1. Annex 1 Mechanical Test Results; Tensile Test EN 4135-080
Please check if the “Minimum Tensile Requirement (KN) 35kN is correct. ISO 9152 require 46kN as a minimum.

2. Annex 4 Statement of Inspection (general)
For the Tensile Test on Finish Good the results are marked with
e.g. NF means “No Failure”
HR means “Head rupture”
What the abbreviation for “TR” ?

  Hi Heinrich,
  
  1. Minimum tensile requirement for diameter 8 is 46kN. I have made a typo error on annex-1 requirement should be 46 instead of 35. You can see correct requirement (46kN mi.) on Annex-4
  2. TR means thread failure. Actually laboratory techician should indicate it as TF but as an old habit he have indicated it as TR.
