The National Council of Air and Stream Improvement (NCASI) has maintained itself as an independent non-profit research organization founded by the wood products industry in 1943.  In the absence of adequate air and water test methods relevant to the analytes and source types found at wood products facilities, NCASI began developing and publishing air and water test methods in the 1990s.

Enthalpy has been proactive in understanding, executing and adding these methods to our NELAP scope of accreditations as they become available.  We have developed a thorough understanding of the in-lab and in-field performance measures for each method which help validate a test program.

The NCASI Methods primarily focus on the sampling and analysis of alcohols (methanol, phenol) and aldehydes (formaldehyde, acetaldehyde, acrolein, propionaldehyde).  The suitability of NCASI test methods goes beyond wood products facilities, and they are often used for engineering as well as compliance testing.

NCASI Methods:
• 8A, 94.02, 94.03, 98.01, 99.02, 105.01
