DIN EN 12560-2 2013-12 PDF

Full title and description

DIN EN 12560-2:2013-12 — Flanges and their joints — Dimensions of gaskets for Class-designated flanges — Part 2: Spiral wound gaskets for use with steel flanges. This German version of EN 12560-2 specifies dimensions, design, types, designation, materials and marking for spiral wound gaskets intended for use with flat-face (type A) and raised-face (type B) steel flanges in the Class range covered by EN 1759-1.

Abstract

This part of EN 12560 gives dimensional data, design rules, allowable ranges and marking requirements for spiral-wound gaskets (including centring rings sized for imperial bolting) for Class-designated steel flanges (Class 150 up to Class 1500 for DN 15 to DN 600, and Class 2500 up to DN 300). It excludes certain flange facing types (tongue-and-groove, spigot-and-recess) and aligns its dimensional basis with ASME B16.20 where relevant. The 2013 revision updated normative references, revised gasket requirements and removed the informative Annex A on asbestos.

General information

• Publication date: December 2013 (2013-12).
• Publisher: DIN (Deutsches Institut für Normung) — German version of the CEN standard EN 12560-2.
• ICS / categories: 23.040.80 (Seals for pipe and hose assemblies / Flanges and joints area).
• Edition / version: DIN EN 12560-2:2013-12 (replaces the 2001 edition).
• Number of pages: 17 (DIN publication specification).

Scope

Specifies the geometrical dimensions, types, designation, materials and marking of spiral-wound gaskets for use with type A (flat face) and type B (raised face) steel flanges complying with EN 1759-1 for the Class designation range specified (Class 150–1500 for DN 15–DN 600; Class 2500 up to DN 300). The standard excludes some facing types (tongue-and-groove and spigot-and-recess) and provides centring‑ring dimensions intended for imperial (inch) bolting; it is intended to harmonize European gasket dimensions with established ASME practice where applicable.

Key topics and requirements

• Dimensional specifications and tolerances for spiral‑wound gaskets (thicknesses, inner/outer diameters and centring ring sizes).
• Design types and designation/coding rules for spiral‑wound gasket variants.
• Materials and construction details (metallic winding, filler materials, centring rings) and marking/identification requirements.
• Range of Class designations and corresponding nominal sizes (DN/NPS) covered by the part.
• Exclusions and special notes — e.g., tongue-and-groove and spigot-and-recess facings are not covered; guidance on purchaser information to be supplied.
• Alignment with ASME B16.20 dimensional bases where applicable and updates to normative references (2013 revision).
• Removal of the previous informative asbestos annex and related warning text in the 2013 revision (administrative/health-note update).

Typical use and users

Used by pipeline and piping engineers, flange and gasket manufacturers, valve and fittings suppliers, procurement/specifications teams, pressure‑equipment designers, inspection and testing laboratories, and plant maintenance personnel who need standardized gasket dimensions and marking for flanged joints in industrial piping (petrochemical, power, process plants, water and utilities).

Related standards

Directly referenced and related documents include EN 1759-1 (circular steel flanges, class-designated), the EN 12560 series parts (Part 1, 3–7 covering other gasket types), and internationally ASME B16.20 (spiral wound gaskets) which informed dimensional choices. The 2013 edition replaces the earlier EN 12560-2:2001 edition.

FAQ

Q: What is this standard?

A: DIN EN 12560-2:2013-12 is the German national version of EN 12560-2 (2013), the European standard that specifies dimensions, designs, materials and marking for spiral‑wound gaskets used with steel flanges.

Q: What does it cover?

A: It covers spiral‑wound gaskets for type A (flat face) and type B (raised face) steel flanges in the Class ranges defined (Class 150–1500 for DN 15–DN 600; Class 2500 up to DN 300), giving dimensions, tolerances, types, materials and marking rules; some flange facing types are explicitly excluded.

Q: Who typically uses it?

A: Piping and mechanical engineers, gasket and flange manufacturers, procurement/specification writers, inspection and test houses, and maintenance staff in industries using class‑designated steel flanges (process plants, utilities, oil & gas, power generation, etc.).

Q: Is it current or superseded?

A: The 2013-12 edition (DIN EN 12560-2:2013-12) replaced the previous 2001 edition. National listings (DIN / other national bodies) show the 2013 version as the applicable edition; no later EN-wide replacement of Part 2 was identified at the time of this product page preparation. If you need absolute currency for procurement or compliance, check the national standards body for the latest status before placing an order.

Q: Is it part of a series?

A: Yes — EN 12560 is a multipart series covering gasket types for Class‑designated flanges (Part 1: non-metallic flat gaskets; Part 2: spiral wound; Part 3: PTFE envelope gaskets; Part 4: corrugated/filled metallic gaskets; Part 5: metallic ring‑joint gaskets; Part 6: kammprofile/serrated metal gaskets; Part 7: covered metal jacketed gaskets).

Q: What are the key keywords?

A: Spiral wound gasket, flange gasket, flange joint, centring ring, Class-designated flange, EN 12560-2, EN 1759-1, ASME B16.20, gasket marking.
