FIELD: test equipment.SUBSTANCE: invention relates to method of carrying out climatic tests of various products, particularly radio products. Method for testing radio products, including placement of tested product in climatic compartment of sealed chamber with exposure to low temperature. If a defect of the product is detected in the chamber, its elements in disassembled form are subjected to additional point low-temperature impact outside the chamber with subsequent detection of faulty element of the product and its replacement. Wherein device for testing radio products is made in form of sealed chamber with process hole containing climatic compartment and cooling system. Chamber with help of mesh partition is divided into upper part of the chamber, containing process hole, and lower part of the chamber. Upper part of the chamber is equipped with corrugated hose with heat insulation. One end of hose is inserted into process hole and rigidly fixed in the chamber casing, and the other end is equipped with a fan with cone nozzle, containing outlet hole of smaller diameter for formation of low-temperature point impact on product elements. Tube passes via hose, one end of which is rigidly fixed with outer side of central part of the hose, and the other one is placed inside lower part of the chamber.EFFECT: technical result is provision of possibility of detecting faulty elements and defects in radio products with high accuracy at impact of temperature factors.2 cl, 1 dwg |
