\n Abstract <\/b><\/p>\n

This specification covers polymer precoated steel sheet for corrugated steel pipe (CSP) which is coated after metallic coating on continuous lines by coil coating (roller coating or laminating) processes. The metallic coating shall either be zinc, aluminum-zinc alloy, or zinc-aluminum-mischmetal alloy. Sheet for this purpose shall be furnished flat in coils, flat in cut lengths, or corrugated in cut lengths, all being protected by a mill-applied polymer coating on both sides. The polymer coating shall be classified by grade corresponding to the thickness on each side. Requirements for the cleaning process of the steel sheet and for the polymer coating are given. The test methods for the following polymer coating properties are detailed: adhesion, impact, thickness, holidays, abrasion resistance, imperviousness, freeze-thaw resistance, weatherability, and resistance to microbial attack.<\/p>\n

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. <\/i> <\/font><\/p>\n

1. Scope <\/b><\/p>\n

1.1 This specification covers polymer precoated steel sheet for corrugated steel pipe (CSP) which is coated after metallic coating on continuous lines by coil coating (roller coating or laminating) processes. The metallic coating is either zinc, 55 % aluminum-zinc alloy, or zinc-5 % aluminum-mischmetal alloy. Sheet for this purpose is furnished flat in coils, flat in cut lengths, or corrugated in cut lengths, all being protected by a mill-applied polymer coating on both sides.<\/p>\n

1.2 The values stated in either inch-pound units or SI units are to be regarded separately as the standard. Within the text, the SI units are shown in brackets. The values stated in each system are not equivalents; therefore, each system must be used independently of the other.<\/p>\n

1.3 The following precautionary caveat refers only to the test method portion, Section 9, of this specification: <\/span> 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 and health practices and determine the applicability of regulatory limitations prior to use. <\/span> <\/span><\/p>\n
