EN 15429-2:2012 (E) 3 Foreword This document (EN 15429-2:2012) has been prepared by Technical Committee CEN/TC 337 “Winter maintenance and road service area maintenance equipment”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2013, and conflicting national standards shall be withdrawn at the latest by June 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. Generally, all surface cleaning machines – sweepers, are designed to clean paved surfaces of varying textures associated with areas exposed to vehicular traffic, pedestrians and those within industrial complexes.
Most of these sweepers are equipped with sweep gear to scarify debris with a pick-up system that collects and conveys the spoil into a hopper. This hopper can be discharged at dumping grounds, unloading stations, into containers or at refuse transfer stations. Sweeping applications are mainly related to the physical size and dimensions of the sweeper. Sweepers of larger dimensions are designed to operate mainly on streets, highways, motorways, large parking areas and within industrial complexes. Sweepers of smaller dimensions are designed for the cleaning of inner town streets, pedestrian zones, pavements, bicycle lanes, car parking facilities market places and within industrial plants etc. Manœuvrability is one of the main features of this category of sweeper. Depending on the dimensions, sweeping attachment equipment (e.g. equipment temporally mounted on multi-purpose carrier vehicles or other machines) may be used in similar applications as above. Additional equipment for specialised cleaning applications; that may be attached to a sweeper is not covered by this standard. This document (EN 15429-2:2012) is part of a series of documents made up of the following parts: EN 15429-1, Sweepers - Part 1: Classification and Terminology; EN 15429-2, Sweepers - Part 2: Performance requirements and test methods; prEN 15429-3, Sweepers - Part 3: Efficiency of particulate matter collection - Testing and Evaluation; prEN 15429-4, Sweepers - Part 4: Symbols for operator controls and other displays. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: 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 the United Kingdom.

As this value is purely theoretical, it may be unlikely to be achieved in use. 3.6 maximum sweeping speed a speed expressed in m/s and/or km/h declared by the manufacturer related to a foreseen sweeping application and/or test 3.7 work mode condition when the sweeper is conducting cleaning/sweeping activities when used as intended and under the conditions foreseen by the manufacturer 3.8 travel mode condition when the sweeper is moving between work sites and being driven in a similar way to that of a typical automotive road vehicle 3.9 prime mover primary power source be it; an internal combustion engine (diesel/petrol/gas), electric motor or hybrid drive system providing the principal power sources for work and travel mode functions. Note 1 to entry: Some sweepers may employ separate prime movers for propulsion and for driving the sweeping mechanisms. 3.10 truck/carrier vehicle base vehicle on to which the sweeper equipment is mounted, the sweeper equipment may be in some cases powered by the truck/carrier vehicle prime mover via power-take-off facilities or similar 4 Performance requirements and test methods 4.1 Theoretical sweeping capability A theoretical value, expressed in m2/h, derived from a calculation of the product of the maximum sweeping width and the manufacturer’s declared maximum sweeping speed. 4.2 Sweep ability 4.2.1 Performance Sweep ability is the maximum sweeping speed expressed in m/sec and/or km/h. The value is derived from a test method described in 4.2.2. 4.2.2 Test method Sweep ability shall be derived from a sweeping test, where a test material; composing a dry mixture by weight of 65 % washed sand (< 2 mm), 15 % gravel/grit (2 mm to 8 mm) and 20 % calcium carbonate, shall be spread at a rate of 700 g/m2 on to a dry smooth paved test surface in a zone extending at least 25 m long and SIST EN 15429-2:2013
EN 15429-2:2012 (E) 6 by 60% of the sweeper’s maximum sweeping width wide (this sweeping width would be the same value as used for the calculation in 4.1). The maximum sweeping speed would be the speed where the sweeper collects at least 90 % of the test material, the performance assessment may be judged visually. 4.3 Air flow capability 4.3.1 Performance Sweepers that use pneumatic means to collect and transport swept debris to the collection hopper require sufficient air velocity within the duct communicating with the pick-up device and hopper for satisfactory conveyance. Air movement is usually performed by an exhausting means, e.g. by a fan extracting air from the hopper. The air velocity within the duct and its cross sectional area has a direct correlation with the volume of air movement. Air velocity within the duct shall be expressed as m/sec. Volume of air movement within the duct shall be expressed as m3/sec, calculated as the product of the average velocity and the duct’s cross section expressed in m2. Air temperature, atmospheric pressure and the depression within the duct all affect the air density and flow characteristic, hence, any declared values shall be expressed in standard conditions of 20 °C and at 101,3 kPa atmospheric pressure. The effects of changes in relative humidity also affect air density, but as the effect is minimal, variance affects can be disregarded. Performance shall be advertised at 50% relative humidity with the proviso that tests are conducted in dry weather conditions. If adverse weather conditions are expected then tests shall be aborted.
The following information shall accompany the air flow capability declaration: sweeper - model/type; declaration expressed in m3/sec at 20 °C and at 101,3 kPa atmospheric pressure; settings and running speeds. 4.3.2 Test method The average air velocity within the duct may be measured using suitable means. Prior to any test, the machine shall be inspected to ensure that it is in good working order, clean and that any filters and/or communicating ductwork are free of restrictions and or blockages. During tests, the machine shall be set up according to the manufactures recommended settings. In addition, a record of these settings and running speeds shall accompany the performance results. Annex A describes a technique to measure duct velocity using the Pitot tube method.
4.4 Conveyor or elevator capability 4.4.1 Performance Machines that employ a mechanical means to transfer swept debris to the collection hopper may use a conveyor or elevator system (see figure 1). These systems may be of typical designs arranged vertically or inclined using a number of elevating catchments, e.g. flights/ribs on a conveyor belt, flights dragging up an inclined ramp or other similar mechanisms. In each case, the catchment (C) has a calculated volume in its transfer position, gauged when loaded with dry sand having an angle of repose of 35°. The conveyor system will have an operating speed where the catchment discharge (Cd) rate and its volume can be equated to a maximum loading capability – VMLC, expressed in m3/min. Performance is assessed by calculation. The following information shall accompany the conveyor or elevator capability declaration: sweeper - model/type; SIST EN 15429-2:2013

EN 15429-2:2012 (E) 8 4.5 Fuel consumption 4.5.1 Performance Sweepers may be powered by a single prime mover – known as single-engine machines, providing power for propulsion and for driving the sweeping/collection mechanisms during work mode. Alternatively, separate prime movers may be used solely for propulsion and solely for driving the sweeping/collection mechanisms, typically in the case of truck mounted sweepers – these are known as twin-engine machines. The former single-engine variety is typical of self propelled sweepers though there are also varieties of truck mounted sweeper that are single-engine machines where the sweeping mechanisms are driven via power-take-off systems that are engaged in work mode.
In the case of attached sweeping equipment, the sweeping/collection mechanisms may have their own prime mover or be driven by power-take-off facilities from the carrier vehicle. Fuel consumption declaration in these cases shall be according to the closest similarity to either of the other two other classification type of sweeper. An example test report of the fuel consumption is given in Annex B. Table 1 shows prime mover configuration according to machine type.

Fuel consumption(s) shall be declared in litres per hour (l/h) rounded to the first decimal point and derived from the quantity of fuel used from an average of three test cycles as defined in Figure 2. In the case of truck mounted sweepers and attached sweeping equipment of the twin-engine variety, the fuel usage of each internal combustion engine shall be declared separately. The fuel used by the non-propulsion internal combustion engines would only be recorded during the sub-test 2) with the quantity used representing the hourly consumption. The following information shall accompany the fuel consumption declaration: Sweeper - model/type (and truck/carrier vehicle details if applicable); maximum travel speed (km/h) and work speed (km/h); details of sweeping-gear, swept width, number and details of brushes in use; power setting(s) specifically declared by manufacturer in their operator's manuals; total fuel consumption expressed in litres per hour (l/h).

EN 15429-2:2012 (E) 9 4.5.2 Test method The test shall be conducted under the following conditions and method shown in Figure 2: Prior to the test, the sweeper shall be prepared in a ‘ready for work’ condition and laden to at least 75% of its maximum permitted mass - inc. fuel, water, driver and with the hopper partially loaded with suitable material. All internal combustion engines and associated driven equipment shall be at their normal operating temperatures prior to test. During the work mode sub-test 2) all sweeping/collection mechanisms shall be in their working positions and work at their specific power ratings stated by the manufacturer in their operator's manual. No sweeping performance requirement is required. The test shall be conducted on a flat, paved, clean test track with any gradients less than 2 %. Maximum speeds of sub-test 1) and maximum work speed of sub-test 2) shall be constant within a tolerance of ± 10 % and recorded in the test report (see Annex B). Acceleration activity shall be conducted as quickly as possible. Braking activity shall be conducted rapidly and in a safe manner. Fuel used by each prime mover shall be measured with a ± 3 % accuracy for example using flow meters or graduated containers. Measurements before and after test shall be conducted on a level surface. NOTE Fuel density, calorific values and temperature can effect fuel consumption and may lead to variation in results Weather conditions shall be within an ambient temperature range 10 °C to 25 °C. In the case of the prime movers driving solely the sweeping/collection mechanisms, fuel usage measurement is only recorded during the work mode sub-test 2). SIST EN 15429-2:2013

EN 15429-2:2012 (E) 11 4.7 Kerb climbing and clearance capability 4.7.1 Performance The tractive effort of the sweeper’s propulsion system and the approach angle when mounting a kerb or step affects its ability to mount it and generally, the more acute the angle of approach the greater the difficulty. Performance shall be expressed as the maximum step height (mm) the sweeper can mount when approaching from a static position, at alternate angles of 30° and 60°. The mass of the machine may affect the achievement and performance shall be declared at the maximum permitted mass.
Physical constraints where a structural element of the sweeper may impact a kerb shall be declared as the limiting factor in defining maximum kerb/step height. Impact with flexible elements, for example brush tines and flexible curtains etc. shall be excluded. The following information shall accompany the kerb climbing and clearance capability (see figure 3) declaration: sweeper - model/type and maximum permitted mass; wheel/tyre size; any structural element limitation; kerb height expressed in mm as the lesser of:

4.7.2 Test method The sweeper under test shall approach the kerb from a static position and from a distance of at least 1.5 times the machine’s length away from kerb and at angles of 30° and 60° to the kerb with the steering set in the straight-ahead position. The test is complete once all wheels have mounted the kerb without impact with any structural element, save impact with brush tines or flexible curtains. The test kerb shall have initial start height of 120 mm and ideally be of artificial construction where it can be increased in height specifically for the test. If the initial test kerb height of 120 mm is impractical then it may be reduced to allow a test to be conducted. The sweeper shall be laden to its permitted maximum mass and equipped with tyres in a new condition and pressurized according to the sweeper manufacturer’s recommendation. For sweepers with fluid power transmission systems, the drive and prime mover controls may be moderated to adjust the approach speed and climbing ability while each wheel climbs the kerb. All-wheel drive systems when fitted may be employed. For sweepers with mechanical transmissions, the transmission shall be set in its lowest drive gear and the engagement mechanism and prime mover control may be moderated to adjust the approach speed and climbing ability while each wheel climbs the kerb. Differential locks and all-wheel drive systems when fitted may be employed. 4.8 Ramp, approach and departure angles These are as defined in ISO 612:1978, definition numbers; 6.9, 6.10 and 6.11 respectively. Angles shall be defined with all sweeping gear in their stowed positions. All conditions are where the mass of the machine is at its permitted maximum.
