Frequently Asked Questions
ECISS/TC 29/SC 3/WG 4 is a Subcommittee within the European Committee for Standardization (CEN). It is named "Butt welded fittings in austenitic and austenitic ferritic (duplex) stainless steels" and is responsible for: Production of standards covering stainless steel fittings. This committee has published 3 standards.
ECISS/TC 29/SC 3/WG 4 develops CEN standards. The scope of work includes: Production of standards covering stainless steel fittings. Currently, there are 3 published standards from this subcommittee.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Subcommittee (SC) in CEN operates under a Technical Committee and focuses on a specific subset of the TC's scope. Subcommittees develop standards and technical specifications in their specialized area, reporting to their parent Technical Committee. They may also have working groups for detailed technical work.

1.1 This European Standard specifies the technical delivery requirements for seamless and welded butt-welding fittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of austenitic and austenitic-ferritic (duplex) stainless steel which are intended for pressure and corrosion resisting purposes at room temperature, at low temperature or at elevated temperatures.
It specifies:
the type of fittings;
type A (see 7.2)
type B (see 7.3)
the steel grades;
the mechanical properties;
the dimensions and tolerances;
the requirements for inspection and testing;
the inspection documents;
the marking;
the handling and packaging.
NOTE In the case of a harmonised supporting standard for materials, presumption of conformity to the Essential Requirement(s) (ESRs) is limited to technical data of materials in the standard and does not presume adequacy of the material to a specific item of equipment. Consequently the technical data stated in the material standard should be assessed against the design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive (PED) are satisfied.
1.2 Unless otherwise specified in this European Standard the general technical delivery requirements in EN 10021 apply.
