Évaluation de l'incertitude de mesure d'un processus stationnaire autocorrélé
Le présent document décrit une méthode pour évaluer l’incertitude-type de la moyenne d’un processus, qui provient d’une variation observable de mesurages successifs éventuellement autocorrélés. Dans le présent document, les mesurages successifs sont limités aux processus stationnaires. Le présent document comprend également des tests de validité des hypothèses. L’incertitude résultante est liée à…

Natural gas — Determination of water by the Karl Fischer method — Part 1: General requirements
This document specifies general requirements for the determination of water in natural gas using the Karl Fischer method (see Reference [1]).
ISO 10101-2 and ISO 10101-3 specify two individual methods of determination, a titration procedure and a coulometric procedure, respectively.
Natural gas — Determination of water by the Karl Fischer method — Part 2: Volumetric procedure
This document specifies a volumetric procedure for the determination of water content in natural gas. Volumes are expressed in cubic metres at a temperature of 273,15 K (0 °C) and a pressure of 101,325 kPa (1 atm). It applies to water concentrations between 5 mg/m3 and 5 000 mg/m3.
Railway infrastructure — Rail fastening systems — Part 4: Test methods for resistance to repeated lo...
This document specifies a laboratory test procedure for applying repeated load cycles which generate displacement cycles representative of the displacements caused by traffic on railway track. It is used for assessing the long-term performance of rail fastening systems.
This document is applicable to surface mounted rail on sleepers, bearers and slab track and embedded rail.
This test procedure…
