What is the primary purpose of ASTM?

• A. To define weather zones.
• B. To define properties or test procedures for materials.
• C. To design roofs.
• D. To certify installers.

Answer: (B)

Standards created by ASTM define the properties that materials should have and the test methods used to verify those properties. This standardization lets you compare products reliably, ensures consistent quality, and supports safe, predictable performance across different manufacturers and applications. An ASTM standard might specify a material’s required properties (such as strength, durability, or chemical makeup) and the exact procedures for testing those properties, so everyone follows the same method and can determine if a material meets the agreed criteria. These standards can then be referenced in specifications, codes, or procurement documents to ensure compatibility and quality. They aren’t about designing roofs or certifying installers themselves, but about providing the agreed-upon language and methods that underpin those activities.
