1Scope
This European Standard specifies methods for the manual ultrasonic testing of fusion welded joints in
metallic materials equal to and above 8 mm thick which exhibit low ultrasonic attenuation (especially that due to scatter).It is primarily intended for use on full-penetration welded joints where both the welded and parent material are ferritic.
The techniques may also be used:
–on materials other than those stated,–on partial-penetration welds,–with automated equipment,if required by specification.
Where material-dependent ultrasonic values are specified in this standard, they are based on steel having an ultrasonic sound velocity of (5920 t  50) m/s for longitudinal waves, and (3255 t  30)m/s for transverse waves.This is to be taken into account when examining materials with a different velocity.
The standard specifies four testing levels, each corresponding to a different probability of detection of imper-fections. 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 use in special applications, shall be in accordance with the general requirements of this standard and may only be used when defined by specification.
This standard may be used for the assessment of indications, for acceptance purposes, by either of the following methods:
1)evaluation based primarily on length and echo amplitude of the signal indication;
2)evaluation based on characterization and sizing of the indication by probe movement methods.The methods used shall be specified.
2Normative references
This European Standard incorporates by dated or undated references provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed as follows.For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies:

3Definitions and symbols
For the purposes of this standard, the definitions given in EN 1330-4 and EN 12062 apply.For quantities and symbols, see table 1.
Indications shall be considered to be either longitudinal or transverse, depending on the direction of their major dimension with respect to the weld axis, x , in accordance with figure 2.
