Notes:
l Testing conducted by Battelle of Columbus, OH
ll Warnock Hershey Certified for ASTM D6662-01 by Intertek Testing Services NA Ltd. of Coquitlam,BC.
For further information on our ASTM standards please contact your Plastic Lumber Yard representative.
For further information on Intertek Testing Services NA Ltd. and the Warnock Hershey certification, please contact ITS at: www.ETLSemko.com
For Further information and their processes please contact ASTM at: www.astm.org
Chemical Resistance
Since high density polyethylene has a high resistance to most acids and chemicals,
Plastic Lumber is not affected by exposure to most substances.
Ultraviolet Weathering
An ultraviolet stabilizer is incorporated at the time of manufacture. It protects the plastic from ultraviolet light degradation and ensures that the outside of the product will not degrade in exterior applications.
