1.1 This specification covers five grades of metallic-coated, steel wire strand, composed of a number of round, steel wires, with four weights of metallic coatings, and four types of metallic coatings, suitable for use as guys, messengers, span wires, and for similar purposes. 1.2 The five grades covered are as follows: 1.2.1 Utilities, 1.2.2 Common, 1.2.3 Siemens-Martin, 1.2.4 High-Strength, and 1.2.5 Extra High-Strength. 1.2.6 Minimum breaking strengths of strand for each grade are described in Section 7 . 1.3 The four weights of metallic coatings are: Class 1 and Classes A, B, and C. Minimum weights of metallic coatings are described in Section 10 . 1.4 The four types of metallic coatings are type 1, 2, 5, and 10 as defined in Section 3 . 1.5 Units— 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 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. 1.7 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.
