ASTM D3345-74(1999)

Standard Test Method for Laboratory Evaluation of Wood and Other Cellulosic Materials for Resistance to Termites

SCOPE
1.1 This test method covers the laboratory evaluation of treated or untreated cellulosic material for its resistance to subterranean termites. This test should be considered as a screening test for treated material and further evaluation by field methods is required.  
1.2 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautions, see 6.1.5.
