American Wood Protection Association
Founded in 1904, the American Wood Protection Association (AWPA), formerly American Wood-Preservers' Association, is a non-profit organization which is responsible for promulgating voluntary wood preservation standards. AWPA Standards are developed by its technical committees in an open, consensus-based process that involves individuals from all facets of wood preservation: Producers of preservatives and preservative components; producers of treated and untreated wood products; end users of treated wood; engineers, architects and building code officials; government entities, academia, and other groups with a general interest in wood preservation. AWPA's Standards are universally specified for wood preservation in the USA, and are recognized worldwide.
AWPA standards help ensure that treated wood products perform satisfactorily for their intended use. They are recognized and used by most, if not all, specifiers of treated wood including electrical utility, marine, road and building construction as well as by local, state and federal governments. "AWPA", "American Wood Protection Association", identifiers of AWPA Standards (e.g., U1, T1, M4, etc.), and Use Category designations (e.g., UC1, UC3B, UC4A, etc.) are AWPA trademarks and the intellectual property of AWPA and its Technical Committees.
Wood preservative systems produced under the AWPA standards system for the residential market are required to be inspected under the stringent American Lumber Standards Committee (ALSC) third party inspection system in order to assure compliance with AWPA standards.
While many wood preservative systems are produced under the AWPA standards system, there are wood preservative products in the market that have not earned AWPA standard status and are not subject to the ALSC inspection system. Compliance with AWPA and ASLC will be noted by the AWPA logo on the product end tags.

Famous quotes containing the words american, wood, protection and/or association:
“For most Northerners, Texas is the home of real men. The cowboys, the rednecks, the outspoken self-made right-wing millionaires strike us as either the best or worst examples of American manliness.... The ideal is not an illusion nor is it contemptible, no matter what damage it may have done. Many people who scorn it in conversation want to submit to it in bed. Those who believe machismo reeks of violence alone choose to forget it once stood for honor as well.”
—Edmund White (b. 1940)
“This is the poem of the air,
Slowly in silent syllables recorded;
This is the secret of despair,
Long in its cloudy bosom hoarded,
Now whispered and revealed
To wood and field.”
—Henry Wadsworth Longfellow (1809–1882)
“Take away from the courts, if it could be taken away, the power to issue injunctions in labor disputes, and it would create a privileged class among the laborers and save the lawless among their number from a most needful remedy available to all men for the protection of their business interests against unlawful invasion.... The secondary boycott is an instrument of tyranny, and ought not to be made legitimate.”
—William Howard Taft (1857–1930)
“... a Christian has neither more nor less rights in our association than an atheist. When our platform becomes too narrow for people of all creeds and of no creeds, I myself cannot stand upon it.”
—Susan B. Anthony (1820–1906)
