European-standard flange

“European-standard flange” describes a broad standards context but does not identify a standard part, material family or flange type. EN 1092 is one European framework for circular flanges, but the general title alone does not mean EN 1092-1, a DIN designation or another specific system. Safe selection requires the standard number and edition, flange type, PN designation, facing, material and dimensional pattern to be stated explicitly in project documents. No standards system or mating compatibility is assumed from the name.
