User trials by hospital and fire brigade staffs h
9、ave encouraged the adoption of a specification for non-traditional constructions. The latter are being published as Parts of BS4973 as follows. Part 1: Nonwoven sew-in interlinings; Part 2: Nonwoven fusible interlinings; Part 3: Woven and knitted fusible interlinings. It is intended that the fabrics
10、 in this standard should be used in conjunction with the outer cloths specified in BS1771 “Outdoor uniform cloths for fire service, local authority and hospital staffs”. Certification. Attention is drawn to the certification facilities described on the inside back cover of this standard. A British S
11、tandard 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 comprises a front cov

This will be indicated in the amendment table on the inside front cover.BS4973-3:1976 BSI 12-1999 1 1 Scope This
13、Part of this British Standard specifies requirements for woven and knitted fusible interlinings for uniform clothing for large users such as Government departments, fire services, hospitals and local authorities. Technical requirements are given inTable 1 and the materials are listed inTable 2 accor
14、ding to the garments for which they are recommended. 2 References The titles of the British Standards referred to in this standard are listed on the inside back cover. 3 Definitions For the purposes of this Part of this British Standard the following definitions apply. 3.1 strike-through penetration
15、 of the adhesive from the interlining to the face of the outer fabric 3.2 strike-back penetration of the adhesive to the outer surface of the interlining 4 Fusing Fusing instructions shall be supplied with the interlining and these shall be followed exactly by the maker-up. There shall be no strike-
16、through, and strike-back shall not be such as to cause subsequent adhesion to the lining and/or pocketing. Allow at least24h to elapse between fusing operations and carrying out tests. 5 Technical requirements 5.1 The mass per unit area of the fusible interlining most suitable for use with the outer
17、 fabric shall be agreed between the purchaser and the manufacturer and shall be within one of the ranges given inTable 1. The mass per unit area so agreed shall be subject to a tolerance of 10%. 5.2 Resistance to dry cleaning of the laminate bond (i.e.outer fabric plus interlining) shall be assessed
18、 by subjecting each specimen three times to the treatment described in BS4961, which gives two methods of test for dry cleaning (including steam finishing). The laboratory procedure is intended primarily for screening and control testing and in cases of dispute the machine procedure shall be used. 5
19、.3 Dimensional change on cold water immersion shall be limited as shown inTable 1. 5.4 To withstand normal handling tensile strength in the warp direction shall be not less than that shown inTable 1. 5.5 Peel bond strengths vary according to the construction of the outer fabric and type of finish th
20、e cloth has received. It is not practicable to specify a minimum strength that will be adequate for all the fabrics listed in BS1771. It is therefore recommended for quality control purposes that the peel bond strength shall be as agreed between the purchaser and the supplier, according to the speci
21、fic fabric and fusing method involved. A method for determination of peel bond strength is given inAppendixA ofBS4973-2:1973.

There shall be no appreciable change in handle of the laminate after dry cleaning. 6 Marking Each
24、interlining in the finished state shall be identified with the British Standard reference number, either by stamping or by labelling the tag-end of the piece.

A licence to use the Kitemark on or in relation to a product will be granted to any manufacturer or producer who demonstrates t
30、hat he can and will be able consistently to make that product to a specified British Standard. His capability of doing so is initially assessed by inspection of his production process, quality control organization and test facilities, and by independent testing of a sample of the product against all
31、 the criteria of the relevant standard. The licensee is required to accept, and to operate in accordance with, a BSI scheme of supervision and control which identifies the tests to be carried out during manufacture and on the completed product, and specifies the frequency of such testing. BSI carrie
32、s out unannounced inspection visits to the manufacturers works and audit testing of the product, and may withdraw the licence for any failure of the manufacturer to comply with the relevant standard or with the requirements of the scheme of supervision and control. The presence of the Kitemark on or
33、 in relation to a product is an assurance that the goods have been produced under a system of supervision, control and testing, operated during manufacture and including periodical inspection of the manufacturers works in accordance with the certification mark scheme ofBSI.
