What is the full form of ASTM?

The correct answer is C, which stands for the American Society for Testing and Materials. This organization, now known as ASTM International, is a globally recognized leader in the development and delivery of voluntary consensus standards for materials, products, systems, and services. It plays a crucial role in ensuring safety, quality, and performance through standardized testing methods and specifications.

The full name reflects the organization’s original purpose of developing test methods and standards for materials, helping industries ensure that products meet specific requirements and are safe for public use. The involvement of various stakeholders—ranging from industry professionals to regulatory bodies—allows ASTM to maintain high standards that are widely accepted in numerous sectors including construction, manufacturing, and environmental services.

While the other options describe plausible variations, they do not accurately represent the standardized title of this prominent organization, which emphasizes the focus on testing and materials crucial for product reliability and safety.
