This specification covers six mechanical tests, one corrosion resistance test, and the minimum performance requirements for these tests. This specification applies to carabiners designed specifically for use by rescue personnel during both training exercises and actual rescue operations. Two different types of carabiners are defined, a heavy-duty rescue carabiner and a light-duty rescue carabiner. The mechanical tests are: gate function test, gate locking mechanism function load test, major axis gate closed function load test, major axis gate closed ultimate strength test, major axis gate open ultimate strength test, and minor axis gate closed ultimate strength test. Carabiners may disengage or eject parts from the test fixture. Use a safety screen and wear safety glasses while testing.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Significance and Use
5.1 Gate Function Load Test—This test verifies that the gate can be opened (with the gate locking mechanism in the unlocked position) and that the gate can not be opened (with the gate locking mechanism in the locked position) while loaded with Function Test Force #1 along the major axis.
5.2 Gate Locking Mechanism Function Load Test—This test verifies that the gate locking mechanism can be unlocked, after Function Test Force #2 has been applied along the major axis and released.
5.3 Major Axis Gate Closed Function Load Test—This test verifies that the gate functions as originally intended, after Function Test Force #3 has been applied and released.
5.4 Major Axis Gate Closed Ultimate Strength Test—This test is intended to show the ultimate strength of the carabiner in the major axis with the gate closed.
5.5 Major Axis Gate Open Ultimate Strength Test—This test is intended to show the ultimate strength of the carabiner in the major axis with the gate open.
5.6 Minor Axis Gate Closed Ultimate Strength Test—This test is intended to show the ultimate strength of the carabiner in the minor axis with the gate closed.
5.7 Corrosion Test—This test is intended to verify that the carabiner is produced from a corrosion-resistant material, or adequately covered with a protective coating.
1.1 This specification covers six mechanical tests, one corrosion resistance test, and the minimum performance requirements for these tests. This specification applies to carabiners 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 carabiners are defined in this specification, a heavy-duty rescue carabiner and a standard-duty rescue carabiner.
1.3 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 the results of such testing.
1.4 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.
1.5 Quality control is solely the responsibility of the manufacturer or purchaser, or both, and is not addressed by this specification.
1.6 The values stated in SI units are to be regarded as the standard.
1.7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
