1、Designation: F1772 17Standard Specification forHarnesses for Rescue and Sport Activities1This standard is issued under the fixed designation F1772; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number

2、 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 intechnical rope rescue and climbing, mountaineering, caving,canyoneering, and other rope-b

3、ased sport activities. It estab-lishes requirements for the testing, performance, and markingof harnesses and for the instructions that are supplied withthem.1.2 This specification may contain test methods that do notentirely simulate real-life situations. The test methods aredesigned to give reprod

4、ucible results in a laboratory and,thereby, a means for product comparison.1.3 Three types of harnesses are covered by this specifica-tion: full body harnesses, sit harnesses, and chest harnesses.1.4 The values stated in SI units are to be regarded asstandard. No other units of measurement are inclu

5、ded in thisstandard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to

6、 use.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarrie

Harness Labeling and Information6.1 The following information shall be affixed durably tothe harness:6.1.1 The location(s) and method

18、of rope or lanyardattachments,6.1.2 The location(s) and method of rappel and belay deviceattachments,6.1.3 The method of properly using buckles and adjustingdevices,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 inf

19、ormation shall accompany the productthrough the point of sale:6.2.1 The weight of the 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 thatindicate the product is worn out,6.2.5 If the product is primarily mar

20、keted for climbing,mountaineering, or other sport activity; accompanying theproduct shall be a three-part statement designed to alertconsumers to the inherent risks in that targeted activity, and themost basic guidelines for use of the product. The warning shallread as follows:6.2.5.1 Failure to fol

21、low these warnings increases the risk ofinjury of death.6.2.5.2 You are responsible for your own actions anddecisions.6.2.5.3 Special knowledge and training are required to usethis product.7. Performance Requirements7.1 During each of the tests described in Section 12,noload-bearing part shall break

22、 completely. In addition, theharness shall not be released from the torso.7.2 The webbing in all buckles and adjusting devices shallslip no more than 20 mm.7.3 If there are multiple independent rope attachmentpoints, the tests shall be repeated for each rope attachmentpoint specified in the manufact

This tensile force shall be held for 1 6 0.25 min,and the tension then shall be completely released over amaximum of 1 min. The tensile force shall be reapplied

33、 andincreased to 10 + 0.30 kN as before and held for 3 6 0.25min before release.12.1.4 The harness shall pass or fail according to 7.1 and7.2.F1772 172NOTE 1All linear dimensions are in millimetres, 65 mm.NOTE 2The dimensions are those of a torso developed by the UIAA for testing harnesses.NOTE 3Wai
