1. Scope
1.1 This specification covers requirements and test methods for the material, dimensions, and workmanship, and the prop- erties of extruded and cast sheet, plate, rod and tubular bar, excluding pipe and fittings, manufactured from nylon or monomers. 1.2 The properties included in this specification are those required for the compositions covered. Requirements neces- sary to identify particular characteristics important to special- ized applications are described by using the classification system given in Section 4. 1.3 This specification allows for the use of recycled plastics (as defined in Guide D7209). 1.4 The values stated in English units are regarded as standard. The values in parentheses are for information only. 1.5 The following precautionary caveat pertains only to the test method portions 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 ofthe user ofthis standard to establish appropriate safety, health, and environ- mental practices and determine the applicability ofregulatory limitations prior to use. N OTE 1—There is no known ISO equivalent to this standard. N OTE 2—This specification is intended to replace Federal Standard LP-410A and PS 50. 1.6 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 Definitions: 3.1.1 regrind (plastic), n—a product or scrap such as sprues, runners and edge trim that have been reclaimed by shredding and granulating for use in-house. 3.1.2 For definitions of other technical terms pertaining to plastics used in this specification, see Terminology D883 or Guide D7209. 3.2 Definitions ofTerms Specific to This Standard: 3.2.1 finished product (F), n—product that meets the dimen- sional criteria of Table 1, Table 2, Table 3, or Table 4 of this specification.3.2.2 monomer-cast nylon, n—nylon polymer prepared by polymerization of epsilon-caprolactam or lauryllactam mono- mer. 3.2.3 oversize product (O), n—product that meets only the designated dimensional criteria of Table 2 or Table 4. 3.2.4 plate, n—flat stock greater than 3 ⁄ 8 in. (9.5 mm). 3.2.5 recycled-plastic shape, n—a product made from up to 100 % post-consumer material. 3.2.6 rod, n—an extruded solid cylindrical shape with a minimum diameter of 1 ⁄ 16 in., or cast solid cylindrical shapes with a minimum diameter of 1 in. (25.4 mm). 3.2.7 sheet, n—flat stock less than and including 3 ⁄ 8 in. thickness. 3.2.8 tubular bar, n—extruded annular shapes with mini- mum inside diameter of 3 ⁄ 8 in. (9.5 mm) and minimum wall thickness of 1 ⁄ 16 in. (1.6 mm), or cast shapes with minimum inside diameter of 1 ⁄ 2 in. (12.7 mm), and minimum wall of 1 ⁄ 4 in. (6.4 mm). 3.2.9 unmodified virgin plastic shape, n—a product pro- duced from virgin plastic, as furnished by a manufacturer, with no additives or processing aids. 3.2.10 virgin-plastic shape, n—product that is produced from 100 % plastic resin that has not been subjected to subsequent melt processing.
4. Classification and Material
4.1 Product shape and size as defined in the applicable purchase order. 4.2 This specification covers product extruded and cast as listed in Table S-PA. Products included in the designations reference Classification System D6779 callouts where appli- cable. 4.2.1 The type of nylon extruded product is categorized by type, grade and class depending on resin and filler composi- tions as defined in Table S-PA. 4.2.2 Each type of nylon shape is categorized into one of several grades as follows: 4.2.2.1 Grade 1—General Purpose: (1) Extruded product made using virgin plastic plus up to 15 % maximum of an alternate virgin-nylon as a processing aid. (2) Monomer-cast nylon made from epsilon-caprolactam or lauryllactam monomer. 4.2.2.2 Grade 2—Recycled—This specification allows for the use of nylon plastic materials that are recycled, reconstituted, recycled-regrind, recovered, or preprocessed, or combination thereof, provided that the requirements as stated in this specification are met. It is the responsibility of the supplier and the buyer of recycled, reconstituted recycled- regrind, recovered, or reprocessed Nylon plastic materials, or combination thereof, to ensure compliance. (See Guide D7209.) (1) Extruded product made using any amount up to 100 % recycled nylon plastic. (2) Does not apply to cast product. 4.2.2.3 Grade 3—Unmodified Virgin: (1) Extruded product made using 100 % unmodified virgin plastic. (2) Does not apply to cast product.
