Kryo-Behälter - Ortsbewegliche, vakuumisolierte Behälter mit einem Fassungsraum von nicht mehr als 1000 Liter - Teil 2: Bemessung, Herstellung und Prüfung
Diese Europäische Norm gilt für die Bemessung, Herstellung und Prüfung von ortsbeweglichen, vakuum-isolierten Kryo-Behältern mit einem Fassungsraum von nicht mehr als 1000 Litern, die für einen höchstzulässigen Betriebsdruck über Atmosphärendruck bemessen sind. Diese Norm gilt für ortsbewegliche, vakuum-isolierte Kryo-Behälter für Fluide, die in EN 1251 festgelegt, und sie gilt nicht für giftige Fluide.
Récipients cryogéniques - Récipients transportables, isolés sous vide, d'un volume n'excédant pas 1000 litres - Partie 2: Conception, fabrication, inspection et essai
La présente norme européenne est applicable à la conception, à la fabrication, aux contrôles et aux essais des récipients cryogéniques transportables, isolés sous vide, d'un volume n'excédant pas 1000 litres, et conçus pour une pression maximale admissible supérieure à la pression atmosphérique. La présente norme s'applique aux récipients cryogéniques transportables, isolés sous vide, pour les fluides, tels que spécifiés dans l'EN 1251-1 et ne s'applique pas à des récipients prévus pour contenir des fluides toxiques.

Overview
EN 1251-2:2000 is a European Standard published by CEN that specifies requirements for transportable vacuum insulated cryogenic vessels with a capacity of not more than 1000 litres. The standard covers the design, fabrication, inspection and testing of these vacuum‑insulated vessels when they are designed for a maximum allowable pressure greater than atmospheric. EN 1251-2 applies to vessels intended for the fluids listed in prEN 1251-1 and explicitly excludes vessels designed for toxic fluids.
Key Topics
- Scope and applicability: Limits on vessel volume (≤1000 L) and pressure class (greater than atmospheric); exclusion of toxic-fluid vessels.
- Design requirements: Principles for safe structural design and material selection appropriate for vacuum‑insulated, transportable cryogenic equipment (as defined in the standard).
- Fabrication and welding: Requirements for manufacturing processes and quality control during assembly and joining of cryogenic vessel components.
- Inspection and testing: Mandatory inspection regimes and testing procedures to verify integrity, vacuum insulation performance and pressure containment before and after commissioning.
- Documentation and marking: Requirements for technical documentation, records of inspections/tests, and marking to demonstrate compliance.
Applications
EN 1251-2 is used to ensure safety, reliability and regulatory compliance for small transportable cryogenic containers. Typical practical applications include:
- Manufacturing and certification of transportable vacuum insulated vessels used to store and transport non-toxic cryogenic fluids.
- Quality assurance and inspection planning by fabricators and testing laboratories.
- Procurement and technical specifications for industrial gas suppliers, research facilities, laboratories and maintenance organizations that deploy transportable cryogenic containers.
- Reference for safety engineers, compliance officers and certifying bodies assessing vessel conformity with European design and testing expectations.
Who Should Use This Standard
- Manufacturers and designers of transportable cryogenic vessels
- Welding and fabrication workshops producing vacuum-insulated containers
- Inspection bodies and testing laboratories performing compliance verification
- Procurement teams and end users specifying or operating non-toxic cryogenic vessels
Related Standards
- prEN 1251-1 - defines the fluids and related baseline requirements (referenced by EN 1251-2)
- Other European and national pressure-vessel and cryogenic standards (for broader conformity and regulatory alignment)
EN 1251-2:2000 is essential for professionals involved in the lifecycle of small, transportable vacuum insulated cryogenic vessels who need to meet consistent European requirements for design, fabrication, inspection and testing.
