22、Significance and Use4.1 This guide is to be used to assist the playgroundowner/operator, specifier, designer, etc., in determining theproperties that can be considered with regard to the protectivesurfacing in the playground. It is the intent to outline therequirements associated with design, instal
23、lation, and mainte-nance of the surface. This is not a technical document andtechnical information must be found in the various standards.5. Background and Rationale5.1 Since 1986, ASTM has been involved in the ongoingdevelopment and publishing of a standard specification for theimpact attenuation o
24、f the surface systems installed under andaround playground equipment. This is the work of the F08.63subcommittee on playground surfaces. This subcommitteeconsists of a broad spectrum of members including testinglaboratory personnel, scientists, engineers, manufacturers,safety experts, and owner/oper
25、ators of playgrounds.5.2 In 1986, Subcommittee F08.63 was given the responsi-bility to respond to the need for a standard for the impact-attenuating surface under and around playground equipment.Specification F1292 was first published in 1991. Since then, thespecification has been revised five times
26、 in 93, 94, 95, 96,and 99.5.3 In 1998, the subcommittee published a provisionalstandard specification (PS 83) for determination of accessibil-ity for wheelchair access of surface systems under and aroundplayground equipment. The standard was elevated to a fullstandard (see Specification F1951) in 19
27、99.6. Factors to Consider in the Selection and Specificationof Surface Systems6.1 Types of MaterialEvery surface system is unique inmaterial, formulation, composition, and source of raw materi-als and should be tested to confirm conformance with theASTM specifications as identified within this guide
28、 (Specifi-cations F1292, F1951, and F2075).7. Impact Attenuation7.1 The initial work of Subcommittee F08.63 was especiallyimportant since injuries sustained from falls to the surface weredetermined to be 60 % of all playground injuries.7.2 There are two measurements considered in the guide.The first
29、 is the g-max and the second is the HIC or Head InjuryCriteria. It should be recognized that serious injuries (forexample, long bone injuries and so forth) might occur eventhough the playground surfacing system meets the require-ments of Specification F1292. Lower values of g-max and HICsignify bett
30、er performance for impact absorption.7.3 The g-maxThe g-max is the measurement of the peakdeceleration of an instrumented metal headform when itimpacts the surface. When the object falls from the same heightonto a hard surface such as concrete, the impact duration willbe very short and therefore the
31、 peak deceleration (g-max) willbe high, but an impact on a resilient surface that yields anddeforms with the force, results in a longer impact and a lowerpeak deceleration (g-max).7.4 Head Injury Criteria (HIC)A measure of impactseverity that considers the duration over which the most criticalsectio
32、n of the deceleration pulse persists as well as the peaklevel of the deceleration.7.5 Critical HeightThe maximum height from which theinstrumented metal headform, upon impact, yields either ag-max that does not exceed 200 gs or HIC exceeding 1000,when tested in accordance with the procedure describe
33、d inSpecification F1292. The United States Consumer ProductSafety Commission states that “critical heightthe fall heightbelow which a life-threatening head injury would not beexpected to occur.”7.5.1 The surfacing material used under and around aparticular piece of playground equipment should have a
34、 criticalheight value of at least the height of the highest designated playsurface on the equipment.7.5.2 The CPSC Handbook for Public Playground Safety(see 2.3), Specification F1487 for play structures, as well asother national standards (see Section 2), provide fall heights forvarious pieces of pl
35、ayground equipment.7.6 Testing:7.6.1 Laboratory Testing (Three Temperatures)Specification F1292 recognizes that children play in climateswith diverse temperature ranges. For this reason, the materialsthat are used under playground equipment are required to betested in a laboratory at the temperature
36、s of 30F, 72F, and120F (1C, 23C, and 49C) to determine the height fromwhich the g-max does not exceed 200 or the HIC does notexceed 1000. The determination of this height is the criticalheight. When selecting an appropriate playground surfacesystem, the owner, specifier, or purchaser, or a combinati
37、onF2223 102thereof, of the playground should ensure that the critical heightmeets or exceeds the fall height.7.6.2 Minimum Performance StandardsSpecificationF1292 states that the pass/fail measurements for the specifica-tion are minimums.7.6.3 Field TestingSpecification F1292 allows for theperforman
38、ce testing of the playground surface in the field. Boththe g-max must not exceed 200 and the HIC must not exceed1000 (the same as the laboratory test). The fall height isdetermined by the appropriate playground equipment standard(for example, in the United States, Specification F1487,inCanada, CSA Z
39、614), however, the purchaser may specify ahigher drop height consistent with the specification at the timeof purchase. The specification requires that the drops take placeat a minimum of three locations for each play structure orfunctionally linked play structures in a playground site andshall inclu
40、de those areas that may exhibit less than optimalimpact characteristics. These areas may be high traffic orcompressed areas as well as areas containing seams, partitions,corners and fasteners, or anchors. The equipment operator shallbe trained in the proper orientation of the test instrument by acom
41、petent agency.7.6.3.1 A failure for impact attenuation of the field test willbe where the average of the last two of three drops at the exactsame location and drop height using the procedure in thestandard from the drop height specified by the purchaser for thesurface produces a g-max greater than 2
42、00 or a HIC greaterthan 1000. These tests can be carried out at any ambienttemperature. If the surface fails, the guide requires the owner/operator of the playground to repair or replace the failedsurface with a surface that will comply with the standard ortake the applicable part of the playground
43、(play structure andsurface) out of service until the surface can be brought intocompliance.7.6.4 The guide allows for the surface material to be testedin a laboratory to simulate wet and frozen conditions.8. Wheelchair Work Measure for Accessible SurfacingSystems8.1 In 1996, it was determined that t
44、here was a need for aperformance standard to determine the suitability of surfacingfor persons with disabilities. The result was SpecificationF1951.8.2 Laboratory TestingThe tests for determining accessi-bility for surfacing materials are performed on a prepared testbed of the material being tested.
45、 Testing is performed with thesample temperature in the range of 40 to 100F. A rider,weighing 165 + 11 4.4 lb, propels a wheelchair in a straightline, as well as turning 90, on the sample surface. Five trialsare run for each test, with the high and low values discarded,and an average is taken from t
46、he remaining three. For loose fillsystems, the sample is prepared each time the test is performed.The work per foot required to navigate on the surface shall notexceed the work per foot required to navigate a 7.1 6 0.2 %grade on a hard, smooth surface. The owner/operator of theloose fill surface mat
47、erial that meets Specification F1951 mustunderstand that maintenance such as smoothing and filling ofdepressions as a result of traffic and active play will berequired.8.2.1 Minimum Performance StandardsSpecificationF1951 states that the pass/fail measurements for the standardare minimums.Arequireme
48、nt of Specification F1951 is that thesurface must also meet the requirements of SpecificationF1292.9. Criteria for Engineered Wood Fiber9.1 In 2001, Subcommittee F08.63 approved and ASTMsubsequently published a new specification, SpecificationF2075 that describes the technical requirements for engin
49、eeredwood fiber. There are a number of tests performed on thesubject material and the owner/operator should request testcertificates. This specification ensures the quality of product.9.2 Laboratory TestingThe testing for this guide is per-formed in the laboratory for particle size and distribution,heavy metals, and tramp metal, and at the manufacturingfacility.9.2.1 Sieve AnalysisTesting is done by passing the mate-rial through a specified number of sieves to determine % ofeach particle size in the sample of the engineered wood fibe
