Reemplazada por: DIN 4074-1:2012-06

This standard is applies to coniferous sawn timber for components, which must be measured according to their strength. It specifies grading characteristics and classes as a precondition for the specification and application of calculation values for the verification of limiting strength and usability according to DIN 1052 or Din 1074. Grading can be done by two methods: - visually with grading classes (according to clause 6); - visually with support of technical appliances (according to clause 7). For special use of timber special standards are applicable regarding the strength grading : DIN 68326 and DIN EN 131-2 for wooden ladders, DIN 15147 for flat pallets. In the presented Amendment footnote a in Table 2 was deleted in order to create the necessary preconditions to enable the European application of the current DIN 4074-1:2008-12 and to realize its inclusion in EN 1912. This was not possible so far as a proof was missing to which European strength classes the classes S 7 and S 10, being altered by footnote a, can be assigned to.
