    17、1:2016 (E) 4 1 Scope This Technical Specification specifies a method for the assessment of the surface resistance to microscratching and relates to rigid surfaces of all finished products regardless of materials. Method A is suitable for all types of surface coatings and coverings except for lacquer

    18、s with pearly or metallic effects. Method B is suitable for all types of surface. It does not apply to finishes on leather and fabrics. The test is intended to be carried out on a part of finished furniture, but can be carried out on test panels of the same material, finished in an identical manner

    19、to the finished product, and of a size sufficient to meet the requirements of the test. It is essential that the test is carried out on unused surfaces. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its appl

    20、ication. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

    37、he tester shall be carried out in accordance with the instructions of the apparatus manufacturer. For the described test, the outer position C shall be used for both axes to create the larger Lissajous figure as explained in EN ISO 12947-1 or the manufacture guidebook. The checking of the Lissajous

    38、figure shall be done according to Annex A. 7 Preparation and conditioning 7.1 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 i

    42、16611:2016 (E) 8 8.2 Testing 8.2.1 Procedure A 8.2.1.1 Calibration of ultra fine scrub material Procedure A is also valid for checking of every new batch of ultra fine scrub materials (5.6). In this case, 3 test surfaces shall be taken from reference high gloss HPL (5.9). The batch of ultra fine scr

    43、ub materials shall be used for testing if the mean value of gloss change, determined with 20 reflectometer geometry, is in the range from 15 % to 30 % according to EN ISO 2813. 8.2.1.2 Microscratching of test area Immediately after conditioning, the test shall be carried out in a test temperature of

    44、 (23 2) C at 3 test surfaces. Before the test, 4 gloss measurements on each test surface using the reflectometer (5.4) with a geometry of 60 and the positioning device (5.5) shall be carried out. If there is a decor or preferential structure direction on the test surface the measurement shall be don

    45、e parallel to this direction. Calculate the mean value for each test surface. If the mean value is higher than 70 (high gloss surface) additional four measurements with the 20 geometry shall be carried out. Fix the test surface on the table of the Martindale tester using the adhesive tape (5.7). The

    46、 ultra fine scrub material shall be fixed with the adhesive tape on the guide plate of holder. Select 80 rubs on the counter of the Martindale device and start the test. After finishing remove the test surface from the table and clean it with the cleaning cloth (5.8). Remove also the used scrub mate

    47、rial. Measure the gloss again with the chosen geometry according to the above described procedure. Calculate for each test surface the gloss change R according to the following formula: = 100 RI RF R RI% (1) where RI is the mean value at initial state; RF is the value after finishing the test. Calcu

    48、late the mean value of the gloss change of the 3 test surfaces and round it on the next integral number. 8.2.2 Procedure B 8.2.2.1 Calibration of very fine scrub material Procedure B is also valid for checking of every new batch of very fine scrub materials (5.6). In this case, 3 test surfaces shall

    49、 be taken from reference high gloss HPL (5.9). The batch of very fine scrub materials shall be used for testing if the mean value of scratch pictures is 3 or 4 (Annex B). 8.2.2.2 Microscratching of test area Immediately after conditioning, the test shall be carried out in a test temperature of (23 2) C at 3 test surfaces. PD CEN/TS 16611:2016 CEN/TS 16611:2016 (E) 9 Fix the test surface on the table of the Martindale tester using the adhesive tape (5.7). The very fine scrub material shall be fixed on the g
