- Scope
- This standard is applicable to the performance testing of industrial X-ray flaw detectors with rated power supply voltage of AC 220V, 380V or 220V/380 and frequency of 50Hz that are completely protected against electric shock. This standard specifies the test instruments, test procedures, result processing, etc. when conducting technical performance tests, safety reliability, and qualitative tests. General conditions for the test: a) Ambient temperature is 2℃~40℃; b) Relative air humidity is not greater than 85%; c) Power supply voltage fluctuation does not exceed ±10% of the rated power supply voltage; d) Atmospheric pressure is 83979Pa~106640OPa; e) The laboratory is well shielded from external ionizing radiation interference.
