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.
