Qualification of Robotic Laboratory Equipment

Qualification of a Robotic Pipeline Orbital Welding

This work presents the procedure qualification for pipeline orbital welding using a robotic system. The system has four degrees of freedom, which allow the controlling of the stick out, the travel speed, the torch angle and the positioning. The arc voltage and welding current are also controlled during the welding, although the system uses a conventional power source. With the system it is poss...

New Techniques for Vibration Qualification of Vibrating Equipment on Aircraft

All aircraft vibrate and all components are designed, tested and certified to survive these vibration levels over their entire service life. Design standards such as MIL‐STD‐810F (1) and RTCA DO‐160E (2) are often used to obtain the vibration sign‐ off test; but what is the safety margin on these tests? How many hours do they represent on real aircraft? Can the equipment life b...

Qualification of Microprocessor-Based Equipment for Nuclear Power Plant Environments

In the past several years, studies have been performed by Oak Ridge National Laboratory, Sandia National Laboratory, and Brookhaven National Laboratory in a confirmatory research program initiated by the U.S. NRC with the objective of identifying methodologies for enhancing current qualification guidelines for the application of microprocessor-based I&C in safety-related systems in nuclear powe...

Diagnostic equipment outside the laboratory.

A questionnaire was circulated to clinical biochemistry laboratories in the North West Thames region of the United Kingdom requesting information on extralaboratory equipment. Data on the types and numbers of instruments in use, their relationship with the laboratory, and quality assurance procedures were obtained. Laboratories were prepared to maintain equipment over which they had no responsi...
