This opening, when closed according to themanufacturers instructions, shall be of sufficient

31、 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 Requirement Test #1) with no penetration of anyportion of the test load beyond the

32、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 Enclosure Support Pole (Frame)Impact TestsPerformance Requirement Test #1 requ

33、ires fourimpacts of the maximum specified user weight limit applied asa dynamic side load according to the following procedures.Two of the impacts are to 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

34、 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 theF2225 132enclosure barrier and barrier attachment system shall notproduce permanent deformation, tearing or

35、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 (frame) or thesupport (frame) attachment hardware. If the measured an

36、gle 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 maximum specified userweight limit. It should be composed of a bag app

37、roximately 16in. (410 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 i

38、n. (460 mm)from the 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.

39、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 theside of the enclosure barrier at a point midway between thee

40、nclosure 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. Thecontact point of the bag (load) to the enclosure barrier sh

41、ouldbe 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 enclosure pole and the uppermost pointof connection to the tramp

42、oline 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 should be recorded. One measurement to betaken on the surface of th

43、e 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 chainis at an angle that corresponds with the selected chain len
