DVM Test Notched Bar Impact Value

[WPM3022]

Hello

I have a drawing of a shaft which nominates mechanical material properties as:

Yeild = 460 MPa min
tensile = 690-840 MPa
breaking elongation = 15%
notched bar impact value - DVM test = 38 Joules

It is the DVM test which is confusing me: I cannot find any information on where/how/possibility of converting a DVM test to a more standard Izod or Charpy test.

Any information is greatly welcome.


Drawing was published in 1979, if that helps.

DVM is a designation for a specific impact test specimen in DIN 50115. This standard was issued first in 1952. Last edition is 1994 and is meanwhile historic (withdrawn).
The dimensions of the specimen are 55 * 10 * 10 mm.
The notch ist 3 mm deep and has a U-form with a radius of 1 mm. Cross-section is 0,7 cm2.
The specimen is comparable to an ISO-U-specimen defined in ISO 148-1:2016 with the difference that ISO-U has a notch depth of 5 mm (cross-section 0,5 cm2)
