A reference standard specification uses requirements set by an accepted authority or test method.

• A. They require brand names
• B. They are based on performance alone
• C. They use reference standards such as ASTM, ANSI, UL
• D. They specify only installation methods

Answer: (C)

Reference standard specifications rely on requirements published by recognized authorities or their test methods. That means the spec directs compliance with criteria defined by standards organizations such as ASTM, ANSI, or UL, whose published tests and performance criteria are widely accepted and publicly available. By referencing these standards, the project uses objective, verifiable criteria rather than depending on a particular brand. It also goes beyond installation steps, since the standard often defines how a material or system should perform and how its performance will be tested under specified conditions. This approach ensures consistency, safety, and interoperability across projects, because it relies on established, independent criteria rather than brand names or purely installation-focused guidance.
