8、5.1 The appropriate governing association shall specify themat(s)size(s).SeeAppendix X1 for listings of associations andtheir addresses.5.2 Test the mat,core,and cover combined for shockattenuation properties using Test Method F 355,Procedure A,with an impact velocity of 424 cm/s(167 in./s).NOTE1424
9、 cm/s is equivalent to a free fall drop of 91 cm(3 ft).Theimpact velocity is specified,rather than drop height,because of varyingdegrees of friction in the guide rails of the equipment.5.3 The maximum severity index shall be 350.5.4 Design the cover of the mat so there is a smooth playingsurface.5.5
10、 The playing surface normally shall be one piece.If morethan one section is used,securely fasten both sections togetherwith a stepoff of no greater than 1.5 mm(116in.).6.General Requirements6.1 With each mat,the manufacturer shall supply materialsclearly marked:“These are assembly,care,maintenance a
11、ndinstructional materials.Read carefully before assembling andusing this mat.”The package shall contain the following items:6.1.1 Assembly InstructionsUnless specified otherwise inthe rules of the organization governing the competition,placethe tumbling mats on a firm,level surface at least 1.8 m(6
12、ft)from walls,obstructions or protrusions.The minimum over-head clearance of 3.7 m(12 ft)is recommended.6.1.1.1 Use the mat in well-lighted areas.If artificial illu-mination is provided,it is recommended that such artificialillumination meet the standards for gymnasiums and fieldhouses in the Illumi
