21、 terms and definitions given in EN 844-1:1995, EN 844-2:1997 and EN 844-5:1997 apply. 4 Dimensional classification Dimensional classification shall be made, irrespective of length, into classes according to the mid diameter under bark or over bark. The under bark classification is described by a D l
22、etter. The over bark classification is described by an R letter. The D or R letter shall specify the type of class. If round timber is measured over bark, this should be agreed by contract including the bark allowance. Possibilities for bark allowance are e.g.: agreed reduction from the diameter (me
23、dium or top diameter); reduction in percent (%) of the circular area; use of regional common bark allowance tables. The classification shall be made using either one or the other following classes: DIN EN 1315:2010-04 EN 1315:2010 (E) 5 Table 1 Dimensional classification of round timber Class under
