1、Designation: F 381 06An American National StandardStandard Safety Specification forComponents, Assembly, Use, and Labeling of ConsumerTrampolines1This standard is issued under the fixed designation F 381; the number immediately following the designation indicates the year oforiginal adoption or, in
2、the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This safety specification covers the components, theassembly, and the use of consum
3、er 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 specificatio
4、n is intended to reduce the demon-strated hazards associated with the use of trampolines byconsumers. Trampolines primarily used by consumers are inhome environments. This specification is not intended to applyto institutional trampolines. Trampolines that adhere to thisspecification are not recomme
5、nded for use by children undersix years of age.1.4 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.1.5 This standard does not purport to address all of thehazards associated with trampolines. The standards existencealon
6、e 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 purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of t
7、he 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 sections andselected subsections.Title Section NumberScope 1Referenced Documents 2Terminology 3Included

29、20-in.2(129 cm2) round, flat headdropped from a distance of 2 ft (61 cm).6.2 Drop TestA drop test will be performed on the framepadding attached to a trampoline and assembled in accordancewith the manufacturers instructions. The drop test shall use theequipment and procedures described in 6.2.5 and
30、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 pad attachments shall not separate from the pad orframe; and6.2.4 The padding shall continue to cover the frame,springs, and frame hardwa
31、re 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 woodenimpacting surface. See Fig. 1. The edges of the impact surfaceare radiused and the heel and toe of the surface are contouredas show
32、n in Fig. 1.6.2.6 Drop Test ProcedureThe impactor shall be droppedin a guided free-fall to contact the surface of the padding. Thesurface of the impactor shall be flat and parallel (within 5) tothe surface of the padding on the initial contact with the pad.The impactor shall be dropped on the portio
33、n 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 trampoline 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. T
34、he impactorF381062shall 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, and6.2.6.3 At a pad seam.6.2.7 After the first impact
35、, the impactor shall be raised toits initial drop height. The results of the test with regard to padintegrity and coverage will be assessed. The padding shall notbe disturbed after removal of the impactor. The impactor isdropped a second time and the results recorded.6.3 Padding Attachment System Te
36、stsThe test describedin 6.3.1 is intended to measure the ability of the paddingattachment system to keep the frame pad in place whensubjected to typical forces imposed by users. The test in 6.3.1simulates a user climbing onto the trampoline by holding on tothe edge of the padding and climbing onto t
37、he bed of thetrampoline. The test is conducted on a fully assembled tram-poline with padding attached, according to the manufacturersinstructions.6.3.1 Padding Retention:6.3.1.1 Secure the fully assembled trampoline to the floor orbrace it to prevent movement of the trampoline as a result ofthe appl
38、ied forces.6.3.1.2 Place the trampoline pad pull fixture shown in Fig. 2with the fixture hooks facing down on the trampoline pad. Thefixture hook opening may be either of fixed thickness, adjust-able to the padding thickness, or V-shaped.6.3.1.3 Fixed thickness hooks shall be the thickness of thepad
39、ding 618 in. (63 mm). Adjustable fixture hooks shall beadjusted to the thickness of the pad. Adjustable hooks shall beadjusted to the thickness of the padding 618 in. (63 mm).V-shaped hooks shall not compress the padding thickness morethan18 in. (3 mm).6.3.1.4 Attach the fixture to the pad. Grasp th
40、e insidediameter edge of the frame pad as shown in Fig. 3.6.3.1.5 Using the outboard hook of the fixture, graduallyapply a horizontal force of 85 6 5 lbf (380 6 20 N) parallel tothe plane of the mat and radially outward from the center of thetrampoline. Apply the force at each of three locations sho
41、wn inFig. 3 such that: (1) a pad attachment tie down is centeredbetween the fixture arms, (2) the fixture is centered betweenFIG. 1 Drop-Test Impactor ShapeF381063adjacent pad attachment tie downs, and (3) a pad seam iscentered between the fixture arms6.3.1.6 Immediately release the force after it r
42、eaches 85 lbf(380 N). Repeat the force application two additional times atthe same location. After the third application of the force,release the force and remove the fixture without adjusting theposition of the pad.6.3.1.7 The padding attachment system passes this test ifafter removal of the force
43、and test fixture:(1) The padding continues to cover the trampolines frame,springs, and associated hardware,(2) The pad attachment is not broken or separated from thepad or frame, and(3) The pad cover (material or seams) is not torn.6.4 Drop Test for Trampoline Edge SurvivabilityWhere asystem other t
44、han frame padding is used for impact attenuation,a survivability drop test will be performed on the edge system.The trampoline shall be assembled in accordance with themanufacturers instructions. The drop test shall use the equip-ment and procedures described in 6.2 and 6.4.1. As a result ofthe test
45、 there shall be no evidence of permanent damage ordeformation to the edge system.6.4.1 Drop Test Procedure for Trampolines Where FramePadding Is Not RequiredThe impactor shall be dropped in aguided free-fall to contact the surface. The surface of theimpactor shall be flat and horizontal (within 5) o
46、n initialcontact with the surface. The impactor shall be dropped on anyportion of the edge system, such that the impactor footprintdoes not extend into space beyond the edge of the edge system.The impactor shall be raised to a height of 12 in. (tolerance60.5 in.) (305 mm (613 mm) above the surface.
47、Theimpactor shall be dropped a minimum of 2 times on eachchosen location. At least the following three locations shall betested:FIG. 2 Trampoline Pad Pull FixtureF3810646.4.1.1 Midway between the two suspension element attach-ment points, with the impactor long axis oriented perpendicularto the bed
48、edge;6.4.1.2 Centrally on a suspension element attachment point,with the impactor long axis oriented perpendicular to the bededge; and6.4.1.3 With the impactor edge aligned to any structuralstitch line.6.4.2 After the first impact, the impactor shall be raised toits initial drop height. The results
49、of the test with regard tosystem integrity will be assessed. The impactor guides shall notbe moved between impacts. The impactor shall be dropped asecond time and the results recorded.7.
