2、r, in the case of revision, the year of 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 climbing harnesses for human use in the sports of ro
3、ck, ice, technical rope rescue and climbing,mountaineering, caving, canyoneering, and snow climbing. other rope-based sport activities. It establishes requirements for thetesting, performance, and marking of climbing harnesses and for the instructions that are supplied with them.1.2 This specificati

The test methods aredesigned to 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 har
5、nesses, and chest harnesses.1.4The values stated in SI units are to be regarded as the standard.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 This standard does not purport to address all of the safety concerns, if a

Summary of Specification4.1 Representative samples of climbing harnesses areshall be tested for minimum strength.5. Significance and Use5.1The strength of climbing harnesses is one of the properties used to evaluate
18、their suitability for climbing.5.2Marking and instructions aid in the selection and use of climbing harnesses.5.1 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 div
19、erse requirements of various rescue activities and environments, any of the included harness 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 specif
20、ic harness design is appropriate for a particular task. The exceptionis the sole use of a chest harness which must be used with a sit harness to be effective.6.
