This European standard specifies requirements for the design, material, manufacturing and testing of pressure vessels and pressure vessel parts. The allowed materials are specific grades with an elongation equal or less than 15% as specified in the following material standards: - EN 1561 Founding - Grey cast irons - EN 1563 Founding - Spheroidal graphite cast irons - EN 13835 Founding - Austenitic cast irons This standard is to be used in addition to the general requirements for unfired pressure vessels under EN 13445: Unfired Pressure Vessels. Allowed cast irons grades, corresponding design limitations and service conditions are given in Tables 4.1-1 and 4.1-2. Special precautions are required when using cast iron with elongation equal or less than 15% to attain the same safety level as when using cast iron with elongation higher than 15%. Service restrictions and limitations are given in Clause 4. Cast iron with elongation equal or less than 15% shall only be used for pressure equipment when operational and technical advantages are dictating its use instead of the cast iron grades given in EN13445-6. For relationship with EU Directives, see informative annex ZA, which is an integral part of this standard.
