1.1 This specification covers six mechanical tests, one corrosion resistance test, and the minimum performance requirements for these tests. This specification applies to carbiners designed specifically for use by rescue personnel during both training exercises and actual rescue operations. This specification does not apply to recreational use carabiners.

1.2 Two different types of carbiners are defined in this specification, a heavy-duty rescue carabiner and a light-duty rescue carabiner.

1.3 The values stated in SI units are to be regarded as the standard.

1.4 Tests contained herein are destructive in nature. Carabiners subjected to any of these tests shall not be used in any way after testing except in evaluation results of such testing.

1.5 This specification does not imply approval of any method of use of rescue carabiners. In addition, the tests described are laboratory tests and do not duplicate field conditions. Furthermore, the test load values contained herein are not to be interpreted as the forces which a rescue carabiner may be subjected to, or may be expected to sustain, in actual field use.

1.6 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
