Conditions of equivalence of a suspension-to-air suspension

• 1.This section lays down the technical conditions relating to the equivalence of a suspension to air-suspension for vehicle driving axle(s).

• 2.In order to be recognised as equivalent to air suspension, a suspension shall comply with the following requirements:

• During free transient low-frequency vertical oscillation of the sprung mass above a driving axle or group of axles, the measured frequency and damping with the suspension carrying its maximum load shall fall within the limits defined in points 2.3. to 2.6.

• 2.1.Each axle shall be fitted with hydraulic dampers. On groups of axles, the dampers shall be positioned to minimise the oscillation of the groups of axles.

• 2.2.The mean damping ratio Dm shall be more than 20 % of critical damping for the suspension in its normal condition with hydraulic dampers in place and operating.

• 2.3.The damping ratio Dr of the suspension with all hydraulic dampers removed or incapacitated shall be not more than 50 % of Dm.

• 3.1.Frequency and damping

• 3.1.1.The free oscillation of the sprung mass shall be given by the following equation:

Image omitted; see official source

• Where

‘M’is the sprung mass (kg),

‘Z’is the vertical displacement of the sprung mass (m),

‘C’is the total damping coefficient (N.s/m) and

‘K’is the total vertical stiffness between the road surface and the sprung mass (N/m)

• 3.1.2.The frequency of oscillation (‘F’ in Hz) of the sprung mass shall be given by the following equation:

Image omitted; see official source

• 3.1.3.The damping is critical when C = Co

where:

Image omitted; see official source

The damping ratio as a fraction of critical is C/Co.

• 3.1.4.During free transient oscillation of the sprung mass the vertical motion of the mass will follow a damped sinusoidal path (Figure 2). The frequency can be estimated by measuring the time for as many cycles of oscillation as can be observed. The damping can be estimated by measuring the heights of successive peaks of the oscillation in the same direction.

• 3.1.5.If the peak amplitudes of the first and second cycles of the oscillation are A 1 and A2, then the damping ratio D is given by the following equation:

Image omitted; see official source

‘ln’ being the natural logarithm of the amplitude ratio.

• 3.2.Test procedure

To establish by test the damping ratio Dm, the damping ratio Dr, with hydraulic dampers removed, and the frequency F of the suspension, the loaded vehicle shall be either:

• (a) driven at low speed (5 km/h ± 1 km/h) over an 80 mm step with the profile shown in Figure 1. The transient oscillation to be analysed for frequency and damping occurs after the wheels of the driving axle have left the step;

• (b) pulled down by its chassis so that the driving axle load is 1,5 times its maximum static value. The vehicle held down is suddenly released and the subsequent oscillation analysed;

• (c) pulled up by its chassis so that the sprung mass is lifted by 80 mm above the driving axle. The vehicle held up is suddenly dropped and the subsequent oscillation analysed;

• (d) subjected to other procedures insofar as it has been proved by the manufacturer, to the satisfaction of the technical service, that they are equivalent.

• 3.3.Test equipment of the vehicle and loading conditions

• 3.3.1.The vehicle shall be fitted with a vertical displacement transducer between driving axle and chassis, directly above the driving axle. From the trace, the time interval between the first and second compression peaks shall be measured to obtain the damping.

For twin driving groups of axles, vertical displacement transducers shall be fitted between each driving axle and the chassis directly above it.

• 3.3.2.The tyres shall be inflated to the appropriate pressure recommended by the manufacturer.

• 3.3.3.The test for verifying the equivalence of the suspensions shall be made at the technically permissible maximum mass on the axle or group of axles, and the equivalence assumed to cover all the lower masses.

To that end the lift- or loadable axle(s) shall be lowered to the ground or be loaded automatically if the nearest axle(s) of the group or the front axle(s) of the motor vehicle is/are laden to its/their registration/in- service maximum permissible mass(es).

• Where a lift axle is in elevated position, it shall be ensured that the mass on the steering axle(s) continues to be sufficient to ensure the safe driving of the vehicle in all circumstances. For such purposes, the vehicle manufacturer shall specify, in the case of incomplete vehicles, the minimum mass on the steering axle(s)

• 2.Every axle-lift device fitted to a vehicle, as well as the systems for its operation, shall be designed and installed in such a manner as to protect them against any improper use or tampering.

• 3.Requirements for moving off vehicles on slippery surfaces and to improve their manoeuvrability

• 3.1.By way of derogation from the requirements of point 1 and to help motor vehicles or vehicle combinations to move off on slippery ground and to increase the traction of the tyres on these surfaces as well to improve their manoeuvrability, the axle lift device may actuate the lift- or loadable axle(s) of a motor vehicle or semi-trailer to increase or decrease the mass on the driving axle of the motor vehicle, subject to the following conditions:

• (a) the mass corresponding to the load on each axle of the vehicle may exceed the maximum authorised mass on the axle in force in the Member State by up to 30 % provided it does not exceed the value stated by the manufacturer for this special purpose;

• (b) the mass corresponding to the remaining load on the front axle(s) shall remain above zero (i.e. in case of a rear loadable axle with long rear overhang, the vehicle may not tip up);

• (c) the lift- or loadable axle(s) shall be actuated only by a specific control;

• (d) after the vehicle has moved off and before its speed exceeds 30 km/h, the axle(s) shall automatically be lowered again to the ground or be reloaded.

Explanatory note:

This information document is based on the template laid down in Annex I to Implementing Regulation (EU) 2020/683 and shall be completed with the relevant information under the point numbers listed above as defined in that template.

PART 2

Section A

• 1.For the purposes of this Annex, the following definitions shall apply:

• 1.1.‘burst disc’ means the non-reclosing operating part of a pressure relief device which, when installed in the device, is designed to burst at a predetermined pressure to permit the discharge of compressed hydrogen;

• 1.2.‘check valve’ means a non-return valve that prevents reverse flow in the vehicle fuel line;

• 1.3.‘compressed hydrogen storage system (CHSS)’ means a system designed to store hydrogen fuel for a hydrogen-powered vehicle and composed of a pressurized container, pressure relief devices (PRDs) and shut off device(s) that isolate the stored hydrogen from the remainder of the fuel system and its environment;

• 1.4.‘container’ (for hydrogen storage) means the component within the hydrogen storage system that stores the primary volume of hydrogen fuel;

• 1.5.‘date of removal from service’ means the date (month and year) specified for removal from service;

• 1.6.‘date of manufacture’ (of a compressed hydrogen container) means the date (month and year) of the proof pressure test carried out during manufacture;

• 1.7.‘enclosed or semi-enclosed spaces’ means the special volumes within the vehicle (or the vehicle outline across openings) that are external to the hydrogen system (storage system, fuel cell system and fuel flow management system) and its housings (if any) where hydrogen may accumulate (and thereby pose a hazard), as it may occur in the passenger compartment, luggage compartment and space under the hood;

• 1.8.‘exhaust point of discharge’ means the geometric centre of the area where fuel cell purged gas is discharged from the vehicle;

• 1.9.‘fuel cell system’ means a system containing the fuel cell stack(s), air processing system, fuel flow control system, exhaust system, thermal management system and water management system;

• 1.10.‘fuelling receptacle’ means the equipment to which a fuelling station nozzle attaches to the vehicle and through which fuel is transferred to the vehicle. The fuelling receptacle is used as an alternative to a fuelling port;

• 1.11.‘hydrogen concentration’ means the percentage of the hydrogen moles (or molecules) within the mixture of hydrogen and air (equivalent to the partial volume of hydrogen gas);

• 1.12.‘hydrogen-powered vehicle’ means any motor vehicle that uses hydrogen as a fuel to propel the vehicle, including fuel cell and internal combustion engine vehicles. Hydrogen fuel for passenger vehicles is specified in ISO 14687-2: 2012 and SAE J2719: (September 2011 Revision);

• 1.13.‘luggage compartment’ means the space in the vehicle for luggage and/or goods accommodation, bounded by the roof, hood, floor, side walls, being separated from the passenger compartment by the front bulkhead or the rear bulkhead;

• 1.14.‘liquefied hydrogen storage system (LHSS)’ means liquefied hydrogen storage container(s) PRDs, shut-off device, a boil-off system and the interconnection piping (if any) and fittings between the above components;

• 1.15.‘manufacturer’ means the person or body responsible to the approval authority for all aspects of the type approval process and for ensuring conformity of production. It is not essential that the person or body is directly involved in all stages of the construction of the vehicle, system or component which is the subject of the approval process;

• 1.16.‘maximum allowable working pressure (MAWP)’ means the highest gauge pressure to which a pressure container or storage system is permitted to operate under normal operating conditions;

• 1.17.‘nominal working pressure (NWP)’ means the gauge pressure that characterizes typical operation of a system. For compressed hydrogen gas containers, NWP is the settled pressure of compressed gas in fully fuelled container or storage system at a uniform temperature of 15 °C;

• 1.18.‘maximum fuelling pressure (MFP)’ means the maximum pressure applied to compressed system during fuelling. The maximum fuelling pressure is 125 % of the nominal working pressure (NWP);

• 1.19.‘pressure relief device (PRD)’ means a device that, when activated under specified performance conditions, is used to release hydrogen from a pressurized system and thereby prevent failure of the system;

• 1.20.‘rupture’ or ‘burst’ both mean to come apart suddenly and violently, break open or fly into pieces due to the force of internal pressure;

• 1.21.‘safety relief valve’ means a pressure relief device that opens at a pre-set pressure level and can re-close;

• 1.22.‘shut-off valve’ means a valve between the storage container and the vehicle fuel system that can be automatically activated and defaults to the ‘closed’ position when not connected to a power source;

• 1.23.‘single failure’ means a failure caused by a single event, including any consequential failures resulting from this failure;

• 1.24.‘thermally-activated pressure relief device (TPRD)’ means a non- reclosing PRD that is activated by temperature to open and release hydrogen gas;

• 1.25.‘vehicle fuel system’ means an assembly of components used to store or supply hydrogen fuel to a fuel cell (FC) or internal combustion engine (ICE).

Section B

Technical specifications for the type-approval of liquefied hydrogen storage systems

• 1.Requirements for liquefied hydrogen storage systems (LHSS).

• 1.1.General requirements.

• 1.1.1.This section specifies the requirements for the LHSS. Actual systems will differ in the type, number, configuration and arrangement of the functional constituents. The boundaries of the LHSS are defined by the interfaces, which can isolate the stored liquefied (and/or gaseous) hydrogen from the remainder of the fuel system and the environment. All components located within this boundary are subject to the requirements defined in this Regulation. Figure 1 shows typical LHSS consisting of a hydrogen storage container, three kinds of closure devices and their fittings. The closure devices shall include the following functions, which may be combined:

• (a) Automatic shut-off device;

• (b) Boil-off system; and

• (c) Pressure relief device (PRD). Figure 1 Typical liquefied hydrogen storage system Image omitted; see official source
