5、 Marking 8Packaging and Package Marking 91.4 This specification does not purport to address all of thehazards that may be associated with trampolines or trampolineenclosures, or both. The standards existence alone will notnecessarily prevent injuries. Like other physical activities,trampoline use in
6、volves 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 standard doesnot purport to address all of the safety concerns, if any,associated with its use. It is the r

If the enclosure barrieropening is overlapped, the opening
31、point is considered themidsection 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 proced
32、ures.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 barrier.The other two impacts are to be applied against the enclosuresupport poles (frame) at a height mid-distance betwee
33、n the topand bottom of the enclosure 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)sha
34、ll not produce permanent deformation, tearing or breakingof any component of the enclosure support (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 permanentdef

(410 mm) in diameter by 36 in. (910 mm) tall, such as alarge duffel bag filled with loosely compacted material suc
36、h 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 bottom). The dynamic side load shall be applied in apendulum motion against the enclosure barrier at the specif

The pivotpoint of the p

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 ang

(If there are 2enclosure poles at the same distance fro

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
