Subject : Omega Point Laboratories Test Report
          "FX-100^® FIRE PROTECTIVE COATING" on plywood panels
 

The March 24, 1994 test was performed to show the fire performance of FX-100^® COATING when applied to standard decking material (1/2" CDX PINE PLYWOOD) with a worst case scenario included which involved the primary flame impingement being a "joint" in the system. You will notice that there were six panels used, each 24 inches in length. This placed a joint at the point of contact of the test flame in the furnace.

Note that the test did prove similar performance as the U.L. E-84 performed on Douglas Fir where the flame impingement was not at a joint. The intumescent expansion performed well in that it covered over the small gap at the joints.  The flame spread was almost identical to the U.L. test with the only difference being that slightly more smoke was evolved from the test sample when the joint was first exposed to the flame as the heat affected the ends of the test pieces until sufficient intumescent expansion insulated the material.

I.  INTRODUCTION

This report describes the results of the ASTM E84-91a Standard Test Method for SURFACE BURNING CHARACTERISTICS OF BUILDING MATERIALS (1),  a method for determining the comparative surface burning behavior of building materials. The test is applicable to exposed surfaces, such as ceilings or walls, provided that the material or assembly of materials, by its own structural quality or the manner in which it is tested and intended for use, is capable of supporting itself in position or being supported during the test period.

The purpose of the method is to determine the relative burning behavior of the material by observing the flame spread along the specimen. Flame spread and smoke density developed are reported, however, there is not necessarily a relationship between these two measurements.

"The use of supporting materials on the underside of the test specimen may lower the flame spread index from that which might be obtained if the specimen could be tested without such support... This method may not be appropriate for obtaining comparative surface burning behavior of some cellular plastic materials... Testing of materials that melt, drip, or delaminate to such a degree that the continuity of the flame front is destroyed, results in low flame spread indices that do not relate directly to indices obtained by testing materials that remain in place."

This test method is also published under the following designations:

II. PURPOSE
 

The ASTM E84-91a  (25 foot tunnel) test method is intended to compare the surface flame spread and smoke developed measurements to those obtained from tests of mineral fiber cement board and select grade red oak flooring. The test specimen surface (18 inches wide and 24 feet long) is exposed to a flaming fire exposure during the 10 minute test duration, while flame spread over its surface and density of the resulting smoke are measured and recorded. Test results are presented as the computed comparisons to the standard calibration materials.

III.   DESCRIPTION OF TEST SPECIMENS
    Specimen Identification:  "FX-100^®" Intumescent Fire Retardant Coating

IV.  TEST RESULTS

The test results, computed on the basis of observed flame front advance and electronic smoke density measurements are presented in the following  table.  In recognition of possible variations and limitations of the test method, the results are computed to the nearest number divisible by five, as outlined in the test method.

While no longer a part of this standard test method, the Fuel Contributed Value has been computed, and may be found on the computer printout sheet in the Appendix.
 

The data sheets are included in the Appendix. These sheets are actual print-outs of the computerized data system which monitors the ASTM E84 apparatus, and contain all calibration and specimen data needed to calculate the test results.

V. OBSERVATIONS

The coating became intumescent at 0:08 (min:sec). Sample ignition was observed through the tunnel windows, and occurred at approximately 0:30 (min:sec). Char formed a thickness of 1" at 1:00(min:sec), 1.5" at 1:15(min:sec), 2" at 2:05(min:sec), 3" at 3:25(min:sec), and 4" at 4:15(min:sec).  Maximum flame spread of 2.0' occurred at 9:46(min:sec).

After cooling and removal from the tunnel, the specimen was observed as follows: The coating was intumescent to 24', and was approximately 3" thick. Channels had formed in the intumescent coating at 2', 4', 6', 8', 10', 12', 16' and 20', thus exposing the substrate (plywood) and allowing char to form on the plywood.  Partial consumption of the plywood was noticed between 4'and 5'.
