33、closure Support Pole (Frame) Impact TestsPerformance Requirement Test #1 requires four impactsof the maximum specified user weight limit applied as a dynamic side load according to the following procedures. Two of theimpacts are to be directed at a point on the barrier midway between the support pol

34、es (frame) at a height mid-distance betweenthe top and bottom of the enclosure barrier. The other two impacts are to be applied against the enclosure support poles (frame)at a height mid-distance between the top and bottom of the enclosure barrier. The impacts against the enclosure barrier and barri

The impacts against the enclosure support (frame) shall not produce permanent deformation, tearing orbreaking of any component of the enclosure sup

36、port (frame) or the support (frame) attachment hardware. If the measured angleof an enclosure pole is greater than 10 from its original measured angle after the test, it shall be interpreted as a permanentdeformation.6.1.1 Procedure for Performance Requirement Test #1The load shall be of mass equal

37、to the maximum specified user weightlimit. It should be composed of a bag approximately 16 in. (410 mm) in diameter by 36 in. (910 mm) tall, such as a large duffelbag filled with loosely compacted material such as sand. Alternating small bags of sand and wood chips can be used to fill the bag.The ce

38、nter of gravity of the duffel bag should be at the mid-point (approximately 18 in. (460 mm) from the bottom). The dynamicside load shall be applied in a pendulum motion against the enclosure barrier at the specified points (see 6.1).6.1.1.1 Secure one side of the trampoline so that the trampoline ca

40、that it hangs against the side of the enclosure barrier at a point midway between the enclosuresupport poles (frame) at a height mid-distance between the top and bottom of the enclosure barrier.

The contact point of the bag(load) to the enclosure barrier should be on the opposite side of the enclosure from the point that secures the trampoline frommovement.(1) Measure and record the angle of the enclosure pole nearest the intended barrier impact point, at the midpoint between thetop of t

(If there are 2 enclosure poles at the same distance from the intended barrier impact point, select one asthe test subject). Two measurements at this midpoi

One measurement to be taken on the surface of theenclosure pole furthest from the center of the trampoline jump mat, and another measurement to be taken 90 around thecircumference of the enclosure pole from the first measurement.6.1.1.4 Pull the bag (load) back until the load

Position the bag (load) so that it hangs against the enclosuresupport pole (frame) on the inside of the enclosure. The pivot point of the pen
