ASTM D4066-94b

Standard Classification System for Nylon Injection and Extrusion Materials (PA)

SCOPE
1.1 This specification covers nylon materials suitable for injection molding and extrusion. Some of these compositions are also suitable for compression molding and application from solution.
1.2 The properties included in this specification are those required to identify the compositions covered. There may be other requirements necessary to identify particular characteristics important to specialized applications. These shall be agreed upon between the user and the supplier, by using the suffixes as given in Section 5.
1.3 The values stated in SI units are to be regarded as the standard.
1.4 The following safety hazards caveat pertains only to the test methods portion, Section 11, 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. A specific hazards statement is given in 11.2. ^REFERENCE:

Designation: D4066 – 94b
Standard Specification for
Nylon Injection and Extrusion Materials (PA)
This standard is issued under the fixed designation D4066; 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 materials used in the fabrication
of end items or parts. It is not intended for the selection of materials. Material selection should be
made by those having expertise in the plastics field after careful consideration of the design and the
performance required of the part, the environment to which it will be exposed, the fabrication process
to be employed, the inherent properties of the material other than those covered by this specification,
and the economics.
