1.1This specification covers five grades of zinc-5 % aluminum-mischmetal (Zn-5 Al-MM) alloy-coated, steel wire strand, composed of a number of round, steel wires, with four weights of Zn-5 Al-MM alloy coatings, suitable for use as guys, messengers, span wires, and for similar purposes. The product is intended for applications requiring corrosion resistance and formability.

1.2The five grades covered are as follows:

1.2.1Utilities,

1.2.2Common,

1.2.3Siemens-Martin,

1.2.4High-strength, and

1.2.5Extra high-strength,

1.2.6Minimum breaking strengths of strand for each grade are described in Section 7.

1.3The four weights of coatings are: Class1 and Classes A, B, and C. Minimum weights of Zn-5 Al-MM alloy are described in Section 10.

1.4This specification is applicable to orders in either inch-pound units (as A855) or acceptable SI units (as A855M). Inch-pound units and SI units are not necessarily equivalent.

1.5This 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.

1.6This 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.
