Specification according to DIN 28013

r1 = 0,8 * da
r2 = 0,154 * da
da = Da = D
h1 > = 3 * s
h2 = 0,255 * da 0,635 * s
h3 = h1 + h2
H = h3 + s
V 0,13 * (da-2*s)³ + (da-2*s)² * h1 * 0,785
Aa 1,08 * da² + h1 * da * 3,14
Ai 1,08 * (da-2*s)² + h1 * (da-2*s) * 3,14

(r1: Dish radius | r2: Knuckle radius | da: Outer diameter | h1: Straight flange height | h2: Depth of dishing | h3: total internal head height | s: Wall thickness | V: Volume | Aa: outer surface | Ai: inner surface)
