22、2012CEN/TS 15597-2:2012 (E) 4 Introduction This document is meant to assess the demands made on mobile spreading machines operated in traffic. Spreading machines (spreaders/gritters) are to be operated in such way that homogeneous distribution of spreading media is given within the set spreading dos
23、age, width and spreading pattern track. Due to the different kind of thawing materials used and a lack of experience to detect the exact quantity of thawing material spread on the road, CEN/TC 337 decided to publish a Technical Specification giving the possibility to all the operators to test differ
24、ent methods to determine the precision of the spreading pattern. Therefore the test methods have not been specified in detail in this Technical Specification. But the required accuracy of the measuring methods is given. DD CEN/TS 15597-2:2012CEN/TS 15597-2:2012 (E) 5 1 Scope This Technical Specifica
25、tion gives the possibility to certify a model of vehicle-mounted or (trailer-)dragged spreading machines for winter service with standard parameters, leaving the possibility for the manufacturer to evolve performance. At the same time, information is given on the minimum content required for operati
26、ng manuals. This Technical Specification is valid for machines which are used to spread the following media: solid thawing media with or without pre-wetted media; liquid thawing media. The following points are not covered by this Technical Specification: requirements for registration and approval; r
27、equirements made by automobile manufacturers; requirements on safety these are dealt with in EN 13021. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the l

30、r types spreader types as defined by using different spreading parameters according to Tables 1 and 2 3.3 test materials test materials as defined in Clause 5 3.4 test test realised with different spreading parameters (dosage, spreading width and vehicle speed), for a machine model, a test material
31、and a spreader type DD CEN/TS 15597-2:2012CEN/TS 15597-2:2012 (E) 6 3.5 qualification qualification of a machine model that states the conformity to the requirements defined in this standard NOTE The compliance with these requirements is verified by a series of static and dynamic tests defined for a
32、 type of spreader and a test material. 3.6 test report document in which the whole conditions and test results for a qualification are recorded 3.7 technical certificate technical certificate that is set for a qualified machine model NOTE If several qualifications of the same model are realised with
33、 different combinations of “test material / spreader type“, the whole test results of the different qualifications will be reported on the same technical certificate. 3.8 measurement points whole measured data in the static test, which are calculated or set according to the frequency 3.9 outer strip

37、ypes are defined by using the following range of minimum and maximum parameters: spreading width, dosage and vehicle speed ranges. The dosages and quantity given for the different test materials are defined in Clause 5 (NaCl). Table 1 Spreader types for solid thawing media Type Spreading width m Spr

The sodium chloride (NaCl) has different granulometries according to the mine or production type, the humidit
40、y of these products is very variable too. For this reason, the test can be done with any kind of sodium chloride for solid material; the following characteristics shall be indicated in the report: NaCl content (%); humidity (%); granulometry (3 sieves minimum for a vacuum salt and 5 sieves minimum f
41、or rock salt and sea salt); anti-caking agent (nature and concentration). The characteristics of materials shall be determined in laboratory by using a sample of material used for the test. An official certificate of material delivered by material supplier shall be attached to the test report. DD CE
42、N/TS 15597-2:2012CEN/TS 15597-2:2012 (E) 8 The de-icing material shall be protected from atmospheric moisture agent, during storage, to avoid changes in the original characteristic during storage period. The salt solution (sodium chloride, calcium chloride, magnesium chloride) shall have a concentra
43、tion between 18 % and 23 % of weight. In case of spreader type for liquid thawing media the kind of salt solution (brine) used for test shall be described: sodium chloride, calcium chloride or magnesium chloride, or other de-icing material; salt concentration, in percentage of weight; density, in kg
44、/dm3. 6 Certification procedure 6.1 Principle of qualification procedure The qualification procedure of the spreaders includes two test types, one static and one dynamic. The static test enables assessment of the regularity of material flow and the accuracy of quantity, it is carried out with moving
45、 the spreader stationary. The dynamic test enables assessment of salt spreading pattern, it is carried out by driving the spreading vehicle during spreading operation on a measurement area. According to the type of spreader tested, the qualification procedure sets the functioning parameters of the m
46、achine. These spreading parameters are different for the static and dynamic tests. Each spreader type, in order to be qualified, has to meet the requirements of the two tests (static and dynamic). During a qualification, it is forbidden to modify the original calibration of the spreader. Any calibra
47、tion involves the cancellation of the current qualification procedure. The weighing equipment, for both tests, shall be certified with a precision of 1 %. The measurement area sizes shall be defined with a precision of 1 %. 6.2 Identification and requirements on spreader types A spreader type includ
48、es a spreader and a control box. The spreader and the control box have to be identified in the manufacturers production (for instance, model number) and shall be in accordance with the actual European standards. The modification of the components influencing the spreading performances defined in Ann
49、ex A involves the definition of a new machine model, a new procedure of qualification shall be realised for this new model. If the model can work with pre-wetted salt, the qualification shall be done with not pre-wetted and pre-wetted salt. The certificate will have the sentence “It can work with not pre-wetted and pre-wetted salt“ or “It can work with pre-wetted salt. It meets the requirements of CEN/TS 15597-2 only with pre-wetted salt“. If the machine cannot work with pre-wet
