ABSTRACT:
In a method for testing mass-produced articles a test cycle is run during transport of said articles from a first predetermined position to a second predetermined position. During said transport the articles are provided with a connection to an electric mains for supplying the article with operational power, with a control means for controlling the article through a predetermined series of program steps for simulating a cycle of operational use, sensing means for sensing an operational condition of said article and storing means for indiscriminately storing output signals of said sensing means. Upon arrival at said second predetermined position said storing means is connected to a data processing means, whereby the signals stored therein are processed for rendering an indication concerning the performance of the article. For obviating the need for installing specific sensor elements within the article a principle quantity measured is the level and variation of the input current consumed by the article under test (at a constant mains voltage) during the execution of the successive program steps. If the mains voltage is variable in time, the variation is properly corrected for during the measurements.
