Non-destructive testing of welds. Ultrasonic testing of welded joints. Acceptance levels

Alkalmazási terület

This European Standard specifies ultrasonic acceptance levels, 2 and 3, for full penetration welded joints in ferritic steels, which correspond to the quality levels B and C of EN 25817, respectively. Other acceptance levels can be used by agreement between the contracting parties. An acceptance level corresponding to level D of EN 25817 has not been included in this standard as ultrasonic examination is not recommended for this weld quality. These acceptance levels are applicable to examinations carried out in accordance with the standards referred to in EN 12062. They can, however, be applied in conjunction with other rules, where the same types of reference reflectors for sensitivity setting are used, provided it is agreed between the contracting parties. The standard is applicable to the examination of full penetration ferritic steel welds, with thicknesses from 8 mm up to 100 mm. It can also be used for other types of welds, materials and thicknesses above 100 mm, provided the examinations have been performed with necessary consideration of the geometry and acoustical properties of the component and an adequate sensitivity can be employed to enable the acceptance levels of this standard to be applied. The nominal frequency of probes used in this European Standard is between 2 MHz and 5 MHz unless attenuation or requirements for higher resolution call for another frequency. The use of these acceptance levels in conjunction with frequencies outside this range needs to be considered carefully.
