Overview

EN 12560-4:2001 (CEN) is the European standard that defines requirements for corrugated, flat or grooved metallic and filled metallic gaskets used with steel flanges. The standard specifies the dimensions, types, design and marking requirements for these gasket types when used with flanges complying with EN 1759-1. It applies to Class-designated flanges for Class 150, 300, 600, 900 and 1500 up to NPS 24 (DN600), and Class 2500 up to NPS 12 (DN300).

Key Topics

  • Gasket types covered
    • Corrugated metallic gaskets
    • Flat metallic gaskets
    • Grooved metallic gaskets
    • Filled metallic (metallic with filler) gaskets
  • Scope of application
    • Designed for steel flanges in Class-designated systems (per EN 1759-1)
    • Size and pressure class limits as stated above (NPS/DN and Class 150–2500)
  • Design and dimensional requirements
    • Standardized gasket geometries and profiles to ensure flange compatibility
    • Dimensional limits that align with the mating flange faces and bolting patterns
  • Marking and identification
    • Mandatory marking elements to enable traceability and correct selection
    • Manufacturer identification and type/design designation requirements
  • Quality and consistency
    • Requirements intended to ensure consistent sealing performance across pressure classes and nominal sizes

Applications and Who Uses It

  • Industrial piping and process plants where reliable flange sealing is critical: oil & gas, petrochemical, chemical processing, power generation, and water treatment.
  • Manufacturers of metallic gaskets and sealing components who need to design and mark products to European standards.
  • Pipeline and mechanical engineers, maintenance teams, and procurement specialists selecting gaskets for Class-designated steel flanges.
  • Inspection and compliance professionals verifying that gasket supply and installation meet EN/European regulatory specifications.

Practical Value

  • Ensures interchangeability and compatibility between gaskets and flanges built to EN 1759-1.
  • Helps specify gaskets that match required pressure classes and nominal sizes, reducing leakage risk.
  • Standardized marking improves traceability and quality control in supply chains and maintenance.
