CEN/TC 413 - Project Committee - Testing methodologies and requirements for insulated means of transportation

This document specifies requirements for the use of flammable refrigerants class A2L, A2 and A3 as defined in ISO 817 with regard to:
-   design and construction of the refrigerating system (as far as not specified in EN 378-2);
-   operation;
-   in all anticipated operational modes and locations;
-   including continuous idling during standstill;
-   service, maintenance and decommissioning;
-   for the investigation and mitigation of risk for thermally insulated means of transport, including: trucks, trailers, tanks, vans (light commercial vehicles), wagons, containers for land transport, small containers, packaging.
This document describes an Operational Mode Risk Assessment (OMRA), which uses methods such as Hazard and Operability Analysis (HAZOP), Failure Mode and Effects and Criticality Analysis (FMECA), or Fault Tree Analysis (FTA) or a combination of these methods.
The document specifies requirements:
-   for the validation of possible safety concepts and protective devices within the OMRA process, including charge release tests, simulation, and function tests of the associated protective equipment;
-   for tests related to the application;
-   using methodologies to achieve tolerable risk values.
Mobile air conditioning systems in cars are covered in ISO 13043 and refrigerated containers conforming to ISO 20854 are excluded.
This document could be used for class "B" refrigerants providing the OMRA is adjusted to account for their specific properties.

This document is applicable to eutectic cooling devices which are intended to be used with insulated transport equipment.
The following applications are covered:
-   Eutectic cooling devices with or without compressor/condenser unit intended to be installed into insulated means of transport (e.g. lorries, trailers, swap bodies, other transport equipment and wagons). Charging of the eutectic elements from the liquid to the solid phase can be performed either by a compressor/condenser unit mounted onto the vehicle or by a stationary direct or indirect system. The eutectic cooling devices are equipped, if relevant, with necessary components for the charging, transmission, cooling and/or with temperature control devices. The eutectic elements can be fitted with or without fans;
-   Eutectic cooling devices with independent eutectic elements are not covered by this document.
This document specifies the testing methodologies.
This document is only applicable for mono-temperature eutectic cooling devices. This document does not provide any safety requirements.

This document applies to all thermally insulated means of transport, including: trucks, trailers, tanks, vans, wagons, containers for land transport, small containers, packaging. It is related to every type of insulation. If certain temperatures are due to be maintained independently of external conditions, the above means of transport could be additionally provided with a cooling and/or heating device.
This document specifies the terminology, the requirements for thermal insulation, air tightness, test provisions, dimensioning of containers with and without cooling and/or heating device.
This document also specifies the test provisions for new and in service equipment(s).
This document specifies the terminology, the requirements for thermal insulation, air tightness, test provisions for K-value. This document does not specify further land transport requirements with regard to dimensions, weights, etc. This document does not cover safety requirements. This document does not specify special requirements for sea containers covered by ISO 1496-2.

This European Standard applies to mechanical cooling devices with air circulation heat exchangers with or without heating device. The mechanical cooling devices are intended to be used with insulated transport equipment. They include a drive or a means of force transmission and are provided with all the components necessary for the controlled thermal transport system. The mechanical cooling devices can be powered with independent engine and/or vehicle engine and/or any other source of energy. This standard specifies the testing methodologies.

The document applies to thermally insulated means of transport used for temperature sensitive goods equipped with a cooling and/or heating device.
This document specifies the terminology, the requirements for thermal insulation, air tightness, dimensioning of equipment with cooling and/or heating device for long distance and distribution transport.
This document does not specify further land transport requirements with regard to dimensions, weights, etc. Further this standard does not cover safety requirements or special requirements for thermal containers covered by ISO 1496-2.
