FM T-238 details are associated with which of the following?

• A. The color coding of density results
• B. The weather conditions for tests
• C. The designation number for the nuclear density test
• D. The equipment calibration procedure

Answer: (C)

FM T-238 centers on how nuclear density tests are identified and recorded. The designation number is the unique identifier assigned to each test, so every result can be traced to a specific location, lift, or material and linked to the project records. This designation ensures proper QA/QC, traceability, and consistency in reporting density results. Elements like color coding of results, weather conditions for testing, or the calibration procedure are governed by other sections and forms, not by this designation.
