EN 1714:1997

EN 1714:1997 is a standard + national annex and/or foreword published by the European Committee for Standardization (CEN). Its full title is "Non-destructive examination of welds - Ultrasonic examination of welded joints". This standard covers: This European Standard specifies methods for the manual ultrasonic examination 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. Where specified and appropriate, techniques may also be used : - on materials other than those stated ; - on partial penetration welds ; - with automated equipment by agreement between the contracting parties. Where material dependent ultrasonic values are specified in this standard they are based on steels having an ultrasonic sound velocity of 5920 ñ 50 m/s for longitudinal waves, and 3255 ñ 30 m/s for transverse waves. This is to be taken into account when examining materials with a different velocity. The standard specifies four examination levels, each corresponding to a different probability of detection of imperfections. Guidance on the selection of examination levels A, B and C is given in annex A. The requirements of the fourth examination level, which is intended for special applications, are in accordance with the general requirements of this standard and as agreed between the contracting parties. This standard, by agreement between the contracting parties, permits 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.
