Geležinkelio taikmenys. Ašidėžės. 2 dalis. Pritaikymo naudoti procedūros

This document specifies the principles and methods for deployment of the system of axlebox rolling bearing(s), housing, seal(s) and grease, required for reliable operation of trains on European networks. It covers the conformity assessment with respect to design requirements on the rolling bearing(s) according EN 12080 and grease according EN12081 as well as the performance of (rig) tests according to EN 12082 1 . This document is historically developed for outboard applications with rotating inner rings, but can be used for vehicles with inboard bearing arrangements with rotation inner rings. The present document describes the complete deployment procedure for new axleboxes. For certain cases and based on a documented risk assessment, a reduced deployment procedure is described. This document only applies to axleboxes equipped with rolling bearings and greases according to EN 12080 and EN 12081. It is not within the scope of EN 12082 2 to define the validation procedure of box housings, sleeves or coves from a structural point of view. The relevance of these parts in the scope of this document is limited to the interaction with the axle box rolling bearing with respect to the required service.

Tekstilė. Spalvos atsparumo bandymai. X11 dalis. Spalvos atsparumas lyginimui (ISO/DIS 105-X11:2024)

Tests are given for hot pressing when the textile is dry, when it is wet, and when it is damp. The end-use of the textile usually determines which test should be made. A dry specimen (dry pressing) or a dry specimen covered with a wet cotton adjacent fabric (damp pressing) or a wet specimen covered with a wet cotton adjacent fabric (wet pressing) are pressed with a heating device at a specified temperature and pressure for a specified time.

Aplinkos kietosios terpės. Angliavandenilių nuo C10 iki C40 kiekio nustatymas dujų chromatografija (ISO/DIS 16703:2024)

ISO 16703:2004 specifies a method for the quantitative determination of the mineral oil (hydrocarbon) content in field-moist soil samples by gas chromatography. The method is applicable to mineral oil contents (mass fraction) between 100 mg/kg and 10 000 mg/kg soil, expressed as dry matter, and can be adapted to lower detection limits. ISO 16703:2004 is applicable to the determination of all hydrocarbons with a boiling range of 175 °C to 525 °C, n-alkanes from C10H22 to C40H82, isoalkanes, cycloalkanes, alkylbenzenes, alkylnaphthalenes and polycyclic aromatic compounds, provided that they are not absorbed on the specified column during the clean-up procedure. ISO 16703:2004 is not applicable to the quantitative determination of hydrocarbons < C10 originating from gasolines. On the basis of the peak pattern of the gas chromatogram obtained, and of the boiling points of the individual n-alkanes listed in Annex B, the approximate boiling range of the mineral oil and some qualitative information on the composition of the contamination can be achieved.
