DVGW G 5484 describes the OMS conformity assessment for unidirectional meters for electricity, gas, water and heat. To supplement this, the ZP 4400 certification programme sets out the surveillance requirements.
However, as not all types of OMS devices are covered by DVGW G 5484, it was decided to convert DVGW G 5484 into a standard and to include further device types.
As an interim solution until the standard is finalised, DVGW CERT GmbH has expanded its ZP 4400 certification programme and now offers OMS conformity assessment for all types of OMS devices.
Applications can be submitted with immediate effect.
