EN 13197:2011 (E) 6 4.2 Test plates housing
4.2.1 General The turntable's rim is provided with a number of housings to fix the test plates. These housings shall comply with the following requirements. 4.2.2 Dimensions They have to be sufficient to allow the use of the appropriate measurement equipment. The minimum required dimension on the parallel direction to the movement of the loading wheels is 190 mm, although the use of some commercial measuring equipment requires longer distances. 4.2.3 Location All of them shall be fixed at a position in the rim to provide a rolling-line defined by a diameter of 585 cm ± 5 cm measured by the central line of the contact area of tyre. The layout shall guarantee that the location of the test plates has no influence in the results. 4.2.4 Fixation system The fixation of the test plates allows the top of the test plates to be at the same level that the housing external part to avoid create jumping, a uniform rolling surface without skidding or vibration and an absolute immobility of the test plates on their housings. 4.3 Cleaning system The wear simulator shall have appropriate equipment in order to eliminate effectively and in a few wheel passages the particles that, potentially, could leave the film and to keep the tyres clean and cool; they may be:
brushes;
jet air;
vacuum cleaner; water and air atomizers;
others. NOTE 1 During the wearing process, some components of the road marking materials (mainly particles of drop-on materials) may leave the film and, if not removed, may adhere the tyres and cause an additional and uncontrolled wear. This effect may be especially serious when the materials under test are thermoplastics and the tyres, if not sufficient cool and clean, may become tacky as consequence of the adherence of thermoplastic binder.
NOTE 2 The test method may also specify additional cleaning possibilities such as to include an initial short cycle with the aim of removing in a first stage the particles badly adhered to the applied road marking and the possibility of allowing the tyres to wheel passages the road marking and the pavement (test plates without road marking material) alternatively. 4.4 Water dispenser The wear simulator shall have a water dispenser able to add water over the test plates. SIST EN 13197:2011
EN 13197:2011 (E) 7 4.5 Test room The wear simulator is located into a test room isolated and air-conditioned.
4.6 Wheels 4.6.1 General Stress load is created by the effect of a number of wheels rolling over the test plates. The stress load depends on the number of wheels, on the type of tyres, on the load itself, on the inflate pressure, on the support and steering angles and on the alignment.
4.6.2 Number of wheels The reference stress load shall be created by the effect of two pairs of wheels. Different numbers of wheels can be used, provided that they correlate with the results obtain with the reference stress load.
NOTE Wheels of the same pair are located in opposite position. 4.6.3 Type of tyres The approval of the specific commercial tyres shall be done by submitting the control plate (see 7.3) to a real run test, using the wheels to be tested, up to a minimum traffic class of P6 (see 8.5.3, Table 4). The tyres shall be approved if the result on the control plate does not deviate from the known and controlled characteristics in excess of the percentages listed in 8.3.
New tyres shall be used for each test. NOTE 1 For the selection of the tyres the following aspects are recommended:
dimensions: The tyres will have a commercial size
of 205/60, able to give an homogeneous rolled width of, at least, 150mm. pattern: symmetric (whenever possible). nature: specific commercial tyres.
NOTE 2 Manufacturers are continuously modifying both the nature and the pattern of the commercial tyres; therefore, it is not advisable to establish any specification. 4.6.4 Wheel load The wheel load on the turntable may range between 0 N and 4 000 N.
4.6.5 Inflate pressure The inflate pressure may range between 0 and 0,3 MPa. 4.6.6 Steering and support angles The fixation system of the wheels has to allow the adjustment of the steering angle with a tolerance of ± 10’and the support angle with a tolerance of maximum -20’. NOTE The steering angle can considerably influence the amount of abrasion of the marking material. The support angle influences in case of differenced diameters and velocities between inside and outside the tyres the nature of abrasion pattern. SIST EN 13197:2011
EN 13197:2011 (E) 8 4.6.7 Alignment The fixation system of the wheels has to allow small adjustments in the alignment in order to compensate the effects of different tyre’s patterns. NOTE Some patterns of the commercial tyres may cause – when the wheels are aligned – the presence of some narrow lines with lower abrasion. This effect may be compensated with slight changes on the alignment. 4.7 Measurements in relation to equipment
The following parameters shall be measured, controlled and recorded:
date and time; turntable speed;
turning direction;
room temperature; test plate surface temperature; load per wheel; number of wheel passages (wp); steering angle; support angle;
inflate pressure. The laboratory shall have available the necessary equipment and procedures to ensure the traceability of the measurements. 5 Test plates 5.1 General The road marking materials to be tested in the wear simulator have to be applied on test plates. The results are highly dependent on the substrate: roughness but also on the nature and size (for a reliable result a minimum surface of road marking material has to be tested).
5.2 Substrate nature The body of test plates shall be manufactured with materials of sufficient rigidity so that the surface texture is not modified during the test process and so that it can be handled without obvious bending or breaking up at temperatures up to 50 °C. When other than a bituminous material is used for manufacturing the test plates the surface shall be coated with approximately 50 g/m² of bitumen Type B 70/100 or similar. The bitumen may be applied in one or more coating of diluted bitumen in such a way that enough adherence of the bitumen to the substrate is achieved. SIST EN 13197:2011
EN 13197:2011 (E) 9 5.3 Roughness The roughness of the test plate surfaces, measured as texture depth in accordance with the method described in EN 13036-1, shall comply with some of the classes listed in Table 1. For CE marking purposes only classes RG1 and RG2 shall be used. The classes RG3 and RG4 are only for research purposes. Table 1 – Classes of roughness Class of roughness texture depth in mm according to EN 13036-1 RG1 ≤ 0,6 RG2 > 0,60 and ≤ 0,90 RG3 > 0,90 and ≤ 1,20 RG4 > 1,20
NOTE 1 For practical purposes a value in the middle of the classes should be chosen. A sample of test plates shall be submitted periodically to the test process in order to determine if after the test process they are still in the same class of roughness.
NOTE 2 Sometimes, to stabilise the texture of the test plates it is convenient to submit them to a preparatory wheel passages process. 5.4 Size (useful surface) The size of the test plates shall to be sufficient both for the complete contact area of the tyre to roll over and for the necessary measurements to be performed allowing the use of the appropriate measurement equipment. For testing a road marking material, the necessary number of test plates to complete a measurement area of, at least, 800 cm² shall be used.
NOTE The longer are the test plates (in one piece) the more reliable are the photometric measurements particularly for night-time visibility under wet and rain conditions. Test plates of 45 cm have shown good performance in these cases. 6 Sampling When samples are required for identification purposes, each road markind material, all components of a multiple component material, and drop-on materials shall be taken into account. NOTE 1 For certification purposes sampling shall be done by the test laboratory. NOTE 2 The participants can agree to include further specifications for sampling, such as quantities to sample. 7 Preparation of samples (application on the test plates) 7.1 General The test results depend on various factors related to the application of the road marking materials, mainly on the application instructions (type of application and quantities applied) on the direction of application (in relation to the wearing process and the direction of measurements) and on the drying or hardening conditions (conditioning).
A particular case is the preparation of a sample as a reference or control plate. SIST EN 13197:2011
EN 13197:2011 (E) 10 7.2 Application instructions 7.2.1 General The applicant shall specify the application instructions for the road marking system including all needed components and quantities of those, also the type of application. 7.2.2 Type of application In principal, road marking materials should be applied using the type of application (e.g. spray or extrusion) used in practice. Other methods of application, appropriate for laboratory conditions, may be used whenever they ensure the required layer thickness or weight and distribution (transversal and longitudinal) and whenever there are experiences of the testing laboratory that both types of application will produce the same results. The method and data of application shall be recorded in an application report. 7.2.3 Quantities applied (rate of application) The application shall be carried out in such a way that
the layer thickness and/or the layer weight and
the quantity of drop on materials remaining on the road marking to be tested.
When measured in accordance with the specifications given in 7.6.3 it does not differ by more than 10 % from the required quantities specified by the manufacturer. NOTE The remaining material on the road marking is relevant for performance information. The consumption may be relevant for cost information and the participating parties may agree its evaluation for this purpose.
7.3 Control plate (reference) At least one test plate of a standard material and with a standard road marking material shall be included in each test run for indication of correct procedure (control plate). The control plate is defined for each laboratory including the specifications of the material(s), the application instructions and the results to be achieved under the standard test conditions. If relevant for the intended use, the laboratory may define more than one control plate. The results of the control plate in each particular test shall be used as an acceptance or rejection criteria for the particular test. The successive results shall be used for determining the repeatability of the test method. 7.4 Test plate orientation (direction of application) The application on the test plates have to be carried out taking into account that the test plates have to be aligned in the wear simulator so that the road markings are parallel to the movement of the loading wheels relative to the test plates. 7.5 Conditioning
The prepared test plates shall be dried (or to harder) in a conditioned chamber at a temperature of 20 °C (± 5°C) and a relative humidity comprising between 45 % and 75 %. Test operation for paints will commence eight days, at the earliest, and twelve days, at the latest, following the application of test samples. The conditioning periode for water-based paints shall be one week more than solvent paints. For other products the minimum conditioning period is 48 h.

4.6.5 Inflate pressure It may range between 0 and 0,3 MPa. 4.6.6 Steering and support angles The fixation system of the wheels has to allow the adjustment of the steering angle with a tolerance of ± 10’and the support angle with a tolerance of maximum -20’. NOTE The steering angle can considerably influence the amount of abrasion of the marking material. The support angle influences in case of differenced diameters and velocities between inside and outside the tyres the nature of abrasion pattern. kSIST FprEN 13197:2010
FprEN 13197:2010 (E) 8 4.6.7 Alignment The fixation system of the wheels has to allow small adjustments in the alignment in order to compensate the effects of different tyre’s patterns. NOTE Some patterns of the commercial tyres may cause – when the wheels are aligned – the presence of some narrow lines with lower abrasion. This effect may be compensated with slight changes on the alignment. 4.7 Measurements in relation to equipment
The following parameters shall be measured, controlled and recorded:
date and time; turntable speed;
turning direction;
room temperature; test plate surface temperature; load per wheel; number of wheel passages (wp); steering angle; support angle;
inflate pressure. The laboratory shall have available the necessary equipment and procedures to ensure the traceability of the measurements. 5 Test plates 5.1 General The road marking materials to be tested in the wear simulator have to be applied on test plates. The results are highly dependent on the substrate: roughness but also on the nature and size (for a reliable result a minimum surface of road marking material has to be tested).
5.2 Substrate nature The body of test plates shall be manufactured with materials of sufficient rigidity so that the surface texture is not modified during the test process and so that it can be handled without obvious bending or breaking up at temperatures up to 50 °C. When other than a bituminous material is used for manufacturing the test plates the surface shall be coated with approximately 50 g/m² of bitumen Type B 70/100 or similar. The bitumen may be applied in one or more coating of diluted bitumen in such a way that enough adherence of the bitumen to the substrate is achieved. kSIST FprEN 13197:2010
FprEN 13197:2010 (E) 9 5.3 Roughness The roughness of the test plate surfaces, measured as texture depth in accordance with the method described in EN 13036-1, shall comply with some of the classes listed in Table 1. For CE marking purposes only classes RG1 and RG2 shall be used. The classes RG3 and RG4 are only for research purposes. Table 1 – Classes of roughness Class of roughness texture depth in mm according to EN 13036-1 RG1 ≤ 0,6 RG2 > 0,60 and ≤ 0,90 RG3 > 0,90 and ≤ 1,20 RG4 > 1,20
NOTE 1 For practical purposes a value in the middle of the classes should be chosen. A sample of test plates shall be submitted periodically to the test process in order to determine if after the test process they are still in the same class of roughness.
NOTE 2 Sometimes, to stabilise the texture of the test plates it is convenient to submit them to a preparatory wheel passages process. 5.4 Size (useful surface) The size of the test plates shall to be sufficient both for the complete contact area of the tyre to roll over and for the necessary measurements to be performed allowing the use of the appropriate measurement equipment. For testing a road marking material, the necessary number of test plates to complete a measurement area of, at least, 800 cm² shall be used.
NOTE The longer are the test plates (in one piece) the more reliable are the photometric measurements particularly for night-time visibility under wet and rain conditions. Test plates of 45 cm have shown good performance in these cases. 6 Sampling When samples are required for identification purposes, each road markind material, all components of a multiple component material, and drop-on materials shall be taken into account. NOTE 1 For certification purposes sampling shall be done by the test laboratory. NOTE 2 The participants can agree to include further specifications for sampling, such as quantities to sample. 7 Preparation of samples (application on the test plates) 7.1 General The test results depend on various factors related to the application of the road marking materials, mainly on the application instructions (type of application and quantities applied) on the direction of application (in relation to the wearing process and the direction of measurements) and on the drying or hardening conditions (conditioning).
A particular case is the preparation of a sample as a reference or control plate. kSIST FprEN 13197:2010
FprEN 13197:2010 (E) 10 7.2 Application instructions 7.2.1 General The applicant shall specify the application instructions for the road marking system including all needed components and quantities of those, also the type of application. 7.2.2 Type of application In principal, road marking materials should be applied using the type of application (e.g. spray or extrusion) used in practice. Other methods of application, appropriate for laboratory conditions, may be used whenever they ensure the required layer thickness or weight and distribution (transversal and longitudinal) and whenever there are experiences of the testing laboratory that both types of application will produce the same results. The method and data of application shall be recorded in an application report. 7.2.3 Quantities applied (rate of application) The application shall be carried out in such a way that
the layer thickness and/or the layer weight and
the quantity of drop on materials remaining on the road marking to be tested.
When measured in accordance with the specifications given in 7.6.3 it does not differ by more than 10 % from the required quantities specified by the manufacturer. NOTE The remaining material on the road marking is relevant for performance information. The consumption may be relevant for cost information and the participating parties may agree its evaluation for this purpose.
7.3 Control plate (reference) At least one test plate of a standard material and with a standard road marking material shall be included in each test run for indication of correct procedure (control plate). The control plate is defined for each laboratory including the specifications of the material(s), the application instructions and the results to be achieved under the standard test conditions. If relevant for the intended use, the laboratory may define more than one control plate. The results of the control plate in each particular test shall be used as an acceptance or rejection criteria for the particular test. The successive results shall be used for determining the repeatability of the test method. 7.4 Test plate orientation (direction of application) The application on the test plates have to be carried out taking into account that the test plates have to be aligned in the wear simulator so that the road markings are parallel to the movement of the loading wheels relative to the test plates. 7.5 Conditioning
The prepared test plates shall be dried (or to harder) in a conditioned chamber at a temperature of 20 °C (± 5°C) and a relative humidity comprising between 45 % and 75 %. Test operation for paints will commence eight days, at the earliest, and twelve days, at the latest, following the application of test samples. The conditioning periode for water-based paints shall be one week more than solvent paints. For other products the minimum conditioning period is 48 h.
