    Can somebody explain why it makes sense that the green underlined number and the red circled number are not the same, please?

      DIN B125 is the class of manhole covers designated for Light to moderate loads. DIN 4271 is the standard for B125 covers that have vents. Obviously. Did you forget everything from German Manhole Cover Standards class at school? ;)
