ASTM D727-96(2006)

1.1 This test method covers the determination of the relative saturating capacity of felt papers for roofing and flooring.

1.2 The results are reported in terms of the kerosine number of the sample.

1.3 While the results reported are numerical, they are used only as a relative measure of the saturating capacity of felt papers, and this test method as generally used provides a qualitative means to differentiate and rank various papers which are to be subjected to bituminous saturation.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific warning statements are given in 10.5.

Felt papers for roofing and flooring are important in the construction industry. Felt papers with different end use properties can be made. The kerosine number is a relative measure of the amount of a bituminous saturant a lot of saturating grade paper is capable of absorbing, and is useful in choosing papers for specific levels of saturation or manufacture into specific end products. Generally, higher relative kerosine numbers based upon this test method are desirable.
