AbstractAbstract
[en] ENDEF, an initiative of the European Commission, DG XVII (Energy) was well supported by the European industrial institutions working in assistance with nuclear industrial organisations in the CEEC's (Central and Eastern European Countries) and NIS's (New Independent States). This Forum provides effectively a platform for open discussion between representatives of industrial actors active in the NDE (Non Destructive Examination)/ISI (In Service Inspection) field with the purpose to establish a co-operation pattern between qualified representatives of the EU (European Union) industry to offer a better co-ordinated and well defined assistance to the CEEC's and NIS in the field of NDE/ISI, and to lay the ground for further industrial co-operation. ENDEF developed a strategy to follow for the establishment of co-operation projects. This strategy is now used to understand the extent of past or present assistance projects and to identify the areas where more co-operation is needed. ENDEF encourages the creation in the NIS's and CEEC's of similar forums in order to increase the co-operation and co-ordination. ENDEF is also working in perfect agreement with the European Network ENIQ, piloted by the European plant operators. This identity of views lead to the leadership by the ENDEF co-ordinator of the ENIQ Task 3 involving Applications of the European Methodology for ISI qualification in the CEEC's and NIS's and presently fully integrated in ENDEF.

AbstractAbstract
[en] The joint treatment of concrete is one of the technical problems in top down construction method. Joints created with the top down construction result in serious weakness from the aspects of both structural and water-barrier function. Ultrasonic method was used for the inspection of top down construction joints of a various column in SRC structure in this study. The advantages and limitations of this method for non-destructive inspection in top down construction joints are investigated. As a result, it has been verified that the semi-direct measurement method is more effective than the other methods for detecting the voids of construction joints using ultrasonic method

AbstractAbstract
[en] Using guided wave has a many advantages for save time and cost. It can be a wide range nondestructive testing about wave derivatives like pipe laying or sheet. So, they have been progressing about guided wave study to apply and understand. Guided wave have two big different point with volume guided wave. It has a dispersion. So, an electric wave speed depends on vibration number and thickness of wave derivatives. And, it exists unlimited different electric wave quality mode. This report understand about guided wave of pipe laying and sheet and show about its conception to present experimental example and theorized result about dispersion mode, selection and confirmation to apply nondestructive testing.

AbstractAbstract
[en] To determine detection capabilities of locating of steel bars inside concrete, commercially available Nondestructive Testing(NDT) equipments have been tested. The equipments include two radar systems and one eletromagnetic method system. The inclusions are 13, 16, 19, 25 and 55 mm diameter steel bar, φ30 mm PVC pipe, φ50 mm sheath, wood(2x10 cm), styrofoam(2x10 cm) and water container(15x30 cm) embedded at different cover depths from the surface of concrete specimens. And, the horizontal spacing of steel bars are varied ranging from 5 to 35 cm to determine the horizontal spacing of them. Experimental results on various measurement cases are discussed. From this study, it is proved that radar measurements is good to detection of locating and spacing of steel bars and electromagnetic method effective to detection of locating of them

AbstractAbstract
[en] Evaluation of the quality of concrete in structures, especially strength estimation is said to be one of the most important problem and needed to establish test method especial tv for non-destructive method in situ. The paper describes the nondestructive test to estimate strength of concrete. From experimental study using full scale model wall, strength estimating equations are proposed by ultra-sonic pulse velocity, rebound hardness of Schmidt hammer and combined with two methods. From statistical study of the results of experiments, errors of estimated strength by the proposed equations are suggested. The validity of the equations are verified by investigation for existing reinforced concrete buildings aged 20 - 50 years. And it was found from the statistical study that the strength estimating equations need to be corrected in applying to tons aged concrete, and correction factor to those squat ions were suggested. Furthermore the corrected proposed equations were verified by applying to buildings investigated the other case.

AbstractAbstract
[en] A near-field millimeter-wave (mm-wave) imaging system has been designed and built in the 94-GHz range for on-line inspection of nonmetallic (dielectric) materials. The imaging system consists of a transceiver block coupled to an antenna that scans the material to be imaged; a reflector plate is placed behind the material. A quadrature IF mixer in the transceiver block enables measurement of in-phase and quadrature-phase components of reflected signals with respect to the transmitted signal. All transceiver components, with the exception of the Gunn-diode oscillator and antenna, were fabricated in uniform blocks and integrated and packaged into a compact unit (12.7 x 10.2 x 2.5 cm). The objective of this work is to test the applicability of a near-field compact mm-wave sensor for on-line inspection of sheetlike materials such as paper, fabrics, and plastics. This paper presents initial near-field mm-wave images of paper and fabric samples containing known artifacts
