ASTM D5989-18

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D5989 − 14a D5989 − 18
Standard Specification for
Extruded and Monomer Cast Shapes Made from Nylon (PA)
This standard is issued under the fixed designation D5989; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
This specification is intended to be a means of calling out plastic products used in the fabrication
of end items or parts.
1. Scope*
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 safety, health, and healthenvironmental 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.
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.

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 applicable.
4.2.1 The type of nylon extruded product is categorized by type, grade and class depending on resin and filler compositions 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,
