Specifies steering system tests and performance criteria for evaluating the steering capability of rubber-tyred self-propelled earth-moving machines having a machine speed greater than 20 km/h. Applies to tractors, loaders, back-hoe loaders, excavators, dumpers, tractor-scrapers and graders. For the present, rollers, compactors and pipelayers are excluded.

Diese Europäische Norm legt Lenkanlagenprüfungen und Leistungskriterien zur Beurteilung des Lenkvermögens von gummibereiften, selbst fahrenden Erdbaumaschinen fest, die für eine Fahrgeschwindigkeit, ermittelt nach ISO 6014:1986, über 20 km/h ausgelegt sind.
Sie gilt für Schlepper, Lader, Baggerlader, Bagger, Muldenfahrzeuge, Scraper und Grader, die entweder mit Muskelkraftlenkung (ohne Fremdhilfe), Hilfskraftlenkung oder Fremdkraftlenkung ausgerüstet sind, wie in EN ISO 6165:2006 definiert.
Diese Europäische Norm schließt Walzen, Bodenverdichter und Rohrleger aus.

Engins de terrassement - Engins équipés de pneumatiques - Systèmes de direction (ISO 5010:1992 modifié)

La présente norme européenne prescrit les essais et les critères de performance pour l’évaluation de la capacité du système de direction des engins de terrassement automoteurs équipés de pneumatiques, dont la vitesse au sol, déterminée conformément à l'ISO 6014:1986, est supérieure à 20 km/h.
Elle est applicable aux tracteurs, chargeuses, chargeuses-pelleteuses, pelles, tombereaux, décapeuses automotrices et niveleuses, tels que définis dans l'EN ISO 6165:2006, équipés de systèmes de direction manuelle, assistée, ou à servodirection.
La présente norme européenne exclut les rouleaux, les compacteurs et les tracteurs poseurs de canalisations.

Erdbaumaschinen - Radfahrzeuge - Lenkvermögen (ISO 5010:1992 modifiziert) This European Standard was approved by CEN on 30 November 2013.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same status as the official versions.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United Kingdom.

Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC . 15
3.2.1 normal steering power source means for providing power to effect steering in either power-assisted or fully powered steering systems, for example, hydraulic pump, air compressor, electric generator 3.2.2 emergency steering power source means for providing power to the emergency steering system, for example, hydraulic pump, air compressor, accumulator, battery 3.2.3 failure of normal steering power source complete and instantaneous loss of a normal steering power source output. It is assumed that not more than one failure will occur at the same time 3.3 steering control element manual control means by which the operator provides muscular power inputs to the steering systems to effect the desired steering of the machine, including the typical steering-wheel or any equivalent manual control means 3.4 steering effort necessary force exerted by the operator on the steering control element in order to steer the machine 3.5 steering angle total displacement angle between the front wheels and the rear wheels as they move about one or more vertical steering axes from their normal straight-ahead condition to a turned condition Note 1 to entry: The steering angle for multiple axle machines is determined between the wheels at the farthest forward and the farthest rearward axle. Note 2 to entry: Ackermann steering inherently has a greater steering angle on the side of the machine towards the inside of the turn as compared to the wheels on the outside of the turn. Therefore, where Ackermann steering is involved, the location of the steering angle measurement also needs to be specified. A steering angle accomplished by a combination of geometries incorporating Ackermann steering is included, and also requires the location of steering angle measurement to be specified. 3.6 tyre circle outer tyre clearance diameter determined in accordance with Clause 9 3.7 working circuit pressure that nominal pressure applied to the specific circuit by the pump(s) 4 General requirements The following requirements apply to all steering systems within the scope of this European Standard. 4.1 The normal steering control element provided for the operator shall continue in all circumstances to be the steering control means of the operator.
