Scope

1.1 This test method covers a non-chemical, biological procedure for assaying wood for approximate preservative content (Note 1). It requires minimal equipment and technical proficiency. No costly equipment is needed other than a small autoclave for preparing fungal media. It does not require composite samples, such as called for in Specification D1760 to ascertain preservation retentions, therefore it is used to assess retention at individual locations.

Note 1--With appropriate, simple adaptation, the method can be used with other products besides wood, such as fungicidal paints and glues. The assaying is done wherever it is convenient, since aseptic precautions are not required except for maintaining a pure stock culture of the assay fungus.

1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, 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.
