Standard

ISO 26142:2010 defines the performance requirements and test methods of hydrogen detection apparatus that is designed to measure and monitor hydrogen concentrations in stationary applications. The provisions in ISO 26142:2010 cover the hydrogen detection apparatus used to achieve the single and/or multilevel safety operations, such as nitrogen purging or ventilation and/or system shut-off corresponding to the hydrogen concentration. The requirements applicable to the overall safety system, as well as the installation requirements of such apparatus, are excluded. ISO 26142:2010 sets out only the requirements applicable to a product standard for hydrogen detection apparatus, such as precision, response time, stability, measuring range, selectivity and poisoning. ISO 26142:2010 is intended to be used for certification purposes.

ISO 23274-2 specifies a chassis dynamometer test procedure to determine the end of CD (charge-depleting) state and consumed electric energy during CD state. The identification of the end of CD state is an important step for procedures to determine exhaust emissions and fuel consumption. Final determination of exhaust emissions and fuel consumption is not included in ISO 23274-2. ISO 23274-2:2012 applies to vehicles with the following characteristics. The vehicles are hybrid-electric road vehicles (HEV) with an internal combustion engine (ICE) and the on-board rechargeable energy storage system (RESS) for vehicle propulsion which is supplied by electric energy from the stationary external power source. A CD state, in which the electric energy in RESS from the stationary external power source is consumed, is followed by a CS (charge-sustaining) state in which the fuel energy is consumed sustaining the electric energy of the RESS. Only batteries are assumed as the RESS of a vehicle. The RESS is not charged while driving unless by regenerative braking and/or by generating by ICE. The vehicle is classified as a passenger car or light duty truck, as defined in each regional annex.
Only liquid fuels (for example, gasoline and diesel fuel) are used. Trolleybuses and solar powered vehicles are not included in the scope. In the case of vehicles with ICE using other fuel [for example, compressed natural gas (CNG), hydrogen (H2)], ISO 23274-2:2012 can apply except the measurement of consumed fuel; otherwise the measurement method for those using the corresponding fuel can apply.

This document specifies a chassis dynamometer test procedure to measure the exhaust emissions and the electric energy and fuel consumption for the vehicles. This document applies to vehicles with the following characteristics:
— vehicles classified as passenger cars or light duty trucks, as defined in the relevant regional applicable driving test (ADT) standard;
— the nominal energy of the rechargeable energy storage system (RESS) is at least 2 % of the total energy consumption over an ADT;
— internal combustion engine (ICE) only using liquid fuels (for example, gasoline and diesel fuel).
NOTE In the case of the vehicles with ICE using other fuel [for example, compressed natural gas (CNG), liquefied petroleum gas (LPG), hydrogen], this document can apply except the measurement of consumed fuel; otherwise the measurement method for those using the corresponding fuel can apply.
This document proposes procedures for correcting the measured emissions and fuel consumption of hybrid-electric vehicles (HEVs), in order to obtain the values when the state of charge (SOC) of the RESS does not remain the same between the beginning and the end of an ADT.
It can also be applied to measurement procedures for exhaust emissions and fuel consumption of externally chargeable HEVs when a vehicle is not externally charged and operated only in the charge sustaining (CS) state, as described in ISO 23274‑2.

ISO 23181:2007 specifies a method for determining the resistance of a hydraulic filter element to flow fatigue when subjected to high viscosity fluid, using a uniformly varying flow rate up to a predetermined terminal differential pressure and a controlled waveform.

It establishes a method for verifying the ability of a filter element to withstand the flexing caused by cyclic differential pressures induced by a variable flow rate.

This document defines the construction, safety, and performance requirements of modular or factory-matched hydrogen gas generation appliances, herein referred to as hydrogen generators, using electrochemical reactions to electrolyse water to produce hydrogen. This document is applicable to hydrogen generators that use the following types of ion transport medium: group of aqueous bases; group of aqueous acids; solid polymeric materials with acidic function group additions, such as acid proton exchange membrane (PEM); solid polymeric materials with basic function group additions, such as anion exchange membrane (AEM). This document is applicable to hydrogen generators intended for industrial and commercial uses, and indoor and outdoor residential use in sheltered areas, such as car-ports, garages, utility rooms and similar areas of a residence. Hydrogen generators that can also be used to generate electricity, such as reversible fuel cells, are excluded from the scope of this document. Residential hydrogen generators that also supply oxygen as a product are excluded from the scope of this document.

ISO 21789:2009 covers the safety requirements for gas turbine applications using liquid or gaseous fuels and the safety-related control and detection systems and essential auxiliaries for all types of open cycles (simple, combined, regenerative, reheat, etc.) used in onshore and offshore applications including floating production platforms. It applies to driven machinery only where an integral part of the gas turbine (e.g. a gearbox integral to the gas turbine) or located within the gas turbine enclosure and forming part of the enclosure hazardous area classification (e.g. a generator within the gas turbine enclosure), or where the driven machinery has a direct effect on the operational safety of the gas turbine. It details the anticipated significant hazards associated with gas turbines and specifies the appropriate preventative measures and processes for reduction or elimination of these hazards. It addresses the risks of injury or death to humans and risks to the environment. Equipment damage without risk to humans or the environment is not covered. It excludes gas turbines used primarily for direct and indirect propulsion, special heat source applications and in research and development programmes. It also excludes gas turbines for closed-cycle and semi-closed cycle applications, and compressed-air energy storage plants. Where appropriate, it can be used to give general guidance in such applications. It is not applicable to machinery or safety components that were manufactured before the date of its publication.
