The method is

20、 applicable to polyvinyl chloride floor coverings with smooth surfaces. It can be used to determine the wear resistance of surfaces against abrasion and particularly for ranking different wear layer types within one type of product. It is not appropriate for comparing the wear resistance of differen

21、t materials, e.g. rubber and polyvinyl chloride. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dat

22、ed references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 436, Resilient floor coverings Determination o

23、f density. 3 Principle A special wear testing apparatus simulates the rotating movements combined with sliding stress which are caused by the shoes of users on floor coverings, e.g. close to doors, cupboards, wash-basins etc. The abrasive medium is emery paper. Alternating stress cycles are carried

24、out with emery paper and leather and indentation stress with steel tacks is part of each cycle. 4 Definition For the purposes of this European Standard the following definition applies. wear loss of material from the surface of a floor covering 5 Apparatus and materials 5.1 Wear testing apparatus, w

25、ith the essential dimensions shown in Figure 1, consisting of the following. 5.1.1 A roller table, which moves horizontally to and fro (i.e. one double travel movement) along a (106 0,5) mm path. The number of double travel movements is (40 1) per minute. 5.1.2 A rotating clamping plate for the test

26、 piece, revolving at (4,0 0,1) revolutions per minute mounted on the roller table. 5.1.3 A pendulum, weighing (17 0,1) kg with two swivel segments with cylindrically arched undersides, radius 225 mm (abrading segment and milling segment). The abrading segment is covered with leather and fitted with

27、devices to stretch emery paper over this surface. 5.1.4 Two roller bearings, one fixed to the stand which moves in a track in the pendulum and the other fixed to the pendulum which moves in a track mounted on the table. Both ensure that the movements of roller table and pendulum are linked. 5.1.5 A

28、suction and blower device, with apertures which cover the test area. EN 660-1:1999 4 BSI 23 July 2003 5.2 A metal template, weighing (430 20) g, as shown in Figure 2, for the milling segment. On the underside at both ends metal strips 2 mm thick and 106 mm long are fixed to form an area of 170 mm by

29、 106 mm in which a leather sole can be glued. 5.3 A device in which emery paper can be fixed, and which can be installed into the clamping plate instead of the test piece. 5.4 Emery paper, with grain size No. 50. The description of this specially produced paper is P50 WPE 221. Each delivery of emery

30、 paper shall be subjected to a control test in accordance with Clause 9. 5.5 Leather sole, pit-tanned 170 mm by 106 mm with thickness (5,5 0,5) mm, density (1,04 0,08) g/cm 3and Shore-D-Hardness (60 5). 5.6 Plane-parallel plate, thickness 10 mm with steel tacks as shown in Figure 3. The 89 tacks pro

31、ject 3 mm above the surface of the plate. 5.7 Square metal support plates, for the specimen with edge length of (200 0,5) mm, e.g. duralumin 4 mm thick. 5.8 Appropriate adhesive, to glue the specimen flat upon the support plate or double-sided adhesive tape. 5.9 Hand brushes, soft-hair and hard bris

32、tle. 5.10 Balance, with an accuracy of 0,1 mg.

Figure 3 Plate with steel tacksEN 660-1:1999 8 BSI 23 July 2003 6 Sampling and preparation of specimens Take a representative sample from the available material. Take three square specimens, with edge length

34、 200 mm, from the sample. For sheet material take one specimen from the middle of the sample and the second and third approximately 150 mm from the edges. Check the flatness of the metal support plates (see 5.7) by putting a steel rule diagonally on the plates. Ensure that there is no gap greater th

35、an 0,1 mm between the rule and the surface of the plate. Glue the specimens to the metal plates (see 5.8). Ensure that the whole area of the support plate is covered by the adhesive or the tape. 7 Conditioning Condition the three specimens to equilibrium at a temperature of (23 2) C and (50 5) % rel

36、ative humidity (standard climate). Equilibrium is reached when the difference between two measured masses in an interval of 48 h is no more than 0,002 g. Maintain these conditions when carrying out the test. 8 Preparation of the leather sole Glue a leather sole (see 5.5) to the metal template (see 5

37、.2) and fix this template to the milling segment of the pendulum (see 5.1.3). Fix the device with emery paper (see 5.3) on the plate (see 5.1.2). Lower the pendulum with the milling segment to the surface of the emery paper in the device and carry out sufficient double travel movements without the c

38、lamping plate rotating, such that the whole surface of the leather sole is roughened. The leather sole shall be replaced when it is worn down to 2 mm. 9 Control test for the emery paper Test for control purposes approximately 1 % of each delivery of the pieces of emery paper. Condition the pieces to

39、 equilibrium in the standard climate (see Clause 7). Report the last mass reading. Fix the device with emery paper (see 5.3) on the clamping plate (see 5.1.2). Fix another piece to the abrading segment of the pendulum and lower the pendulum to the surface of the piece of emery paper in the device (g

40、rain side to grain side). Carry out 10 linear double travel movements, without the clamping plate rotating and without ventilation and suction. After removing both pieces from the apparatus remove the loosened grains from the pieces. To achieve this allow the pieces of paper to fall on one length ed

41、ge from a height of approximately 100 mm. The total mass loss of the two pieces shall be (0,7 0,1) g. 10 Procedure 10.1 Determination of density For heterogeneous floor coverings separate the wear layer from the sample by abrading the underside until only the wear layer is left. Determine the densit

42、y of the wear layer according to EN 436, method A or B. For homogeneous floor coverings, if the sample is smooth on top and on the underside, the density may be determined using a rectangular specimen. Weigh the specimen to an accuracy of 0,1 mg and measure the length and width to 0,1 mm and the thi

43、ckness to 0,01 mm accuracy. Otherwise follow EN 436, method A or B. NOTE If the density cannot be determined, the loss of volume cannot be reported. 10.2 Abrasion test 10.2.1 Weigh the specimens to an accuracy of 0,1 mg after conditioning to determine the initial mass m 1 . 10.2.2 Carry out the wear

44、 tests in cycles, each consisting of the following stages. 10.2.2.1 Indentation stress of the specimen surface with the steel-tack plate prior to the first cycle (see 5.6). Centre the plate on the specimen and exert a force of (4 000 100) N for 60 s. EN 660-1:1999 BSI 23 July 2003 9 10.2.2.2 Wear st

45、ress with emery paper fixed on the abrading segment of the pendulum. Lower the pendulum to the surface of the specimen and carry out three double travel movements of the roller table whilst the clamping plate with specimen rotates, without ventilation or suction. Leave the detached grains of abrasiv

46、e on the specimen. 10.2.2.3 Stress with the leather sole fixed on the milling segment. With the grains of abrasive on the specimen, lower the pendulum to the surface of the specimen and carry out 4 50 double travel movements of the roller table whilst the clamping plate with specimen rotates without

47、 ventilation or suction. After each 50 movements raise the pendulum from the specimen for 2 min to allow the specimen and the leather sole to cool down without cleaning the specimen. 10.2.2.4 Cleaning of the specimen. Clean the specimen at the end of the 200 double travel movements with a soft-hair

48、hand brush and/or a vacuum cleaner. 10.2.2.5 Roughening of the leather. Roughen the leather according to Clause 8, carrying out only five double travel movements of the roller table without rotation of the clamping plate, with simultaneous ventilation and suction. Clean the leather (see 10.2.2.4). 1

49、0.2.3 Repeat the cycle on the second and third specimens. Carry out the cycle 20 times with each specimen. 10.2.4 At the end of the 20 wear cycles clean the surface of the specimens with a hard, dry brush and then remove the fine dust with the soft-hair brush. 10.2.5 Recondition the specimens in the standard climate to equilibrium (see Clause 7) and reweigh to determine the final mass m 2 . 11 Calculation and expression of
