National foreword

This British Standard is the English language version of EN 1330‑2:1998.

The UK participation in its preparation was entrusted to Technical Committee WEE/46, Non-destructive testing, which has the responsibility to:

aid enquirers to understand the text;
present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed;
monitor related international and European developments and promulgate them in the UK.

A list of organizations represented on this committee can be obtained on request to its secretary.

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.

This British Standard, having been prepared under the direction of the Engineering Sector Committee, was published under the authority of the Standards Committee and comes into effect on 15 December 1998

Summary of pages

This document comprises a front cover, an inside front cover, pages i and ii, the EN title page, pages 2 to 11 and a back cover.

This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.

This European Standard was approved by CEN on 20 September 1998.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

Foreword

This European Standard has been prepared by Technical Committee CEN/TC 138 “Non-destructive testing”, the secretariat of which is held by AFNOR.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 1999, and conflicting national standards shall be withdrawn at the latest by April 1999.

This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This European Standard is considered to be a supporting standard to those application and product standards which in themselves support an essential safety requirement of a New Approach Directive and which make reference to this European Standard.

This Standard consists of the following parts:

Part 1: General terms

Part 2: Terms common to the non-destructive testing methods;
Part 3: Terms used in industrial radiographic testing;
Part 4: Terms used in ultrasonic testing;
Part 5: Terms used in eddy current testing;
Part 7: Terms used in magnetic particle testing^a;
Part 8: Terms used in leak testing;
Part 9: Terms used in acoustic emission;
Part 10: Terms used in visual testing^a.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

Introduction

To date, it is anticipated that EN 1330 will comprise at least 10 parts prepared separately by groups of experts, each group consisting of experts in a given NDT (non-destructive testing) method (for parts 3 to 10).

A comparative examination of these parts has shown the existence of common terms that are often defined differently. These terms have been taken from parts 3 to 9 and then split into two categories:

General terms corresponding to other fields such as physics, electricity, metrology, and already defined in international documents. These terms are the subject of part 1;
Common terms specific to NDT. These terms, the definitions of which have been harmonized in an Ad Hoc group, are the subject of part 2.

In view of the nature of the approach taken, the lists of terms in parts 1 and 2 are in no way exhaustive.

Some of the terms defined in this part can need more precise definitions related to a specific method.
