Active AWPA Proposed Evaluation Methods (PEM)
Proposed Evaluation Methods are not Standards. They are a means of publishing methods for evaluating the performance of a preserved and/or protected wood product. This enables laboratories to "test drive" these methods and provide feedback to AWPA Technical Committee P-6 to improve them, based on real-world experience. Usually, PEMs found useful are ultimately proposed to Technical Committee P-6 to be adopted as "E" Standards. For more information on PEMs, please consult Section 6 of the AWPA Technical Committee Regulations. To submit a proposal to revise or renew a PEM, click here to download the PEM Proposal Form.
