    These numbers don’t align though. 4271 is not a Bxxx or Dxxx and also isn’t on that diagram on the left. I’m so confused rn.

      B and D are weight classes. B 125 is tested to 125 kN, D 400 is tested to 400 kN.

      DIN 4271 tells you how manholes of class B are to be build.

        I see the number in the diagram now after looking more closely. Also seems the number is upside down in the game.
