ASTM A855-03 (2020) pdf free.Standard Specification for Zinc-5 % Aluminum-Mischmetal Alloy-Coated Steel WireStrand.
The approximate weight per unit length of strand andthe minimum breaking strength of the finished strand shall beas specified in Table 1.A test in which the breaking strength is below theminimum specified and which may have been caused by theslipping of the specimen in the jaws of the testing machine,bybreaking within the jaws or within 1 in.[25.4 mm] of the jaws,or by the improper socketing of a specimen shall be disregarded and another sample from the same coil or reel shall betested. Tests shall be made on lengths of strand that do notcontain wire joints or splices.
The elongation of the strand in 24 in. [610 mm] shall benot less than that specified in Table 3.
The elongation shall be determined as the percentincrease in separation between the jaws of the testing machinefrom the position after application of the initial load to theposition at the initial failure in the test specimen. The separation of the jaws of the testing machine shall be approximately2 ft when under an initial load equal to 10 % of the requiredminimum breaking strength of the strand. The elongationvalues shall be recorded only for specimens that break overl in. from the jaws of the testing machine.Additional samplesshall be taken from the same coil or reel when the previoustests are to be disregarded.
