AWPA Standards
As the principal
consensus-based standards writing organization for the wood
treating industry in the United States, AWPA also has significant
influence internationally. AWPA Standards are written to safely and
effectively extend the service life of our most valuable renewable
resource - wood. The Standards are recognized and used by customers
worldwide, who purchase and use treated wood for applications in the
building products, electrical, marine, railroad transportation, and
road construction industries.
AWPA Standards are written, edited and revised as its Technical Committee members work on new developments within the field of wood
preservation. The Association conducts annual meetings for the
general membership (April/May) and the Technical Committee members
(in conjunction with the annual meeting and in September). Results of the Annual Meeting are published each year
in the AWPA Proceedings, and the Book of Standards is updated
annually as a result of Technical Committee activities. Specifying AWPA Standards
When
purchasing treated wood products under these Standards, purchase
orders, to be complete, should state the specific Standard number or
numbers that are pertinent and also cover the following: species of
wood, quality of wood products before treatment, requirements for
manufacturing, surface preparation, limitations if any, special
conditioning, preservative and methods of retention determination.
Only those species and preservatives are listed in a commodity
specification and standard that have previously been found suitable
for use in this particular application, or for which test
information has been submitted to warrant their inclusion. When
choosing a treated wood product to serve in a specific situation,
the purchaser can obtain appropriate recommendations for the
preservative-commodity combination from either the treating company
or from qualified authorities if the use conditions are carefully
described. |
