User trials by hospital and fire brigade s
10、taffs have encouraged the adoption of a specification for non-traditional constructions. This is the first part of a three part standard which deals with: Part 1: Nonwoven sew-in interlinings; Part 2: Nonwoven fusible interlinings; (in preparation) Part 3: Woven fusible interlinings. (in preparation
11、) It is intended that the fabrics in this specification should be used in conjunction with the outer cloths inBS1771, “Outdoor uniform cloths for fire service, local authority and hospital staffs”. A British Standard does not purport to include all the necessary provisions of a contract. Users of Br
12、itish 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 cover, an inside front cover, pages i and ii, pages1 and 2, an inside back cover and a back co
13、ver. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS4973-1:1973 BSI 11-1999 1 1 Scope This Part of this British Standard specifies requirements for nonwoven sew-in interlinings fo
14、r uniform clothing, for large users such as Government departments, fire services, hospitals and local authorities. Technical requirements are tabulated inTable 1; the materials are listed in Clause4 according to the garments for which they are recommended. NOTEThe titles of the British Standards re
15、ferred to in this standard are listed on the inside back cover. 2 Technical requirements When tested by the methods indicated in the second column ofTable 1, the mass per unit area, bursting strength, crease recovery, change in stiffness, dimensional change on cold water immersion and dry cleaning r
16、equirements shall be as specified in the fourth, fifth, sixth and seventh columns ofTable 1. Two methods of test for dry cleaning (including steam finishing) are available. The laboratory procedure is intended primarily for screening and control testing and, in case of dispute, the machine procedure
17、 shall be used. For purposes of general comparison in respect of handle not specified in this British Standard, agreement shall be reached between the purchaser and the manufacturer. 3 Marking Each interlining in the finished state shall be identified with the British Standard reference number, eith
18、er by stamping or by labelling the tag end of the piece. NOTEAttention is drawn to certification facilities offered by BSI. See the inside back cover of this standard. 4 Uses These interlinings are recommended for: These recommendations are for guidance only; they do not prohibit the use of these in
19、terlinings for other purposes. NW1: Raincoat Foreparts flaps, welts, cuffs, collars and pocket stays. NW2: Foreparts for jackets, overcoats and raincoats; chest pieces, waistbands, belts and pocket stays. NW3: Raincoat cuffs, flaps, welts, lapel pieces, pocket stays and shoulder straps. NW4: Forepar
