IEC 62053-31:1998 pdf download – Electricity metering equipment (a.c.)-Particular requirements – Part 31: Pulse output devices for electro mechanical and electronic meters (two wires only).
This part of IEC 62053 is applicable to passive, two-wire, externally powered pulse output devices to be used in electrIcity meters as defined by the relevant standards of technical committee 13 (see normative references) as well as future standards for static VA-hour meters.
Such pulse output devices are used to transmit pulses, representing a finite energy quantity, to a receiver (e.g. a tariff device).

4.4 Electrical requirements
4.4.1 Interaction with the meter
In order to ascertain that the pulse output device has no adverse influence on the meter and the meter has no adverse influence on the pulse output device, the tests of the following clauses and subclauses shall be carried out and the requirements met, unless otherwise specified in this standard:
— clause 6 “Electrical requirements” and clause 8 Accuracy” of IEC 60145:
— clause 6 “Electrical requirements, clause 8 Accuracy. clause 9 Starting and running with no load” and clause 10 “Adlustment” of IEC 60521:
— subclauses 4.4 Electrical requirements” and 4.6 “Accuracy requirements” of IEC 60687, lEG 61036 and lEG 61268.
4.4.2 Power consumptIon
For static meters and electromechanIcal meters equipped with pulse output devices, the power consumption shall not exceed the values specified in table I of IEC 61899 for multi-function meters.
4.4.3 Influence of supply voltage
4.4.3.1 Voltage range
Refer to IEC 61036.
4.4.3.2 Voltage dips and short interruptions
Voltage dips and short interruptions shall not cause more than one pulse, When the voltage is restored the pulse output device shall not have suffered degradation of its characteristics.
For testing see 5.4.1.
4.4.4 Insulation
The pulse output device shall withstand the impulse voltage test and the ac. voltage test, as specified In 5.4.6 of IEC 61036
4.5 Electromagnetic compatibility (EUC)
4.5.1 Immunity to electromagnetic disturbance
The pulse output device shall be designed in such a way that conducted or radiated electromagnetic disturbance as well as electrostatic discharge do not damage or substantially influence the pulse output device or the meter in which it is included.
For testing see 5.5.1 to 5.5.4.
4.5.2 Suppression of radio interference
Meters equipped with pulse output devices shall not generate conducted or radiated noise which can interfere with other equipment.
For testing, see 5.5.5.
