Overview
EN 12560-6:2003 is a CEN European Standard that defines the construction, dimensions and marking of covered serrated metal gaskets intended for use with steel flanges that conform to prEN 1759-1. It specifically covers gaskets for Class-designated flanges in Class 150, 300, 600, 900, 1500 and 2500 and for flange sizes up to and including NPS 24. The standard provides practical rules for manufacturers, specifiers and purchasers to ensure interchangeability and correct identification of serrated metal flange gaskets.
Key topics and requirements
- Scope and applicability - Gaskets for steel flanges to prEN 1759-1 for the listed pressure classes and nominal pipe sizes (to NPS 24).
- Construction - Requirements for covered serrated metal gasket construction (metal core with serrated face and a cover), covering profile and basic form factors.
- Dimensions - Standardized dimensions and tolerances so gaskets fit Class-designated flanges consistently.
- Marking - Identification and marking rules to enable traceability, correct selection and conformity verification.
- Exclusions and application notes - The standard does not cover serrated covered metal-based heat exchanger gaskets with pass bars or very large vessel gaskets, although its principles may be applied when no dedicated standard exists.
- Ordering information - Annex A lists the information the purchaser should supply when material or service conditions are left to the supplier (e.g., service medium, temperature, pressure class, flange standard).
(Note: EN 12560-6 provides general requirements; detailed material selection, sealing performance parameters or specific serration geometries should be taken from manufacturer data or complementary standards.)
Applications
- Pipeline and process industries - Specifying reliable flange gaskets for oil & gas, petrochemical, power generation and chemical plants.
- Gasket manufacturers - Designing and producing serrated metal gaskets to meet European class-flange compatibility.
- Plant engineering and maintenance - Selecting correctly sized and marked gaskets for flange replacements and routine maintenance.
- Procurement and QA - Ensuring purchased gaskets meet standardized dimensions and marking for interchangeability and traceability.
