Ahmed Mahmoud Ahmed Ghawanmeh. Development of uniform data collection and processing systems of accelerated tests for complex items. - Manuscript. Thesis for Academic Degree of Candidate of Technical Science on specialty 05.01.02 - Standardization and Certification. - Kiev National University of Technologies and Design, Kiev, 2001. The thesis solves scientific and technical problem concerning development of uniform data collection and processing systems of complex (items) articles accelerated tests for assessment of items deflected mode on the base of the energy method of control while production, operation and maintenance of complex articles (items) According to complex experimental investigations it is proved that external energy direct potential measurement while items surface control zone ionization provides simultaneous authentic and accurate reciept, analysis and processing of complex (items)articles accelerated tests data. It is determined that improvement of estimate reliability of thin surfac e layers (up to 10 mkm) technical state, in which dangerous metal items defects can occurs and develop, can be achieved by measurement of their structure and phase inhomogeneities parameters. It is shown that information about structure and phase inhomogeneities for diagnostic equipment system operation can be obtained by examination of external energy potential distribution above inhomogeneities localization by means of discriminating measuring device making the basis of reference documents development for conduct of accelerated tests. Acquired dependencies allowed to develop a standard process flow diagrams for detection of structure and phase inhomogeneities and lattice microdeformation gradient of complex items surface layers. Used system allows to conduct analysis of metals and alloys surfaces quality on different physical and chemical characteristics with accuracy sufficient for production. Developed reference data base (methodology, algorithm, control assembly chart) is approved on the number of e ngineering plants of Ukraine and firms of Jordan during development of uniform data collection and processing systems of complex (items) articles accelerated tests. Key words: uniform systems, accelerated tests, complex items, data base, reliability, production quality, nondestructive check, check object, structure and phase inhomogeneities, diagnostic equipment system.
