DESCRIPTION

1.1 This specification covers five grades of aluminum-coated, steel wire strand, composed of a number of round, steel wires, with aluminum coatings, 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.

1.3 Minimum breaking strengths of strand for each grade are specified in Table 1.

(A) The utilities grade is used principally by communication and power and light industries.
(B) The last numbers in parentheses refer to elongation requirements specified in Section 9.

1.4 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.

1.5 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.
