SATURATING PROPERTY OF ROOFING AND FLOORING FELT (KEROSINE NUMBER)
23-07-2013
12-01-2013
This test is used to determine the relative saturating capacity of felt for roofing and flooring. The kerosine number of roofing and flooring felt is computed from the maximum weight of kerosine of known specific gravity retained by the felt after displacement of all the air from the interior voids. It is the number of milliliters of kerosine held per 100 g of felt and thus is a measure of the quantity of saturant that a given felt will absorb. A high kerosine number is considered desirable.
