Full title and description

St SA TS IEC 62763-2014 — Electrotechnical vocabulary: Electrical environments for low-voltage equipment — Definitions and classifications (adoption of IEC 62763:2013 as a South African Technical Specification). This document provides terminology and classification of electrical environments affecting low-voltage equipment, intended to harmonize terms and definitions for use in specifying and testing equipment performance under different environmental electromagnetic and electrical conditions.

Abstract

This South African Technical Specification adopts IEC 62763 (published internationally in 2013/2014) and gives definitions and classifications of electrical environments relevant to low-voltage electrical and electronic equipment. It describes types of electrical disturbances and the characteristics of environments (for example overvoltages, supply voltage variations, and electromagnetic phenomena) so that equipment requirements, test conditions and installation practices can be consistently specified. The TS is intended to support designers, test laboratories, specifiers and regulators by providing common vocabulary and environmental categories used when assessing equipment immunity and service conditions.

General information

• Status: South African Technical Specification (adoption of IEC standard)
• Publication date: 2014
• Publisher: SABS (South African Bureau of Standards) / IEC (original source)
• ICS / categories: 29.080 (Electrical equipment in general), 17.140 (Electromagnetic compatibility)
• Edition / version: 2014 (adoption of IEC 62763)
• Number of pages: Typically around 20–30 pages (original IEC 62763 is a concise vocabulary/TS)

Scope

The specification defines terms and classifies electrical environments that affect low-voltage equipment, including supply system conditions, transient phenomena, steady-state deviations and electromagnetic disturbances. It covers definitions used to describe the severity and characteristics of electrical environments so that equipment immunity levels and test conditions can be matched to realistic installation and service conditions. The document is not a test standard itself but provides vocabulary and environmental descriptors referenced by performance and EMC standards for low-voltage equipment.

Key topics and requirements

• Definitions of electrical environment types: supply variations, dips, interruptions, overvoltages and transients
• Classification schemes for environment severity and categories for installation sites
• Descriptions of electromagnetic phenomena relevant to low-voltage equipment service
• Guidance on matching equipment immunity requirements to environmental categories
• Terminology harmonized with IEC usage to support consistent specification and testing

Typical use and users

Used by product standards writers, equipment designers, test laboratories, compliance engineers, specification authors and regulatory bodies. Typical applications include defining environment-related requirements in low-voltage equipment standards, selecting appropriate immunity test levels, writing procurement specifications and assessing installation conditions for electrical and electronic devices.

Related standards

Relevant related documents include IEC 61000 series (electromagnetic compatibility standards), other IEC/ISO vocabulary and terminology publications, and national adoptions such as SANS standards for EMC and low-voltage equipment. Standards that reference environment classifications from IEC 62763 include immunity and functional safety standards for electrical equipment operating on supply networks.

FAQ

Q: What is this standard?

A: It is a South African Technical Specification adopting IEC 62763 (2013/2014) that provides vocabulary and classifications for electrical environments affecting low-voltage equipment.

Q: What does it cover?

A: It covers definitions and classification of electrical environment phenomena—such as supply voltage variations, dips, interruptions, overvoltages and electromagnetic disturbances—to enable consistent specification of equipment immunity and installation conditions.

Q: Who typically uses it?

A: Product standards writers, designers, test laboratories, compliance engineers, procurement/specification teams and regulators use it to align requirements and tests with realistic electrical environments.

Q: Is it current or superseded?

A: The document is an adoption from 2014 of IEC 62763; users should check for later revisions or superseding national standards, but as published it represents the IEC vocabulary at that time. Verify with the national standards body for the most current status.

Q: Is it part of a series?

A: It complements the IEC 61000 series (EMC standards) and other IEC vocabulary/terminology publications; it is intended to be used alongside EMC and low-voltage equipment standards rather than as a test method.

Q: What are the key keywords?

A: Electrical environment, low-voltage equipment, classification, overvoltage, transient, supply variation, electromagnetic disturbance, vocabulary.
