National foreword
This Draft for Development is the official English language version of CEN/TS 15053:2005.
This publication is not to be regarded as a British Standard.
It is being issued in the Draft for Development series of publications and is of a provisional nature because details for these types of test specimens have not previously been covered by formal standardization. It should be applied on this provisional basis, so that information and experience of its practical application may be obtained.
Comments arising from the use of this Draft for Development are requested so that UK experience can be reported to the European organization responsible for its conversion to a European standard. A review of this publication will be initiated 2 years after its publication by the European organization so that a decision can be taken on its status at the end of its 3-year life. Notification of the start of the review period will be made in an announcement in the appropriate issue of Update Standards.
According to the replies received by the end of the review period, the responsible BSI Committee will decide whether to support the conversion into a European Standard, to extend the life of the Technical Specification or to withdraw it. Comments should be sent in writing to the Secretary of BSI Technical Committee WEE/46, Non-destructive testing, at British Standards House, 389 Chiswick High Road, London W4 4AL, giving the document reference and clause number and proposing, where possible, an appropriate revision of the text.
A list of organizations represented on this committee can be obtained on request to its secretary.
Cross-references
The British Standards which implement international or European publications referred to in this document may be found in the BSI Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Search” facility of the BSI Electronic Catalogue or of British Standards Online.
This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.

This Technical Specification (CEN/TS) was approved by CEN on 7 May 2005 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit theircomments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS availablepromptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,Slovenia, Spain, Sweden, Switzerland and United Kingdom.

1 Scope
This Technical Specification is established to consider and define discontinuities-types to be exhibited in test specimens for use in practical Non Destructive Testing examinations. According to EN 473:2000, Clause 7.1.3.3, the discontinuities contains in the test specimens may be natural, artificial or implanted.
Acoustic Emission Testing, Infrared Thermography Testing and Leak Testing need not define discontinuity-type, due to their specific approach (e.g. replaced in AT by artificial sources).

Minimum length of surface discontinuity: 1 mm.
Remote VT:
Depends on the goal of the test.
6 Surface conditions
The specimen shall have a surface finished free from loose products of corrosion and/or protective finishes in such a way that it shall provide sufficient access for NDT methods to be used.
7 Number of discontinuities in each sample
Specimen shall contain, as a minimum, one planar and/or volumetric discontinuity having location and dimensions suitable for the applicable NDT method.
8 Radiographic interpretation test (radiographs)
8.1 Definition
Radiographic interpretation test is constituted by radiographs (original or copy), exhibiting a sufficient range of artefacts material/structural anomalies and densities, to provide a realistic and unambiguous test of the ability of a radiographic interpreter to read, interpret and accurately report the results of radiographs.
8.2 Conditions
Radiographs shall be in good condition for viewing (verified and attested before the beginning of each exam session, by one jury Level 3 RT who belongs to the board of examiners), and shall contain, as a minimum, one indication and should contain not more than five different types of indications.
The use of radiograph copies or digitally reproduced is not precluded if the quality of the copy is achieved in respect of density, contrast, definition and sensitivity. They have to meet the minimum requirements of the specification applied for the original radiographs.
Radiographs may be of any size providing a suitable film viewer.
Examination centres shall hold representative radiographs of the product sectors they are approved for.
For In Service Inspection industrial sector, the range of radiographs shall include those relevant of the two following product sectors: weldings (w) and castings (c).
8.3 Quality
Radiographs shall be produced in accordance with the appropriate standard and also with respect to exposure parameters, resulting optical density and processing.
Image Quality Indicators of an internationally recognized type, shall be visible on each test specimen radiograph.
To unambiguously determine indication location by a candidate, radiographs shall contain a sufficient number of marker points, at least not less than two.

Revisions
British Standards are updated by amendment or revision. Users of British Standards should make sure that they possess the latest amendments or editions.
It is the constant aim of BSI to improve the quality of our products and services. We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical committee responsible, the identity of which can be found on the inside front cover. Tel: +44 (0)20 8996 9000. Fax: +44 (0)20 8996 7400.

In response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as British Standards, unless otherwise requested.
