This part of ISO 10094 specifies which characteristics of electro-pneumatic continuous pressure control valves are to be included in the supplier's literature.

In accordance with ISO 5598, these control valves include

— electrically modulated pneumatic proportional pressure valves,

— proportional pressure control valves without electronic pressure feedback, and

— proportional pressure control valves with electronic pressure feedback.

NOTE 1 The characteristics of non-electrically modulated pneumatic pressure control valves are specified in ISO 6953-1.

NOTE 2 The characteristics of electro-pneumatic continuous flow control valves are specified in ISO 10041-1.

NOTE 3 This part of ISO 10094 is limited to the characterization of components with an exhaust port to the atmosphere.

This document specifies the requirements for valve protection caps, valve guards and shrouds used on cylinders for liquefied, dissolved or compressed gases.

Valve protection caps, valve guards or shrouds are some of the options available to protect cylinder valves (including Valves with Integral Pressure Regulators, abbreviated VIPRs) during transport.

While this document is applicable to valve protection caps, valve guards and shrouds which inherently provide the primary protection of a cylinder valve, it might also be beneficially used to test other equipment attached to cylinder packages, even in cases where the cylinder valve is inherently able to withstand damage without release of the content.

NOTE Small cylinders (e.g. medical) are commonly transported in an outer-packaging (e.g. pallet) to meet transport regulations.

This document does not specify requirements that might be necessary to enable the valve protection device to be used for lifting the cylinder.

This document specifies the requirements for the design, construction, testing and initial inspection of a transportable cylinder bundle.

It is applicable to cylinder bundles containing cylinders or tubes not exceeding a water capacity of 450 l containing compressed gas, liquefied gas and mixtures thereof. Additional requirements for acetylene cylinder bundles containing acetylene in a solvent are provided in Annex B. This document does not, however, cover acetylene cylinder bundles with solvent‐free acetylene cylinders.

Unless otherwise stated, individual cylinders or tubes not exceeding a water capacity of 450 l within a cylinder bundle will have to conform to applicable standards for single cylinders or tubes not exceeding a water capacity of 450 l. This document specifies the additional requirements that apply when individual cylinders or tubes not exceeding a water capacity of 450 l are assembled into a bundle.

This document is intended primarily for industrial gases other than liquefied petroleum gas (LPG), but it may also be used for LPG.

This document does not apply to packages in which cylinders or tubes not exceeding a water capacity of 450 l are manifolded together in a frame that is designed to be fixed permanently to a road vehicle, to a railway wagon or to the ground as a customer storage vessel. It also does not apply to cylinder bundles that are designed for use in extreme environmental or operational conditions (e.g. offshore cylinder bundles) when additional and extraordinary requirements are imposed to maintain safety standards, reliability and performance.

NOTE Unless noted by exception, the use of the word "cylinder" in this document refers to both cylinders and tubes.

This document specifies the technical delivery conditions in two test categories for seamless tubes of circular cross section made of austenitic (including creep resisting steel) and austenitic-ferritic stainless steel which are intended for pressure and corrosion resisting purposes at room temperature, at low temperatures or at elevated temperatures.

NOTE Once this standard is published in the Official Journal of the European Union (OJEU) under Directive 2014/68/EC, presumption of conformity to the Essential Safety Requirements (ESR) of Directive 2014/68/EC is limited to technical data of materials in this standard and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied will be done by the designer or manufacturer of the pressure equipment, taking also into account the subsequent manufacturing processes which may affect properties of the base materials.
