IPETRONIK is one of the few companies in Europe to have been accredited by the Federal Motor Transport Authority as a test laboratory for determining R134a leakage rates. The accreditation was granted on 20.12.2007 and was valid until October 2018, authorizing the company to carry out leakage measurements in accordance with Directive 2006/40/EC including Regulation 706/2007 on automotive air conditioning systems and their components within the scope of KBA type approval. Since 2017, this type approval is no longer required by the KBA for air conditioning systems, as in Europe only new registrations of vehicles with a refrigerant with a global warming potential (GWP) <150 are permitted. IPETRONIK stands for environmental protection, because partially fluorinating greenhouse gases have not yet been completely eliminated, as vehicles with the refrigerant R134a are still on the roads. Here, too, the leakage rates of components must be kept as low as possible and the GWP must be reduced, for example, by using refrigerant mixtures. IPETRONIK has been operating the leakage laboratory since 2017 in order to continuously drive improvements in sealing concepts in the field of air conditioning and to detect faulty components at an early stage before they go into series production at the automotive manufacturer. IPETRONIK thus makes a decisive contribution to ensuring a high level of quality of the air conditioning systems and ease of service to the customer.
