Introducti
27、on This document is one of a series of standards specifying requirements and test methods for wood flooring and wood panelling and cladding. The measurements should be carried out as specified in this standard or with any other equipment or principles giving at least the same accuracy. DIN EN 13647:
28、2011-08 EN 13647:2011 (E) 5 1 Scope This European Standard specifies methods of measuring the geometrical characteristics of wood flooring and wood panelling and cladding elements. This European Standard does not specify sampling, which is intended to be found in the product standards or test method
29、s and it does not apply to elements which are installed. 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 (incl
30、uding any amendments) applies. EN 13756:2002, Wood flooring Terminology 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 13756:2002 apply. 4 Principles 4.1 General The measurements shall be carried out only if relevant, taking the product standards int
31、o account. 4.2 Dimensions The dimensions are determined by measuring any characteristic defined in the product standard and with appropriate tools. 4.3 Angles Determine square angles by measuring the distance (maximum value) between an edge of the element and the side of a square whose other side is
32、 in line with an adjacent edge of the element. Determine other angles by the use of a protractor. 4.4 Warp 4.4.1 Cup Determine cup by measuring, at the middle of the width of the element, the distance separating the face of the element from the straight reference line joining the top arises of the e
33、dges of the element, see Figures 1 and 2.

34、 7 4.4.2 Bow Determine bow by measuring, at the middle of the length of the element, the distance separating the face of the element from the straight reference line joining the end top arises of the element, see Figures 3 and 4. NOTE If the maximum bow is not in the middle of the length, the measur
35、ement can be carried out at the appropriate place and this should be mentioned in the report.

37、t reference line joining the two arises of that edge, see Figure 5. NOTE The measurement is usually carried out on the edge bearing the groove.

38、pping Determine lipping by measuring the difference in the levels of the face of two adjacent elements when they are assembled together, see Figure 6. DIN EN 13647:2011-08 EN 13647:2011 (E) 10 Key 1 lipping Figure 6 Example of lipping 5 Equipment 5.1 General The equipment specified in this standard
39、is given as an indication. Any other equipment providing the same results with at least the same accuracy may be used. 5.2 Equipment to measure the dimensions 5.2.1 Calliper It shall have an accuracy of 0,05 mm. If used to measure the characteristics of tongue and groove profiles, it shall have a bu

It shall also have a useful measuring length corresponding to the width of the elements to be measured. 5.2.2 Micrometer It shall have a limit deviation of 0,05 mm and two parallel flat circular feelers having a diameter of (10 1) mm. 5.2.3 Graduated rule It shall be used when the
41、dimensions to be measured are out of the callipers range. It shall have a limit deviation of 0,5 mm up to a length of 2 m, and 1 mm for longer lengths. 5.3 Equipment to measure angle values 5.3.1 General The design of the equipment shall be such as to allow the measurement as close as possible to th
42、e face of the element and preferably on the groove side if the element is tongued and grooved. DIN EN 13647:2011-08 EN 13647:2011 (E) 11 5.3.2 Equipment for square cut elements A reference square with its longer arm consistent with the length of the elements to be checked and shall not be less than
43、210 mm, Each arm shall have a fixed feeler at about 10 mm from the corner, The longer arm shall have a second feeler, adjustable between 200 mm and 300 mm from the fixed feeler, The shorter arm shall have a gauge, readable to the nearest 0,01 mm, adjustable to the width of the element to be controll
44、ed. NOTE an example of such a square is shown in Figure A.1 A calibration square to set the gauge to 0. 5.3.3 Equipment for mitre-cut elements Protractor fitted with a vernier with a limit a limit deviation of 1 min of angle. 5.4 Equipment to measure warp 5.4.1 Equipment to measure cup A gauge with
45、an accuracy of 0,01 mm with a rounded tip with a radius of (5 0,2) mm, installed centrally in relation to the three rounded supports with a radius not less than 5 mm. This shall be adjustable along a T assembly of bars according to the gauge length to be achieved. The tip of the gauge in contact wit
46、h the face of the element shall apply a force of less than 5 N 1) Figure B.1 gives an example of such a device and Figure B.2 shows gauging of the device. 5.4.2 Calibration plate A reference plate of suitable material to calibrate to zero the gauge fitted on the apparatus defined in 5.4.1. 5.4.3 Equ
