National foreword

This British Standard is the English language version of EN 60454-3-12:1998 It is

identical with IEC 604543-12:1998

The UK participation in its preparation was entrusted by Technical Committee GEW15, Insulating niaterials, to Subcommittee GEL/15/3, Material specifications, which has the responsibility to:

- aid enquirers to understand the text;

- present to the responsible internationaì/European committee any enquiries

on the interpretation, or proposals for change, and keep the TJK interests informed

- monitor related international and European developments and promulgate them in the UK

This British Standard, having

been prepared under the

direction of the Electrotechnical

Sector Board, was published

under the authority of the

Standards Board and comes into

effect on 15 October 1998

O BSI 1998

ISBN O 580 30060 9

A list of organizations represented on this subcommittee can be obtained on request

to its secretary

From 1 January 1997, ali IEC publications have the number 60000 added to the old

number For instance, IEC 27-1 has been renumbered as IEC 60027-1 For a period

of time during the change over from one numbering system to the other, publications may contain identifiers from both systems

pu.rposes, will be withdrawn after Sheets 1 to 19 (inclusive) of BS EN 604543 have been published

Cross-references

Attention is &awn to the fact that CEN and CENELEC standards normally include

an annex which lists normative references to international publications with their corresponding European publications The British Standards which implement these international or European publications may be found in the BSI Standards

Catalogue under the section entided "International Standards Correspondence Index", or by using the "Find" facihty of the BSI Standards Electronic Catalogue

A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application

Compliance with a British Standard does not of itself confer immunity from legal obligations

INTRODUCTION

This International Standard is one of a series which deals with pressure-sensitive adhesive tapes, intended primarily for electrical purposes

The series consists of three parts:

- Part 1: General requirements (IEC 60454-1)

- Part 2: Methods of test (IEC 60454-2)

- Part 3: Specifications for individual materials (IEC 60454-3)

This standard contains one of the sheets comprising part 3 as follows:
