Affidavit:

All testing and associated procedures were conducted at Dirigo Laboratories beginning 12/29/2014 and ending on 1/29/2015. Dirigo Laboratories is located at 11785 SE Highway 212 – Suite 305, Clackamas, OR 97015-9050. All EPA protocols from Methods 1, 2, 3, 4, 5, 28 WHH and ASTM 2618-13 were followed in the testing, sampling, analysis, and calibrations for these tests and all results are based on these methods. Particulate sampling was performed per EPA Method 5G sampling option 3 and ASTM E2515-11 Standard Test Method for Determination of Particulate Matter Emissions Collected in a Dilution Tunnel. Efficiency was calculated using EPA Method 28WHH and checked using CAN/CSA-B415.1-10 Performance Testing of Solid-Fuel Burning Heating Appliances.

The following people were associated with the testing, analysis and report writing associated with this project.

Analytical Methods Description: All sample recovery and analysis procedures followed EPA Method 5g3 procedures. At the end of each test run, filters were removed from their housings, dessicated for 24 hours, and then weighed to a constant weight per Method 5 section 11.0.

Quality Control and Assurance Procedures and Results:

Calibration procedures and results were conducted per ASTM 2515-11, EPA Method 1 through 5, 5g and Method 28WHH. Calibration certificates and results can be found in Appendix E.

Test method quality control procedures (leak checks, volume meter checks, stratification checks, proportionality results) followed the procedures outlined in Method 5.
