   • Testing for compliance with the Pressure Equipment Directive (PED).

4. Acoustic and noise tests:

   • Acoustic tests complement comprehensive tests of refrigeration equipment and heat pumps (including tests for obtaining the European quality mark KEYMARK).
   • Measurements include corrected sound pressure level characteristics A and determination of corrected A-weighted sound power level under specified measuring conditions defined in standards PN-EN 12102-1:2018-03, PN-EN 12102-2:2019-06, PN-EN ISO 3744:2011, and PN-EN ISO 3746:2011.

5. Safety testing of electrical equipment for household and similar use – heat pumps, air conditioners, and dehumidifiers:

   • Tests ensure safe operation under controlled and abnormal conditions, including overload of compressor and fan motor circuits.
   • Mechanical strength, resistance to high temperatures, application of component parts, and correctness of grounding connections are evaluated.
   • Tests are conducted according to PN-EN 60335-2-40 standard.

6. KEYMARK for heat pumps – HP KEYMARK:

   • The laboratory conducts necessary tests, verifications, and factory inspections for awarding and controlling products with the KEYMARK.
   • KEYMARK is a European certification mark confirming compliance with European standards, providing added value beyond CE marking by ensuring adherence to uniform European quality standards.

7. Other tests:

   • The laboratory also performs unconventional tests, such as those in thermal-climatic chambers, or designs and executes new test setups tailored to specific research needs in consultation with clients.
