METHOD AND DEVICE FOR COMBINED TESTING Russian patent published in 1994 - IPC

FIELD: testing practice. SUBSTANCE: test object is subjected in succession to combination of external factors applied at time intervals of a certain duration , said duration exerting no substantial influence on parameters and characteristics of test object. Device for realizing said test method comprises climatic chamber 2 reproducing various temperature-humidity conditions, and adapter 3 for fastening test object 21. Side surfaces of said adapter are connected to lower wall of climatic chamber via rubber diaphragm 11 while its lower surface may be attached alternately to platforms of vibrator and impact stand which reproduce various kinds of mechanical loading of test object. EFFECT: higher efficiency of tests achieved by bringing testing conditions closer to real operation, discovering defects in case of critical combinations of factors, realization of factor experiment plans. 4 cl, 7 dwg
