Strap jo
18、ints shall be sewn by lock stitching. 3.1.4 Labeling. Labeling shall be in accordance with ANSI Z359.1. 3.1.4.1 Legibility. The legibility and attachment of required markings shall last for the life of the harness. When pressure sensitive labels are used, they shall be in accordance with the provisi
19、ons of UL 969. 3.1.4.2 General markings. The following shall be marked in English on the equipment in accordance with ANSI Z359.1: National Stock Number incorporated onto an existing label, part number and model designation, year of manufacture, manufacturers name and logo, capacity rating, standard
20、 number “Z359.1”, and warning to follow the manufacturers instructions included with the equipment at time of shipment from the manufacturer. 3.1.4.3 Specific markings. The harness shall be marked to identify the following: the fiber used in the material construction, the size of the harness, the fa
21、ll arrest attachment element(s), the purpose of any other attachment elements, and a caution to use the front mounted attachment element only for a maximum of two feet free fall distance. 3.1.4.4 General and specific instructions. General instructions shall be provided in accordance with ANSI Z359.1
22、. Specific instructions shall explain the maximum free fall distance permitted; all the markings with appropriate elaborations and explanations; and donning, fitting, adjustment, and use information including warnings against improper methods of assembly. 3.2 Performance requirements. 3.2.1 Dynamic
23、strength test. The dynamic strength test shall be conducted in accordance with ANSI Z359.1. 3.2.1.1 Drop test structure. The drop structure shall allow enough vertical and horizontal clearance for the test with no obstruction. The natural frequency of the drop test structure shall be 200 Hertz. The
24、maximum elastic deformation of the anchorage under 2250 lbf (10 kN) should be 0.04 inch. 3.2.1.2 Test torso. Test drop weight shall have a form of a human torso with dimensions in accordance with ANSI Z359.1. The torso shall be rigid, have hardwood surface, and weigh 2002 pounds (1001 kg). 3 Provide
25、d by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-59867 3.2.1.3 Test lanyard. The test lanyard shall be made from Type 302 stainless steel, 7 by 19 aircraft cable construction in accordance with MIL-DTL-83420. The cable diameter shall be 38 inch (9.5 mill
26、imeters) and lanyard eyes shall be formed by flemish eye splices and secured with swaged fittings. 3.2.1.4 Quick release mechanism. The test torso and harness ensemble shall be released from the drop height via remotely operated quick release mechanism which synchronously triggers the data recording
27、 device. The data for the entire history of fall arrest shall be captured. 3.2.1.5 Testing and evaluation. The test torso and harness assembly shall free fall from a height of 3.3 feet (1 meter) and 12 inches (305 millimeters) maximum lateral distance from the anchorage via quick release mechanism.
28、After the drop, the assembly shall be suspended for 5 minutes while connected to the fall arrest system from the dorsal ring of the harness. The harness shall endure the dynamic forces of the drop and suspension period without breaking. The angle between the torso vertical centerline and vertical sh
29、all be no more than 30 degrees after the torso comes to rest. This test shall be conducted twice, once feet-first and once head-first. A new harness may be used for each test. 3.2.2 Dynamic strength test (frontal attachment). The dynamic strength test (frontal attachment) shall be conducted and eval
30、uated the same way as the dynamic strength test, except that the test lanyard of the fall arrest system shall be connected to the frontal D-Ring of the harness. 3.2.3 Strength of d-rings, o-rings, and oval rings. The strength of this hardware shall be tested in accordance with ANSI Z359.1. A static
31、tensile test load of 5000 lbf (22.2 kN) shall be internally applied to the hardware for a minute. The hardware shall stay intact to pass the test. 3.2.4 Strength of buckles and adjusters. Oval rings used as adjusters or other adjusters shall be subjected to Tensile Testing of Buckles and Adjusters t
32、est in accordance with ANSI Z359.1. The specimen shall be exposed to a tensile static force of 4000 lbf (17.7 kN) for a minute. It shall take one minute or more for the test machine to bring up the test load to avoid dynamic effects. The specimen shall not break to pass the test. 3.2.5 Proof loading
33、 of d-rings and oval rings. A tensile load of 3600 lbf (16 kN) shall be brought up to the specimen in more than one second and maintained for at least two seconds in accordance with ANSI Z359.1. Inspection after testing shall not reveal any cracking, breaking, or permanent deformation visible to the
34、 unaided eye. 3.2.6 Tensile strength of straps. Straps shall not break under 6000 lbf (26.69 kN) test load when tested in accordance with ASTM D6775 Standard Test Method for Breaking Strength and Elongation of Textile Webbing, Tape and Braided Material. 3.2.7 Static strength of the full body harness
35、. The standard 2202 pounds (1001 kilograms) torso shaped and hardwood surfaced rigid test weight shall be properly fitted in the full body harness in accordance with ANSI Z359.1. The harness shall then be attached to the lower and upper jaws of the testing machine by the torso crotch ring and harnes
36、s dorsal D-ring, respectively. The location of the buckles and adjusters shall be marked before testing in order to measure slippage later. The load shall be increased up to 6000 lbf (26.69 kN) at a rate of 2 inches/min (51mm/min) and maintained for a minute. Harness shall hold the test torso during
37、 the test and no element should break. Adjustable connectors shall not slip more than 1 inch (25 millimeters). Buckle and eyelet type of construction shall not tear a distance greater than that to the adjacent eyelet. 3.2.8 Static strength testing of full body harness (front mounted attachment). The
38、 same test for static strength for the full body harness shall be used, except the load to the harness frontal D-ring shall be increased to only 3600 lbf (16 kN) in accordance with ANSI Z359.1. The same procedures to make a pass or fail decision shall be followed. 3.2.9 Corrosion resistance. All the
39、 hardware shall pass a 48 hours salt spray test in accordance with ASTM B117. There shall be no sign of corrosion or red rust formation when inspected by an unaided eye. 4.
