UL-1565:2013 pdf free download – STANDARD FOR SAFETY Positioning Devices.
8.2 Unless otherwise noted, prior to any testing or further conditioning, all nonmetallic and composite devices shall be pre-conditioned by exposure to a constant temperature of 23 ±2°C (73 ±4°F) and 50 ±5 percent relative humidity for a time period as indicated in Table 1, Stabilization Time for Conditioning Samples.
8.3 Unless otherwise specified, the tests shall be carried out at an ambient temperature of 25 ±5°C (77
±9°F) and at a relative humidity between 40 and 60 percent.
8.4 An adhesive relied upon for securement of a positioning device shall be tested in accordance with the requirements in Annex A, Adhesives.
8.5 A positioning device and its integral or separate component, the purpose of which is to secure the device to a mounting surface (such as a beam flange, drop wire, rod, or the surface of a panel or building structure), shall comply with the requirements for that device and its component.
8.6 An integral or separate component of a positioning device described in 8.5, that is dependent on the thickness of the material to which it is to be mounted or the mounting orientation, shall comply with all applicable tests when the device is assembled to the minimum and the maximum thickness of each type of mounting surface and in each intended mounting orientation.
9 Mechanical strength requirements
9.1 The mechanical strength of a positioning device shall be determined through tests under static or increasing loads.
9.2 A positioning device as classified in 5.5 (a), (b), or (c) shall maintain 100 percent of the manufacturer’s declared mechanical strength for 1 minute when tested as specified in Clause 14, Mechanical Strength Test Method. The tests shall be conducted on specimens both in the pre-conditioned state and after exposure to each of the appropriate conditionings described in Clause 16, Environmental Conditioning.
9.3 A positioning device as classified in 5.5 (a), (b), or (c) that is intended to provide limited support for
non-flexible conduit or tubing, shall maintain three times the manufacturer’s rated mechanical strength
(load rating) for five minutes without slipping after taking an initial set when tested as specified in Clause
14, Mechanical Strength Test Method.
9.4 A positioning device as classified in 5.5 (a), (b), or (c) that has a manufacturer’s rated mechanical strength (load rating) “No load rating” in accordance with 5.3, is not required to be tested to Clause 14, Mechanical Strength Test Method.
9.5 A positioning device as classified in 5.5 (d) or (e), other than a wiring duct, after exposure to each of the appropriate conditionings described in Clause 16, Environmental Conditioning, shall retain at least 50 percent of the mean mechanical strength of the sample set as measured in the pre-conditioned state when tested as described in Clause 14, Mechanical Strength Test Method.
9.6 Positioning devices specified in 9.5 shall be tested to failure. The recorded mechanical strength at failure for each sample in the pre-conditioned state shall be at least the mechanical strength declared by the manufacturer (see 5.3).
9.7 Integral or separately provided mounting means for use with a positioning device shall provide for secure fastening to the surfaces for which they are intended. Compliance shall be determined by the appropriate tests in Clause 14, Mechanical Strength Test Method.
9.8 A wiring duct as classified in 5.5 (d) or (e) shall be tested in accordance with Clause 15, Mechanical Strength/Elevated Temperature Test — Wiring Ducts. The result of this test shall be no softening or yielding of the material as determined by handling immediately after conditioning. After cooling to room temperature, there shall be no shrinkage, warpage, or other distortion of the device resulting in the release of wiring material.
