What is the US equivalent of DIN?

The US equivalent of DIN is ASTM International (formerly known as the American Society for Testing and Materials). DIN, or Deutsches Institut für Normung, is the German national organization for standardization, while ASTM is an international standards organization based in the United States.

ASTM International develops and publishes voluntary technical standards for a wide range of materials, products, systems, and services. These standards cover various industries such as construction, materials, petroleum, metals, plastics, textiles, and many others. They are widely used in the United States and internationally to ensure product quality, safety, and compatibility.

It is worth noting that while DIN and ASTM have their respective standards, they are not always equivalent or directly interchangeable. When seeking the US equivalent of a specific DIN standard, it is necessary to consult with experts or refer to resources that provide cross-referencing between DIN and ASTM standards to find the most suitable counterpart.
