This document specifies the performance tests for the motor system designed as a voltage class B electric propulsion system for electrically propelled road vehicles.

This document specifies the test procedures for performance and operating load for voltage class B electric propulsion components (motor, inverter, DC/DC converter) and their combinations (motor system) of electrically propelled road vehicles.This document specifies the terms and definitions used in the ISO 21782 series and general test conditions.

ISO 21648:2008 establishes the design, analysis, material selection and characterization, fabrication, test and inspection of the flywheel module (FM) in a flywheel used for energy storage in space systems. These requirements, when implemented on a flywheel module, will ensure a high level of confidence in achieving safe operation and mission success. With appropriate modifications, ISO 21648:2008 can also be applied to similar devices, such as momentum and reaction wheels and control-moment gyroscopes. The requirements set forth in ISO 21648:2008 are the minimum requirements for flywheel modules in flywheels used in space flight applications. They are specifically applicable to the parts in the flywheel rotor assembly (FRA), including rim, hub and/or shaft and other associated rotating parts, such as the bearings and the motor generator rotor. The requirements are also relevant to the non-rotating parts, such as module housing, main suspension assembly (magnetic or rolling element bearings, superconductor bearings, etc.), motor stator, caging mechanism and sensors within the module housing, and backup bearings, if applicable. However, control and interface electronics are not covered in ISO 21648:2008.

This document applies to voltage class B electric propulsion systems and connected auxiliary electric systems of electrically propelled road vehicles. Additionally, it applies to electric circuits and components in these systems. This document provides specifications of voltage sub-classes related to DC electric circuits. It also provides specifications of characteristics which are relevant for design and operation of systems and components for the voltage sub-classes. This document does not cover electrical safety (see ISO 17409 and the ISO 6469 series).

ISO 21018-1:2008 specifies methods and techniques that are applicable to the monitoring of particulate contamination levels in hydraulic systems. It also describes the relative merits of various techniques so that the correct monitor for a given application can be selected.

The techniques described in ISO 21018-1:2008 are suitable for monitoring the general cleanliness level in hydraulic systems, the progress in flushing operations and support equipment and test rigs.

ISO 21018-1:2008 can also be applicable for other liquids (e.g. lubricants, fuels and process liquids).

This document specifies measurement methods for the maximum system propulsion power of hybrid-electric vehicles (HEV).The results can be compared with the data of internal combustion engine vehicles (ICEV) power measured with the relevant current method. NOTE ISO 1585 and UN Regulation No. 85, for example. This document applies only to the vehicles with the following characteristics:
— HEVs with an internal combustion engine (ICE) and one or more electric motors powered by one or more rechargeable energy storage systems (RESS) for propulsion;
— vehicles classified as passenger cars or light duty trucks.

This document establishes minimum requirements for pressure relief devices intended for use on hydrogen fuelled vehicle fuel containers that comply with ISO 19881, IEC 62282-4-101, ANSI HGV 2, CSA B51 Part 2, EC79/EU406, SAE J2579, or the UN GTR No. 13. The scope of this document is limited to thermally activated pressure relief devices installed on fuel containers used with fuel cell grade hydrogen according to SAE J2719 or ISO 14687 for fuel cell land vehicles, and Grade A or better hydrogen according to ISO 14687 for internal combustion engine land vehicles. This document also contains requirements for thermally activated pressure relief devices acceptable for use on-board light duty vehicles, heavy duty vehicles and industrial powered trucks such as forklifts and other material handling vehicles, as it pertains to UN GTR No. 13. Pressure relief devices designed to comply with this document are intended to be used with high quality hydrogen fuel such as fuel complying with SAE J2719 or ISO 14687 Type 1 Grade D. Pressure relief devices can be of any design or manufacturing method that meets the requirements of this document. This document does not apply to reseating, resealing, or pressure activated devices. Documents which apply to hydrogen fuel vehicles and hydrogen fuel subsystems include IEC 62282- 4- 101, SAE J2578 and SAE J2579. Annex A presents an informative record of recommended fuel container, fuel storage subsystem and vehicle level requirements. The statements in Annex A are intended as recommendations for consideration of inclusion by the organizations and committees developing standards on these sub system and vehicle level standards. Annex B presents a rationale for the design qualification tests in this document.

This document contains requirements for the material, design, manufacture, marking and testing of serially produced, refillable containers intended only for the storage of compressed hydrogen gas for land vehicle operation. These containers: a) are permanently attached to the vehicle, b) have a capacity of up to 1 000 l water capacity, and c) have a nominal working pressure that does not exceed 70 MPa. The scope of this document is limited to fuel containers containing fuel cell grade hydrogen according to ISO 14687 for fuel cell land vehicles and Grade A or better hydrogen as per ISO 14687 for internal combustion engine land vehicles. This document also contains requirements for hydrogen fuel containers acceptable for use on-board light duty vehicles, heavy duty vehicles and industrial powered trucks such as forklifts and other material handling vehicles.

This document defines the minimum design, installation, commissioning, operation, inspection and maintenance requirements, for the safety, and, where appropriate, for the performance of public and non-public fuelling stations that dispense gaseous hydrogen to light duty road vehicles (e.g. fuel cell electric vehicles). This document is not applicable to the dispensing of cryogenic hydrogen, or hydrogen to metal hydride applications. Since this document is intended to provide minimum requirements for fuelling stations, manufacturers can take additional safety precautions as determined by a risk management methodology to address potential safety risks of specific designs and applications. While this document is targeted for the fuelling of light duty hydrogen road vehicles, requirements and guidance for fuelling medium and heavy duty road vehicles (e.g. buses, trucks) are also covered. Many of the generic requirements within this document are applicable to fuelling stations for other hydrogen applications, including but not limited to the following:
— fuelling stations for motorcycles, fork-lift trucks, trams, trains, fluvial and marine applications;
— fuelling stations with indoor dispensing;
— residential applications to fuel land vehicles;
— mobile fuelling stations; and
— non-public demonstration fuelling stations.
However, further specific requirements that can be necessary for the safe operation of such fuelling stations are not addressed in this document. This document provides requirements for and guidance on the following elements of a fuelling station (see Figure 1 and Figure 2):
— hydrogen production/delivery system:
— delivery of hydrogen by pipeline, trucked in gaseous and/or liquid hydrogen, or metal hydride storage trailers;
— on-site hydrogen generators using water electrolysis process or hydrogen generators using fuel processing technologies;
— liquid hydrogen storage;
— hydrogen purification systems, as applicable;
— compression:
— gaseous hydrogen compression;
— pumps and vaporizers;
— gaseous hydrogen buffer storage;
— pre-cooling device;
— gaseous hydrogen dispensing systems.
