The method of environmental test for analytical instrumentsLine frequency and voltage testSubject content and scope of application
This standard specifies the conditions and methods for power frequency and voltage test of analytical instruments (hereinafter referred to as instruments). GB11606.2--89
This standard is applicable to the evaluation of the adaptability of instruments to the operation when the power frequency and voltage change. It is also applicable to instruments with special requirements for power frequency and voltage.
2 Test conditions
2.1 The instrument is powered by the power grid, with a power frequency of 50±0.5Hz (or 60±0.5Hz) and a voltage of 220±22V (the waveform distortion factor is not greater than 0.05).
2.2 The adjustment of voltage and frequency must be continuous and smooth. 3: Test method
3.1 Connect the power cord of the instrument to a power supply with adjustable frequency and voltage. 3.2 The power supply voltage is 220, 198, 220, 242V for at least 15 minutes, and the instrument is tested. 3.3 The power supply frequency is 50, 49.5, 50, 50.5Hz (or 60, 59.5, 60, 60.5Hz) for at least 15 minutes, and the instrument is tested.
Approved by the Ministry of Machinery and Electronics Industry of the People's Republic of China on March 25, 1989 and implemented on March 1, 1990
