Timber poles for overhead lines - Test methods - Determination of modulus of elasticity, bending strength, density and moisture content
This European Standard specifies methods of test to determine modulus of elasticity, bending strength, density and moisture content of solid wood poles for overhead transmission and telecommunication lines. It is applicable to both hardwood and softwood poles.
This standard covers only single poles under cantilever and/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 - Prüfverfahren - Bestimmung des Elastizitätsmoduls, der Biegefestigkeit, der Dichte und des Feuchtigkeitsgehalts
Diese Europäische Norm beschreibt Prüfverfahren zur Bestimmung des Elastizitätsmoduls, der Biegefestigkeit, der Rohdichte und des Feuchtegehalts von Vollholzmasten für Energieüber-tragungs-- und Fernmeldefreileitungen. Sie gilt für Laub- und Nadelholzmaste.
Diese Norm gilt nur für eingespannte einstielige Maste und/oder 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 der vorliegenden Norm nicht erfaßt sind; der Betreiber kann seine speziellen Anforderungen mit ergänzenden Anforderungen zu den in der vorliegenden Norm definierten vervollständigen. Dies betrifft Anforderungen an die Sicherheit, die Freileitungsanlage, die Handhabung, das Zubehör, die Hilfsmittel für die Errichtung und an die Arbeitsvorgänge einschließlich der Mastbesteigung.
Poteaux en bois pour lignes aériennes - Méthodes d'essai - Détermination du module d'élasticité, de la résistance à la flexion, de la masse volumique et de la teneur en humidité
La présente norme spécifie des méthodes d'essai permettant de déterminer le module d'élasticité, la résistance à la flexion, la masse volumique et la teneur en humidité des poteaux en bois massif destinés aux lignes aériennes de transmission et de télécommunication. La présente norme s'applique aussi bien aux poteaux en bois feuillus qu'en bois résineux.
La présente norme s'applique uniquement aux poteaux simples soumis à une charge en porte-à-faux et/ou à 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 à l'égard d'un certain nombre de facteurs relatifs à la sécurité, aux installations aériennes, à la manutention, aux équipements, aux machines d'installation et aux pratiques d'usage, y compris l'escalade.
