At the time of publication of this British Standard,
11、no corresponding International Standard exists. This standard enables clothing offering protection against specific liquid chemical agents to be specified by making reference to BS 4724 for the assessment of the resistance of clothing materials to permeation by liquids and to BS 3546 which specifies
12、 requirements for coated fabrics. Although clothing made from other materials will not comply with this standard as a whole, the technical committee responsible for this standard has recognized that the type of application of a protective garment under consideration may nevertheless call for the use
13、 of, for example: a) coated fabrics other than those specified in BS 3546-1, BS 3546-2 and BS 3546-3; b) unsupported solid plastics or rubber in the form of film or sheet; c) fabrics of laminated construction; d) other air-impermeable materials. In such circumstances advice concerning the selection
14、of a suitable fabric should be sought from the suppliers of the material, attention being drawn to the requirements for making-up, performance, sizing and marking of garments that are given in this standard and to the recommendations of BS 7184 on selection, use and maintenance of chemical protectiv
15、e clothing. Similarly, in the case of gloves that are integral to gas-tight suits, the specification calls up relevant clauses in BS 1651 to specify the characteristics of gloves made from PVC or the more common types of rubber. Hence the use of other materials of construction will not enable the su
16、it as a whole to comply with this standard. Subject to this understanding, if there is a call in special circumstances for the use of gloves made of other materials, guidance to their selection should be sought from the suppliers or manufacturers in the light of the recommendations of BS 7184. The s
17、pecification includes requirements for the performance of seams and of closures in the garments. The specification is intended for the use of manufacturers and, as such, does not deal with conditions of use. Care in the selection of protective clothing is required to ensure effective protection. In
18、this respect, it is emphasized that protective clothing is not necessarily completely effective under all circumstances. Hence its performance should be tested by appropriate means so that the user may be aware of the extent of the protection that is available. The performance of protective clothing
19、 should also be assessed under practical conditions in order to assess the degree and duration of the protection that the clothing affords when subject to mechanical stress as well as to exposure to chemicals in the working environment. Other characteristics, such as flammability and static electric
20、al properties of the materials of construction should be taken into account as appropriate. In cases where there is a need to test an assembly of garments as a whole, the use of appropriate test techniques should be considered to enable the purchaser or user to foresee the performance of the clothin
21、g when exposed, for example, to sprays or splashes of liquids or to solids in powder form. Detailed guidance for the selection, use and maintenance of chemical protective clothing is given in BS 7184. Attention is drawn to the need for the fibre content to be given in accordance with Statutory Instr
22、ument 1986 No 26, Trade Descriptions, The Textile Products (Indications of Fibre Content) Regulations 1986.

26、he materials of construction, making-up, performance, sizing and marking requirements for garments which resist the permeation and penetration of liquids and/or gases and so provide protection of underlying clothing and of the skin against chemical agents. The types of garments covered by this speci
27、fication are sleeves, aprons, hoods combined with capes, coats, trousers, two-piece suits, one-piece suits (coveralls), air-supplied clothing and gas-tight suits. The specification is intended to apply to garments whose physical properties are such as to enable them to be re-used, if this is appropr
28、iate after cleaning or decontamination. The clothing specified is not intended to be worn directly next to the skin but is suitable for wearing on top of underwear or other work wear and for use as necessary in combination with appropriate respiratory, eye, ear, foot and hand protection. The require
29、ments of this British Standard are not intended to apply to garments or workwear (such as specified in BS 5426) that are commonly made from porous (air-permeable) materials for general industrial use, and which offer only limited resistance to permeation and penetration by liquids and gases. NOTE 1T
30、his specification has been prepared to take account of factors concerning protection of the skin against liquids and the entry of gases into the garment. The extent to which the garments specified thereby offer protection against the various hazards presented by contact with solids should be assesse
31、d by the manufacturer, as appropriate. NOTE 2Appendix A gives optional design features for closure assemblies. NOTE 3In cases when special garments are required to be made in sizes that lie outside the ranges provided for by the tables in clause 14, the manufacturer should agree size requirements wi
32、th the purchaser. NOTE 4The titles of the publications referred to in this standard are listed on the inside back cover. 2 Definitions For the purposes of this British Standard, the definitions given in BS 1903 apply, together with the following. 2.1 clothing the combined assembly of those garments
33、(see 2.2), the wearing of which affords protection to the skin NOTEThe primary function of individual garments may be to offer forms of protection other than protection of the skin as such. 2.2 garment an individual item of protective equipment, the wearing of which affords protection to the skin (s
34、ee note to 2.1) 2.3 hood combined with a cape a garment that completely covers the head, neck and portions of the shoulders or upper part of the body 2.4 air-supplied clothing clothing that is fitted with facilities for the entry of air which may provide for respiration and/or for thermal conditioni
35、ng of the wearer. Air supplied clothing may provide complete cover either to the whole or to part of the body according to the circumstances of use 2.5 gas-tight suit1) a one-piece garment with hood, gloves and boots which, when worn with self-contained or compressed air-line breathing apparatus2),
36、affords the wearer a high degree of protection against harmful liquids, dusts and gaseous or vapour contaminants 2.6 two-piece suit a suit which consists of a coat, jacket or other top garment and separate trousers and which covers at least the trunk, arms and legs but not the face, hands nor feet 2
37、.7 air-impermeable materials materials through which permanent gases cannot pass except by undergoing a process of solution 2.8 penetration the passage of chemicals, in any physical form, from the outside of the clothing to the inside via essential openings, fastenings, seams, overlaps between items
38、, pores and any imperfections in the materials of construction 2.9 permeation a combined process of molecular diffusion of a chemical through a solid material forming the whole or part of clothing and its desorption into a specified medium 1) See BS 4667-2 and BS 4667-3. 2) See BS 4667-3.

40、 BS 3546-3. Materials of construction shall not be known to cause skin irritation nor any adverse effect to health. NOTEThe material of construction should be as light and as flexible as is consistent with the need to provide effective protection and permit ease of work. 3.2 Resistance to permeation
41、 by liquids If garments are marked see clause 16 g) with a statement to indicate the extent that the clothing offers protection against specific chemicals and if such chemicals are liquids, the sources of information given by the manufacturer in accordance with clause 16 g) shall state the results o
42、f tests of the resistance to the material of construction to permeation by the same chemicals, determined in accordance with BS 4724-1 or BS 4724-2 (see clause 15). NOTEWhere a more precise assessment of the potential resistance of the material of construction to permeation is required, the method o
43、f BS 4724-2 should be applied so as to assess the breakthrough time after permeation and the amount of liquid that permeates thereafter and to observe the effects of the liquid on the materials of construction. 4 Sleeves Sleeves shall be tubular in construction and shall be designed to cover the for
44、earm and/or upper arm so as to fit over other work wear (such as that part of a glove as may extend over the wrist). If the entries at each end of the sleeve are elasticated, the elasticated section shall be covered by a wrap-over extension of the sleeve complete with adjustable grip. The upper clos
45、ure shall be sufficiently tight when closed so as to grip the underlying garment. NOTE 1The required elasticity may be obtained either by the use of a fabric that is inherently elastic or by the separate use of elastic materials, attached or inserted within the material of construction of the sleeve
46、. NOTE 2An example of a suitable design for a sleeve is given in Appendix B. 5 Aprons The dimensions and making-up of aprons shall comply with clauses 3 and 4 of BS 3314:1982. Aprons shall not be fitted with pockets nor drip troughs. NOTENote 1 to 3.2 of BS 3314:1982 is not applicable. 6 Hoods combi
47、ned with capes Suitable means (such as a draw string or an elasticated closure) shall be provided to cause the hood to fit the head. NOTE 1In cases where elastic properties may be adversely affected by exposure to chemicals see clause 16 g), elasticated sections should be protected by a suitable cov
48、ering. NOTE 2See Figure 3 for a typical design of a hood combined with a cape. 7 Jackets and coats 7.1 General Jackets and coats shall be capable of being closed to the neck. NOTE 1Jackets and coats may have an integral hood (see 7.5) and should be designed to overlap the trousers by at least 20 cm.
49、 NOTE 2If appropriate, a double cuff should be provided with the cuff being of sufficient length to allow the fitting of gauntlet type gloves. Both inner and outer cuffs should be elasticated or provided with other means of ensuring a close fit. NOTE 3A double thickness panel to act as reinforcement may be provided to the outside back of the suit to cover the area from shoulder to waist, so as to protect the suit against damage when breathing apparatus is worn. NOTE 4Suits may be fitted with reinforced elbows and knees. 7.2 Collar A collar, if provided, shall be
