(Main)Wood poles for overhead lines - Determination of characteristic values
Wood poles for overhead lines - Determination of characteristic values
This European Standard specifies the methods for determining characteristic values for bending strength and modulus of elasticity, of any population of wood poles. It is not intended for routine quality control.
This standard covers only single poles under cantilever or compression loading. For example, this standard does not cover poles used as beams.
The provision of poles for use in any overhead line or cable infrastructure shall take into account a range of factors not covered by this standard which will necessitate the specification by the end user of complementary and synonymous attributes to those defined in this standard. This refers to requirements for a number of factors including safety, overhead plant, handling, fittings, installation machinery and working practices including climbing.
Holzmaste für Freileitungen - Bestimmung von charakteristischen Werten
Diese Europäische Norm legt Verfahren zur Bestimmung von charakteristischen Eigenschaften für die Biegefestigkeit und den Elastizitätsmodul einer beliebigen Grundgesamtheit von Holzmasten fest. Sie ist nicht für regelmäßige Gütekon-trolle vorgesehen.
Diese Norm gilt nur für einstielige Maste als Kragarm und/oder unter Druckbeanspruchung. Diese Norm berücksichtigt zum Beispiel nicht die Verwendung von Masten als Biegeträger.
Der Einsatz von Masten in Freileitungen, erfordert die Berücksichtigung einer Reihe von Faktoren, die in dieser Norm nicht erfaßt sind; der Betreiber kann seine speziellen Anforderungen mit ergänzenden Anforderungen zu den in der vorliegenden Norm definierten vervollständigen. Das betrifft Anforderungen im Hinblick auf die Eignung einer Anzahl von Faktoren, einschließlich Sicherheit, Freileitungsanlage, Handhabung, Zubehör, Hilfsmittel für die Errichtung und Arbeitsvorgängen einschließlich Mastbesteigung.
Poteaux en bois pour lignes aériennes - Détermination des valeurs caractéristiques
La présente norme spécifie les méthodes visant a déterminer les valeurs caractéristiques de résistance a la flexion et du module d'élasticité, propres a une population quelconque de poteaux en bois. Elle n'est pas destinée au contrôle de qualité de routine.
La présente norme s'applique uniquement aux poteaux simples soumis a une charge en porte-a-faux et/ou a une charge en compression. La présente norme ne concerne pas les poteaux utilisés comme poutres, par exemple.
Lors de l'utilisation de poteaux en bois pour un usage au sein de toute infrastructure aérienne de lignes ou de câbles, il est nécessaire de prendre en compte une série de facteurs sortant du domaine d'application de la présente norme, et nécessitant de la part de l'acheteur final, la spécification de prescriptions supplémentaires et synonymes de celles qui sont définies dans la présente norme. Cette nécessité a trait aux prescriptions de conformité a l'égard d'un certain nombre de facteurs relatifs a la sécurité, aux installations aériennes, a la manutention, aux équipements, aux machines d'installation et aux pratiques d'usage, y compris l'escalade.

EN 12511:2001 (E)4IntroductionThis standard is one of five standards covering requirements for visual or machine grading, test methods,determination of characteristic values, methods of specifying durability and sizes.This standard has been drafted on the assumption that the design requirements for transmission andtelecommunication poles will be left to the end-buyer and are not covered by Eurocode 5, which is for the design ofbuildings and civil engineering structures.This standard is for initially determining the characteristic values for a given population of poles, and additionallywhen there is a reason to suspect that the characteristic values for a population have changed.SIST EN 12511:2002
