This specification covers extruded and cast sheet, plate, rod and tubular bar manufactured from nylon or monomers. Requirements necessary to identify particular characteristics important to specialized applications may be described by using the given classification system. The use of recycled plastics is allowed in the specification. The materials shall be subject to tests to determine tensile strength at break, tensile modulus, dimensional stability, lengthwise camber and widthwise bow, squareness, flexural modulus, and Izod impact.

1.1 This specification covers requirements and test methods for the material, dimensions, and workmanship, and the properties 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 necessary to identify particular characteristics important to specialized 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 of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Note 1: There is no known ISO equivalent to this standard.

Note 2: This specification is intended to replace Federal Standard LP-410A and PS 50.
