What organization publishes specifications for many different petroleum products?

ASTM, or the American Society for Testing and Materials, is well-known for developing and publishing technical standards for a wide range of materials, products, systems, and services, including various petroleum products. These specifications play a crucial role in ensuring quality, safety, and performance across industries. ASTM standards are utilized internationally and are paramount in establishing consistent criteria for testing petroleum products, which ensures that these products meet the necessary safety and efficacy requirements.

While API (American Petroleum Institute), ISO (International Organization for Standardization), and SAE (Society of Automotive Engineers) also develop standards relevant to petroleum products and the broader industry, ASTM is specifically recognized for its comprehensive approach to testing and specification in diverse applications, including oil and fuels. This specialized focus on a wide variety of materials makes ASTM the primary organization referenced in this context for publishing specifications.
