What is the inspection cycle for ordinary pressure gauges (Class B)?
Thread Content
I am an engineer in the company’s safety and environmental protection department. There are pipes connected to the side of the air conditioners used in the company, and pressure gauges that serve no purpose in terms of safety protection are installed above those pipes; they should belong to the category of ordinary pressure gauges (Class B). I am currently urging the relevant departments to conduct inspections as soon as possible. However, at present only pressure gauges used for safety protection fall under the category of devices that require mandatory inspection; according to the calibration standards JJG52-1999, the inspection interval for such gauges is every six months. Other general pressure gauges that are not used for safety purposes do not fall under this category, and in principle they should be inspected once a year (this is based on experience alone, as there are no regulatory requirements to the contrary). Therefore, the relevant authorities stated that there is no mandatory requirement; the so-called annual inspection is merely a recommendation, and it is not necessary to comply with it. How can I solve this problem? Can I find relevant laws and regulations to help me complete my work?

Class B pressure gauges do not fall under the category of pressure gauges that require mandatory inspection; they are generally calibrated in conjunction with the maintenance cycle of the equipment, such as during major overhauls of the installation. This should be specified in the standards for the management of measuring instruments – please check those
If it does not fall within the scope of mandatory inspection, it is recommended to classify it as Category C. If the company has its own corporate standards or quality management manual, then those should be followed. The inspection period is set at every 3 to 5 years for inspection or replacement. By the way, is the pressure gauge on the air conditioner related to production? If it’s not a problem, don’t include it in the equipment register.
Class A pressure gauges are installed on pressure vessels. Class B pressure gauges are subject to internal calibration by the company, usually on a semi-annual basis. Those that do not involve production safety can be classified as Category C and do not require inspection.
Ordinary pressure gauges every 6 months, precision pressure gauges every 1 year
Check your company’s measurement management procedures; if they do not exist, urge the quality management department to establish them as soon as possible. **There are no strict requirements for Class B instruments, but in principle they should be inspected once a year. If the safety supervision department conducts an inspection, or if higher-level audit departments or the customer’s audit team come to conduct audits, then verification records and certificates of conformity must be provided.
You selfish poster, what’s the purpose of completing your work? Is it to help the company make money, or to help it save money? If neither, then you might as well not do any work at all – just live a comfortable life without doing anything, as that would be more beneficial for the company.
It’s just a pressure gauge; it isn’t involved in any automated control systems, and it’s not a standard measuring instrument either. No one keeps an eye on it all the time. If it breaks, it’s replaced; if it doesn’t break, it’s still used. There’s no need to calibrate it – it’s a waste of money. .
