Temperature Rise Black Test corner
1. Introduction
Test corner is designed according to IEC60335-1 chapter 11 “heating”. It is applied to provide a standard required conditions for temperature rising test of electric appliance. The dimension and temperature measurement arrangement of test corner can be customized according to the sample under test.
The Black Test Corner is used for the measurement of the temperature radiated by different equipment during the tests from heating and abnormal operation. One is designed and made with the intention of determining the fulfillment of different standards as far as the registry from temperatures during the operation of the apparatus under test.
The Black Test Corner is conformed by a trihedral or tetrahedron one of black painting plywood, with a matrix of holes each 100 mm that allow to adapt thermocouples of measurement easily, specially designed for such case.
Thermocouples of measurement is of curved type K ( Ø0.3mm), mounted on terminal block, and in its end of measurement they have a copper disc of Ø15 mm and 1 mm of thickness. The amount of thermocouples is according to the necessity of the client.
