Factory calibration of combustible gas detection alarms
Thread Content
I have a newly purchased combustible gas detection alarm; the manufacturer provided a certificate of factory calibration. Do I still need to take it to a calibration institution for further testing?
The inspection carried out by the manufacturer does not equate to an inspection by a statutory certification body; moreover, general measuring instruments are required to be inspected upon entering the factory, so such inspection is necessary
Our company conducts tests before putting products into use
The quality supervision bureau can conduct on-site inspections~~~
Before putting it into use, we generally have it calibrated by the manufacturer; after use, it is taken to a metrology institution for calibration at the prescribed intervals
The factory certificate of conformity cannot replace the calibration certificate.
I really haven’t tested this. This year, my workplace also purchased a portable combustible gas detector, and we just use it directly
It needs to be recalibrated at a metrology institution!
After purchasing them, we need to test them before using them.
The manufacturer’s inspection must result in an inspection report; if one does not conduct the inspection themselves, what is required is an inspection report.
