2、 last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers harnesses for human use in technical rope rescue and climbing, mountaineering, caving,canyo

3、neering, and other rope-based sport activities. It establishes requirements for the testing, performance, and marking ofharnesses and for the instructions that are supplied with them.1.2 This specification may contain test methods that do not entirely simulate real-life situations. The test methods

4、are designedto give reproducible results in a laboratory and, thereby, a means for product comparison.1.3 Three types of harnesses are covered by this specification: full body harnesses, sit harnesses, and chest harnesses.1.4 The values stated in SI units are to be regarded as standard.

14、nly to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Becauseit may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current ver

15、sionof the standard as published by ASTM is to be considered the official document.Copyright ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959. United States14. Summary of Specification4.1 Representative samples of harnesses shall be tested for minimum strength

16、.5. Significance and Use5.1 The strength of harnesses is one of the properties used to evaluate their suitability for a task.5.2 Marking and instructions aid in the selection and use of harnesses.5.3 Due to the diverse requirements of various rescue activities and environments, any of the included h

17、arness types may besuitable for rescue, including those marketed principally for climbing, and those with frontal and/or dorsal attachment points. Itis the responsibility of the AHJ or user to determine if a specific harness design is appropriate for a particular task. The exceptionis the sole use o

18、f a chest harness which must be used with a sit harness to be effective.6. Harness Labeling and Information6.1 The following information shall be affixed durably to the harness:6.1.1 The location(s) and method of rope or lanyard attachments,6.1.2 The location(s) and method of rappel and belay device

19、 attachments,6.1.3 The method of properly using buckles and adjusting devices,6.1.4 Manufacturers or distributors name and logo,6.1.5 The date of manufacture, and6.1.6 The size of the harness.6.2 The following information shall accompany the product through the point of sale:6.2.1 The weight of the

20、harness,6.2.2 Performance rating, if applicable,6.2.3 Care and maintenance of the product,6.2.4 Life of ProductInformation about attributes that indicate the product is worn out,6.2.5 If the product is primarily marketed for climbing, mountaineering, or other sport activity; accompanying the product

21、 shallbe a three-part statement designed to alert consumers to the inherent risks in that targeted activity, and the most basic guidelinesfor use of the product. The warning shall read as follows:6.2.5.1 Failure to follow these warnings increases the risk of injury of death.6.2.5.2 You are responsib

22、le for your own actions and decisions.6.2.5.3 Special knowledge and training are required to use this product.7. Performance Requirements7.1 During each of the tests described in Section 12, no load-bearing part shall break completely. In addition, the harness shallnot be released from the torso.7.2

23、 The webbing in all buckles and adjusting devices shall slip no more than 20 mm.7.3 If there are multiple independent rope attachment points, the tests shall be repeated for each rope attachment point specifiedin the manufacturers instructions. If multiple attachment points are designed to be employ

24、ed only in combination, as specified inmanufacturers instructions (such as side D-rings or shoulder D-rings), they shall be tested as a combination, with the combinationmeeting single-point performance standards.7.4 Each load-bearing attachment point on the harnesses shall be tested as described in

Sampling, Test Specimens, and Test Units9.1 Harness test specim

26、ens shall be new and in unused condition, selected randomly from a production lot of a given modelof harness. They shall conform in all respects to the manufacturers specifications for the model to be tested and shall be the propersize to fit the test torso. Two or more samples shall be tested annua

Calibration and Standardization10.1 Test equipment is to be in compliance with Practices E4 and other requirements specific to the equipment.F1772 172NOTE 1All linear dimensions are in millime

28、tres, 65 mm.NOTE 2The dimensions are those of a torso developed by the UIAA for testing harnesses.NOTE 3Waist circumference at X-X is 850 mm.FIG. 1 Outline of the TorsoF1772 17311. Conditioning11.1 Tests may be completed under ambient conditions. In cases of dispute, harness samples will be conditio

29、ned in accordancewith 11.2.11.2 The harness samples are first dried in an atmosphere with a relative humidity of less than 10 % for a period of 24 h. Thenthey are placed in an atmosphere of 50 6 5 % relative humidity, 20 6 2C for a period of 72 h. Tests may then be done outsidethe conditioning room,

30、 but the temperature shall be 23 6 5C. The tests shall begin within 5 min of removal from conditioningand be completed within 4 h.12. Harnesses12.1 Full Body Harnesses:12.1.1 The harness shall be put on a test torso and attached to the test machine in accordance with the manufacturersinstructions fo

31、r use.12.1.2 Upright Position of the Torso:12.1.2.1 The harness shall be loaded up to 800 6 10 N in the upright position of the torso. Under this load, adjust the torso andharness so that the attachment points are approximately symmetric about the vertical axis of the torso.12.1.2.2 With the torso i

32、n an upright position, a tensile force shall be applied to the lower ring, increasing to 16 + 0.30 kNover a period of 2 6 0.25 min. This tensile force shall be held for 1 6 0.25 min, and the tension then shall be completely releasedover a maximum of 1 min. The tensile force shall be reapplied and in

33、creased to 16 + 0.30 kN as before and held for 3 6 0.25min before release.12.1.3 Head-Down Position of the TorsoFollowing the same set-up as in 12.1.1 and 12.1.2.1, with the torso in a head-downposition, a tensile force shall be applied to the upper ring, increasing to 10 + 0.20 kN over a period of

34、2 6 0.25 min. This tensileforce shall be held for 1 6 0.25 min, and the tension then shall be completely released over a maximum of 1 min. The tensile forceshall be reapplied and increased to 10 + 0.30 kN as before and held for 3 6 0.25 min before release.12.1.4 The harness shall pass or fail accord

35、ing to 7.1 and 7.2.12.2 Sit Harnesses:12.2.1 Sit harnesses are to be tested in accordance with 12.1.2 and either 12.1.3 or 12.2.2.12.2.2 Buckle Test:12.2.2.1 The belt is attached between two non-rotating cylindrical pins of 30 6 10-mm diameter. See Fig. 2.12.2.2.2 Atensile force shall be applied inc

36、reasing gradually to 1 + 0.10 kN over a period of 1 6 0.25 min. Mark the webbingat the outer edge of the buckle. The tensile force shall be increased to 10 + 0.20 kN over a period of 2 6 0.25 min. This tensileforce shall be held for 3 6 0.25 min. Mark the webbing at the outer edge of the buckle. The
