Rail defects Handbook ASA 3An other interesting publication of the Asset Standards Authority (ASA), an independent unit established within Transport for NSW of Australia.

This manual provides requirements, processes and guidelines for the testing of rail for internal defects and for the acceptance testing of rail welds and weld repairs. The manual is part of RailCorp’s engineering standards and procedures publications. More specifically, it is part of the Civil Engineering suite that comprises standards, installation and maintenance manuals and specifications. Manuals contain requirements, process and guidelines for the management of track assets and for carrying out examination, construction, installation and maintenance activities.telecharger le doc

A new paper in « Polymer Testing« .

This study investigates the use of both amplitude and time-of-flight based pulsed ultrasonic polar scan P-UPS as a sophisticated non-destructive damage sensor for fiber reinforced composites. Focus is put on stiffness related damage phenomena, which are in general difficult to monitor nondestructively, and their associated signature in the P-UPS image. This paper brings out the study, read more via Non Destructive damage assesment in fiber reinforced composites with the pulsed ultrasonic polar scan.
