11、 of floor coverings used in workplaces and working areas where there is a risk of slipping. In addition, this standard specifies a method of measuring the volume of the displacement spaces in floor coverings with profiled surfaces. 2 Normative references The following documents, in whole or in part,

DIN 51130:2014-02 5 4 Principle 4.1 Slip resistance A tester wearing testing footwear walks forwards and backwards in an upright position across the floor covering to
19、 be tested, which is initially in a horizontal position and then gradually tilted until the acceptance angle has been reached. The acceptance angle is determined using a floor covering coated with lubricant. The mean acceptance angle reached is used to classify the degree of slip resistance. Subject
20、ive influences on the acceptance angle are limited by means of a calibration procedure. 4.2 Displacement space The test specimen is levelled out by filling the profile cavities with paste until this is flush with the surface. The mass of the test specimen is measured before and after this process. T
21、he volume of the displacement space is calculated from the difference in mass and the density of the paste. 5 Testing of slip resistance 5.1 Apparatus and test equipment 5.1.1 Testing footwear The tester wears testing footwear with an outsole2)of nitrile rubber with a Shore hardness of A/73 5 (accor
22、ding to DIN EN ISO 868) with a profile as in Figure 1. After the completion of the tests, the soles of the testing footwear shall not remain in an oil bath for storage. The soles are to be thoroughly cleaned and the oil removed, but without the use of any detergents or hydrotreated light naphtha, an
23、d stored in a dry place. Figure 1 Outsole of the testing footwear 5.1.2 Test apparatus with safety equipment For the test apparatus a flat warp resistant platform shall be used with a width of approximately 600 mm and a length of approximately 2 000 mm. In the longitudinal direction, the ramp shall
24、be adjustable to an incline of 0 up to approximately 40 (see Figure 2). The lifting speed of the drive shall be such that the angular velocity of the ramp is not more than 1/s. The tester shall be able to control the movement of the ramp, with the ability to move it up or down either continually or
25、in incremental steps of 0,5. There shall be an angle measuring device attached to the test apparatus that is capable of indicating the angle of inclination to the horizontal to an accuracy of 0,2. The test apparatus shall be constructed such that the angle of inclination does not fluctuate by more t
26、han 1 when walked along. The angle measuring device display is to be positioned such that the tester is not able to see it while the test is being performed. 2) Footwear with sole form LeipzigV73-SP can be obtained through Bergmann Schuhfertigung GmbH, Schravelener Niersweg 5, 47626 Kevelaer.

DIN 51130:2014-02 6 To ensure the safety of the tester, handrails are to be installed on each longitudina
28、l side of the test apparatus. The tester is also to be protected from falls by the use of appropriate safety equipment (safety harness and fall protection system).

The oil is to be stored in a tightly closed container to prevent
30、 changes in viscosity. 5.1.4 Flooring test piece The flooring test piece measuring approximately 100 cm 50 cm is to be obtained from the floor covering to be tested. The floor covering to be tested shall either be self-supporting or comprise a warp-free sheet with a flat underside, or else shall be
31、affixed to flat, resilient, warp-free material. The surface to be tested shall be easily identifiable as such or be clearly marked. Floor coverings with directionally-oriented profile or roughness are to be tested in such a manner that the orientation producing the lowest slip resistance is in line
32、with the walking direction. This is to be determined in preliminary tests. DIN 51130:2014-02 7 Floor coverings made up of individual rectangular pieces without directionally-oriented profile or roughness are to be positioned with the longitudinal side in the walking direction. The surface of the flo
33、or covering shall be clean for the test and free from manufacturing residues, separating agents, or flashes, for example. The preparation of the flooring test piece from the floor covering shall be done in a manner consistent with the way this type of covering is used in practice. 5.2 Calibration (s
34、election and training of the testers) There are three standard floor coverings available for the calibration method, (St-I, St-II and St-IIIA)3), whose acceptance angles have undergone extensive testing and have been specified as standard acceptance angles S,St-I, S,St-II and S,St-IIIA(see Table 1).
35、 The tester walks across each of the standard floor coverings three times before the test is carried out according to 5.3. The mean values KSt-I,j, KSt-II,j and KSt-IIIA,jare calculated from the resulting calibration acceptance angles determined by this pre-test. The individual corrections St-I,j, S
36、t-II,j and St-IIIA,jare obtained from the respective difference between these mean values and the standard acceptance angles. The critical difference, CrD, characterizes the range of variation of measured values within which differences randomly occur for either measurements on the same object in di
37、fferent laboratories or during different measurements in the same laboratory. The critical differences, CrD95, have been determined for the three standard floor coverings for a significance level*) of 95 % on the basis of the reproducibility limits and repeatability limits as in DIN ISO 5725-2 or DI
38、N ISO 5725-5. Two testers are required for testing the floor coverings to be evaluated. The calibrated acceptance angles determined for the standard floor coverings apply here KSt-I,1, KSt-II,1 and KSt-IIIA,1 and respectively, KSt-I,2, KSt-II,2 and KSt-IIIA,2as well as the individual corrections St-
39、I,1, St-II,1 and St-IIIA,1 and respectively, St-I,2, St-II,2 and St-IIIA,2. Table 1 Standard acceptance angle and critical differences Standard floor covering S, iCrD95St-I 08,7 3,0 St-II 17,3 3,0 St-IIIA 27,3 3,0 If the individual corrections St-I,j, St-II,j and St-IIIA,jfall within the critical di
40、fferences, they will be included in the analysis, but if they fall outside the range, the responsible tester will be excluded from the test. This person shall be replaced by another tester the same day. 3) Information regarding sources of supply of the three standard floor coverings can be obtained
41、from DIN-Normen-ausschuss Materialprfung (NMP), Burggrafenstrae 6, 10787 Berlin. *) Translators note. The term “confidence level” is probably meant here, not the “significance level”.

A.3 Evaluation a) The correction Djfor the flooring test piece, depending upon the mean value 0,j, is calculated according to the
43、 equations in Table 1. b) The individual result of test person j is calculated as follows: jj,jD+=0 (A.3) A.4 Classification The end result of the test by 2 testers is: 221ges+= (A.4) and results in the assignment to a class according to Table 3. DIN 51130:2014-02 12 Annex B (informative) Outsoles o
44、f the testing footwear Exposure to motor oil over longer periods as well as walking upon floor coverings with sharp surfaces can lead to changes in the sole of the test shoe. These changes can be determined optically or by calibration. Sanding the surface of the soles with unused sandpaper of grain 320 carbon silicide can remove these changes. After the surface of the soles is sanded, the sandpaper dust is to be removed and a test person shall carry out a calibration.
