How to identify a fake MTC type 3.2

Common mistake in MTC type 3.2:

  1. Missing one of “customer name”, “customer number” or “purchase order”, “address”, “date of issue”, “shipper”, “purchaser”, “distenation”, ” certificate number”, “location”. In case of MTC verification, we are unable to trace in manufacturer data and in Surveyor report.
  2. Test samples were missed details of sample number, size, dimension, location of test.
  3. Plate marking or MTC shall not be identified the sequence plate number and heat number, test sample number,
  4. The identification stamping were not used low-stress (dot-, vibratory-, and round V-) stamps
  5. Orignal markings were miss special stamp/stencile of rule requirements.
  6. Vendor supplies a scanned MTC with black/white color in lieu of full color/ dully stamped by Surveyor.
