X-Radiation Measurement Log (ANSI C37.85)

Inspection log for recording X-radiation readings at one meter during vacuum interrupter withstand testing, with pass/fail evaluation against allowable emission limits per ANSI C37.85 and applicable OSHA/NFPA safety practices.

Inspection Details

• Test date and time recorded
• Facility, test cell, or location identified
• Vacuum interrupter or equipment serial number recorded
• Test standard and procedure referenced
  Reference the applicable test procedure and standard, such as ANSI C37.85 and site SOP.

Test Setup and Safety Controls

• Measurement point established at one meter from the vacuum interrupter
  Confirm the X-radiation measurement was taken at the required one-meter distance.
• X-radiation meter calibrated and in date
  Verify the instrument calibration status is current and traceable.
• Test area controlled and unauthorized personnel excluded
  Confirm barriers, signage, or access controls were used to keep non-essential personnel out of the test area.
• Required PPE worn by test personnel
  Verify PPE appropriate to the electrical test environment was used.

X-Radiation Readings

• Background X-radiation reading at one meter
• Peak X-radiation reading during withstand test at one meter
• Allowable emission limit entered for comparison
• Peak reading within allowable limit
  Confirm the measured X-radiation did not exceed the applicable allowable limit.

Test Conditions and Observations

• Withstand test voltage recorded
• Test duration recorded
• Abnormal arcing, leakage, or equipment damage observed
  Record whether any abnormal conditions were observed during the test.
• Inspector comments and observed conditions

Deficiencies, Corrective Action, and Sign-off

• Deficiencies documented
  Indicate whether any deficiency or non-conformance was identified during the inspection.
• Corrective action recorded for any failed item
  Describe the corrective action, retest requirement, or escalation taken for any non-conformance.
• Inspector signature
