7、:2003 ii BSI 14 February 2003 Foreword This British Standard has been prepared by Technical Subcommittee SW/14/3. This standard applies to floor mats for combat sporting use and is based on BS 1892-2.10:1990, which was withdrawn in 2001. This document is readily identifiable with the above withdrawn

8、 British Standard but having all references to fire resistance and fire testing deleted. The specification for fire safety requirements for mats, mattresses and landing areas is now specified under BS 1892-3:2003. In addition, all references which have been applied to the sport of judo in BS 1892-2.

9、10:1990 are specifically excluded from this standard. The specifications for judo mats are now specified under the BS EN 12503 series (this series includes seven parts). This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct app

10、lication. 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, pages 1 to 9 and a back cover. The BSI copyright notice displayed in this document indicates when the

11、 document was last issued.BS 1892-4:2003 BSI 14 February 2003 1 1 Scope This British Standard specifies safety requirements, test procedures and performance levels for combat mats, other than those for judo, which are contained in the BS EN 12503 series (which includes seven parts). NOTE Recommendat

12、ions for the use and storage of combat mats is given in Annex A. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced docume

15、ility ability of a mat to provide a surface upon which controlled movements can be made NOTE Athlete stability is only achieved within specific ranges of frictional and deformation properties. 3.3 combat matany mat which is used for karate, jujitsu, aikido, taekwondo and other forms of martial arts

16、NOTE The term “combat mat” does not refer to judo mats, which are covered in BS EN 12503-3, BS EN 12503-4, BS EN 12503-5, BS EN 12503-6 and BS EN 12503-7. 3.4 upper surface surface normally facing the user when the mat is in use 3.5 reverse surface surface normally in contact with the floor when the

17、 mat is in use 4 Dimensions When measured in accordance with Annex B, the dimensions of the combat mats shall be as given in Table 1, subject to the tolerances given in Table 2. The diagonals of combat mats to be used in a close-fitting array shall also conform to the tolerances shown in Table 2. NO

18、TE 1 It is essential that there is no gap between combat mats fitted in area. The tolerances specified in Table 2 will not necessarily guarantee this situation. It is therefore desirable that combat mats purchased are in one lot. The attention of the manufacturer should be drawn to the fact that suc

19、h combat mats are intended to be fitted in this way. NOTE 2 Thickness is not specified in Table 1 but will be fixed for particular constructs by the level of performance as shown in Table 3. Preferred thickness may be specified by the appropriate governing bodies for particular sports.BS 1892-4:2003

All subsequent production shall be subjected to such supervision and inspection procedures as to provide re

21、asonable assurance that the performance of each article when new is at least equal to that of the prototypes. 6.2 Performance The combat mat as a complete composite shall comply with Table 2, as appropriate, when tested in accordance with the methods specified herein. Infills shall conform to BS 337

22、9. SPECIAL NOTE ON 3.1 AND 3.2 The qualities of shock absorption and athlete stability are opposing criteria and the parameters of these two specifications are to be regarded as a compromise between the two criteria. 7 Marking Each article conforming to this part of BS 1892 shall carry a permanently

23、 attached and clearly visible label of minimum area of 4 000 mm 2 . The following wording 1)shall appear on a permanently attached label positioned such that it is clearly visible. a) “Complies with BS 1892-3:2003 for low risk hazard area”. or b) “Complies with BS 1892-3:2003 for high risk hazard ar

24、ea”. The letters of the wording shall be legible and of minimum height 2.5 mm. In addition the following information shall appear on the label: a complete identification of the product, including type, manufacturers reference number(s), name or trade mark.

27、2003 BSI 14 February 2003 3 Table 3 Properties of combat mats for sporting use Annex A (informative) Use and storage guidance A.1 Handling Mats should be handled with care to avoid damage to the filling or to the cover, which might expose the filling. Large or heavy combat mats or those of a bonded

28、construction should always be lifted by two persons to avoid excessive bending which can damage the bonding between surface cover and filler. Lifting and laying of combat mats is best achieved by using a trolley of size, strength and stability to suit the load, with castor wheels of suitable design

29、to enable the load to be correctly positioned in the store area. A.2 Use Permanently laid combat mats are likely to last considerably longer than removable ones. Combat mats should be aligned as they are laid, not pulled into position by their corners. If assemblies of combat mats are used, where po

30、ssible they should be laid from the centre of the finished area outwards. Recommended patterns can be obtained from the relevant sports association or the mat manufacturers. In use any creeping of combat mats should be corrected immediately to ensure that no gaps appear. A.3 Maintenance Anti-slip su

31、rfaces of combat mats should be cleaned periodically to maintain their efficiency. Upper surfaces should be wiped clean as required with a cleaning or disinfecting solution according to the manufacturers recommendations. Combat mats should be regularly checked for openings or tears in covers to ensu

32、re that the filling is not exposed and, if necessary, the mat taken out of use and the cover repaired in accordance with the manufacturers advice in order to avoid a greater risk of fire and user accidents. Mats with damaged surfaces and edges offer a far greater fire hazard and are more prone to ca

33、using user accidents. The playing of the sport itself rarely causes damage. Most damage occurs during handling and transportation. Dragging and excessive folding of combat mats are main causes of excess wear. Property Test procedure Parameter Peak deceleration (in m) Method 4 of BS 7044-2.2:1990 1.0

35、ise use the appropriate governing body should be consulted. a Use an impregnated chrome retanned leather as the test sole having a slip resistance value of 65 6 when tested against plate glass. b For this method: 1) use a wooden slider in place of the standard rubber giving a slip resistance of 35 6

36、 when tested against plate glass; 2) measure the mass of the mat under test to an accuracy of 0.1 kg; 3) frictional force is defined as mean slip resistance mass of mat (kg) 100 -BS 1892-4:2003 4 BSI 14 February 2003 A.4 Storage and fire precautions Stored combat mats present a hazard and it is impo

37、rtant that they are stored so that a fire occurring in them will not jeopardize means of escape from the premises. The following precautions should be observed: a) mats should be stored flat to present the least amount of surface area over which flame could travel vertically; b) they should be store

38、d separately from any easily ignited materials; c) storage should be tidy with access being maintained both to the store and within it; d) there should be no source of heat likely to ignite material within the store; e) luminaires within the store should be of the protected type, e.g. bulkhead or en

39、closed; f) the store should not form part of a general circulation area. Where a gymnasium or sports hall has access to a corridor either by a door or other opening forming an escape route from the hall or any other part of the building, the combat mats, in addition to those precautions already ment

40、ioned, should be kept in a separate store that can be secured against unauthorized use or interference. The store should not have direct access from the corridor and should be separated from it by imperforate and fire resisting construction of 1 h duration in accordance with BS 476-20, BS 476-21, BS

41、 476-22 and BS 476-23. Automatic smoke detection should be provided within the store linked to the main fire alarm system in the building. Ideally stores should be ventilated to the open air to the maximum area practicable, with ventilators operating by smoke detectors. Where small numbers of combat

42、 mats are to be used the provision of a purpose built store might not be warranted. If the risk of vandalism is low and an outbreak of fire would present no risk to other occupants of the building, combat mats may be stored in containers of robust construction made from non-combustible materials. Fu

43、rther details concerning recommendations associated with the use of cellular foam in sports and recreational facilities can be obtained from the Local Fire Authority and the Sports Council. A.5 Combat mats laid on a floor in the ready to use position When combat mats are laid out on a floor in use,

44、they are considered to present less of a fire hazard than when stored. Annex B (normative) Method for measuring dimensions B.1 Lay the combat mats to be measured upon a smooth, plane horizontal surface larger than the mat. NOTE If they show residual distortion from storage they may be allowed to res

45、t on the surface for 15 min and then smoothed by manual pressure to conform with the surface. B.2 In cases of dispute condition the mat at a temperature of 23 2 C, 50 5 % r.h. for a minimum of 16 h before measurement. B.3 Measure the length and width in accordance with BS EN ISO 1923, at points at l

46、east 100 mm from a corner, parallel to the edge. B.4 Measure the thickness in accordance with BS EN ISO 1923, but if no apparatus is available which conforms to this standard use a straight edge laid across the mat. NOTE The straight edge should be light enough so that the surface is not significant

47、ly deformed, and long enough to overhang the mat and its position should be such that the overhang at each end is equal. B.5 Use the straight edge at three locations and calculate the mean of the vertical gaps between the supporting surface and each end of the straight edge in each of its locations.

48、 The thickness is taken as the mean of six gaps.BS 1892-4:2003 BSI 14 February 2003 5 B.6 If measurements of the diagonals are required, make these measurements with the aid of two corner fences. Fix together the corner fences (each consisting of two plane arms at least 250 mm long, deeper than the

49、thickness of the mat) so that they stand perpendicularly to the supporting surface with an included angle of 90 . Lightly place one fence around each of one pair of diagonally opposite corners of the mat and measure the distance between the upper apices of the inside angles of the two fences.
