5 Requirements
5.1 Electrical safety Dental compressors and other parts of the central compressed air source equipment are designed as stationary equipment to be installed in a location separate from dental treatment rooms. To prevent electrical conduction between central compressed air source equipment and the main line for dental air in case of fault condition, hoses or tubes (flexible tubes), which connect the dental compressor with the central compressed air source equipment connection point or, if applicable the quick release coupling device, shall be made from an electrical insulating material. For central compressed air source equipment, the safety requirements of IEC 60335-1 apply. Testing shall be carried out in accordance with IEC 60335-1.
5.2 Electromagnetic compatibility For electromagnetic compatibility (EMC), the following requirements shall apply. Immunity requirements of IEC 61000-6-2 shall apply. Testing shall be carried out in accordance with IEC 61000-6-2. Emission requirements of IEC 61000-6-3 shall apply. Testing shall be carried out in accordance with IEC 61000-6-3.
5.3 Quality of dental air The dental air produced by the central compressed air source equipment shall conform to purity class [2:4:2] according ISO 8573-1.
5.4 Performance
5.4.1? Air? delivery? flow? rate? of? central? compressed? air? source? equipment The manufacturer of central compressed air source equipment shall specify the maximum air delivery flow rate that the equipment is intended to deliver continuously at 0,5 MPa and at the air quality requirement specified under 5.3. Measurements shall be carried out in accordance with 7.2.1 and 7.2.2.
5.4.2 Condensate drain The system shall be equipped with a mechanism to drain off condensate water from all points where condensation may occur, for example a condensate drain at the lowest point of the air receiver, filter and/or dryer. Conformity shall be checked in accordance with 7.1.2.
5.4.3? Bacterial? filter If the central compressed air source equipment includes a bacterial filter it shall be rated to restrict the passage of contaminants larger than 0,22 μm with a retention of 99,99 %. The manufacturer shall specify the method and interval for the filter element replacement. Conformity shall be checked in accordance with 7.1.3
5.4.4 Sound level of central compressed air source equipment The sound pressure level of central compressed air source equipment shall be measured and reported. Testing shall be carried out according to 7.2.4.
5.5 Test report A test report shall be prepared to report the results of all applicable testing and inspection requirements specified in this document. Annex C gives a suggested template for the test report.
6 Sampling One representative sample of the central compressed air source equipment shall be tested.BS EN ISO 22052 pdf download.
