Summary:
This European Standard specifies requirements for the design, materials, manufacturing and testing of pressure vessels and pressure vessel parts intended for use with a maximum allowable pressure, PS, equal or less than 100 bar and shell wall thicknesses not exceeding 60 mm, which are constructed of ferritic or austenitic spheroidal graphite cast iron. The thickness limitation of the shell does not apply to thickness of flanges, reinforcements, bosses etc. The allowable grades do not include lamellar graphite cast iron grades for ferritic and austenitic grades, which are explicitly excluded from this European Standard because of low elongation and brittle material behaviour, which requires the use of different safety factors and a different approach.
La présente Norme européenne établit les spécifications pour la conception, les matériaux, la fabrication et le contrôle des récipients sous pression et de leurs parties sous pression, prévus pour utilisation à une pression maximale admissible, PS, inférieur ou égale à 50 bar et d'épaisseur de paroi de virole ne dépassent pas 60 mm, fabriqués en fonte à graphite sphéroïdal.NOTE Les nuances admises de fonte à graphite sphéroïdal sont énumérées dans les Tableaux 5.1-1 et 5.1-2. Les conditions de service sont données à l'article 4.
