This document applies to the measurement of vertical wheel forces of railway vehicles in maintenance workshops and at manufacturing sites. It also deals with derived quantities that are used to describe the vehicle’s vertical wheel force distribution. The document defines the assessment and acceptance criteria for the measurement process. The requirements for this assessment support the specification, the design and the operation of the measurement process. It is considered that the measurements are made either statically or quasi-statically. This document is applicable to all railway vehicles. The commercial weighing of vehicles is not covered by the scope of this document, nor does it define in which cases the wheel forces of a vehicle will be measured.

1.1 This document specifies a direct measurement method for characterizing the surface roughness of the rail and wheel associated with rolling noise ("acoustic roughness"), in the form of a one-third octave band spectrum. This document describes a method for: a) selecting measuring positions along a track or selecting wheels of a vehicle; b) selecting lateral positions for measurements; c) the data acquisition procedure; d) measurement data processing in order to estimate a set of one-third octave band roughness spectra; e) presentation of this estimate for comparison with limits of acoustic roughness; f) comparison with a given upper limit in terms of a one-third octave band wavelength spectrum; g) the measuring system requirements. 1.2 It is applicable to the: a) compliance testing of reference track sections in relation to the acceptance test for noise emitted by railway vehicles; b) performance testing of track sections in relation to noise emitted by railway vehicles; c) acceptance of the running surface condition only in the case where the acoustic roughness is the acceptance criterion; d) assessment of the wheel surface condition as an input for the acoustic acceptance of brake blocks; e) assessment of the wheel and rail roughness as input to the calculation of combined wheel rail roughness; f) diagnosis of wheel-rail noise issues for specific tracks or wheels; g) assessment of the wheel and rail roughness as input to rolling noise modelling; h) assessment of the wheel and rail roughness as input to noise source separation methods. 1.3 It is not applicable to the: a) measurement of roughness (rail roughness, wheel roughness or combined roughness) using an indirect method; b) analysis of the effect of wheel-rail interaction, such as a “contact filter”; c) approval of rail and wheel reprofiling, including rail grinding operations, except for those where the acoustic roughness is specifically the approval criterion (and not the grinding quality criteria as provided in e.g. EN 13231-3); d) characterization of track and wheel geometry except where associated with noise generation.

This document gives design rules and requirements in order to ensure proper access, lighting, seating and exit of the driver’s cab. The different dimensions are based on the anthropometric data defined in EN 16186-1. The corresponding assessment methods are also included in this standard. It covers the following aspects: - dimension and interior layout; - door access, steps, floor characteristics; - seats dimension and clearance; - interior cab lighting; - emergency exit; - marking and labelling. This part of the EN 16186 series applies to driver’s cabs of Electrical Multiple Unit (EMU), Diesel Multiple Unit (DMU), Railcars, Locomotives and Driving trailers (Driving Coaches). NOTE 1 This European Standard applies to rolling stock in the scope of Directive 2008/57/EC [6]. This part of the EN 16186 series applies to driver's desks installed on the left, on the right, or in a central position in the driver’s cab. Due to cab space and resulting desk integration constraints, desk layout can vary. NOTE 2 Due to railway systems constraints, the level of comfort and accessibility provided to the persons outside the anthropometric range defined in EN 16186-1 may vary. Usually the operators manage the potential restrictions, if the driver uses the full range of seat positions (as defined in this standard) combined with extreme body dimensions (as defined in EN 16186-1). This document is not intended to be applicable for OTMs, tramways, metro and light rail vehicles. NOTE 3 For OTMs, see EN 14033-1 [11] and EN 15746-1 [17].

This European Standard, to be used together with EN ISO 4254-1, specifies the safety requirements and their verification for the design and construction of self-propelled, mounted, semi-mounted and trailed manure spreaders, provided with vertical or horizontal axes rotors rear spreader device or with vertical axes disc rear spreader device. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer. When requirements of this document are different from those which are stated in EN ISO 4254-1, the requirements of this document take precedence over the requirements of EN ISO 4254-1 for machines that have been designed and built according the provisions of this document. This European Standard, taken together with EN ISO 4254-1, deals with all the significant hazards, hazardous situations and events relevant to manure spreaders, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Table 1), excepting the hazards arising from: - vibrations of self-propelled machinery; - travelling function of self-propelled machinery; - overturning in regard to the protection of the operator at the driving station of a self-propelled machine; - hazards related to conveying devices other than those defined in 3.3.1 and 3.3.2, for example load push/push-off device. NOTE 1 Regarding roll-over protection for self-propelled agricultural machinery, see EN ISO 16231-1. NOTE 2 This European Standard is neither applicable to environmental hazards nor to road safety. Environmental aspects are dealt with in EN 13080. This European Standard does not apply to manure spreaders with laterally mounted spreading device as defined in 3.6. This European Standard is not applicable to manure spreaders which are manufactured before the date of publication of this document by CEN.
