Oxygen index (OI) and horizontal burning rates at atmospheric oxygen concentration were studied with emphasis on fabrics with low add-ons of the retardants. OI values increased as add-ons increased; however, the OI values were increased about twice as much by 2% add-on at low levels of add-on as with 2% at high levels of add-on.

able to predict the residence time and burning rate on a surface-area basis with reasonable accuracy for pine needle beds. Unfortunately, the model did not per-form well for beds of vertical wood dowels. Also problematic was the prediction of the transition between burning regimes and the burning rate on a horizontal surface-area basis.

Test to determine the vertical burning rate of materials (Annexe 8) The rectangular sample is held vertically in a sample-holder, which allows placing 3 horizontal thread markers at 220 mm, 370 mm and 520 mm from the lower edge of the specimen. A 20 mm flame, inclined at 30° from the vertical, is applied for 5s on the sample.

Horizontal Burning Test (94HB) This is the easiest test to pass and materials that pass the vertical burning test will usually be acceptable for applications that require a HB r only. The test involves applying a flame to one end of a horizontal bar of the plastic for 30 seconds or until the flame front reaches the specified mark.
