The international breakthrough for test blocks came with extensive deliveries of test blocks for the Sizewell B reactor in the UK during the 80s. Since then hundreds of test specimens have been developed and manufactured according to our clients specific requirements worldwide. Uddcomb has unique experience and capability regarding the development and implantation of defects in test blocks/test specimens.

• Geometric defects
• Weld solidification cracks
• Lack of fusion
• Mechanical fatigue cracks
