following a serious accident in the North Sea involving the failure of a crane slew ring well within its predicted life

in order to investigate whether a specific International Standard is really required and if it compensates the limitations of the Vickers hardness test currently used

Piezoelectric transducers can have widely differing shapes and may be employed in a range of vibrational modes

The outcome was that CEN decided to publish a new edition of the standard (EN ISO 14971:2012)

Note: Standard conditions of testing are defined in Part 1 of BS EN 60512

Hydraulic fluid power. Monitoring the level of particulate contamination of the fluid - Use of the filter blockage technique Ingestion-build-100998 following a serious accident in1 Scope This part of ISO 21018 specifies a method for the semi quantitative determination of the particulate contamination level using the filter blockage technique (also known as the mesh obscuration method or the pore blockage technique) either on line or off line in containers. It also defines procedures for calibrating the instruments and verifying their correct operation both in the laboratory and in service. In general, the techniques described
