ASTM D4066-13 pdf free download.Standard Classification System for Nylon Injection and Extrusion Materials (PA).
1.1 This classification system covers nylon materials suitable for injection molding and extrusion. Some of these compositions are also suitable for compression molding and application from solution.
I .2 The properties included in this classification system are those required to identify the compositions covered. There may be other requirements necessary to identify particular characteristics important to specialized applications. These may he specified by using the suffixes as given in Section 5.
1 .3 This classification system and subsequent line call-out (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 should he made by those having expertise in the plastic held 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.
1.4 The values stated in SI units are to be regarded as the standard.
11. Test Methods
11.1 Determine the properties enumerated in this classification system by means of the test methods referenced in Section
11.1.1The number of tests shall be consistent with the requirements of Section 8.18.2 and 12.4.
12. Inspection and Certification
12.1 Inspection and certification of the material supplied with reference to a specification based on this classification system shall be for conformance to the requirements specified herein.
12.2 Lot-acceptance inspection shall be the basis on which acceptance or rejection of the lot is made. The lot-acceptance inspection shall consist of the tests listed as they apply:
(1) Relative viscosity, or viscosity number, or both,
(2) Moisture content,
(3) Reinforcement content,
(4) Carbon black content (weather-stabilized materials), and
(5) Heat stabilizer content (heat-stabilized materials, supplier’s test showing positive presence).
12.3 Periodic-check inspection with reference to a specific based upon this classification system shall consist of the tests specified for all requirements of the material under this classification system. Inspection frequency shall be adequate to ensure the material is certifiable in accordance with 12.4.
12.4 Certification shall be that the material was manufactured by a process in statistical control, sampled, tested, and inspected in accordance with this classification system and that the average values for the lot meet the requirements of the specification (line callout).
12.5 A report of the test results shall be furnished when requested. The report shall consist of results of the lot- acceptance inspection for the shipment and the results of the most recent periodic-check inspection.
13. Packing, Packaging, and Marking
13.1 The provisions of Practice D3892 apply to packaging, packing, and marking of containers for plastic materials.
