Thermal road vehicles - Temperature-controlled systems using flammable refrigerants for transport of goods - Requirements and risk analysis process; German version FprEN 17893:2024
Abstract
This document is only applicable to refrigerating systems used and operated in road transport of temperature sensitive goods. This document specifies requirements for flammable refrigerants class A2L, A2 and A3 as defined in ISO 817 with regard to • design (as far as not specified in EN 378-2); • operation; • in all anticipated operational modes and locations; • including land-based continuous idling during standstill; • service and maintenance; • risk reduction, investigation and mitigation; for • manufacturers of road transport refrigerating systems; • installers; • owners of Light Commercial Vehicles (LCV), trucks or trailers; • operators. This document specifies • an Operational Mode Risk Assessment (OMRA), which uses methods such as HAZOP (Hazard and Operability Analysis), FMEA (Failure Mode and Effects Analysis), or FTA (Fault Tree Analysis) or a combination of these methods; • requirements for the validation and consideration of possible safety concepts and protective devices within the OMRA process, including charge release tests, simulation, and function tests of the associated protective equipment; • test requirements for shock impact and vibration. A validation procedure is given to demonstrate that risks from hazardous events are investigated and their severity and frequency are meaningfully reduced, with the aim of achieving tolerable risk values.
