Test Methods and Standards
  1. To apply for wood and/or bamboo identification, an applicant can go to TFRI forest utilization service network, and download the application form and complete the relevant information requested. The sample in question should be cut to appropriate sizes: the thickness, width, and length should be greater than 2cm, 10 cm, and 15 cm, respectively. Bamboo culmss or bamboo products must be no less than 15 cm in length.Ship the trimmed sample to TFRI along with the application form.

  2. Because woods from different genera or species have various colors, odors, grains, and cell structure characteristics, the features of a wood specimen can be identified by smelling it, or examining its cross section using naked eyes, a magnifying len, or a microscope. Its genus name or species name can then be determined by following a dichotomous identification table.

  3. Prior to beginning the identification process, the wood anatomist will first trim the sample and examine its color, grain, texture, cross section, and other indicators. Meanwhile, a small-size test sample of appropriate size will be prepared, and sharp razor blades will be used to produce smooth cross-sectional surfaces; the cell structure of the sample will then be further examined under a magnifying len and a microscope.

  4. If the species cannot be identified under a stereo microscope, then a standard three-sectional sample of 1 cubic centimeter will be prepared, and thin sections of the sample will be prepared using a sliding microtome. After staining, a temporary slide containing the 3 sections will be examined under a light microscope, and the features of the wood will be recorded and photos will be taken to establish a file.

  5. Upon completion of the identification procedures, a detailed report including the scientific name, commercial name, and family name of the specimen in question will be prepared and mailed to the applicant.
