International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1972
Abstract An index test for strength classification of rock materials is described. The test uses portable equipment. Specimens require no machining and can take the form of either rock core or irregular lumps. A single ‘point-load strength index’ can be obtained whatever the shape of specimen, provided that this shape is maintained within prescribed ...

Points of Load: Performance test in high-B environment
2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2015The performance in magnetic field (B-field) of a DC-DC converter ad hoc designed for LHC operation has been evaluated. The tests have been carried out at the Laboratorio Acceleratori e Superconduttivita Applicata (LASA), in Milan (Italy), in the first months of 2014 and the experimental results are here presented and discussed.

Comparison of Averaging Procedures for Point Load Testing of Rock
Geotechnical Testing Journal, 2008Abstract This paper presents the experimental results of a laboratory point load testing program carried out to analyze the effect of two different point load mean value calculation procedures on the prediction accuracy of uniaxial compressive strength of rocks.

Analog/digital testing of loaded boards without dedicated test points
Proceedings International Test Conference 1996. Test and Design Validity, 2002This paper describes a new way to consider loaded board test fixturing, meeting the challenges of testing high density analog/digital loaded boards, such as mobile phones, camescopes, PCMCIA or fax boards. This method allows board area space savings of 7 to 15%.

Point of Load for LHC experiments: Testing the behaviour in hostile environment
2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2014Devices used in future experiments at LHC will be called to work in a very hostile environment. Power supply is a key aspect in this scenario, and new converters will be re-designed in order to meet the future requirements. Moreover, also Point of Load (PoL) converters, as circuits able to adapt the voltage level for each board, device and situation ...

The point-load test in geotechnical practice
Engineering Geology, 1975Abstract The point-load test is evaluated for practical applications in engineering geology. The three variations of the test, i.e., diametral, axial and irregular lump are assessed and it is found that the diametral point-load test is most convenient and reliable in use.

The Effect of Specimen's Height on the Point Load Test
Advanced Materials Research, 2013In order to use different size of the rock in the site point load tests, select the same site at the scene of specimen do load test research. Through the statistical analysis of 9 groups of the point load strength index data, demonstrates the influence of the test specimen size and shape sample size and shape to rock point load test results, and draws ...
