This document (EN ISO 16231-2:2015) has been prepared by Technical Committee ISO/TC 23 “Tractors and machinery for agriculture and forestry” in collaboration with Technical Committee CEN/TC 144
6、“Tractors and machinery for agriculture and forestry”. The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (DIN Standards Committee Mechanical Engineering), Working Committee NA 060-16-30 AA Einzelthemen of Section Landtechnik. Stakeholders were involved in t
7、he development of the standard. This standard contains specifications giving detail to the essential requirements set out in Annex I of the “Machinery Directive”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standar
8、d serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of
9、 the Machinery Directive (“presumption of conformity”). The International Standards referred to in Clause 2 and the Bibliography, and which have been taken over as European Standards have been published as the corresponding DIN EN ISO Standards with the same number. Where the International Standards
10、 and documents referred to are not also DIN ISO Standards with the same number, there are no national standards available.

36、 (E) DIN EN ISO 16231-2:2016-08 4 IntroductionSelf-propelled agricultural machinery with a ride-on operator (driver) can be exposed to the hazard of rolling or tipping over during the intended operation. A risk assessment is used to determine whether this hazard is to be considered in case of a spec
37、ific machine and the protective measures to be used in order to avoid or minimize this hazard for the ride-on operator.The risk assessment considers the operating conditions in which the machine is intended to be used, the physical properties of the machine, and the required skills to operate the ma
38、chine as well as any other parameter which can have an impact on the risk for roll- or tip-over.EN ISO 16231-2:2015 (E) DIN EN ISO 16231-2:2016-08 5 1 ScopeThis part of ISO 16231 specifies a method to determine the centre of gravity of un-laden self-propelled machines, a method to determine the cent
39、re of gravity of laden machines and combinations with attachments, and methods to determine the static overturning angle.NOTE Requirements related to self-protective structures and ROPS are to be dealt with in a separate International Standard.2 Normative referencesThe following documents, in whole

45、e and to calculate the centre of gravity of the un-laden machineThe centre of gravity of the un-laden machine is determined by means of scales and support stands (see Tables 1 and 2 and Figures 1, 2, and 3).4.2 Remarks and items to observe during this procedure4.2.1 Follow the procedure as outlined
46、in ISO 789-6; this method is based on the increasing load on the supporting axle when the other axle is lifted and supported on a certain height; the lifting angle and the increased load on the scale allow determination of the height of the COG.4.2.2 It is recommended to use steel wheels in order to
47、 avoid deviations due to changing wheel radius under changing load conditions. For calculation of the COG with the actual tires, see 4.3.Any suspension system shall be locked. If locking the suspension system is not possible, then inflate all tires up to the maximum permissible pressure as specified
48、 by the tyre manufacturer. The difference in radius of the wheels on the fixed axle between horizontal and raised position shall not be higher than 1,5 % of the wheel radius.4.2.3 Ensure that the plane of the scale is horizontal and flush with the ground plane.4.2.4 Wheels on the scale shall be free to rotate, in order to exclude tangential forces on the tires. Therefore, the parking brake shall not be applied and the gearbox shall be in neutral or th
