The standards existence alone will notnecessarily prevent injuries. Like other physical activities,trampoline use
6、involves the risk of injury, particularly if theequipment is used improperly. Similarly, the use of a trampo-line enclosure alone will not necessarily prevent all injuries.1.5 The values stated in inch-pound units are to be regardedas standard.

This opening, when closed according to themanufacturers instructions, shall be of sufficient strength anddurability to withstand, without tearing, deformation or failure,a direct impact of the loads at the point of the opening and 8 in.to the l
30、eft and to the right of the opening (outlined in 6.1,Performance Requirement Test #1) with no penetration of anyportion of the test load beyond the outer edges of the openingor any opening of the barrier itself. If the enclosure barrieropening is overlapped, the opening point is considered themidsec
31、tion of the overlap.6. Performance Requirements6.1 Barrier Impact and Enclosure Support Pole (Frame)Impact TestsPerformance Requirement Test #1 requires fourimpacts of the maximum specified user weight limit applied asa dynamic side load according to the following procedures.Two of the impacts are t
32、o be directed at a point on the barriermidway between the support poles (frame) at a height mid-distance between the top and bottom of the enclosure barrier.The other two impacts are to be applied against the enclosuresupport poles (frame) at a height mid-distance between the topand bottom of the en
33、closure barrier. The impacts against theenclosure barrier and barrier attachment system shall notproduce permanent deformation, tearing or breaking of anycomponent of the enclosure barrier and barrier attachmentsystem. The impacts against the enclosure support (frame)shall not produce permanent defo
34、rmation, tearing or breakingof any component of the enclosure support (frame) or thesupport (frame) attachment hardware.6.1.1 Procedure for Performance Requirement Test #1The load shall be of mass equal to the maximum specified userweight limit. It should be composed of a bag approximately 16in. (41
35、0 mm) in diameter by 36 in. (910 mm) tall, such as alarge duffel bag filled with loosely compacted material such assand. Alternating small bags of sand and wood chips can beused to fill the bag. The center of gravity of the duffel bagshould be at the mid-point (approximately 18 in. (460 mm)from the
36、bottom). The dynamic side load shall be applied in apendulum motion against the enclosure barrier at the specifiedpoints (see 6.1).6.1.1.1 Secure one side of the trampoline so that thetrampoline cannot be moved or cannot slide along the surfaceon which the trampoline rests.6.1.1.2 Suspend the bag (l
37、oad) on a chain so that thedistance to the top of the chain (pivot point) to the center ofmass of the bag is 120 in. (3.0 m).6.1.1.3 Position the bag (load) so that it hangs against theside of the enclosure barrier at a point midway between theenclosure support poles (frame) at a height mid-distance
38、between the top and bottom of the enclosure barrier. The pivotpoint of the pendulum created by the load and chain should bepositioned directly above the top of the enclosure barrier. Thecontact point of the bag (load) to the enclosure barrier shouldbe on the opposite side of the enclosure from the p
39、oint thatsecures the trampoline from movement.6.1.1.4 Pull the bag (load) back until the load support chainis at a 30 angle.6.1.1.5 Release the bag (load) into the enclosure barrier.6.1.1.6 Repeat the test in 6.1.1.1-6.1.1.5.6.1.1.7 Repeat the set up in 6.1.1.1 and 6.1.1.2 in prepara-tion for impact
40、 tests against the enclosure support poles (frame)at a height mid-distance between the top and bottom of thesupport pole. Position the bag (load) so that it hangs against theenclosure support pole (frame) on the inside of the enclosure.The pivot point of the pendulum created by the load and chainsho
41、uld be positioned directly above the top of the enclosuresupport pole (frame). The contact point of the bag (load) shouldbe on the opposite side of the enclosure from the secured pointestablished in 6.1.1.1.6.1.1.8 Pull the bag (load) back until the load support chainis at a 30 angle.6.1.1.9 Release
42、 the bag (load) into the enclosure supportpole (frame).6.1.1.10 Repeat the test in 6.1.1.6-6.1.1.9.NOTE 1The results should meet or exceed the guidelines set forth inPerformance Requirement Test #1.6.1.1.11 Repeat the set-up in 6.1.1.1 and 6.1.1.2 in prepa-ration for impact tests against the enclosu
43、re opening at a heightas close as possible to the mid-distance between the top andbottom of the opening. Position the bag (load) so that it hangsagainst the enclosure opening on the inside of the enclosure.The pivot point of the pendulum created by the load and chainshould be positioned directly abo

The contact point of the bag (load) should be on theopposite side of the enclosure from the secured point estab-lished in 6.1.1.1.6.1.1.12 Pull the bag (load) back until the load support chainis at a 30 angle.6.1.1.13 Release the bag (load) into the enclosure open
45、ing.6.1.1.14 Repeat the preparation for impact tests as estab-lished in 6.1.1.11, except the position of the bag (load) is 8 in.to the right, as measured from the inside of the enclosure, fromthe enclosure opening as established in 6.1.1.11.6.1.1.15 Repeat the test methods in 6.1.1.12 and 6.1.1.13.6
46、.1.1.16 Repeat the preparation for impact tests as estab-lished in 6.1.1.11, except the position of the bag (load) is 8 in.to the left, as measured from the inside of the enclosure, fromthe enclosure opening as established in 6.1.1.11.6.1.1.17 Repeat the test methods in 6.1.1.12 and 6.1.1.13.6.2 Per
47、formance Requirement Test #2 requires that, follow-ing assembly of the trampoline enclosure in accordance withthe instructions provided to the consumer, there shall be nosharp edges or points on any portion of the trampolineenclosure capable of inflicting a cut on a child during normaluse or reasona
48、bly foreseeable abuse. All points and edges onthe trampoline enclosure shall be tested for sharpness inaccordance with the federal technical requirements in 16 CFR1500.48 and CFR1500.49 referenced in 2.3.F22250836.3 Performance Requirement Test #3 requires that thereshall be no pinch, crush, or shea
49、r points caused by junctures oftwo components moving relative to one another, or at anopening present in the enclosure support (frame) attachmentsystem or the enclosure barrier attachment system while theenclosure system is in normal use. Pinch, crush, or shear pointsshall be deemed to be any point that allows a316 in. (5 mm)diameter neoprene rod to enter at one or more positions orentraps a12-in. (13-mm) diameter neoprene rod. Entrapmentshall mean that a force of more than 2 lbf (9 N) is required topull out the rod. The neoprene rods shall have a hardnessr
