Allframe and leg assemblies shall be joined or fastened together so that it requires either two distinct motions to separate those partsor tools to remove fasteners, to avoid unintentional separation.5.2.2 The

32、frame padding shall be of a color which contrasts with the color of the trampoline bed.5.2.3 The suspension system shall be designed so as to protect the performer from injury due to contact with the sharp ends ofthe trampoline springs.5.3 Performance Requirements:5.3.1 The frame padding, where requ

33、ired, shall be designed to remain securely attached to the frame when tested to therequirements of 6.2 and 6.3. All tests shall be conducted at ambient temperatures (nominally 68 6 5F (20 6 3C).5.3.2 Materials used in any pad cover, frame padding, cover attachments, tie down(s), and pad seams normal

34、ly exposed tosunlight shall be made from ultraviolet (UV) resistant materials and meet the performance requirements of 6.6.5.3.3 Material used in the trampoline mat shall meet the requirements specified in Practice F2774.5.3.4 Except for necessary seams, the frame padding, where required, shall cove

35、r the entire top surface of the frame and be wideenough to completely cover the entire top surface of the suspension system and frame when subjected to the tests specified in 6.2.5.3.5 Height of the bed from the ground or floor shall be sufficient to prevent the bed from contacting the ground or flo

36、or whilebouncing when tested to the requirements of 6.7.5.3.5 All information, instructions, and warnings shall be provided in English in addition to any other formats used, for example,graphical, video, multilingual, etc.5.3.6 When installed in accordance with the manufacturers instructions, fasten

37、ers, lock washers, self-locking nuts, or otherlocking means shall be provided for all nuts and bolts to protect them from unintentional loosening; self-locking nuts must fullyengage with the bolt. Hardware in moving joints shall also be secured against unintentional loosening.Any other fastening sys

38、temsshall comply with the requirement that effective locking requires two separate and distinct motions for release.5.3.7 There shall be no accessible sharp points or edges on fasteners when tested in accordance with 16 CFR 1500.48 and 16CFR 1500.49.5.3.8 Bolt ends projecting beyond the face of the

39、nut shall be free of burrs, sharp points, and sharp edges when tested inaccordance with 16 CFR 1500.48 and 16 CFR 1500.49.An accessible bolt end shall not extend more than the diameter of the boltbeyond the face of a nut when the nut is tightened to a torque between 20 and 25 lbf-in (2.3 to 2.8 N-m)

40、.F381 1535.3.9 If the exposed bolt end is not free of burrs, sharp points, or sharp edges, or a combination thereof, then the threaded endsof bolts may be covered by smooth, tight-fitting caps that shall resist a torque of 4 lbf-in (0.45 N-m) and a tensile force of 15 lbf(67 N) without loosening.5.3

41、.10 All fasteners shall be corrosion resistant to a level where no rust is evident after a 24-h salt spray test to Practice B117.5.3.11 No welds shall be made to any steel frame or accessory component with a thickness of less than 0.059 in. (1.5 mm).5.3.12 No “saddle” welds shall be made to any stee

42、l frame or accessory component with a thickness of less than 0.071 in. (1.8mm). An example of a saddle-welded tee fitting is shown in Fig. 1.5.3.13 All welded joints shall be rendered corrosion resistant to a level where no rust is evident after a 24-h salt spray test toPractice B117.5.3.14 No compo

43、nent shall be capable of presenting a protrusion hazard during foreseeable use.NOTE 1Test requirements that define a protrusion are in Specification F1487, Subsection 6.3.5.3.15 There shall be no accessible burrs, sharp points, or sharp edges on tubing when tested in accordance with 16 CFR1500.48 an

44、d 16 CFR 1500.49. End caps or plugs that cannot be removed without the use of tools on tubing may be used to meetthis requirement.6. Performance Requirements6.1 Shock AttenuationWhere padding is required, the shock-attenuating material used in the frame padding, as measured toinclude the frame and a

45、 minimum of 2 in. from the inside edge of the frame, shall limit the severity index to less than 450, whenthe same thickness as used in the frame padding is tested in accordance with Test Method F355 using a 20-lb (9-kg), 20-in.2(129-cm2) round, flat head dropped from a distance of 2 ft (61 cm).6.1.

46、1 Where padding is not required, the shock attenuating properties of any part of the trampoline edge shall limit the severityindex to less than 450, when tested on a fully assembled trampoline in accordance with Test Method F355 using a 20-lb (9-kg),20-in.2 (129 cm2) round, flat head dropped from a

47、distance of 2 ft (61 cm).6.2 Drop TestA drop test will be performed on the frame padding attached to a trampoline and assembled in accordance withthe manufacturers instructions. The drop test shall use the equipment and procedures described in 6.2.5 and 6.2.6. As a result ofthe test:6.2.1 The impact

48、or shall not tear the cover or completely penetrate the padding;6.2.2 Seams of the padding shall not separate;6.2.3 The pad attachments shall not separate from the pad or frame; and6.2.4 The padding shall continue to cover the frame, springs, and frame hardware when the impactor is removed from thes

49、urface of the padding.FIG. 1 Saddle Welded Tee FittingF381 1546.2.5 Drop Test Weight and Impactor ShapeThe drop weight will consist of a 23-kg (50-lb) mass with a wooden impactingsurface. See Fig. 2. The edges of the impact surface are radiused and the heel and toe of the surface are contoured as shown inFig. 2.6.2.6 Drop Test ProcedureThe impactor shall be dropped in a guided free-fall to contact the surface of the padding. Thesurface of the impactor shall be flat and parallel (within 5) to the surface of the padding on the initial contact
