9、EN 385:2007-11 (withdrawn 2013-09) as follows: a) the standard has been revised as a product standard for structural finger jointed solid timber taking into account the requirements of Regulation (EU) No 305/2011; b) the former Clause 7 “Quality control” has been replaced by a new Clause 6 “Assessme

10、nt and Verification of Constancy of Performance (AVCP)”; c) specifications for the drawing up of a declaration of performance have been added; d) requirements for marking and labelling have been included; e) a list of the applicable species has been added; f) requirements for phenolic and aminoplast

11、ic adhesives, moisture curing one-component polyurethane adhesives (PUR) and emulsion polymer isocyanate adhesives (EPI) have been added; g) requirements for application devices for the separate application of resin and hardener have been added; h) provisions for contact free adhesive application ha

12、ve been added; i) provisions for resistance to fire and accuracy of size have been added; j) for durability against biological attack, reference is made to EN 15228; k) provisions for formaldehyde emission and release/content of other dangerous substances have been added.

39、 sets out provisions regarding the performance characteristics for structural finger jointed timber with rectangular cross section for use in buildings and bridges. The use of structural finger jointed timber may be limited to certain service classes in some member states. It also lays down minimum

40、production provisions and procedures for Assessment and Verification of Constancy of Performance for structural finger jointed timber. This European Standard is applicable to structural finger jointed timber made of coniferous timber species listed in this standard or poplar. Although it may be poss

41、ible to produce structural finger jointed timber made from specific broadleaf species based on some provisions of this European Standard, this standard is not applicable to these products. This European Standard is only applicable to finger joints between timber sections of the same species. This Eu

42、ropean Standard does not cover impressed (die-formed) finger joints. This European Standard covers structural finger jointed timber untreated or treated against biological attack. Structural finger jointed timber treated with fire retardants is not covered. 2 Normative references The following docum
