DIN 50136 is a withdrawn German standard for a flattening (ring fold) test on metallic tubes, used to assess tube integrity and formability. New work references the current tube-test standards instead. To match this to your program, talk with our team.
What DIN 50136 Covered
The flattening test compresses a short length of tube between platens until the walls meet or a defect appears, revealing weld soundness, ductility, and formability of the tube.
Current Replacement
Because DIN 50136 has been withdrawn, current tube evaluation uses the maintained flattening and ring test standards. Legacy references can be mapped onto these with documented equivalence; for ring tensile evaluation see ISO 8496.
Reading the Designation
Cited as DIN 50136 with its year. Confirm whether the controlling document expects a current tube-test standard.
Related Standards
ISO 8496 is a current ring tensile method for metallic tubes.
