Full title and description

ISO 21014:2019/Amd 1:2022 — Cryogenic vessels — Cryogenic insulation performance — Amendment 1. This amendment updates and clarifies aspects of the test and measurement methods used to determine the heat‑leak (insulation) performance of cryogenic vessels, as specified in ISO 21014:2019.

Abstract

ISO 21014:2019 defines practical methods for determining the heat‑leak (insulation) performance of cryogenic vessels, covering measurement procedures for both open and closed systems and guidance on test execution and results reporting. Amendment 1 (published August 2022) provides targeted technical clarifications and editorial corrections to the 2019 edition to ensure clearer application of the measurement methods.

Scope

This document specifies practical test methods to determine the heat‑leak (insulation) performance of cryogenic vessels. It describes measurement techniques applicable to both open systems (where boil‑off or venting occurs) and closed systems, gives guidance on test apparatus and procedures, and sets out reporting requirements for measured performance. The standard does not set pass/fail insulation performance limits or prescribe when the methods must be applied; it provides the measurement methodology. Amendment 1 supplies clarifications and small technical adjustments to the original 2019 text.

Key topics and requirements

• Definition of heat‑leak / insulation performance metrics for cryogenic vessels.
• Test methods for measuring heat leak on open systems (boil‑off / mass loss measurement).
• Test methods for closed systems (instrumentation, thermal balance and calorimetric approaches).
• Requirements for test instrumentation, data collection, uncertainty considerations and environmental conditions.
• Reporting formats and information required to demonstrate and compare insulation performance.

Typical use and users

Used by cryogenic‑vessel manufacturers, test laboratories, certifiers, designers and operators in industries that handle cryogenic fluids (industrial gases, LNG, aerospace, research laboratories). The standard supports product development, type testing, quality control and acceptance testing where validated insulation performance measurements are required.

Related standards

ISO 21014 is part of the ISO/TC 220 family covering cryogenic vessels. Related standards include ISO 21009 (static vacuum‑insulated vessels), ISO 21010 (gas/material compatibility), ISO 21013 (pressure‑relief accessories) and ISO 20421 (large transportable vacuum‑insulated vessels), among others addressing design, testing and operational requirements for cryogenic equipment.

FAQ

Q: What is this standard?

A: ISO 21014:2019 is an international standard that defines practical methods to measure the insulation (heat‑leak) performance of cryogenic vessels; the referenced document here is Amendment 1 published in August 2022 which updates/clarifies parts of the 2019 edition.

Q: What does it cover?

A: It covers measurement techniques and procedures for determining heat‑leak on both open and closed cryogenic vessels, instrumentation and data reporting. It does not prescribe acceptance criteria or minimum performance levels — it standardizes the measurement method. The amendment provides targeted clarifications to the original methods text.

Q: Who typically uses it?

A: Manufacturers, independent test laboratories, certification bodies, end‑users/operators of cryogenic storage and transport equipment, and engineers developing or validating vessel insulation systems.

Q: Is it current or superseded?

A: ISO 21014:2019 remains the current published standard for insulation‑performance measurement; Amendment 1 (published 29 August 2022) is an active published amendment to that edition. For the authoritative text and exact amendment wording purchase the ISO documents or obtain them from your national standards body.

Q: Is it part of a series?

A: Yes — it is part of the ISO/TC 220 (Cryogenic vessels) family of standards (ISO 21009, ISO 21010, ISO 21013 series, ISO 20421 series, etc.) that together address design, testing, operational requirements and accessories for cryogenic equipment.

Q: What are the key keywords?

A: Cryogenic vessels, insulation performance, heat leak, boil‑off, thermal testing, measurement methods, ISO 21014, amendment 2022.
