6. Description of content: This part of IEC: 62052-11 covers type tests for electricity 
metering equipment to indoor and outdoor application and applies to newly manufactured equipment designed to measure the electrical energy on 50 Hz or 60 Hz networks, with a 
voltage up to 600 V.  
This part of IEC 62053-11 applies only to ne wly manufactured electrotechnical watt-hour 
meters of accuracy classes 0.5, 1 and 2 for the measurement of alternating current 
electrical active energy in 50 Hz or 60 Hz networks and it applies to their type tests only. 
PS: IEC: 62052-11: It applies to electromechanical or static meters for indoor and outdoor 
application consisting of a measuring element and register (S) enclosed together in a 
meter case. It also applies to operation indicator (S) and test output (S). If the meter has 
a measuring element for more than one type of energy (multi-energy meter), or when other functional elements, such as maximum demand indicator, electronic tariff registers, time switches, ripple control receivers, data communication interfaces, etc. are enclosed in 
the meter case, then the relevant standards for these elements apply. 
It does not apply to: a) portable meters 
b) data interfaces to the register of the meter 
c) reference meters 
For rack-mounted meters, the mechanical properties are not covered in the standard. G/TBT/N/PAK/62
