Which UCS code references impact testing exemption curves?

Which UCS code references impact testing exemption curves?

• A. UCS-65
• B. UCS-68
• C. UCS-67
• D. UCS-66

Answer: (D)

Impact testing exemptions are determined using specific curves published in the UCS section of the code. These curves show, for a given material type, thickness, and service temperature, whether an impact test can be waived. The reference that contains those exemption curves is UCS-66, which is why that option is the correct one. The other UCS numbers pertain to different provisions or curves and do not provide the impact-testing exemption curves.
