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

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
