Sampling by this practice covers procedures for obtaining representative samples, on which tests are to be performed to determine ____ with quality requirements of the specification under which the concrete is furnished.

• A. Compliance
• B. Durability
• C. Strength
• D. Consistency

Answer: (A)

The main idea is determining conformity to the specification. Sampling aims to obtain representative material so the tests can verify whether the concrete meets the quality requirements outlined in the specification under which it is furnished. Compliance means that all specified criteria are satisfied, which is the goal of testing against the contract. While durability, strength, and consistency are important properties that tests can measure, the purpose of this sampling practice is to confirm overall adherence to the specified quality requirements.
