This Standard sets out the method for determining the slope of grain in timber articles that are either regular or irregular in plan or section by reference to checks appearing on the surface. This Standard is one of a number dealing with determination of slope of grain.This method for determination of slope of grain is suitable for use on timber articles with dressed surfaces which exhibit checks.NOTE: Where predictable strength of timber is the primary consideration, sloping grain can be an important characteristic. It is often difficult to detect by visual examination of the surface. The importance of the characteristic will be appreciated where it is realized that sloping grain means that a beam with sloping grain has a strength that may be significantly less than the strength of the wood fibre in the beam, e.g. there is a reduction in the strength of beams, from the fibre strength, of approximately 20 percent for a slope of 1 in 16, 30 percent for a slope of 1 in 12 and 50 percent for a slope of 1 in 8. Grading processes identify this reduction in performance.It is stressed that this test method determines only whether or not a piece of timber has slope of grain and its magnitude. It does not set down any criteria for grade specifications.
