Compression Wood Identification in Pulpwood, Test Method T 267 cm-15
This method is concerned with the detection of the compression wood that can be recognized by unaided vision or by means of a simple viewing device (1). Normally this is sufficient for operating purposes. Microscopic and chemical tests may be required in special cases.
Severe and intermediate forms of compression wood are easily recognized, once the observer becomes familiar with their general characteristics. The borderline form requires some practice to distinguish it from normal wood. A viewing box is useful for training an observer and as an aid in deciding doubtful cases.
