A system reaches 500 microns and rises slowly to 650 after isolation, then stabilizes. What should the technician do?
- AOpen the system to air
- Use the decay acceptance test
- CIgnore isolation-valve leakage
- DCharge solely because 500 was reached
Why B is correct
A single pump reading does not prove dehydration or tightness. Decay behavior, test time, instrument location, and manufacturer criteria determine acceptance.
