Overview

EN 14197-2:2003 is a CEN European Standard covering the design, fabrication, inspection and testing of static, non‑vacuum insulated cryogenic vessels. It applies to vessels designed for a maximum allowable pressure greater than 0.5 bar and for the cryogenic fluids referenced in EN 14197‑1. The standard is Part 2 of the EN 14197 series (Part 1: fundamental requirements; Part 3: operational requirements) and does not apply to vessels designed for toxic fluids. Several annexes are normative and informative, supporting material, testing and safety topics.

Key topics and technical requirements

This part of EN 14197 addresses practical engineering and quality requirements for cryogenic tanks and includes:

• Design: design options, common design requirements, design by calculation, stiffening rings, dished ends, cones and openings, reinforcement details for nozzles and pads.
• Structural guidance: rules for cylindrical, spherical and conical shells, plate and flat end design, increased thickness and reinforcement methods.
• Materials: normative and informative annexes that cover base materials and special requirements (e.g., 9% Ni steel and austenitic stainless steels).
• Fabrication: cutting, cold and hot forming, manufacturing tolerances, specific weld details, non‑welded permanent joints and stamping/forming practices.
• Welding & joints: weld designs, seam preparation, specific joints for oxygen service and other critical services.
• Inspection & testing: quality plans, production control test plates, non‑destructive testing (NDT), rectification procedures and pressure testing.
• Safety & service: informative annexes describing relief/pressure‑limiting systems, flammable fluid requirements, and pressure strengthening considerations for specific materials.
• Regulatory linkage: includes an informative annex (ZA) mapping clauses to essential requirements of relevant EU Directives.

Practical applications and users

EN 14197‑2 is intended for organizations involved in the lifecycle of non‑vacuum insulated cryogenic vessels:

• Design engineers and consulting firms preparing calculations and drawings
• Fabrication shops and welders manufacturing cryogenic storage tanks
• Inspection bodies and testing laboratories performing NDT and pressure tests
• Plant operators and safety engineers specifying equipment for industrial gases, LNG, and cryogenic storage (non‑toxic fluids)
• Notified bodies and certification authorities assessing compliance with European requirements

Adopting EN 14197‑2 helps ensure mechanical integrity, safe operation, and regulatory alignment for static cryogenic vessels used in industry.
