ASTM D143 Timber Clear Specimen Test Equipment

ASTM D143 contains the standard test methods for testing small clear timber specimens. The data from ASTM D143 test methods can be used to compare the mechanical properties of various species, establish allowable stresses, and determine the influence of density, locality of growth, height, and treatment of chemicals on the mechanical properties.


This standard contains test methods for determining the various strength and elastic properties of wood through 11 different mechanical tests:

  • static bending
  • impact bending
  • compression parallel to grain
  • compression perpendicular to grain
  • toughness
  • hardness
  • shear parallel to grain
  • cleavage
  • tension parallel to grain
  • tension perpendicular to grain
  • nail withdrawl
