28、2012 (E) This document (EN ISO 24342:2012/A1:2012) has been prepared by Technical Committee ISO/TC 219 “Floor coverings” in collaboration with Technical Committee CEN/TC 134 “Resilient, textile and laminate floor 1 Scope This International Standard describes methods for determining side lengths, str

29、aightness of edges and squareness of resilient or textile floor tiles. The side lengths, straightness and squareness of resilient or textile floor tiles are important considerations because installed flooring will have an objectionable appearance if these performance criteria are not followed. This

30、may cause the installed tiles to line up unevenly, producing unsightly seams and corners that do not match. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 squareness measurement of the amount each corner of the tile deviates from 90 See Figu

31、re 1. Figure 1 Definition of squareness 2.2 straightness property of an edge to be straight, unbent See Figure 2. 4 DIN EN ISO 24342:2013-04 EN ISO 24342:2012 + A1:2012 (E) Figure 2 Definition of straightness 2.3 tile type of resilient or textile flooring of predetermined shape intended to be used i

32、n a modular mode NOTE Tiles are usually square, but can also be rectangular, e.g. “plank”, “panel”. 3 Principle The surface dimensions of a tile are measured by a contact method at defined positions in each direction. To assess the squareness, each corner of a right-angled tile is fitted into the di

33、hedral angle of a precision square and the maximum gap between the arm of the square and the ends of the tile is measured. The maximum opening between the arm and the edge is measured at defined points along the edge to assess the straightness. 4 Apparatus 4.1 Reference plate (calibration plate), ma

34、de to the target dimensions of the manufactured tile. The length and width dimensions shall be within 0,02 mm of the specified dimensions of the resilient or textile tiles. The reference plate shall contain at least two sides that are perpendicular to 0,000 05 rad (0,003) to one or another and are u

35、sed to set squareness gauge to zero (see Figure 3). 5 DIN EN ISO 24342:2013-04 EN ISO 24342:2012 + A1:2012 (E) Dimensions in millimetres aTile target dimension 0,02 mm. b1,570 80 rad 0,000 05 rad.

36、10 mm less than those of the tile, for the thickness gauge method. The mass per unit area of the plate shall be approximately 20 kg/m2. 4.3 Flat bedplate apparatus, for measuring squareness and straightness of floor tiles. This apparatus shall be an “L” shaped steel device having an angle of 1,570 8

37、0 rad (90) with a tolerance of 0,000 05 rad (0,003), as shown in Figures 4 and 5 with the length of both reference strips larger than the largest dimension of the tile. For measuring side length, a dial gauge is also placed on the flat bedplate according to Figure 6. 6 DIN EN ISO 24342:2013-04 EN IS

40、easily inserted at any point between the “L” shaped steel device and the edge of the tile. 4.5 Movable dial gauges apparatus, containing two fixed index strips according to Figure 7. A horizontal index strip shall be mounted parallel to and just inside the lower edge of the bedplate. It shall be 38

41、mm 3 mm greater in length and a minimum of twice the thickness of the largest resilient or textile tile to be tested. A second index strip shall be mounted 1,570 80 0,000 05 rad (90 0,003) to the horizontal index strip. The lower end of this index strip shall be 3,1 mm 0,25 mm above the right end of

42、 the horizontal index strip and is used to locate one corner of the sample tile. The length of the second index strip shall be maximum 10 mm. The four dial gauges are mounted allowing for measurement of various tiles side lengths while remaining within 10 % of the corner of the tile edge (for the tw

43、o corner gauges and one squareness gauge) or within the central 10 % of the tile edge (for the centre gauge only). Dial gauges may report measurements using electrical or mechanical means, but they shall be graduated to read 0,02 mm and have a stem travel greater than 6 mm. The contact foot of the d

44、ial gauge stem shall be flat, 12,7 mm to 19,1 mm in diameter and exert a total force of not more than 1,0 N. Dial gauges shall be securely positioned so that when the reference plate is in place, the contact foot is extended approximately 50 % of its full travel. 8 DIN EN ISO 24342:2013-04 EN ISO 24
