Nesigurnost uzorkovanja - Nordtest prurucnik za planiranje uzorkovanja vezano za obezbeenje kvaliteta uzorkovanja i procenu nesigurnosti (NT TR 604 - Serbian)

NT TR 604 - Serbian

  • The handbook provides practical guidance on sampling uncertainty estimation in the Nordtest TR handbook format. The handbook is an extract of and based upon the principles, methods and text of the international Eurachem Guide Estimation of measurement uncertainty arising from sampling. The Eurachem guide is more extensive and provides details on theory and additional examples. The basic reference for the text in this handbook is the above-mentioned Eurachem guide.

New method for conformance assessment of radio transmitters (NT TR 589)

NT TR 589

  • In this project a measurement of the effective radiated power (ERP) is compared to a measurement of the total radiated power (TRP). ERP is measured according to ETSI inside an anechoic chamber and TRP is measured inside a reverberation chamber. The measured TRP value is related to the ERP value via an estimated maximum directivity of the test object.

Nordic evaluation of methods for testing fresh self-compacting concrete (NT TR 558)

NT TR 558

  • In this study a modified inter-comparison test was proposed for evaluating the precision of methods for testing fresh SCC whose properties are not identical from laboratory to laboratory or even from batch to batch. The modification includes collecting a number of sets of similar equipment and carrying out a local inter-comparison test in each laboratory by different operators, each operating a number of sets of equipment.

Nordic Round Robin and Investigation on IMO Resolution A 653 (16) (NT TR 529)

NT TR 529

  • This Nordtest Project critically examines the deviations from the IMO resolution A.653 (16) method, which the participating laboratories either uses or has been using, that being deviations from: the equipment, the procedures or the interpretation of data. These deviations are in many cases a result on the imprecise and equivocal description of the method described in the IMO resolution A.653 (16) in FTP Code.

Natural stones: Determination of sensitivity to accidental staining (NT BUILD 514)

NT BUILD 514

  • This Nordtest method describes a laboratory procedure for determining the sensitivity of natural stones when exposed to accidental staining. It contains a standardised procedure for the application of the stains, the cleaning and the assessment of the surface appearance after cleaning. It also covers the possibility to assess the efficiency of a surface treatment. Note that the method does not intend to present any de-staining technique!
