General Information
Frequently Asked Questions
ICS 23.020 is a classification code in the International Classification for Standards (ICS) system. It covers "Fluid storage devices". The ICS is a hierarchical classification system used to organize international, regional, and national standards, facilitating the search and identification of standards across different fields.
There are 2167 standards classified under ICS 23.020 (Fluid storage devices). These standards are published by international and regional standardization bodies including ISO, IEC, CEN, CENELEC, and ETSI.
The International Classification for Standards (ICS) is a hierarchical classification system maintained by ISO to organize standards and related documents. It uses a three-level structure with field (2 digits), group (3 digits), and sub-group (2 digits) codes. The ICS helps users find standards by subject area and enables statistical analysis of standards development activities.

- rack frame/structure;
- rack closures;
- rack fixing equipment or accessories on to the vehicle.
This document applies to checks performed:
- at cylinder filling plants and depots;
- or at cylinder manufacturing and/or refurbishment facilities;
- or at any place where racks are used or moved.
This document also provides guidance and examples for rack maintenance and repair procedures, including rejection criteria and for establishing operational procedures. Transportation racks are also called stillages, pallets or racks (see Clause 3).
This document does not cover the design and the manufacturing of racks.
This document does not apply to presentation display racks at points of sale.

This document specifies equipment and accessories for road tankers used for the transport of Liquefied Petroleum Gas (LPG) and identifies the equipment that is considered necessary to ensure that filling, transportation and discharge operations can be carried out safely. It specifies the requirements for the assembly of the accessories and the vehicle LPG equipment to the road tanker. This document also identifies additional equipment and accessories that can be used on road tankers carrying LPG.
This document does not preclude the use of alternative designs, materials and equipment testing which provide the same or a higher level of safety. ADR [9] requires that such alternative technical codes be recognized by the competent authority, provided that the minimum requirements of section 6.8.2 of ADR [9] are complied with.
This document does not apply to “tank-containers” or “battery-vehicles” used for the transport of LPG.

This document is applicable to the design and manufacture of site built, vertical, cylindrical, flat-bottomed tank systems for the storage of refrigerated, liquefied gases with operating temperatures between 0 °C and –196°C. It specifies the requirements for testing, drying, purging, cool-down and decommissioning of refrigerated liquefied gas storage tank systems.
The tank systems covered by this document are used to store large volumes of hydrocarbon products, ammonia and other non-hydrocarbon gases with low temperature boiling points, generally called “Refrigerated Liquefied Gases” (RLGs). Typical products stored in the tank systems are: methane, ethane, propane, butane, ethylene, propylene, butadiene (this range includes Liquefied Natural Gas (LNG) and Liquefied Petroleum Gas (LPG), ammonia, nitrogen, oxygen and argon.
NOTE Properties of the gases are given in Annex A EN 14620-1:2024.
This document provides requirements and specifies measures to be taken following completion of major tank construction activities and before the tank is brought in to service. It provides requirements for full-height and partial height hydrostatic testing to check the structural integrity of tanks and the capacity of the foundations. Settlement monitoring of the foundations at this stage form the starting point of an annual settlement monitoring programme for the tank foundation. Recommendations are given for marker systems for such monitoring. Requirements for water quality of both fresh water and seawater used during hydrotest, are provided to avoid the risk of corrosion of tanks and appurtenances.
Guidance and requirements for positive and negative pneumatic tests to further check tank structural integrity, leak tightness of welds and the function of pressure and vacuum relief valve systems are also given. Requirements specific to testing of double wall and membrane type tanks is included.
Rules and procedures for commissioning activities, including drying and purging with inert and product gas are provided, including required oxygen concentrations for various RLG’s. The document also provides guidance for cool-down procedures and suggestions for temperature monitoring, including an informative Annex A.
For major maintenance inspection or at the end of the life of the tank, decommissioning will be required. Guidance on safe decommissioning processes is provided.
Suggested procedures for Global testing for membrane tanks are provided in informative Annex B
This document is applicable to the design and manufacture of site built, vertical, cylindrical, flat-bottomed tank systems for the storage of refrigerated, liquefied gases with operating temperatures between 0 °C and -196°C.

This document specifies the procedures to be followed when connecting cylinder valves to gas cylinders. It specifically applies to all valve and cylinder combinations connected with ISO screw threads as specified in ISO 11363-1 and ISO 15245-1. It defines procedures and practices for inspection and preparation prior to valving for both taper and parallel screw threads.
Torque values are given in Annex A for steel and aluminium alloy gas cylinders including composite cylinders with steel or aluminium alloy neck boss.
NOTE The procedures and practices specified in this document can be beneficially applied to other valve to cylinder screw thread connection systems. ISO/TR 11364 lists the valve to gas cylinder threads in use worldwide. It gives details of the thread identification codes, whether the threads are interchangeable with ISO threads and if the taping procedure and torque values specified in this document can be used. ISO/TR 11364 gives clear guidance for the method and torque for all listed inlet threads, which are not interchangeable.
