certification. Since BS 8301 is now obsolescent, attention is drawn to parts 1 to 7 of BS EN 752, which give recommendations for the design, construction and use of drainage systems, including inspection chambers, unde
30、r and around buildings and their connections to downstream systems. Attention is drawn also to BS EN 1610, which gives general requirements for testing of drains, including inspection chambers. This revision has been prepared taking into account the National Annex to BS EN 752-3:1997 which defines U
31、K national installation practice for underground drainage products. The 2000 version of that National Annex makes provision for the first time in the UK for having deep non-man-entry inspection chambers. This change was made to enhance the safety aspects of deep access by relying on more modern surf
32、ace-based techniques. Attention is drawn to Safe work in confined spaces 1, which encourages the use of non-man-entry inspection systems. The additional testing requirements added to this revision of BS 7158 allow chambers to be used at depths down to 6 m. 1 Scope This British Standard specifies req
33、uirements for plastics inspection chambers for use at depths to invert not exceeding 6 m in the construction of drainage and sewerage systems. It is applicable to non-man-entry chambers with or without raising pieces and having a nominal cross-section as recommended in Table NB.2 of BS EN 752-3:1997
34、, as amended in 2000. The chambers are classified into four grades as a function of stiffness (see 7.6) and strength (see 7.7), to suit different depths of installation and location for exposure to surface loading (see Annex H). Attention is drawn to BS EN 124:1994 and BS 4660 which specify requirem
35、ents for covers and frames for drainage purposes that are applicable to inspection chambers. This standard specifies materials, dimensions and tolerances, physical and performance characteristics and marking for plastics inspection chambers for drains and sewers. 2 Normative references The following
