If material comes out in lumps after testing, what should be done promptly?

• A. Retest promptly
• B. Document and proceed
• C. Ignore
• D. Repeat only if instructed

Answer: (A)

Lumps in a tested material mean the sample isn’t representative; a test result based on an uneven sample won’t reflect the true properties of the material. The correct action is to promptly retest with a well-mixed, representative sample to obtain reliable results that support proper decisions. Documenting and proceeding would risk using invalid data, ignoring the issue isn’t safe, and repeating only if told to can delay needed decisions—retaking the test right away ensures accuracy and keeps the process on track.
