Standard Classification System for and Basis of Specification for Polyamide Molding and Extrusion Materials (PA)
|Publication Date:||1 March 2017|
|ICS Code (Rubber and plastics products in general):||83.140.01|
This classification system covers polyamide materials suitable for molding and extrusion. Some of these compositions are also suitable for application from solution.
The properties included in this classification system are those required to identify the compositions covered. Other requirements necessary to identify particular characteristics important to specialized applications are to be specified by using suffixes as given in Section 5.
This classification system and subsequent line callout (specification) are intended to provide 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 can be made by those having expertise in the plastic 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 costs involved, and the inherent properties of the material other than those covered by this classification system.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
The following precautionary caveat pertains only to the test methods portion, Section 11, of this classification system. 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 requirements prior to use.
NOTE 1-This classification system is similar to ISO 1874-1 ⁄-2, although the technical content is significantly different
