It does not apply to leather and textile surfaces. It does not a
23、pply to the surfaces covered by EN 14434. The test is intended to be carried out on a part of the finished furniture, but can be carried out on test panels of the same material, finished in an identical manner to the finished product, and of a size sufficient to meet the requirements of the test. Th
24、e test shall be carried out on unused surfaces. 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 latest edition of the referenced document (including any
25、 amendments) applies. EN ISO 6506-1, Metallic materials Brinell hardness test Part 1: Test method (ISO 6506-1:2005) ISO 9352, Plastics Determination of resistance to wear by abrasive wheels DIN EN 15185:2011-07 EN 15185:2011 (E) 4 3 Terms and definitions For the purposes of this document, the follow
26、ing terms and definitions apply. 3.1 test surface part of the test panel 3.2 test panel panel including the test surface NOTE It may be cut from a finished item of furniture or it may be a separate panel produced in the same manner as the finished item of furniture. 3.3 test area part of the test su
27、rface under the wheels covered by the abrasion paper strips (5.3) 3.4 colour rendering index (CRI or Ra) unitless number that specifies how well the colour of an object appears under illumination by a light source compared to a reference light source 4 Principle The test simulates the ability of the
28、 furniture surface under test, to resist abrasive wear-through. Abrasion is achieved by rotating a specimen in contact with a pair of loaded cylindrical wheels covered with abrasive paper. The wheels are positioned so that their cylindrical faces are equidistant from the specimens axis of rotation b
29、ut not tangential to it. As they are turned by the rotating specimen they abrade an annular track on the specimens surface. The number of revolutions of the specimen required to cause one defined degree of abrasion, is used as measurement of resistance to surface wear. 5 Apparatus and materials 5.1

40、Conditioning Conditioning of test surface shall begin at least one week before testing and shall be carried out in air at a temperature of (23 2) C and relative humidity of (50 5) %. The conditioning time shall be stated in the test report. Condition the abrasion paper strips at least for one week i
41、n the conditioning atmosphere of (23 2) C and (50 5) % R.H., before testing, see 5.6. 6.2 Test surface Three test surfaces shall be prepared. The test surface shall be taken at least 5 mm from the edge of the test panel. Each test surface shall be a piece of test panel, shaped to fit the type of cla
42、mping device used. It shall usually be a square of 100 mm x 100 mm, and including an appropriated hole drilled in the centre to place the test surface in the axis of the apparatus. The test surface shall be carefully wiped with a cleaning cloth (5.1) before the test. The test surface shall be substa
43、ntially flat. 6.3 Preparation of test surfaces and abrasive paper Using a suitable marker pen, mark the surface of each test surface with two lines at right angles, diagonals, so that the surface area is divided into four quadrants, according to Figure 1. Figure 1 Test surface area divided into four
44、 quadrants 7 Test procedure 7.1 Preparation of abrasive wheels Bond a strip of conditioned unused abrasive paper to each of the rubber covered wheels. Ensure that the cylindrical surface is completely covered, but without any overlapping of the abrasive paper. 7.2 Calibration of abrasive paper Carry
45、 out this calibration three times for each box. DIN EN 15185:2011-07 EN 15185:2011 (E) 7 Prepare two abrasive wheels, in the correct hardness range (5.4), with conditioned unused strips of abrasive paper. Clamp a zinc plate in the specimen holder, start the vacuum device, set the revolution-counter
46、to zero, lower the wheels, ensuring that the arms are horizontal and the load on the zinc plate is (5,4 0,2) N, and abrade the zinc plate for 500 revolutions. Wipe the zinc plate clean and weigh to the nearest 1 mg. Replace the abrasive paper on the wheels with preconditioned unused strips from the
47、same batch, clamp the same zinc plate in the specimen holder, lower the abrasive wheels and operate the suction device. Abrade the zinc plate for an additional 500 revolutions, then wipe it clean and reweigh it to the nearest 1 mg. Any box containing abrasive paper which causes a loss in mass of the
48、 zinc plate which is outside (120 20) mg, for any pair of calibrate strips, shall not be used for testing. The result (mean value of the 3 calibrations / 120) shall be named “correction factor“ and shall be included in the test report. 7.3 Abrasion of test area Perform the test immediately after rem
49、oval of the test surface and calibrated abrasive paper from the conditioning atmosphere. Prepare two wheels, in the correct hardness range, with preconditioned unused abrasive paper from the same box previously approved by calibration. Fit the wheels to the machine and set the revolution counter to zero. Clamp the test surface in the holder, ensuring that it is placed horizontally. Lower the abrasive wheels on to the specimen,
