Cryogenic vessels - Transportable vacuum insulated vessels of not more than 1000 litres volume - Part 1: Fundamental requirements
This standard specifies the fundamental requirements for transportable vacuum insulated cryogenic vessels of not more than 1000 litres volume and designed to operate above atmospheric pressure. Appropriate parts may be used as a guidance for vessels designed to operate to the atmosphere. This standard applies to transportable vacuum insulated cryogenic vessels for fluids as specified in 3.1 and is not applicable to such vessels designed for toxic fluids.
Kryo-Behälter - Orstbewegliche, vakuumisolierte Behälter mit einem Fassungsraum von nicht mehr als 1000 Liter - Teil 1: Grundanforderungen
Diese Norm legt die Grundanforderungen für ortsbewegliche vakuum-isolierte Kryo-Behälter mit einem Fassungsraum von nicht mehr als 1000 Litern fest, die für einen Betrieb über Atmosphärendruck ausgelegt sind. Diese Norm gilt für ortsbewegliche vakuum-isolierte Kryo-Behälter für Fluide, wie in 3.1 definiert, und nicht für solche, die für Fluide ausgelegt sind.
Récipients cryogéniques - Récipients transportables, isolés sous vide, d'un volume n'excédant pas 1000 litres - Partie 1: Exigences fondamentales
La présente norme spécifie les exigences fondamentales relatives à des récipients cryogéniques transportables, isolés sous vide, d'un volume n'excédant pas 1000 litres et conçus pour opérer à une pression supérieure à la pression atmosphérique. Les parties appropriées peuvent être utilisées comme guide pour les récipients conçus pour opérer à pression atmosphérique. La présente norme s'applique aux récipients cryogéniques transportables, isolés sous vide, pour des fluides tels que spécifiés en 3.1 et n'est pas applicable à des récipients prévus pour contenir des fluides toxiques.

Overview
EN 1251-1:2000 (CEN) specifies the fundamental requirements for transportable, vacuum‑insulated cryogenic vessels with a maximum internal volume of 1000 litres that are designed to operate above atmospheric pressure. The standard is focused on transportable cryogenic vessels for the fluids identified in section 3.1 of the document and expressly excludes vessels intended for toxic fluids. National adoptions exist (example: SIST EN 1251‑1:2001).
Keywords: EN 1251-1:2000, cryogenic vessels, transportable vacuum insulated vessels, 1000 litres, fundamental requirements, CEN.
Key Topics
The standard establishes baseline requirements and guidance for aspects of transportable cryogenic vessels, including:
- Scope and applicability - transportable vacuum‑insulated vessels ≤1000 L designed to operate above atmospheric pressure; exclusion of toxic‑fluid applications; reference to fluids specified in section 3.1.
- Design limits - volume and pressure boundaries that define applicability (≤1000 litres; operation above atmospheric pressure).
- Insulation and vacuum integrity - requirements related to vacuum insulation as the thermal protection method for cryogenic temperatures.
- Safety and exclusion criteria - exclusion of vessels for toxic fluids; guidance applicability for vessels designed to operate at atmospheric pressure via appropriate parts.
- Conformity and national adoption - the document is a CEN standard that may be adopted as a national standard (e.g., SIST EN 1251‑1:2001).
(Note: EN 1251‑1:2000 sets fundamental requirements; detailed clauses such as testing regimes or specific material lists are contained in the full text and related parts.)
Applications
EN 1251‑1:2000 is relevant for organizations involved with the manufacture, handling and transport of non‑toxic cryogenic fluids in portable vessels:
- Manufacturers and designers of transportable vacuum‑insulated cryogenic containers (≤1000 L)
- Quality and compliance engineers ensuring products meet CEN fundamental requirements
- Transport and logistics companies that move cryogenic vessels and need to verify vessel classification
- Procurement teams specifying compliant cryogenic equipment
- Standards and regulatory auditors assessing conformity with European technical requirements
Common use cases include small portable liquid gas cylinders and dewars for medical gases, research laboratories, and industrial applications where vacuum insulation and pressurized operation are required.
Related Standards
