Test Procedures7.1 Climb Net or Barrier Net:7.1.1 In Place Test Procedur
38、ePlace the foot probe (Fig.A1.1) in the opening, tapered-end first, with the plane of itsbase parallel to the plane of the opening; rotate the probe to itsmost adverse orientation (that is, the major axis of the base ofthe probe parallel to the major axis of the opening); apply aforce of 50 lb (23 k
39、g.) to the probe to attempt to pass it throughthe opening.Aclimb or barrier net passes the test if the openingdoes not allow the foot probe (Fig. A1.1) to be inserted sodeeply that the opening admits the base of the probe when it isrotated to any orientation about its own axis. A climb or barriernet
40、 fails the test if the opening allows full passage of the footprobe (Fig. A1.1).7.1.2 Climb nets and barrier nets shall meet this standardduring commission and throughout its life cycle.7.1.2.1 Testing is assumed to be conducted without guestson the nets. Testing can be conducted with or without the
41、weight of the person conducting the test, depending on accessto the testing locations.7.1.3 Backer nets shall not be used as part of the climbingsurface to bring the climbing net into compliance with testrequirements described in 7.1.1.7.2 Prototype Test for a Class 1 Barrier and No-holdNetting:7.2.
42、1 Class 1 barrier net or no-hold net shall be prototypetested. The test shall consist of two drops of a test as describedin 7.2.2-7.2.4. After the drops are completed, and the weight isremoved there shall be no broken strands fraying of the mesh,knots, nodes, or damaged bars. The net manufacturer sh

The test frame shall providea4by4-ft (1.22 by 1.22-m)inside opening appropriate for hanging net. The net
44、shall notcontact any surface during the test.7.2.3 When hung in accordance with 7.2.2, the net shall notsag more than 3 in. at its center before the first drop. The netedge shall be level. It is understood and acceptable for sag tobe present after the first or second drop.7.2.4 A 50-lb (23 kg) bag o
45、f sand, 24 6 2 in. (0.61 m 6 51mm) in diameter and no more than 12 in. (0.30 m) high, shallbe dropped into the net from a height of 8 ft (2.44 m) above thenet surface at center point of the net.7.3 Prototype Test Procedure for a Class 2 Barrier Net:7.3.1 Class 2 barrier net shall be prototype tested
46、. The testshall consist of two drops of a test as described in 7.3.2-7.3.4.After the drops are completed, and the weight is removed thereshall be no broken strands fraying of the mesh, knots, nodes, ordamaged bars. The net manufacturer shall provide certificationof this test and material compliance
47、per 5.2.7.3.2 AClass 2 barrier net shall be secured by each mesh, ina non-movable manner in a rigid frame 4 by 4 ft (1.22 by 1.22m). The test frame shall providea4by4-ft (1.22 by 1.22-m)inside opening appropriate for hanging the net. The net shallnot contact any surface during the test.7.3.3 When hu
48、ng in accordance with 7.3.2, the net shall notsag more than 3 in. at its center before the first drop. The netedge shall be level. It is understood and acceptable for sag tobe present after the first or second drop.7.3.4 A 250-lb (113 kg) bag of sand, 24 6 2 in. (0.61 m 651 mm) in diameter and no mo
49、re than 24 in. (0.61 m) high,shall be dropped into the net from a height of 8 ft (2.44 m)above the net surface at center point of the net.7.4 Prototype Test Procedure for Maximum Hole Size ofNo-Hold Netting:7.4.1 The hole entry resistance of the no-hold netting shallbe such that it will prevent the user(s) fingers or toes frombecoming inadvertently caught or entangled in the net. A meshopening shall not admit a 0.37-in. (9.5-mm) diameter rod withfull-radius tip, when tested in accordance with 7.4.2 and 7.4.3.The manufacturer shall provide certification of this test andmateria
