General 1. In general, a parcel of timber in any grade shall contain a range in quality, from the most defective piece permitted in that grade, to a piece which just fails to comply with the requirements of the next grade higher. 2. When timber is visually graded, a reasonable difference of opinion between graders is recognized. A maximum allowable inclusion of “Off Grade” or below grade of five percent (5%) in any parcel must be regarded as an acceptable allowable variation. 3. It is advisable for all customers to be familiar with both the requirements of the NZ Building Code, those of the local approving authority and the terms and conditions their building consent is granted in regard to profiles, grades and fixing.
4. It should be expected as a natural consequence of drying that knots (when present) may include seasoning checks or splits. Macrocarpa... Taking over the Building Trade in New Zealand
