scope:

This AD 2000-Merkblatt applies to non-alloy and low-alloy spheroidal-graphite cast iron for the construction of pressure vessels and parts operating at working temperatures and at ambient temperatures within the limits given in tables 1 and 2. For temperatures below -10 oC, AD 2000-Merkblatt W 10 shall also be taken into consideration, See also of AD 2000-Merkblatt W 0.

The production of spheroidal-graphite cast iron for the construction of pressure vessels presupposes an adequate level of experience on the part of the suppliers. The relevant third party shall be provided with initial proof of this.

Due account shall be taken of casting practice when designing pressure vessels made of spheroidal-graphite cast iron if blowholes, cracks and peak stresses are to be avoided.

For value housings, AD 2000-Merkblatt A 4 applies.
