Hydrogen technologies - Methodology for determining the greenhouse gas emissions associated with the hydrogen supply chain - Part 1: Emissions associated with the production of hydrogen to production gate (ISO/DIS 19870-1:2025)

ISO 14044 requires the goal and scope of an LCA to be clearly defined and be consistent with the intended application. Due to the iterative nature of LCA, it is possible that the LCA scope needs to be refined during the study. This document specifies methodologies that can be applied to determine the carbon footprint of a product (CFP) or partial CFP of a hydrogen product in line with ISO 14067. The goals and scopes of the methodologies correspond to either approach a) or b), given below, that ISO 14040:2006, A.2 gives as two possible approaches to LCA. a) An approach that assigns elementary flows and potential environmental impacts to a specific product system, typically as an account of the history of the product. b) An approach that studies the environmental consequences of possible (future) changes between alternative product systems. Approaches a) and b) have become known as attributional and consequential, respectively, with complementary information accessible in the ILCD handbook.[1] There are numerous pathways to produce hydrogen from various primary energy sources. This document describes the requirements and evaluation methods applied to several hydrogen production pathways of interest: electrolysis, steam methane reforming (with carbon capture and storage), co-production and coal gasification (with carbon capture and storage), auto-thermal reforming (with carbon capture and storage), hydrogen as a co-product in industrial applications and hydrogen from biomass waste as feedstock. This document also considers the GHG emissions due to the conditioning or conversion of hydrogen into different physical forms and chemical carriers: — hydrogen liquefaction; — production, transport and cracking of ammonia as a hydrogen carrier; — hydrogenation, transport and dehydrogenation of liquid organic hydrogen carriers (LOHCs). This document considers the GHG emissions due to hydrogen and/or hydrogen carriers’ transport up to the consumption gate. It is possible that future revisions of this document will consider additional hydrogen production, conditioning, conversion and transport methods. This document applies to and includes every delivery along the supply chain up to the final delivery to the consumption gate (see Figure 2 in the Introduction). This document also provides additional information related to evaluation principles, system boundaries and expected reported metrics in the form of Annexes A to K, that are accessible via the online ISO portal (https://standards.iso.org/iso/ts/19870/ed-1/en).

Portable fire extinguishers - Part 7: Characteristics, performance requirements and test methods

This document specifies the characteristics, performance requirements and test methods for portable fire extinguishers. Reference to the suitability of an extinguisher for use on gaseous fires (Class C fires) are at the manufacturer’s discretion but are applied only to powder type extinguishers which have gained a Class B or Class A and Class B rating. Suitability of extinguishers for use on Class D fires (fires involving flammable metals) is outside the scope of this document in respect of test fires. However, extinguishers claiming Class D suitability are covered in all other respects by the requirements in this document for powder extinguishers. It is considered hazardous for powder and carbon dioxide fire extinguishers to be used on Class F fires. For this reason, powder and carbon dioxide fire extinguishers are excluded for conformance with regard to Class F in this document. NOTE The extinction of a metal fire presents a situation so specific (in terms of the metal itself, its form, the configuration of the fire etc.) that it is not possible to define a representative standard fire for the purposes of testing. The efficiency of extinguishers on Class D fires is established on a case by case basis.

Explosion isolation flap valves

This European Standard describes the general requirements for flap valves used for dust explosion isolation. An explosion isolation flap valve is a protective system, which prevents a dust explosion from propagating via connecting pipes or ducts into other parts of apparatus or plant areas. An explosion isolation flap valve can only stop the propagation of a dust explosion when it propagates against the direction of the normal process flow. It does not stop explosions running in the normal process flow direction. This European Standard specifies methods for evaluating the efficacy of explosion isolation flap valves. This European Standard is applicable only to the use of explosion isolation flap valves that are intended for avoiding explosion propagation from a vessel, into other parts of the installation via connecting pipes or ducts. The standard covers isolation of such vessels that are protected by explosion venting (including flameless venting), explosion suppression or explosion resistant design. NOTE 1 The standard assumes that the explosion starts in a vessel and not in ducting. Explosion isolation flap valves are not designed to prevent the transmission of fire or burning powder transported by the normal process flow. NOTE 2 It is necessary to take this into account in risk assessments. This European Standard is only applicable for dust explosions. This European Standard is not applicable for explosions of materials listed below, or for mixtures containing some of those materials: a) gases, vapours and hybrid mixtures; b) chemically unstable substances; c) explosive substances; d) pyrotechnic substances.

Explosive atmospheres - Part 41: Reciprocating internal combustion engines (ISO/IEC DIS 80079-41:2025)

This part of ISO/IEC 80079 specifies the technical requirements for design, construction, conversion, testing, marking and the information required for use to avoid or minimise the possibility of ignition which could from reciprocating internal combustion engine intended for use in explosive atmospheres including: – Group I EPL Mb for use in underground workings susceptible to firedamp or combustible dust, – Group II EPL Gb and EPL Gc for use in explosive atmospheres of flammable gas and vapour, and – Group III EPL Db and EPL Dc for use in explosive atmospheres of combustible dust. – For EPL Gc and Dc engines, only normal operating conditions need to be taken into account. Malfunctions need not be considered (see B.2.1). This document includes those tests of the engine and its ancillary devices that are required to verify compliance with this document. This document applies to both reciprocating internal combustion engines with compression ignition for EPL Mb, Gb, Gc, Db, Dc and gaseous fuelled spark ignition engines for EPL Gc. See Annex G. This document does not define requirements relating to the driven machinery and equipment. This document does not apply to – explosive mixtures of vapours and gases, which tend to self-decompose (for example carbon disulphide (CS2), ethylene oxide (C2H4O), acetylene (C2H2)) or which are chemically unstable; • hydrogen fueled engines, including blends; • engines used in areas for the processing, manufacture or storage of explosives; • gasoline and other spark ignited engines where the fuel is injected into the combustion chamber as a liquid; or • electrical ignition spark systems. Note 1 Spark ignition systems used with equipment covered by ISO/IEC 80079-41 is covered by IEC 60079-45 This document solely deals with explosion protection requirements. Requirements on gaseous or particulate exhaust emissions are not covered by this standard. General safety requirements are not included in this International Standard. This document does not specify requirements for safety, other than those directly related to the possibility of ignition of flammable mixtures in the surrounding atmosphere which can lead to an explosion. The standard atmospheric conditions (relating to the explosion characteristics of the atmosphere) under which it can be assumed that the engine may be operated are: • temperature –20 °C to +60 °C • pressure 80 kPa (0,8 bar) to 110 kPa (1,1 bar); and • air with normal oxygen content, typically 21% v/v. An engine for use outside of the standard atmospheric conditions is to be designed, constructed tested and marked for those conditions. The ignition hazard assessment, ignition, protection provided, additional testing (if necessary) manufacturer’s technical documentation and instructions to the user are intended toclearly demonstrate the engine’s suitability for the conditions. NOTE 2 changes in temperature and pressure have an influence on the characteristics of the explosive atmosphere including ignitability NOTE 3 IEC TS 60079-43 gives information for equipment used in explosive atmospheres in environmental conditions which include ambient temperatures below –20 °C and additional adverse conditions, including maritime applications. NOTE 4 Reciprocating internal combustion engines are not considered as pressure vessels. This document supplements and modifies the general requirements of IEC 60079-0:2017 and ISO 80079-36. Where a requirement of this document conflicts with a requirement of IEC 60079-0:2017 and ISO 80079-36 as far as applicable for Ex engines, the requirement of this standard takes precedence. NOTE 5 On-going inspection, maintenance and repair aspects play an important role in control of hazardous area installations and the user’s attention is drawn to IEC 60079-17, IEC 60079-19 and IEC 60079-14 and manufacturer’s instructions for further information concerning these aspects.
