Frequently Asked Questions
CEN/TC 182/WG 5 is a Working Group within the European Committee for Standardization (CEN). It is named "Risk assessment from the use of flammable refrigerants" and is responsible for: Risk assessment with the aim to minimize the risk from the use of flammable refrigerants in refrigerating systems including portable systems. This committee has published 1 standards.
CEN/TC 182/WG 5 develops CEN standards. The scope of work includes: Risk assessment with the aim to minimize the risk from the use of flammable refrigerants in refrigerating systems including portable systems. Currently, there are 1 published standards from this working group.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
The document gives a scheme for carrying out a risk assessment for flammable refrigerants in case of house-hold refrigerators and freezers with refrigerants of group A3 according to EN 378 1, taking into consideration a sealed system and a refrigerant charge of not more than 150 g. Sealed systems are refrigerating systems in which all refrigerant containing parts are made tight by welding, brazing or similar permanent connection.
NOTE For risk assessment the method with flow diagrams is selected, because these are helpful for checking the possible ignition of the whole appliances and to estimate the probability of ignition. It takes EN ISO 12100, EN 1050, EN 1127, EN 60335 2 24/A53, E DIN 7003 into consideration.
At least the probability of deflagration is the product of multiplication of the probability of defects of different components and the probability for the presence of explosive atmosphere and the probability for the ignition sources.
