Is the diaphragm pressure gauge on the gas supply pipeline of a natural gas boiler, with a pressure of 60 KPa, considered a pressure gauge that requires mandatory inspection?
According to the **Standard ‘Rules for the Implementation of Mandatory Product Certification’ (CNCA-C11-09:2014), the scope of mandatory inspection includes pressure gauges used in products under pressure and with volume. Based on the information you provided, the diaphragm gauge installed on the gas supply pipeline of the natural gas boiler is a gauge used to measure pressure within a system. A pressure value of 60 KPa is relatively low, so it may not fall under the category of gauges that require mandatory inspection; it is necessary to determine exactly what type of gauge it is. It is recommended that you contact the local relevant inspection authorities to inquire about the specific details. .
