MID certification is a regulation used by the European Union to supervise and manage measuring instruments, 

and the measuring instruments within the scope of the regulation must pass the corresponding conformity 

assessment procedures before leaving the factory, in line with 2014/32/EU Directive, and marked with the 

MID certification mark and CE mark, in order to sell and use in the EU market.

MID regulations in the EU on April 30, 2004 for official notification, and October 30, 2006 mandatory 

implementation, on April 20, 2016 abolished the original Directive 2004/22/EC, the beginning of the 

implementation of the 2014/32/EU Directive, clarifying the new methodological standards of the legal 

system of measuring instruments, conformity assessment procedures and the implementation period 

of the Directive.

The MID Power meter is a meter that has passed the MID certification, which means that the manufacturer's 

meter products can be sold and used in EU member states. The manufacturer of the meter is responsible for 

the production and design of the MID kWh meter and is obliged to ensure that the MID meter sold on the 

EU market complies with the MID regulation. For MID meters placed on the EU market, not only does the 

meter itself need to comply with the MID regulations on the product's performance standards, but the 

manufacturer's capabilities also need to be verified on site.

The MID certification body needs to conduct on-site audits of the MID meter manufacturer's R & D design 

management capabilities, manufacturing capabilities, and product quality management capabilities every 

year to ensure Manufacturers continue to have the ability to develop and manufacture MID meters. 

Manufacturers can choose the designated certification body, and under the guidance of the designated 

certification body, the voluntary choice of certification mode. The designated organization is obliged to 

do the testing work of type approval, design approval, testing procedures and quality management system 

certification.
