Which standard is associated with the specifications for plastic?

The American Society for Testing and Materials (ASTM) plays a crucial role in developing and publishing standards for a wide range of materials, including plastics. ASTM International provides specifications, test methods, and guides that ensure the quality, safety, and effectiveness of plastic materials across various applications. This includes determining the physical and chemical properties of plastics, as well as performance requirements for different uses, which are essential for manufacturers and users alike.

While other organizations also establish standards, ASTM is specifically known for its comprehensive and widely recognized standards related to material specifications, including those for a variety of plastic products. ISO (International Organization for Standardization), ANSI (American National Standards Institute), and BSI (British Standards Institution) have their areas of focus but do not concentrate exclusively on plastics or have the same level of authority and recognition in this particular category.
