It is based on Part2 of the Sports
9、 Council Specification for Artificial Sports Surfaces,1984, but has been significantly rearranged and revised. Ideally, all sports activities would have the surface individually specified, but economic pressures dictate that in many installations a number of sports have to be played in the same spac
10、e and often on the same surface. For this reason, requirements for surfaces for multi-sports use are given in this Part of BS7044. The likelihood of injury is a complex function of the properties of the surface and the nature of the sport to be played. The relevant physical properties are stiffness,
11、 energy absorption, friction and roughness. Particularly for a multi-sports surface it is not possible to define a complete safety specification nor to specify absolute limits for all relevant properties which will be applicable to all sports. Repeated interaction between the ball and players footwe
12、ar and the surface will inevitably result in wear due to both abrasion and fatigue processes. In practice, these processes cannot be separated and it is not possible to reproduce precisely in the laboratory the complex service conditions. Again, in service, the surface may be subject to complex patt
13、erns of temperature, sunlight and water. It is not possible to reproduce these conditions precisely in the laboratory. Consequently, the methods for measuring durability and environmental resistance cannot be readily used to predict service life, but the requirements specified set minimum standards
14、which, if met, should result in satisfactory durability. WARNING. It is incumbent upon the owners of, or operators of, a sports facility to satisfy themselves as to the suitability of the surface from a safety aspect for the sports to be played. It is considered essential that this Part of BS7044 is
15、 read in conjunction with BS7044-1. While the tests are intended to assess the most important features of a product to be used as an artificial sports surface, they cannot remove the necessity for regular inspection and maintenance, which is essential for reliable operation. Product certification. U
16、sers of this Part of BS7044 are advised to consider the desirability of third party certification of product conformity with this British Standard based on testing and continuing surveillance, which may be coupled with assessment of a suppliers quality systems against the appropriate Part of BS5750.
17、 Enquiries as to the availability of third party certification schemes will be forwarded by BSI to the Association of Certification Bodies. If a third party certification scheme does not already exist, users should consider approaching an appropriate body from the list of Association members. A Brit
18、ish Standard 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 fron
19、t cover, an inside front cover, pages i and ii, pages1 to 6, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on theinside front cover.BS7044-4:1991 BSI 02-1999 1 1 Scope
20、 This Part of BS7044 specifies requirements for artificial surfaces for multi-sports use, i.e. surfaces for installation where a number of different sports will be played. The requirements apply to the complete surface, i.e.the top layers and the substrate. NOTE 1It should be noted that requirements
21、 for surfaces for a particular sport may render those surfaces incompatible with requirements for other sports. Advice on requirements for surfaces for an individual sport should be sought from the governing bodies of the sport in question. NOTE 2A recommended test schedule is given in Appendix A. N
22、OTE 3 The titles of the publications referred to in this standard are listed on the inside back cover. 2 Dimensions Each surface shall be laid with an overall slope in any direction no greater than1 in100. Any localized bumps or hollows shall be not greater than6mm on an indoor area and not greater
23、than10mm on an outdoor area when measured using a 3m straightedge, and not greater than3mm when using a300mm straightedge. NOTE 1A suitable method of measurement using a straightedge is described in BS8203. Deviation from the finished plane shall be not greater than 6mm at any point on an indoor are
24、a and shall be not greater than 25mm at any point on an outdoor area. NOTE 2 The surface should be dimensionally stable so that, in normal use, it should not lift or buckle through the actions of temperature and weather, or from the interaction with equipment or players. The thermal expansion of the
25、 surface should be such that, with the recommended method of fixing to the substrate, the surface does not lift or buckle over the temperature range 5 C to +40 C. For any class of artificial grass sports surface (seeBS 7044-1) the mean pile height measured before any sand infill shall not vary by mo
26、re than 15% of the mean height and the distribution of the pile over the surface shall be uniform. In cases of dispute the pile height shall be determined by measuring the overall thickness and the thickness of the backing by the method described inBS4051. NOTE 3 The area of surface will normally be
27、 at least the minimum area required by the rules of the sports to be played. Information may be obtained from the governing bodies of the sports in question. NOTE 4Pronounced surface patterns or artificial grass may not be suitable for some sports and, if in doubt, information should be sought from
28、the governing bodies of the sport in question. A rough surface on a rigid material will increase the risk of injury from cuts and grazes and may substantially reduce ball life through abrasion. 3 Performance All classes of surface shall comply withTable 1 to Table 5, as appropriate. 4 Essential info
29、rmation The following information shall be supplied by the manufacturer to the purchaser. NOTEThis information should also, as far as possible, be included in any test reports. a) The number and date of this British Standard, i.e.BS7044-4:1991 1) . b) The designation “NOT IMPACT ENERGY ABSORBING”, “
30、FLAMMABLE”, “LOW PERMEABILITY” (Class0 surfaces 2)only), where appropriate. c) The substrate(s) to which the test results relate, the depth of substrate, type of material including particle size and shape, and method of bonding, if any. d) The colour and reflectance of the surface as defined in BS48
31、00. e) Details of which types of paint and/or tape can be applied effectively and without damage to the surface or significantly affecting the playing characteristics, or other line marking methods available, e.g.inlaid or woven lines. f) The means and substances to be used to carry out regular main
32、tenance in the form of cleaning of the surface. g) The details of any other regular maintenance, e.g.resealing or topping up the level of sand and, where appropriate, the sealants that may be used. h) An assurance that the surface does not contain in its finished state any substance which is known t
33、o be toxic or carcinogenic when in contact with skin, and that no toxic or carcinogenic substance(s) will be released as a vapour or dust during normal use. i) The principal sports for which the surface is intended. 1) Marking BS 7044-4 on or in relation to a product represents a manufacturers decla
34、ration of conformity, i.e.a claim by or on behalf of the manufacturer that the product meets the requirements of the standard. The accuracy of the claim is therefore solely the responsibility of the person making the claim. Such a declaration is not to be confused with third party certification of c
35、onformity, which may also be desirable. 2) As defined in BS7044-1.BS7044-4:1991 2 BSI 02-1999 Table 1 Ball/surface interaction Table 2 Person/surface interaction Property Sports ball Performance Test method Rebound resilience (wetand dry a ) No difference at 5+0, 2C, 23 2 C and 40 2 C within the ran

37、1:1989 NOTESpin may be measured using method4 of BS7044-2.1:1989. a A wetting procedure is given inAppendix C. b The method for ball roll gives a direct measure of the distance a ball with a given velocity will roll, but requires a large test area and is affected by wind and surface irregularities.
38、A greater ball roll than15m may be found on some artificial sports surfaces and it should not be inferred that these are unsuitable, particularly for indoor ball games. No limits can be laid down for ball roll, other than for outdoor hockey, because of the range of sports which may be played and the
39、 variety of balls which may be used. c The method for velocity change measures the rate at which the surface slows the rolling ball and does not require a very large test area. No limits can be laid down for velocity change, other than for football, because of the range of sports played and variety
40、of balls used and the lack of available data.
