This opening, wh
32、en 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 left and to the right of the opening (outlined in 6.1,Performance Require
33、ment 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 themidsection of the overlap.6. Performance Requirements6.1 Barrier Impact and En
34、closure Support Pole (Frame)Impact TestsPerformance Requirement Test #1 requires fourimpacts of the maximum specified user weight applied as adynamic side load according to the following procedures. Twoof the impacts are to be directed at a point on the barrierF2225 152midway between the support pol
35、es (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 enclosure barrier. The impacts against theenclosure barrier and barrier
36、 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 deformation, tearing or breakingof any component of the enclosure support
37、 (frame) or thesupport (frame) attachment hardware. If the measured angle ofan enclosure pole is greater than 10 from its original measuredangle after the test, it shall be interpreted as a permanentdeformation.6.1.1 Procedure for Performance Requirement Test #1Theload shall be of mass equal to the
38、maximum specified userweight. It should be composed of a bag approximately 16 in.(410 mm) in diameter by 36 in. (910 mm) tall, such as a largeduffel bag filled with loosely compacted material such as sand.Alternating small bags of sand and wood chips can be used tofill the bag. The center of gravity
39、 of the duffel bag should be atthe mid-point (approximately 18 in. (460 mm) from thebottom). The dynamic side load shall be applied in a pendulummotion against the enclosure barrier at the specified points (see6.1).6.1.1.1 Secure one side of the trampoline so that thetrampoline cannot be moved or ca
40、nnot slide along the surfaceon which the trampoline rests.6.1.1.2 Suspend the bag (load) on a chain so that thedistance to the top of the chain (pivot point) to the center ofmass of the bag corresponds to one of the lengths specified inTable 1.6.1.1.3 Position the bag (load) so that it hangs against
41、 theside of the enclosure barrier at a point midway between theenclosure support poles (frame) at a height mid-distancebetween 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
42、. Thecontact point of the bag (load) to the enclosure barrier shouldbe on the opposite side of the enclosure from the point thatsecures the trampoline from movement.(1) Measure and record the angle of the enclosure polenearest the intended barrier impact point, at the midpointbetween the top of the
43、enclosure pole and the uppermost pointof connection to the trampoline frame with an angle finderdesigned for use on tubular/round surfaces. (If there are 2enclosure poles at the same distance from the intended barrierimpact point, select one as the test subject). Two measurementsat this midpoint sho
44、uld be recorded. One measurement to betaken on the surface of the enclosure pole furthest from thecenter of the trampoline jump mat, and another measurement tobe taken 90 around the circumference of the enclosure polefrom the first measurement.6.1.1.4 Pull the bag (load) back until the load support
45、chainis at an angle that corresponds with the selected chain lengthdistance in Table 1.6.1.1.5 Release the bag (load) into the enclosure barrier.FIG. 1 Requirements for Connecting DevicesTABLE 1 Length to Center of Mass and AnglePendulum Length toCenter of the Massof Bag (feet)Pendulum Length toCent

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 chai
48、nshould 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.(1) Measure and record the angle of the enclosure pole tobe impacted at the midpoint betw
49、een the top of the enclosurepole and the uppermost point of connection to the trampolineframe with an angle finder designed for use on tubular/roundsurfaces. Two measurements at this midpoint should be re-corded. One measurement to be taken on the surface of theenclosure pole furthest from the center of the trampoline jumpmat, and another measurement to be taken 90 around thecircumference of the enclosure pole from the first measure-ment.6.1.1.8 Pull the bag (load) back until the load support chainis at an angle that corresponds with the selected chain le
