Abstract

The grading of timber for quality is conducted by visual means. The main purpose of grading of timber is to enable the raw material which is inherently of widely varying quality to be classified into groups suitable for the different purposes for which timber is used. Classification according to quality which cannot be exact, is highly subjective. The British Standard BS4047:1966 (1980) gives detailed rules for the grading of hardwood grown in the United Kingdom by means of the cutting system and the defect system. This paper outlines the use of computer in the defect system as an aid to reduce the subjective nature of the system and the transformation of qualitative description to the quantitative argument.
