Indoor air quality: Measurement of co2 (NT VVS 114)

NT VVS 114

  • This method determines the overall function of the ventilation system by measuring the carbon dioxide, CO2 generated by the occupants. The primary intention is to measure the room air concentration, CR with one gas analyser. However by using two or more gas analysers the effectiveness or local ventilation index can also be obtained.

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

NT TR 610

  • A relatively high utilisation of district heating and limited resources of drinking water makes metering of water and heat of great importance in both the Nordic and the Baltic countries. This has further resulted in a heavy focus on testing and calibration of the meters as well as on the uncertainty of the meter installation.

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.

Improving heat fluxmeter calibration for fire testing laboratories (HFCAL) (NT TR 527)

NT TR 527

  • Tests of resistance to fire, representing fully developed fires, use more and more often heat flux gauges. In reaction to fire testing the initial stages of the fire are considered, ranging from smouldering cigarettes to small flames and "Single Burning Items". To characterise the thermal load to the test specimen, all national and international test methods need a direct measurement of the heat flux incident on the specimen.
