ASTM D4976 PDF

The tests involved in this ASTM D specification for polyethylene plastics molding and extrusion materials are intended to provide information for identifying materials in accordance with the groups, classes, and grades covered. ASTM D covers polyethylene plastic materials that are classified into two groups in accordance with the molecular structure which may be branched or linear. TestResources provides equipment for materials testing thermosetting plastics. We have specimen preparation equipment, and universal testing machines for determination of mechanical properties of plastics. The other thermoplastic testing equipment listed bellow is for forming and testing thermoplastic molds. By means of our testing expertise and modular product design, we will help find the solution that is right for you.

More D The tests involved in this specification are intended to provide information for identifying materials in accordance with the groups, classes, and grades covered. Polyethylene plastic materials are classified into two groups in accordance with the molecular structure which may be branched or linear.

The specimens shall comply with the following requirements: flow rate; density; tensile stress at yield; nominal strain at break; secant flexural modulus; environmental stress-crack resistance; slow crack growth resistance; thermal stress crack resistance; permittivity; dissipation factor; volume resistivity; water immersion stability; flammability; and weatherability.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Scope 1. It is not the function of this specification to provide specific engineering data for design purposes.

This specification allows for the use of those ethylene plastic materials, provided that any specific requirements as governed by the producer and the end user are met.

Note 1—See Guide D for information and definitions related to recycled plastics. 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.
