This specification covers zinc-coated flat steel tape in coils for use as interlocking armor and flat armor for electric cables. The zinc-coated tape is produced with three classes of zinc coating weight. The zinc-coated tape shall be furnished in coils of one continuous length, with not more than an average of one weld/50 lb [23 kg]. The tensile strength shall be determined on longitudinal specimens consisting of the full width of the tape when practical, or a straight specimen cut or sheared from the center of the tape. The elongation shall be determined as the permanent increase in length, after failure of a marked section of the tape specimen originally 10 in. in length. The tape shall be capable of being bent flat on itself, either lengthwise or crosswise, without indication of failure. During the visual inspection, 1 sample coil shall random be selected from every 10 coils in the first 100 coils of the lot and 1 sample coil shall random be selected for every additional 35 coils, but not less than 3 coils from the entire lot. The weight of coating shall be determined by the hydrochloric acid-antimony chloride method. The zinc coating shall remain adherent without flaking or spalling when the tape is subjected to a 180° bend over a mandrel of required diameter.
