This document specifies the requirements for the design, manufacture and testing of non‑reclosable pressure-relief devices for cryogenic service, i.e. for operation with cryogenic fluids in addition to operation at temperatures from ambient to cryogenic. This document is restricted to bursting‑disc and buckling‑pin devices not exceeding a nominal diameter size (DN) of 200 that are designed to relieve single‑phase vapours or gases. A bursting‑disc or buckling‑pin assembly can be specified, constructed and tested such that it is suitable for use with more than one gas or with mixtures of gases. NOTE This document does not provide methods for determining the capacity of bursting‑disc or buckling‑pin devices for a particular cryogenic vessel. Such methods are provided in ISO 21013-3.

This document describes a method for determining the resistance of a cryogenic spill protection (CSP) system to a cryogenic jet as a result of a pressurized release which does not result in immersion conditions. It is applicable where CSP systems are installed on carbon steel and will be in contact with cryogenic fluids.
A cryogenic jet can be formed upon release from process equipment operating at pressure (e.g. some liquefaction processes utilize 40 to 60 bar operating pressure). Due to high pressure discharge, the cryogenic spillage protection can be compromised by the large momentum combined with extreme cryogenic temperature.
Although the test uses liquid nitrogen as the cryogenic liquid, the test described in this document is representative of a release of LNG, through a 20 mm orifice or less, at a release pressure of 6 barg or less, based upon simulated parameters 1 m from the release point. Confidence in this test being representative is based upon a comparison of the expected dynamic pressure of the simulated release in comparison with dynamic pressure from releases in accordance with this document.
It is not practical in this test to cover the whole range of cryogenic process conditions found in real plant conditions; in particular the test does not cover high pressure cryogenic jet releases that might be found in refrigeration circuits and in LNG streams immediately post-liquefaction.
Liquid nitrogen is used as the cryogenic medium due to the ability to safely handle the material at the pressures described in this document. The test condition is run at nominally 8 barg pressure.
ISO 20088-1 covers cryogenic release scenarios which can lead to pooling conditions for steel work protected by cryogenic spill protection as a result of a jet release or low pressure release of LNG or liquid nitrogen. ISO 20088-2 covers vapour phase exposure conditions as a result of a jet release or low pressure release of LNG or liquid nitrogen.

ISO 21012:2018 specifies design, construction, type and production testing, and marking requirements for non-insulated cryogenic flexible hoses used for the transfer of cryogenic fluids within the following range of operating conditions: - working temperature: from −270 °C to +65 °C; - nominal size (DN): from 10 to 100. End fittings for mounting of any couplings are within the scope of this document, but the couplings are subject to other standards. ISO 21012:2018 is intended that the hose be designed and tested to satisfy the generally accepted rated pressure i.e. at least PR 40.

ISO 20088-1:2016 describes a method for determining the resistance to liquid cryogenic spillage on cryogenic spillage protection (CSP) systems. It is applicable where CSP systems are installed on carbon steel and will be in contact with cryogenic fluids.
Liquid nitrogen is used as the cryogenic medium since it has a lower boiling point than liquid natural gas or liquid oxygen and it is not flammable. Additionally, it can be safely used for experiment.
Future parts of the standard will cover vapour phase and jet exposure conditions.
The test laboratory is responsible to conduct an appropriate risk assessment according to local regulation in order to consider the impact of liquid and gaseous nitrogen exposure to equipment and personnel.

ISO 21029-2:2015 specifies operational requirements for transportable vacuum insulated cryogenic vessels of not more than 1 000 l volume designed to operate above atmospheric pressure. Appropriate parts may be used as a guidance for a vessel design to operate open to the atmosphere.
For cryogenic vessels designed for personal medical use, other requirements can apply.
The scope includes putting into service, filling, withdrawal, transport within the location, storage, maintenance, periodic inspection, and emergency procedures.
For the transportation of these vessels by public road, rail, sea, and air, other additional requirements can apply; these are defined in specific regulations.
Transportable cryogenic vessels of not more than 1 000 l volume are often partly equipped by the manufacturer, but can be installed or re-installed by another party, such as the operator or owner. For this reason, some of the scope of ISO 21029-2:2015, which includes putting into service, inspection, filling, maintenance, and emergency procedure, overlaps with ISO 21029‑1.

However, it can be applied to other types of cryogenic pumps (e.g. reciprocating pumps), where applicable. This International Standard also gives guidance on the design of installations (see Annex A). It does not specify requirements for operation or maintenance.

ISO 21009-2:2015 specifies operational requirements for static vacuum insulated vessels designed for a maximum allowable pressure of more than 50 kPa (0,5 bar). It may also be used as a guideline for vessels designed for a maximum allowable pressure of less than 50 kPa (0,5 bar). ISO 21009-2:2015 applies to vessels designed for cryogenic fluids specified in ISO 21009‑1. Static cryogenic vessels are often partly equipped by the manufacturer, but may be installed or re-installed by another party, such as the operator, user or owner. NOTE 1 For the installation of these vessels, additional requirements can apply; these are defined in specific regulations. NOTE 2 Some requirements of this standard can be covered by local regulations, e.g. safety distances, occupational safety and health. Where there is a conflict between the requirements of this International Standard and any applicable local regulation, the local regulation always takes precedence.
