ASTM B479-19 - 15.6.2019
 
1. Scope

1.1 This specification covers annealed aluminum and aluminum-alloy foil containing 98.00 % minimum aluminum and in thicknesses 0.00025 in. (0.0064 mm) to, but not including, 0.006 in. (0.15 mm). Alloys (see Note 1) covered by this specification include, but are not limited to 1100, 1145, 1235, 8011, 8079, and 8111, which conform to the requirements of 6.1 and Table 1. Unless otherwise specified by the purchaser, the alloy to be supplied shall be left to the discretion of the producer.

1.2 The foil is for use in packaging, which includes food handling and processing applications, requiring flexible barrier materials, and other general applications. The foil may be used as supplied or laminated to other materials, such as paper or plastic films.

1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A1.

1.4 The values stated in inch-pound units are to be regarded as the standard. The SI values in parentheses are for information only.

1.5 The following precautionary caveat pertains only to the test method portion of this specification: 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Note 1: Throughout this specification, use of the term alloy in the general sense includes aluminum as well as aluminum alloy.

Note 2: If the alloy is specified by the purchaser, its designation shall be in accordance with ANSI H35.1. The equivalent Unified Numbering System alloy designations are those shown in 1.1 preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E527.

1.6 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.
