The black 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 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. The dimension of the test corner can be customized as per the specimen, the test corner is consisted by two side plates, one bottom and one top plate (top plate is selectable), the top plate can be removed or fixed, bottom plate mounted on a ...

The dust and sand test is structured into three groups   in standard IEC60068-2-68 : La:  non-abrasive fine dust. A test which is primarily oriented towards investigation of the seals of the test specimen. The test specimen is exposed to a very fine dust in the form of talc or an equivalent. The effects of temperature cycling resulting in a pressure difference between the inside and outside of the specimen may be reproduced. Lb:  Free setting dust. A test which is oriented towards investigation of the effects when simulating conditions at sheltered locations. The test specimen is exposed to a low-density dust atmosphere created by the intermittent injection of a small quantity of dust which is allowed to fall by gravity onto the specimen. Lc: Blown dust and sand. A test which is oriented towards investigation of the seals and the effect of erosion when simulating outdoor and vehicle conditions. The test specimen is exposed to either a turbulent or a laminar air flow to wh...
