Foreword
This document EN 1714:1997/A1:2002 has been prepared by Technical Committee CEN/TC 121 "Welding", the
secretariat of which is held by DS.
This Amendment to the European Standard EN 1714:1997 shall be given the status of a national standard, either
by publication of an identical text or by endorsement, at the latest by November 2002, and conflicting national
standards shall be withdrawn at the latest by November 2002.
This document has been prepared under a mandate given to CEN by the European Commission and the European
Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.
Annex A is normative.
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, Malta, Netherlands, Norway, Portugal, Spain,
Sweden, Switzerland and the United Kingdom.
General
As agreed by CEN/TC 121/SC 5 resolution 134/2000, the term “examination” shall be replaced by “testing".
1 Scope
nd
The 2 paragraph shall read now:
“The techniques may also be used:
- on materials other than those stated;
- on partial penetration welds;
- with automated equipment
if required by specification.”.
th
The 4 paragraph shall read now:
“The standard specifies four testing levels, each corresponding to a different probability of detection of
imperfections. Guidance on the selection of testing levels A, B and C is given in annex A. The requirements of the
fourth testing level, which is intended for special applications, shall be in accordance with the general requirements
of this standard and may only be used when defined by specification.”.
th
The 5 paragraph shall read now:
“This standard may be used for the assessment of indications, for acceptance purposes, by either of the following
methods:
…
The methods used shall be specified.”.
2 Normative references
Replace prEN 1712 “Non-destructive examination of welds – Ultrasonic examination of welded joints – Acceptance
levels” by EN 1712 “Non destructive examination of welds – Ultrasonic examination of welded joints – Acceptance
levels”.
Replace prEN 1713 “Non-destructive examination of welds – Ultrasonic examination – Characterization of
imperfections in welds” by EN 1713 “Non-destructive examination of welds – Ultrasonic examination –
Characterization of indications in welds”.
4 General
st
The 1 paragraph shall read now:
“The purpose of this standard is to describe general methods of ultrasonic testing, using standard criteria, for the
most commonly used weld joints. The specific requirements specified by this standard cover the equipment,
preparation, performance of the testing and reporting. The parameters specified, in particular those for the probes,
are compatible with the requirements of EN 1712 and EN 1713, and are also suitable for use with other acceptance
criteria standards. The techniques recommended in this standard are suitable for the detection of those weld
imperfections specified in typical weld acceptance standards. Methods to be used for ultrasonic assessment of
indications and acceptance criteria shall be defined by specification.”.
5.1 Items subject to agreement between the contracting parties
The title shall read now:
"Items to be specified"
Delete the first sentence.
In the French version only, read the fourth dash as "niveaux d’examen;"
5.3 Written testing procedure
st
The 1 paragraph shall read now:
“The definitions and requirements in this standard will normally satisfy the need for a written procedure. Where this
is not the case, or where the techniques described in this standard are not applicable to the weld joint to be
examined, additional written procedures shall be used, if required by specification.”.
10.5 Signal to noise ratio
st
The 1 paragraph shall read now:
“During testing of the weld the noise level excluding spurious surface indications shall remain at least 12 dB below
the evaluation level. This requirement may be relaxed subject to specification.”.
12.3 Testing for imperfections perpendicular to the testing surface
st
The 1 paragraph shall read now:
“Subsurface planar imperfections perpendicular to the testing surface are difficult to detect with single angle probe
techniques. For such imperfections specific testing technique should be considered, particularly for welds in thicker
materials. Use of these testing techniques shall be defined by specification.”.
12.5.4 Indication height
st
The 1 paragraph shall read now:
“Indication height measurement shall be carried out if required by specification. The following method shall be
used:
Where possible, for imperfections which generate more than one distinct peak in the received signal when scanned
in the through-thickness direction, the height (h) shall be measured by a probe movement technique. It is
recommended that when an indication has a measured height of 3 mm and above, the indication height shall be
recorded. However, other higher threshold heights for recording may be defined upon.”.
