Full title and description

STB DD ENV 50091-3-1999 (2000) — Specification for uninterruptible power systems (UPS) — Part 3: Performance requirements and test methods. This national publication reproduces the DD ENV 50091-3 technical content addressing performance specification and test methods for UPS with electrical energy storage on the d.c. link, issued locally under the STB designation in 2000 and originally prepared as DD ENV 50091-3:1999.

Abstract

This document defines functional and test requirements for electronic uninterruptible power systems (UPS) whose energy storage is on the d.c. link. It specifies ambient and electrical service conditions, input/output performance parameters, type and compliance tests (electrical and non-electrical), classification by performance and required technical data sheet information to allow consistent specification, testing and comparison of UPS equipment.

Scope

The standard applies to electronic UPS units with electrical energy storage on the d.c. link and covers the method of specifying performance and the test procedures needed to verify declared characteristics. It addresses continuity of supply as the primary function and also sets limits and tests relevant to power quality, electromagnetic compatibility, environmental conditions, mechanical characteristics and acoustics that affect UPS performance and suitability for intended installations. The document is aimed at providing a uniform basis for specification, testing and comparison of UPS equipment.

Key topics and requirements

• Definitions, normative references and general terms used for UPS performance specification.
• Ambient and environmental service conditions (operating, storage and transport conditions and tests).
• Electrical service conditions: detailed UPS input/output parameters, by-pass arrangements, control and monitoring signals, stored/restored energy modes, EMC considerations.
• Type and electrical performance tests: procedures for rating, factory and on-site testing, and verification of declared characteristics.
• Non-electrical tests: mechanical, acoustic noise, enclosure and environmental endurance tests.
• Compliance tests and classification: methods to classify UPS by performance and prepare technical data sheets with manufactured-declared specifications.
• Annex material: reference non-linear load, EMC guidance and UPS type descriptions.

Typical use and users

Used by UPS manufacturers and designers for defining product performance and factory test regimes; by independent test laboratories and certification bodies verifying declared characteristics; by procurement and specifications engineers in telecommunications, data centers, industrial facilities and critical infrastructure who need a common basis to compare UPS products; and by installation and maintenance teams for acceptance and on-site verification testing.

Related standards

Directly related and subsequent standards include EN 62040-3 (method of specifying performance and test requirements for UPS, successor editions 2001, 2011, 2021), IEC/EN documents on semiconductor converters and UPS safety and EMC (for example IEC 60146 series and related EN 50091 parts), and national adoptions/revisions that replaced ENV 50091-3. This DD/ENV prestandard was incorporated into the EN 62040 series in later editions.

FAQ

Q: What is this standard?

A: It is the DD ENV 50091-3 prestandard reproduced locally as STB DD ENV 50091-3-1999 (2000), providing performance requirements and test methods for uninterruptible power systems (UPS).

Q: What does it cover?

A: It covers functional definitions, ambient and electrical service conditions, electrical and non-electrical testing procedures, classification by performance and the format for technical data sheets so declared UPS characteristics can be specified and verified.

Q: Who typically uses it?

A: UPS manufacturers, test laboratories, certification bodies, procurement/specification engineers for data centers and critical facilities, and installation/maintenance personnel performing acceptance testing. (General practice based on the document’s scope.)

Q: Is it current or superseded?

A: Superseded/withdrawn — the DD ENV 50091-3 text has been replaced in practice by the EN/IEC 62040-3 series (EN 62040-3 editions from 2001 onward and later revisions). Users should refer to the current EN/IEC 62040-3 edition for up-to-date normative requirements.

Q: Is it part of a series?

A: Yes — it is Part 3 of the ENV/EN 50091 family addressing UPS; related parts cover safety, installation and other aspects of UPS systems and the later EN 62040 series consolidated performance/test requirements into Part 3 (method of specifying performance and test requirements).

Q: What are the key keywords?

A: UPS, uninterruptible power system, performance requirements, test methods, DC link, EMC, classification, technical data sheet.
