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.”.

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.”.
