1.3 Stanchions may be used with 3⁄8-in. (9.5-mm) galvanized close link chain or wire rope lifelines 9⁄16-in. (14-mm) top course, 7⁄16-in. (11-mm) lower courses.
1.4 This specification covers only the stanchions and does not cover requirements for the chain or wire rope lines to be supported by the stanchion.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6 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.
