28、d without “tongue and groove” which have been machined on the face and two edges. NOTE The back is either machined or hit and/or missed, depending on the product. For special purposes (for instance, acoustic) the edges may have fastening slots. The ends of the boards may be end matched 3.2 end match

30、bols and abbreviations Symbols and abbreviations used in this European Standard are given in Figure 1 and in Table 3 and Table 4. 5 Requirements 5.1 General The softwood species shall be selected with regard to the appearance expected, the suitability for the intended purpose and the general charact

31、eristics of the species itself. All requirements apply at the time of production unless the manufacturer states otherwise. 5.2 Appearance and finishing 5.2.1 General Grading applies to the face only, unless otherwise specified. Machining requirements are covered in 5.4.4 and apply to all grades of a

32、ll species. Natural variation within a single species is generally accepted as a common feature of wood and is not considered for classification of appearance, with the exception of free grade. Measuring features shall be in accordance with EN 1310. Concerning knots the general method in EN 1310:199

33、7, 4.1.1, applies. The boards may be finished with surface coating. The grading shall be done before coating.
