Standards Development

Scope

This clause of IEC 60335-2-40 is replaced by the following.

This part of IEC 60335 deals with the safety of electric parking air conditionersfor cooling and/or heating driver/s and habitation compartments only when the vehicle is stationary, with electrical input power being not greater than 4kW. Their maximum rated voltage being not more than 300 V for single phase appliances and 600 V for multi-phase appliances and between 12V and 48V battery operated appliances.

The appliances referenced above can consist of one or more factory -made assemblies. If provided in more than one assembly, the separate assemblies are used together, and the requirements are based on the useof matched assemblies.

NOTE 201: Different from the automobile air conditioner as an integral part, the parking air conditioner does not correspond to the model one by one, and the product can be applied to multiple types of vehicles.

NOTE 202: The parking vehicle air conditioner may be of factory -installed and aftermarket products.

NOTE 203 Dual supply appliances, either mains -supplied or battery-operated, are regarded as battery - operated appliances when operated in the battery mode. Examples of the vehicles where the parking air conditioners within the scope of this standard can be installed, are:

– Vehicles used for the carriage of passengers and comprising not more than eight seats in addition to the driver's seat, (M1) -only for aftermarket air conditioner with the compressor unit located outside the vehicle;

– Vehicles used for the carriage of passengers, comprising more than eight seats in addition to the driver's seat, and having a maximum mass not exceeding 5 tonnes.(M2) - only for aftermarket air conditioner with the compressor unit located outside the vehicle;

– Vehicles used for the carriage of passengers, comprising more than eight seats in addition to the driver's seat, and having a maximum mass exceeding 5 tonnes(M3) – maybe for aftermarket;

– Vehicles used for the carriage of goods and having a maximum mass not exceeding 3.5 tonnes(N1) - for both factory installed and aftermarket;

– Vehicles used for the carriage of goods and having a maximum mass exceeding 3.5 tonnes but not exceeding 12 tonnes(N2) - for both factory installed and aftermarket;

– Vehicles used for the carriage of goods and having a maximum mass exceeding 12 tonnes(N3) - for both factory installed and aftermarket;

– Trailers with a maximum mass not exceeding 0.75 tonnes (O1) -eg. Caravans, excluding food stuff trailers covered by ISO 20854;

– Trailers with a maximum mass exceeding 0.75 tonnes, but not exceeding 3.5 tonnes(O2) –eg. Caravans, excluding food stuff trailers covered by ISO 20854;

– Trailers with a maximum mass exceeding 3.5 tonnes, but not exceeding 10 tonnes(O3) -eg. Caravans, excluding food stuff trailers covered by ISO 20854;

– Trailers with a maximum mass exceeding 10 tonnes (O4) – maybe?( Further research if persons could be stayed in such larger trailers(considering labs in the trailer));

– "Motor caravan"(SA) - A special purpose M1 category vehicle constructed to include accommodation space which contains at least the following equipment:(a)Seats and table;(b)Sleeping accommodation which may be converted from the seats;(c)Cooking facilities; and(d)Storage facilities;

– "Ambulance” (SC)-which is a type of motor vehicle of category M intended for the transport of sick or injured people and having special equipment for such purpose;

– Special motor vehicles - which are equipped with special equipment or appliances designed and manufactured for use in engineering (including health and medical) operations, such as a crane truck, fire truck, concrete pump vehicle, repair vehicle, overhead working truck, road sweeping vehicle, sewage suction vehicle, drilling vehicle, instrument vehicle, testing vehicle, monitoring vehicle, power supply vehicle, communication vehicle, TV vehicle, blood collection vehicle, medical vehicle, medical examination car, etc. But they do not include those which have special equipment or apparatus and which have more than nine(or eight) seat, including drive seat;

– any motorised, wheeled or tracked agricultural or forestry vehicle (T), having at least two axles and a maximum design speed of not less than 6 km/h, the main function of which lies in its tractive power and which has been especially designed to pull, push, carry and actuate certain interchangeable equipment designed to perform agricultural or forestry work, or to tow agricultural or forestry trailers or equipment; it may be adapted to carry a load in the context of agricultural or forestry work and/or may be equipped with one or more passenger seats;

– off-road vehicles (G), which are considered to be any type ( M or N or O )of vehicles which are capable of driving on and off paved or gravel surface. It is generally characterized by having large tires with deep, open treads, a flexible suspension, or even caterpillar tracks. This standard does not take into account refrigerants other than group A1, A2L, A2 and A3 as defined by ISO 817. Flammable refrigerants are limited to those of a molar mass of more than or equal to 42 kg/kmol based on WCF (worst case formulation) as specified in ISO 817.

As far as practical, this standard deals with common hazards presented by appliances that are encountered in normal use and assumes that installation, servicing, decommissioning, and disposal are safely handled by competent persons and accidental release of refrigerants is avoided. However, it does not prescribe the criteria to ensure competence of persons during installation, servicing and disposal. Safety requirements during disposal are not specified in this standard.

NOTE 204 Annex HH provides informative requirements on competence of persons. Criteria for competence of personnel for the purpose of certification schemes can be found in ISO 227121.

Unless specifications are covered by this standard, including the annexes, requirements for refrigerating safety are covered by:

– ISO 5149-1:2014, ISO 5149-1:2014/AMD1:2015, and ISO 5149-1:2014/AMD2:2021,

– ISO 5149-2:2014 and ISO 5149-2:2014/AMD1:2020,

– ISO 5149-3:2014 and ISO 5149-3:2014/AMD1:2021.

Supplementary heaters, or a provision for their separate installation, are within the scope of this standard, but only heaters which are designed as a part of the appliance package, the controls being incorporated in the appliance.

NOTE 205 Attention is drawn to the fact that

• for appliances intended to be used on-board ships or aircraft, additional requirements can be necessary;

• in many countries, additional requirements are specified, for example, by the national health authorities responsible for the protection of labour and the national authorities responsible for storage, transportation, building constructions and installations.

NOTE 206This standard does not apply to

• appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas)

Purpose

It was the Decision of SC61D in the 2023-11-12 Plenary meeting to create a new standard for air- conditioners and heat pumps installed in parked vehicles.
