Intercomparison and method for uncertainty calculation of water and heat flow (NT TR 610)

NT TR 610

NT TR 603

• Uncertainties of measurement and prediction of the sound insulation in a building is an important issue to the building industry, because they put increased expenses on all actors of the building process who have to keep safety margins to prescribed requirements. This report deals with estimates of both types of uncertainty and some recommendations on suitable safety margins are given.

Linear calibration of axial load fatigue testing machines (NT TR 579)

NT TR 579

Inter-laboratory comparison of fatigue test with evaluation of the participating laboratories calculations of measurement uncertainty (NT TR 533)

NT TR 533

• In this paper a fatigue testing inter-laboratory comparison is presented. Six Nordic laboratories performed fatigue tests on steel specimens. The specimens were tested with different stress levels (460 MPa, 430 MPa and 400 MPa) and with the load ratio R=Smin/Smax =0.1. On each level four specimens were tested. The participating laboratories reported the results together with measurement uncertainty.

Traceable calibration and uncertainty of measurements in scanning electron microscopy NT TR 252

NT TR 252

• The objective of this study was to develop guidelines for measuring quantitative chemical compositions and dimensions in scanning electron microscopy (SEM) to a predetermined level of uncertainty with the help of the new publication ISO/TAG4/WG 3 (June 1992): Guide to the Expression of Uncertainty in Measurement.

  A literature survey was made in order to see what relevant standards or recognised procedures are available for measurements in SEM.

  This report containes worked examples of uncertainty analysis and application of the ISO/TAG4/WG 3 guide for measurements in SEM. The results of experiments and the literature survey are summarised and the suitability of the ISO/TAG4/WG 3 guide is discussed.
