18、rd is one of two standards for the classification of solid wood panels by surface appearance, the other is: EN 13017-2, Solid wood panels Classification by surface appearance Part 2: Hardwood. 1 Scope This European Standard specifies general requirements and appearance classes for both single-layer

19、and multi-layer solid wood panels, the latter with a minimum thickness of the outer layers of 3,5 mm, manufactured from softwood species (e.g. spruce, pine, larch). 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These no

25、to timber which are given in those parts of EN 844 listed in Clause 2.Page 4 EN 13017-1:2000 BSI 01-2001 4 General requirements 4.1 General requirements for multi-layer solid wood panels All types of panels shall have a symmetrical construction throughout their thickness. The outer layers of panels

26、for structural use (see Grade S) shall have a minimum thickness of 5 mm. All pieces of the outer layers (face and back) shall normally be made of the same wood species; exceptions are given in Table 1. The surfaces of the panel shall be finished according to their intended use (e.g. sanded, planed,

27、coated). Inner layers shall not have open joints (whether they are glued or not). Discolouration, slight rot and single small wormholes are permitted. 4.2 General requirements for single-layer solid wood panels All joints shall be glued properly; open joints are not permitted. The minimum length for

28、 pieces for Type SC is given in Table 2. Panels with pieces of timber cut in length may have pieces finger jointed, butt jointed or have any other type of end joint. 5 Appearance classes 5.1 General Classification for appearance classes shall be in accordance with the requirements given in Table 1.

29、The measurements of features shall be made according to EN 1310. For knots the general method according to EN 1310:1997, 4.1.1 shall be used. 5.2 Appearance classes of multi-layer solid wood panels Assessment of appearance classes shall be made for both the face and the back of the panel. In marking

30、 and specification, the symbols of the classes of both face and back shall be given separated by a slash as face class/back class (Examples: A/B, B/B, B/C, A/C, S/S). Class S is intended for structural use (e.g. formwork and construction panels). The combination of Class S with another class within

31、the same panel is unusual.Page 5 EN 13017-1:2000 BSI 01-2001 Table 1 Appearance classes for surfaces of multi-layer solid wood panels Appearance class Features 0ABCS Glueing No open glue lines Open joints 100 mm/1 m glue line permitted Mixture of species Not permitted Not permitted; with spruce, how
