Railway applications - Axlebox condition monitoring - Interface and design requirements - Part 2: Performance and design requirements of on-board systems for temperature monitoring
This European Standard defines the minimum performance requirements of on-board monitoring systems for axlebox condition monitoring by means of temperature measurements. This European Standard refers to temperature monitoring of the axlebox. However, the design may be such that the rolling bearing itself is monitored directly. The requirements of this European Standard are intended to apply equally to basic monitoring systems for monitoring the axlebox temperature through to more technically complex systems that may employ a combination of mechatronics. To ensure the compatibility of monitoring systems and the effective monitoring functions, this European Standard defines the requirements in the following areas: - equipment and characteristics; - monitoring performance; - operation and interface. This part of EN 15437 does not include: - systems that do not give an indication to the driver; - how an on-board monitoring system is structured and how it measures the temperature and identifies axlebox position. This is considered part of equipment design and not part of the functional re

Railway applications - Axlebox condition monitoring - Interface and design requirements - Part 1: Track side equipment and rolling stock axlebox
This part of EN 15437 defines the minimum characteristics for the interface between a trackside Hot Axlebox Detector (HABD) and Rolling Stock (RST) that comply with the European Directives for Interoperability to ensure that the minimum functional requirement of the interface is achieved. The minimum requirements of the interface apply to: a) Rolling stock conforming to standard European railway gauge, that is 1 435 mm; b) Rolling stock axles fitted with outboard bearings; NOTE 1 The design of rolling stock axles fitted with inboard bearings should respect the requirements set out in Note 2 of 5.2. c) Rolling stock with a maximum design speed lower than 250 km/h; NOTE 2 Interoperable rolling stock with a maximum design speed higher than or equal to 250 km/h are mandated to have on-board equipment for axlebox condition monitoring. The requirements for on-board equipment are described in !EN 15437-2:2012+A1:2022. NOTE 3 Interoperable rolling stock with a maximum design speed higher than or equal to 250 km/h are outside the scope of this Part of the standard. However, if such rolling st

Durability of wood and wood-based products - Determination of treatability of timber species to be impregnated with wood preservatives - Laboratory method
This document specifies a laboratory method for the determination of the treatability of wood in order to determine the likely reaction of different wood species to impregnation with wood preservatives. It is also applicable to investigate variation between samples of the same species but of different origin.

Hot rolled products of structural steels - Part 4: Technical delivery conditions for thermomechanical rolled weldable fine grain structural steels
This document specifies technical delivery conditions for flat and long products of hot rolled weldable fine grain structural steels in the thermomechanical rolled condition in the grades and qualities given in Tables 1 to 3 (chemical composition) and Tables 4 to 6 (mechanical properties) in thickness ≤ 150 mm. The steels specified in this document are especially intended for use in heavily loaded parts of welded structures such as, bridges, flood gates, storage tanks, water supply tanks, etc., for service at ambient and low temperatures.

Railway applications - Wheelsets and bogies - Part 1: Design method for axles with external journals
This European Standard: — defines the forces and moments to be taken into account with reference to masses, traction and braking conditions; — gives the stress calculation method for axles with outside axle journals; — specifies the maximum permissible stresses to be assumed in calculations for steel grade EA1N, EA1T and EA4T defined in EN 13261; — describes the method for determination of the maximum permissible stresses for other steel grades; — determines the diameters for the various sections of the axle and recommends the preferred shapes and transitions to ensure adequate service performance. This European Standard is applicable for: — axles defined in EN 13261 — powered and non-powered axles and — all track gauges3. The powered axle design method of this European Standard applies to: — solid and hollow powered axles for railway rolling stock; — solid and hollow non-powered axles of motor bogies; — solid and hollow non-powered axles of locomotives. The non-powered axle design method of this standard applies to solid and hollow axles of railway rolling stock used for the transpo
