BS EN 62053-31-1999 PDF

Full title and description

STB BS EN 62053-31:1999 — Electricity metering equipment (a.c.) — Particular requirements — Part 31: Pulse output devices for electromechanical and electronic meters (two wires only). This British-adopted EN specifies requirements for passive, externally powered two‑wire pulse output devices fitted to or associated with electricity meters to transmit energy pulses (for example to tariff or remote reading equipment).

Abstract

This part of the 62053 series defines electrical, mechanical and performance requirements, plus tests and marking for passive two‑wire pulse output devices used with electromechanical and electronic alternating‑current electricity meters. It covers the pulse transmission function (pulse shape, timing and electrical characteristics), environmental and durability conditions, and conformity/testing provisions.

General information

• Status: Published as BS EN (national adoption of EN 62053-31:1999); the underlying IEC publication has later national actions and has been superseded in some jurisdictions — see FAQ for current status.
• Publication date: BS EN adoption published 15 January 1999 (EN adoption dates vary by country, e.g. national publications in 1999).
• Publisher: British Standards Institution (BSI) as BS EN; original text derived from IEC/EN series (IEC 62053‑31 / EN 62053‑31).
• ICS / categories: Measurement of electrical quantities; electricity supply systems — ICS codes typically 17.220.20 and 91.140.50.
• Edition / version: Edition 1 (IEC 62053‑31:1998 / EN adoption 1999).
• Number of pages: National published versions vary (BS listing shows ~18 pages; some national editions list other page counts due to national forewords).

Scope

The standard applies to passive, two‑wire, externally powered pulse output devices intended for use with alternating‑current electricity meters (electromechanical and electronic). It sets requirements for the electrical interface and pulse generation used to represent quantities of energy, including pulse rate, amplitude and timing, connection and insulation, environmental and mechanical durability, testing procedures and markings. It does not cover other types of meter communications (for example multi‑wire or powered serial interfaces) or the meters’ core metrological performance covered in other parts of the IEC/EN 62052/62053 family.

Key topics and requirements

• Definition and classification of pulse output device types (passive two‑wire devices for pulse transmission).
• Electrical interface requirements: pulse voltage/current characteristics, polarity, pulse duration and spacing, contact behaviour and impedance.
• Environmental and mechanical requirements: temperature range, humidity, vibration, ingress protection and mechanical endurance.
• Insulation, electrical safety and protection against transient voltages.
• Test methods and performance criteria to verify pulse integrity, timing accuracy, durability and conformity.
• Marking, documentation and connection/installation instructions for compatibility with receiving equipment (tariff counters, data loggers, remote readers).

Typical use and users

Manufacturers of electromechanical and electronic electricity meters, meter module and accessory suppliers, utilities and network operators integrating meter outputs into tariff, billing or data‑collection systems, test laboratories performing conformity tests, and regulatory bodies specifying interface requirements for meter installations.

Related standards

This part is one element of the IEC/EN 62052 / 62053 family (standards for AC electricity meters and particular requirements). Closely related documents include general requirements for electricity meters (IEC/EN 62052‑11) and other parts of IEC 62053 that cover specific meter types and accuracy classes. National adoptions (BS EN, DIN EN, UNE EN, etc.) reproduce the EN/IEC text with local forewords.

FAQ

Q: What is this standard?

A: It is the British/European adoption of IEC/EN 62053‑31 (1998/1999) specifying particular requirements for passive two‑wire pulse output devices used with AC electricity meters.

Q: What does it cover?

A: It covers electrical, mechanical and environmental requirements, test methods and marking for pulse output devices that transmit energy pulses from meters to external receivers (tariff devices, data loggers), limited to passive two‑wire arrangements.

Q: Who typically uses it?

A: Meter and accessory manufacturers, utilities, test laboratories and conformity assessment bodies, and technical teams responsible for integrating meter pulse outputs into billing and monitoring systems.

Q: Is it current or superseded?

A: The original IEC 62053‑31 (1998) / EN 62053‑31 (1999 national adoptions) has been the basis for national publications, but national committees have taken various actions since; the IEC publication was subsequently withdrawn in some national catalogs (for example the Norwegian committee records a withdrawal action in 2022 and references replacements in the 62052/62053 family). Users should check the current status with their national standards body or BSI for the definitive national position before relying on it.

Q: Is it part of a series?

A: Yes — it is a part of the IEC/EN 62052 / 62053 series covering AC electricity metering equipment and particular requirements for metering and meter components.

Q: What are the key keywords?

A: Electricity metering, pulse output, two‑wire interface, electromechanical meter, electronic meter, pulse transmitter, IEC 62053, EN 62053‑31.
