ISO Flange System
The metric countries, following ISO (International Standards Organization) recommendation, base the dimensions of all stock upon geometric progressions instead of arithmetic. The first preference or coarsest number sequence is 10, 16, 25, 40, 63, 100, which has 5 uniform steps per decade. The second preference series is 10, 12, 16, 20, 25, 32, 40,50, 63, 80, 100, which has 10 uniform steps per decade. These series can be multiplied by factors of 10 to obtain standard nominal stock sizes.
