Summary:

Enterprises can determine the verification cycle by A/B […]

Enterprises can determine the verification cycle by A/B/C according to the specific conditions of use.

A: Class A is mandatory verification, which is related to production safety and environmental monitoring. The verification period must be in accordance with the verification regulations, and can only be less than half a year; If the industrial and mining conditions are bad, the verification period must be shorter.

The following 3 types of Class 11 pressure gauges require mandatory verification:

1. The pressure gauge used for safety protection shall be compulsorily calibrated. The following 7 categories are included:

A. Measurement of boiler main cylinder and feed water pressure;

B. Pressure measurement of fixed air compressor air chamber and header;

c. Measurement of the generator, gas turbine oil pressure and locomotive pressure;

d. Measurement of pressure of medical autoclave and autoclave;

e. Pressure measurement with alarm device;

f. Measurement of the pressure of sealed pressurized vessels;

g. Measurement of the pressure of harmful, toxic and corrosive media. (For example Bourdon tube pressure gauge, electric remote transmission and electric contact pressure gauge).

2. The wind pressure gauge used for safety protection shall be compulsorily calibrated. That is, the measurement of roadway air pressure and wind speed in the mine. (such as my air pressure gauge, my anemometer).

3. The oxygen meter used for safety protection shall be compulsorily calibrated. The following 2 categories are included:

a. Measurement of oxygen monitoring pressure in the process of filling oxygen cylinders;

b. Measurement of oxygen pressure that is explosive and affects safety in the process.

4. Oxygen meters used for medical and health care shall be compulsorily calibrated. That is, the measurement of oxygen pressure on the buoy oxygen inhaler and oxygen supply device for oxygen delivery in hospitals

B: In principle, Class A should not exceed the provisions of the verification regulations.

C: Class A can determine the verification cycle according to the characteristics of the enterprise, but there should be a method to determine the verification cycle.
