Core samples should be delivered to the testing laboratory in a manner that provides for their protection during transport from jarring, rolling, or impact with any object.

• A. True
• B. Not Applicable
• C. False
• D. Not Stated

Answer: (A)

Protecting core samples during transport preserves their physical integrity so test results reflect the material as it actually exists. Core samples are often brittle and sensitive to handling; jarring, rolling, or impact can induce cracks, delamination, or movement of the binder–aggregate structure. Any damage or alteration from transport can change measured properties such as density, void content, and binder distribution, leading to unreliable results. Using protective packaging, rigid containers, proper cushioning, and secure placement minimizes movement and damage, ensuring the lab receives a representative specimen. That’s why the statement is true: protecting samples during transport is essential for accurate testing.
