Inspection cycle for pressure gauges
Thread Content
What is the typical inspection cycle for pressure gauges? According to JJG52-2013, depending on the operating environment and usage cycle, the general inspection interval should not exceed 6 months. Are those watches subject to mandatory inspection and need to be sent to a testing institute for inspection? I heard before that the inspection interval for pressure gauges is determined based on the properties of the medium involved; for example, those used with water can be inspected once a year, while those used with flammable or toxic substances need to be inspected every six months. Is there such a saying? Thank you
There’s no need to make it so complicated; all items should be sent for inspection every six months. For mandatory inspections, it is done in this way; for corporate self-inspections as well, the interval is half a year.
1. Aren’t instruments classified into categories A, B, C based on their specific uses? – The calibration interval for instruments should be determined according to their purpose. 2. Pressure gauges have those round, bulky designs that look ugly, just like hippos; since they’re not used in automatic control systems, it’s likely that you only bother to check them when you’re really bored, right? 3. In some locations, pressure gauges are installed; it’s better to replace them when they get damaged. Since they weren’t calibrated throughout their lifetime before they broke down, this actually helped save resources for all sectors of society. Don’t treat all measurement issues as matters related to weighing. For example, if you ask how many ounces or pounds of feces you produce in a day, and you weigh them in a basin and fill out a form to keep track of it, what value does that action have for **society, for your neighbors and family, for you personally, and for future generations? 4. When doing things, one should consider what the value is. Right?
5. As for pressure gauges, in some applications where they are used, the actual requirements regarding pressure measurement accuracy are far lower than the precision of the gauge itself at the time of manufacture. In this way, even if the accuracy of the pressure gauge deteriorates over time and it becomes significantly inaccurate, it can still meet the practical requirements. There are plenty of situations where low precision is sufficient; it’s so low that even if you search the whole world, you won’t find any manufacturers willing to produce and sell pressure gauges with such low precision. So one has no choice but to use those with much higher precision. {:3_51:}
I wonder if there are any regulatory requirements or specific notification requirements.
For items subject to mandatory inspection, they need to be tested every 6 months; for others, it is up to the enterprise to decide based on actual circumstances. For example, in the case of circulating water used solely for display purposes, testing is required only once at the time of first use, and there is no need to conduct further tests after it gets damaged and replaced. It would be useful to discuss this matter with external auditors and other relevant personnel if possible
