11、Publishing information This part of BS 8213 is published by BSI and came into effect on 30 March 2007. It was prepared by Subcommittees B/538/1, Windows, and B/538/2, Doors, under the authority of Technical Committee B/538, Doors, windows, shutters, hardware and curtain walling. A list of organizati
12、ons represented on these committees can be obtained on request to their secretary. Supersession This part of BS 8213 supersedes BS 8213-4:1990, which is withdrawn. Relationship with other publications BS 8213 is published in two parts: Part 1: Design for safety in use and during cleaning of windows,
13、 including door-height windows and roof windows Code of practice; Part 4: Code of practice for the survey and installation of windows and external doorsets. This part of BS 8213 is intended to supplement British and European product standards for windows and doorsets. Information about this document
14、 This is a full revision of the standard. It brings up to date the guidance given in the previous edition and takes into account the publication of a number of European Standards published since 1990. Use of this document As a code of practice, this part of BS 8213 takes the form of guidance and rec
15、ommendations. It should not be quoted as if it were a specification and particular care should be taken to ensure that claims of compliance are not misleading. Any user claiming compliance with this part of BS 8213 is expected to be able to justify any course of action that deviates from its recomme
16、ndations. Due to the wide variety of installation conditions, it is not possible to cover all applications completely. This part of BS 8213 gives guidance on those good building practices that are expected to ensure satisfactory installation. Windows and external doorsets are available in a range of
17、 materials, each material having a unique performance characteristic. The surveyor and installer need to be aware of the material being used, and any additional manufacturers recommendations for survey and installation.

18、pr 02 00:22:30 GMT+00:00 2007, Uncontrolled Copy, (c) BSI BS 8213-4:2007 iv BSI 2007 Presentational conventions The provisions in this standard are presented in roman (i.e. upright) type. Its recommendations are expressed in sentences in which the principal auxiliary verb is “should”. Commentary, ex
19、planation and general informative material is presented in smaller italic type, and does not constitute a normative element. Contractual and legal considerations This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application
20、. Compliance with a British Standard cannot confer immunity from legal obligations. Attention is drawn to the Building Regulations 2000 and subsequent amendments 1, the Building (Scotland) Regulations 2004 2 and the Building Regulations (Northern Ireland) 2000 3, and to the need for Building Regulat
21、ions approval for the majority of window and external doorset installations. Licensed Copy: London South Bank University, London South Bank University, Mon Apr 02 00:22:30 GMT+00:00 2007, Uncontrolled Copy, (c) BSI BSI 20071 BS 8213-4:2007 1 Scope This part of BS 8213 gives recommendations for the s
22、urveying and installation of non-loadbearing windows and external doorsets of any material, to be installed vertically (within 15) into the external face of buildings. It gives guidance on the good practices necessary for the successful surveying and installation of windows and external doorsets in
23、both new build and replacement situations. It is primarily aimed at installations in dwellings but much of the guidance given is relevant to other types of installation. The guidance contained in this part of BS 8213 may also be applied to door assemblies, but does not cover the site assembly of ind
24、ividual components. This part of BS 8213 does not apply to load-bearing windows, load-bearing doorsets or roof windows. It does not cover curtain or ribbon walling, although its guidance also applies to separate window and door elements within those particular types of assemblies. It does not cover
25、good business practice issues such as warranties, complaints, etc. NOTE For roof windows or when the windows and external doorsets to be installed fall outside the scope of this part of BS 8213, e.g. non-rectangular products, it is necessary to seek specialist advice from the manufacturer. 2 Normati

39、 of components used in the fabrication of a window or doorset 4 Materials 4.1Fixings Fixings should be at least as corrosion-resistant as BS EN 1670:1998, Grade 3. 4.2Sealants The purpose of perimeter sealants is to repel water and prevent air leakage in the face of differential movement between the
40、 aperture and the window or doorset. Suitable sealants exhibit and retain flexibility and adhesion over this period. It is essential that sealants are compatible with the frame material and the substrate. The movement class for the sealant will depend on the substrate material, the frame material an
41、d the dimensions of the joint between the frame and the opening.

42、1600. Unless an unusual and specific known requirement determines otherwise, they should be of low modulus and high elasticity, with movement capability of at least 20%. These characteristics should be identified on their packaging as class 20LM or 25LM. NOTE 1 A guide to the use of BS EN ISO 11600
43、is given on The British Adhesives and Sealants Association website at . If a situation arises where the anticipated movement exceeds the performance criteria of a class 25 sealant, then the sealant manufacturer should be contacted for specific advice on sealant selection. NOTE 2 If in doubt, sealant
44、 manufacturers can be consulted on sealant adhesion to specific substrates and materials and on whether primers are required. They can also propose sealant/primer systems, which will minimize the potential for staining. A comprehensive list of UK sealant manufacturers can be found at . 4.3Finishing
45、trims All trims should be compatible with the material of the frame and should be colour matched where specified. Finishing trims, where used externally, should be good exterior quality materials used in accordance with the manufacturers instructions. Cellular extruded PVC-UE trims should conform to
46、 BS 7619. 5 Surveying for replacement windows and doorsets 5.1General NOTE 1 Attention is drawn to the legal requirement to identify the need for any planning permission, e.g. for listed buildings or in conservation areas. NOTE 2 An example of a surveyors checklist is given in Annex A. Good surveyin
47、g is the basis of ensuring a quality installation. Surveyors should be fully trained in window and doorset installation techniques, and in the manufacturers recommendations for the particular system being used. In order to demonstrate compliance with Building Regulations (see Note 3), it is advisabl
48、e to record the style of the window or doorset being replaced along with the size of any opening lights and the positions of any mullions and transoms. Ideally, this would be with the use of photographs and witnessed by the purchaser and countersigned. The surveyor should inform the purchaser of any
49、 enhancements that could be made with respect to any apparent security issues. NOTE 3 Attention is drawn to the Building Regulations 2000 and subsequent amendments 1, the Building (Scotland) Regulations 2004 2 and the Building Regulations (Northern Ireland) 2000 3.
