Cryogenic vessels - Methods for performance evaluation of thermal insulation

This standard defines a pratical method for determining the heat leak performance of cryogenic vessels. The methods include measurement on both open and closed systems. This standard neither specify the requirement levels for insulation performance nor when the methodology defined is applied. These requirements may be defined in design or operational standards/regulations.

Diese vorliegenden Norm legt, ein in der Praxis anwendbares Verfahren zur Bestimmung des Wärmedämmvermögens von Kryo-Behältern. Das Verfahren umfaßt sowohl Messungen an offenen als auch an geschlossenen Systemen. Diese Norm legt weder Anforderungsstufen für das Wärmedämmvermögen fest, noch wenn die festgelegte Methodologie angewendet wird. Diese Anforderungen können in den Normen/Regeln über Konstruktion und Betrieb angegeben werden.

Récipients cryogéniques - Méthodes d'évaluation de la performance de l'isolation thermique

La présente norme définit une méthode pratique pour déterminer la performance des récipients cryogéniques en terme d'entrées de chaleur. Les méthodes comprennent des mesures à la fois sur des systèmes ouverts et fermés. La présente norme ne spécifie pas ni les niveaux d'exigence de la performance de l'isolation des récipients cryogéniques ni quand la méthode définie dans cette norme est utilisée. Ces exigences peuvent être définies dans les normes/règlements de conception et de fonctionnement.

Overview

EN 12213:1998 - "Cryogenic vessels - Methods for performance evaluation of thermal insulation" (CEN) defines a practical, standardized approach to measuring the heat leak and insulation performance of cryogenic vessels. The standard covers test methods applicable to both open and closed systems and focuses on how to evaluate thermal insulation effectiveness. EN 12213 describes measurement methodology and reporting requirements but does not set pass/fail insulation performance levels or prescribe when the method must be applied; those thresholds belong to design or operational standards and regulations.

Key topics

The standard addresses the practical elements required to evaluate cryogenic thermal insulation performance, including:

• Scope and applicability of the evaluation methods for different vessel types (open vs. closed)
• Measurement procedures for determining heat leak and thermal losses during steady and transient conditions
• Test setup and instrumentation guidance (sensors, data acquisition, calibration practices)
• Data analysis and calculation approaches for converting test data into heat leak or thermal performance figures
• Reporting and documentation requirements to ensure reproducible, auditable results
• Considerations for test conditions, safety and repeatability

Note: EN 12213 provides methods and procedures only - it does not specify numerical insulation performance limits or certification criteria.

Applications

EN 12213 is a practical resource for professionals who need to quantify insulation performance of cryogenic vessels or compare insulation solutions:

• Manufacturers of cryogenic tanks, dewars and transport vessels for validating insulation design and quality control
• Test laboratories and research facilities conducting standardized cryogenic insulation testing
• Design engineers assessing heat leak estimates for thermal modelling and system sizing
• Maintenance and inspection teams verifying in-service insulation degradation or retrofit effectiveness
• Regulators and procurement specialists who need consistent test data to reference in contracts or compliance documents

Keywords: EN 12213, cryogenic vessels, thermal insulation, heat leak performance, cryogenic insulation testing, open and closed systems.

Related standards

EN 12213 supplies test methodology but not performance criteria - users should consult relevant design standards, operational regulations, and safety codes that define allowable heat leak rates or insulation performance requirements for specific applications.
