Test Results
Testing was conducted in accordance with ASTM E84-91a and CAN4-S102-M88
"Standard Method of Test for Surface Burning Characteristics of Building Materials
and Assemblies" by Underwriters Laboratories of Canada. Following is a summary
of the results of those tests
| Material | 1FSR | 2SDC |
| Douglas Fir Lumber, coated by SAFECOAT LATEX ® with a single coat at a rate of 3. 7 m2 per liter. | 5 | 5 |
| S-P-F Plywood Coated by SAFECOAT LATEX ® with a single coat at a rate of 3.7m2 per liter and a single coat of Safecoat 725 overcoat at 7.4m2 per liter.(3) | 5 | 0 |
| Oriented Strand Board 10 mm nominal thickness, coated by SAFECOAT Latex ® with a single coat at a rate of 3.7 m2 per liter | 10 | 10-25 |
1FSR - flame spread rating
2SDC - smoke developed classification
3 Safecoat 725 is not a fire retardant but is used solely to change gloss and scrubbability
of the Safecoat Latex
NOTE: The flammability characteristics of different species of lumber vary. However, the practice of using Douglas Fir as a standard test substrate provides a basis for the comparison of various coatings. Oriented Strand Board (OSB) has a very high flame spread rating and as such requires an individual fire test as shown above. Do not extrapolate OSB Flame Spread rating based on Douglas Fir test results.
It is accepted that the above mentioned values for Douglas Fir can be attributed to other species of lumber predicted to have a flame spread of 100 or less providing the lumber is minimum nominal 25 mm thick. These other species include:
| Eastern White Pine | Western Hemlock |
| Lodgepole Pine | Western Red Cedar |
| Pacific Coast Yellow Cedar | Western White Pine |
| Select Red Oak | Flooring White Spruce |
