If no detectable play is observed, what does this imply regarding the spec?

• A. No play detected is within spec.
• B. Play cannot be measured accurately.
• C. Steering system is defective.
• D. The measurement should be ignored.

Answer: (A)

Understanding tolerances and what “no detectable play” means in a spec is the key idea. When a spec sets a maximum allowable amount of play, observing zero detectable movement means the part’s clearance is within that limit. Zero play is still within the allowed range, so the condition is considered within spec. This indicates the component is within tolerance and not defective due to excessive looseness. It doesn’t suggest measurement cannot be made, nor does it imply the steering system is defective, and the result shouldn’t be ignored—the measurement is a compliant indication that the spec is met.
