Steel rail weld test block GHT-5 (TB/T 2658.21 standard)
Rail GTS-60C test block (TB/T 2658.21 standard)
Difficult defect weld joint test block YN-1 (total length of test block 460mm, extension needs to be customized, cost is additional)
Ultrasonic testing test blocks should be equipped in the testing production facility, including:
Standard test blocks: CS-1-5 test block, CSK-1A or IIW test block, etc
Comparative test blocks: WGT-3 test block and stair step test block, etc
Physical comparison test blocks: such as GTS-60 test block and GTS-60C test block recommended in Attachment 2.
Rail weld inspection test block: GHT-1 test block, GHT-5 test block or equivalent GHT-2, GHT-3, GHT-4 test block.
At the same time, attention should be paid to collecting various steel rails with natural damage as physical comparison test blocks.
