Comparison testing

Comparison of measurements in the black test corner started during the 3rd interim of the project (in 2004). From Estonia, Electrical Safety Controlling Centre was responsible for carrying out the tests (both starry and circular course).

The testing of sample A (1st round, starry course) started on May 24, 2004 and the testing details were the following:
Product: Digital Convection Oven
Test procedure: EVS-EN60335-1; EVS-EN60335-2-9 p. 11
Content of the test: Determining the temperature's rise in black test corner
Results: a report no 9-5/40 was sent to University of Ljubljana on June 3, 2004.

The 2nd round (circular course) of inter-comparison testing was also carried out by Electrical Safety Controlling Centre Ltd. A test report no 9-5/3 was sent to University of Ljubljana.

The results of all the tests (carried out both in Estonia and other project members) were introduced at INCOLAB Conferences both in Sofia in 2004 and in Bled in 2006.

Based on results of the inter-comparison testing in the black test corner it has become evident that the Electrical Safety Controlling Centre could not perform larger number of testing in the scope of market surveillance without proper equipment. One of such items was a black test corner, which needed the upgrade. Because it was possible to realize it within the project, we obtained official endorsement from the European Commission for such action. The upgrade was performed in the last period of the project with the help of Slovenian partner University of Ljubljana, Faculty of Electrical engineering, Laboratory of Metrology and Quality, who made an extensive research on black test corners, which enabled a proper upgrade.

With successful upgrade of the black test corner some objectives of the strategy plan for full implementation of LVD in the period 2007-2010 were already partially realized that is development of testing equipment based on today's needs of producers, importers and Market Surveillance authorities in Estonia as well as improvement of testing services for Market Surveillance could be realized.
