AbstractAbstract
[en] Visual acuity tests for radiographic inspectors should be correlated with the type of tasks encountered in real world radiography. The testing procedures should be capable of assessing differences in day to day performance of a given inspector as well as the performance of one inspector relative to other inspectors. Single line targets with specific parametric values for contrast, width, and blur are recommended to provide a means for testing a radiographic inspector for visual acuity. These targets may be used for periodic tests by the employing organization or for more frequent self testing by the inspector. Statistics from the National Health Survey, procedures recommended by the NAS-NRC Committee on Vision and real world radiographs have been utilized in arriving at recommended test configurations

AbstractAbstract
[en] In the framework of mechanical tests and to answer the different requests for tests, the T.C.R (Transport Conditionnement et Retraitement) laboratory got test facilities. These installations allow to carry out tests of resistance to shocks, mainly at the safety level of components of nuclear power plants, mockups of transport casks for fuel elements and transport containers for radioactive materials. They include a tower and a catapult. This paper give a decription of the facilities and explain their operation way

Dans le cadre des essais mecaniques et pour repondre aux differentes demandes d'essais, le laboratoire T.C.R. (Transport Conditionnement et Retraitement) du service SYSTEME s'est dote d'installations d'essais. Ces installations lui permettent d'effectuer des essais de tenue aux chocs, principalement au niveau de la Surete sur des: composants de centrale nucleaire, maquettes de chateaux de transports d'elements combustibles, et emballages de transports de substances radioactives. Elles comprennent: une tour d'essais de chutes et une catapulte. Apres avoir decrit les installations, on expose leur principe de fonctionnementOriginal Title

AbstractAbstract
[en] A formalism for analyzing the reliability R of an interval for system probability of failure and its confidence C from the component R-C intervals is outlined. In the general formalism one must obtain the network representation of the system with path failure probabilities indicated, derive by an algorithm a representation of the system by disjoint paths, declare an R-reliable interval for each component probability of failure, and derive the confidence in that interval. This formalism is developed with reference to aircraft engine component retirement-for-cause. The network diagram consists of paths for various rotor components. R-C intervals for the path state probabilities and for the system probability failures are calculated. The final solution involves sums and products of a number of integrals which can be quickly evaluated by an integration logorithm

AbstractAbstract
[en] The use of industrial radiology techniques id very important for military explosive fabrication. The cylindrical-ogive bodies made in forged metal have their interior fulfilled with high melted explosive and they must explode when they reach the target. The granades, as these bodies are called, are thrown by cannons and their interior are submitted to high pressures and accelerations which can cause a premature detonation, in most case, in interior of tube, in case of they have defects in explosive mass. The origins of defects, its localization and classification presenting the techniques used and disposable in Brazil are discussed. (M.C.K.)

O emprego de tecnicas de radiologia industrial e extremamente importante no processo de fabricacao de explosivos militares. Corpos cilindro-ogivais feitos em metal forjado tem o seu interior preenchido por um alto explosivo fundido e so devem funcionar (explodir) quando atingirem o alvo. As granadas, como sao chamados esses corpos, sao lancadas de canhoes, sendo submetidas no interior deles a altas pressoes e aceleracoes que podem provocar uma detonacao prematura, na maioria dos casos ainda no interior do tubo, caso existem defeitos na massa de explosivo. Serao discutidas as origens dos defeitos, sua localizacao e classificacao, apresentando de forma suscinta, as tecnicas utilizadas e as disponiveis no Brasil. (Autor)Original Title

AbstractAbstract
[en] During the last five years several approaches were developed as non-destructive methods for strain/stress-measurements not only on the surface but in the interior, too. The state of the art is described in this contribution covering ultrasonic as well as micromagnetic methods. Examples are given from research results and applications in practice. The most important literature differentiated referring to physics, review contributions and applications is listed in an appendix. (orig./HP)
