Standard test blocks
The standard test block is the foundation of flaw detection, based on the earliest "Dutch test block". After decades of development, domestic industries such as power, petroleum, shipbuilding, steel structures, and cranes have their own industry standards for flaw detection according to their needs, and corresponding standard test blocks have been specified. Shandong Ruixiang Mold Co., Ltd. has been involved in the drafting of national inspection standards since the 1980s and has participated in the revision of 39 inspection standards. In 2013, participated in the revision of the GB/T11345-2013 "Ultrasonic Testing Technology, Testing Levels and Evaluation for Non destructive Testing of Welds" standard. According to the standard regulations, designed and produced corresponding standard flaw detection test blocks. At the same time, participated in the writing and discussion of the ultrasonic part of NB/T47013 (JB/T4730) "Non destructive Testing of Pressure Equipment", provided a large number of experimental test blocks for the expert group, and collected a lot of data in conjunction with experiments, providing important basis for standard revision.
