Questions and Answers

A: A. This choice drives UV control and cleanliness you can't hold in daylight and raises false calls on rough weld toes. B. Water washing in the field strips penetrant from tight toe cracks and needs controlled lighting you don't have. C. Post‑emulsifiable adds timing risk and operator error without fixing the lighting constraint. D. Visible dye with solvent removal aligns with daylight inspection and reduces process variability under turnaround pressure.

A: A. Extending dwell at low temperature increases diffusion blur without restoring capillary action. B. Visible systems are still viscosity‑limited and don't escape the physics. C. Sensitivity level doesn't correct penetration failure driven by temperature. D. The temperature band exists to control fluid behavior and probability of detection.

A: A. ASTM E165 governs method execution, not flaw acceptability. B. Swapping standards doesn't fix the absence of component‑specific limits. C. Sensitivity affects detection, not disposition of indications. D. Codes like ASME VIII define what indications are rejectable for that component.

A: A. Shorter dwell at lower temperature further reduces capillary fill. B. Dwell is temperature‑dependent through viscosity and surface tension. C. Excessive dwell drives background bleed‑out and false indications. D. Small increases are used cautiously and only when still within qualified conditions.
