EMC Test for Compliance with EU EMC Directive 2004/108/EU Partial Test 12-12-2012 Standards Description EN 55022:2011 Information technology equipment - Radio disturbance characteristics - Limits and methods of measurement EN 55024:2010 Information technology equipment - characteristics Limits and methods of measurement Equipment under test (EUT) userver Ver 1.1 userver Evaloard Ver 1.0. Client: Nabto ApS Åbogade 15, 8200, Aarhus N Investigation carried out by: MaJust ApS Åbogade 15, 8200, Aarhus N Test engineer: Jakob Justesen (jju@majust.dk) Test site Jens-EMC ApS Randersvej 6 DK-8600 Silkeborg Denmark Test result: The EUT has undergone all applicable tests without remarks. The EUT is believed to comply with the 2004/108/EU EMC directive. Note: some tests where skipped due to dependency on target system. Page 1 of 13 pages
