1、Designation: F381 16 An American National StandardStandard Safety Specification forComponents, Assembly, Use, and Labeling of ConsumerTrampolines1This standard is issued under the fixed designation F381; the number immediately following the designation indicates the year of originaladoption or, in t

2、he case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscriptepsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This safety specification covers the components, theassembly, and the use of consumer

3、 trampolines.1.2 This specification is delimited in its application totrampolines of (1) a minimum bed size of 3300 in.2(21 300cm2), (2) a minimum height of 20 in. (51 cm), (3) intended forthe purpose of continuous, vertical jumping activities and (4)intended for consumer use.1.3 This specification

4、is intended (1) to reduce the demon-strated hazards associated with the use of trampolines byconsumers; (2) for trampolines used in a home environment bya single user; and (3) not to apply to institutional trampolinesor trampolines intended for use on water. Trampolines thatadhere to this specificat

5、ion are not recommended for use bychildren under six years of age.1.4 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 This standard d

6、oes not purport to address all of thehazards associated with trampolines. The standards existencealone will not necessarily prevent injuries. Like other physicalactivities, trampoline use involves the risk of injury, particu-larly if the equipment is used improperly.1.6 This standard does not purpor

7、t to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.7 This specification includes the following se

45、nd assembled in accordancewith the manufacturers instructions. The drop test shall use theequipment and procedures described in 6.2.5 and 6.2.6.Asaresult of the test:6.2.1 The impactor shall not tear the cover or completelypenetrate the padding;6.2.2 Seams of the padding shall not separate;6.2.3 The

46、 pad attachments shall not separate from the pad orframe; and6.2.4 The padding shall continue to cover the frame,springs, and frame hardware when the impactor is removedfrom the surface of the padding.6.2.5 Drop Test Weight and Impactor ShapeThe dropweight will consist of a 23-kg (50-lb) mass with a

47、 woodenimpacting surface. See Fig. 2. The edges of the impact surfaceare radiused and the heel and toe of the surface are contouredas shown in Fig. 2.6.2.6 Drop Test ProcedureThe impactor shall be droppedin a guided free-fall to contact the surface of the padding. Thesurface of the impactor shall be

48、 flat and parallel (within 5) tothe surface of the padding on the initial contact with the pad.The impactor shall be dropped on the portion of the paddingcovering the springs. The impactor shall be centered to impactat a location midway between the inner edge of the frame railand the edge of the tra

49、mpoline bed. The impactor shall beraised to a height of 12 in. (tolerance -0/+5 in.) (305 mm-0/+13 mm) above the surface of the padding. The impactorFIG. 2 Drop-Test Impactor ShapeF381 164shall be dropped at a minimum of two times near each of thefollowing locations, consistent with the required spacing cen-tered between the springs:6.2.6.1 Midway between attachment points,6.2.6.2 Adjacent to an attachment point,6.2.6.3 At a pad seam, and6.2.6.4 Above a leg.6.2.7 After the first impact, the impactor shall be raised toits initial drop height.
