ASTM D2000-18 includes the properties of vulcanized rubber material (natural rubber, reclaimed rubber, synthetic rubbers, alone or in combination) that are intended for automotive applications but not constrained to solely that capacity.
The vulcanization of rubber is a process of treating rubber to give it properties that make it more useful. Vulcanization can give rubber better elasticity, strength, and stability. These properties allow rubber to withstand different concerns such as temperature. Charles Goodyear was the inventor of vulcanization. The procedure is generally occurs when one treats rubber with sulfur, though Goodyear found that other additional components could aid in the process.
ASTM D2000-18 exists to explain its rubber products classification system and to use it more effectively. The system is built around the idea that different rubber materials can be designated based on their characteristics. These designations are based on classes and types. For example:
- Types relate to the resistance to heat aging.
- Classes relate to resistance to swelling oil.
From this information and more specific guidelines, one can get an explanation of the material.
The purpose of ASTM D2000-18 and its classification system is to help engineers with the selection of practical, commercially available materials. It is also used to aid in distinguishing these materials in a line call-out. ASTM D2000-18 indicates that a line call-out is a specification, which should contain the following: “the document’s names, the prefix letter M, the grade number, the material designation (type and class), and the hardness and tensile strength, followed by the appropriate suffix requirements.”
ASTM D2000-18 and its system of classification was created to keep up with a changing industry and provide values for future rubber materials without having to reorganize the entire structure of the system. These designations are important because they consent to the usage of different manufacturers without sacrificing the uniformity that might otherwise come with a less rigid system.
