Machines with an operating mass less than 1 500 kg are not required to have a cab. Machines with an operating mass greater than or equal to 1 500 kg shall be equipped with a cab, unless the foreseeable adverse weather conditions allow all-year operation without a cab (negotiated between manufacturer and user). Machines shall be equipped with a cab and a contamination protective system if the machine is intended for use in unhealthy environments, e.g. contaminated areas (negotiated between manufacturer and user). See 5.14.1. If a hazard due to projection of splinters exists, e.g. operation with a hydraulic- or demolition-hammer, an adequate protection such as bullet proof glass, mesh guard or an equivalent protection is required. 5.3.1.2 Minimum space The minimum space available to the operator shall be as defined in !EN ISO 3411:2007" (except as amended in 5.3.2.5). SIST EN 474-1:2007+A4:2014

The minimum dimensions given in Table 1 are also required for machines having a front or rear window which are located (in an opened position) above the operator's seat. 5.3.2.6 Heating and ventilation system If a heating system is fitted it shall either: a) comply with !ISO/DIS 10263-4:2007", or b) have the capability of increasing the temperature of the air inside the cab and maintain a temperature of + 18°C at expected ambient temperature the machine is intended for. The minimum capacity of the heating system shall have a ∆T of 25°C (∆T of 25 K) within 30 min. The test shall run starting with the engine at working temperature as specified by the manufacturer. Measurement of the system capacity shall be made at three points. The three points shall be located in a vertical plane through the SIP and parallel to the longitudinal axis of the machine as follows (see Figure 3): 1) at filament position centre-point as defined in ISO 5006:2006; 2) at the SIP as defined in EN ISO 5353:1998; 3) 100 mm above floor plate and 600 mm in front of SIP. SIST EN 474-1:2007+A4:2014

Figure 3 — Location of measuring points c) Alternatively, the heating capacity can be determined by calculation. The ventilation system shall be capable of providing the cab with filtered fresh air at the minimum of 43 m3/h. The filter shall be tested according to !ISO/DIS 10263-2:2007". NOTE The filter element selection depends on the intended operating environment conditions. 5.3.2.7 Defrosting system Machine with a cab shall provide facilities to defrost the front and rear window(s), for example by means of a heating system or a particular defrosting device. NOTE A testing method of windscreen defrosting system is described in !ISO/DIS 10263-5:2007". 5.3.2.8 Pressurisation system Where a cab is provided with a pressurisation system, it shall be tested according to
!ISO/DIS 10263-3:2007" and shall provide an interior relative pressure of at least 50 Pa. 5.3.2.9 Doors and windows Doors, windows and flaps shall be securely held in their functional positions; measures shall be taken for preventing inadvertent opening. Doors shall be retained at their intended operating position(s) by a positive engagement device. A primary opening designed to be held securely open as an intended operating position, shall be releasable from the operator's station. Windows shall be made of safety glass or other material which provides similar safety performance (see e.g. ECE R43). Roof windows do not need additional mechanical safeguarding. The front and rear window(s) shall be fitted with motorised windscreen wiper(s) and washer(s). The tank of the window washer(s) shall be easily accessible. SIST EN 474-1:2007+A4:2014

stops). " 'In the case of hydraulically assisted variable gauge undercarriage, the controls shall be located in the operator's station.( 5.5.2 !Starting/stopping system" !The starting/stopping system of earth-moving machinery shall be provided with a starting/stopping device (e.g. key) and shall comply with ISO 10264:1990 or have a similar protection against unauthorized use. Earth-moving machines shall be so designed that hazardous movement of the machine or its working equipment and/or attachment shall not be possible without action on the controls whilst starting/stopping the engine. If the visibility from the operator's station to the rear by direct or indirect view cannot be achieved in accordance with 5.8.1, the machine shall be equipped with an acoustic and/or visual warning signal activated automatically when the reversing command is given, combined with a delay in starting the reverse movement, leaving sufficient time for an exposed person to leave the danger zone. NOTE When drafting this text it was not possible to define clear criteria for the necessary delay time as it depends on different parameters. In the idea of the drafters a delay of 3 s (that may be achieved completely or in part in the reaction time of the machine) will in general be appropriate. " 5.5.3 Inadvertent activation !Controls, which can cause a hazard due to inadvertent activation, shall be so arranged or deactivated or guarded as to minimise the risk, when the operator gets into or out of the operator's station." The deactivation device shall either be self-acting or acting by compulsory actuation of the relevant device. 5.5.4 Pedals Pedals shall have an appropriate size, shape and be adequately spaced. The pedals shall have a slip-resistant surface and be easy to clean. If the pedals of an earth-moving machine have the same function (clutch, brake, and accelerator) as on a motor vehicle, they shall be arranged in the same manner to avoid the risk of confusion. 5.5.5 Emergency attachment lowering If the engine is stopped it shall be possible to: a) lower the equipment/attachment to the ground/frame; b) see the equipment/attachment lowering from the operator actuating position of the lowering control; c) release the residual pressure in each hydraulic and pneumatic circuit, which can cause a risk.
