scope:

1.1 This test method measures the angle of contact when a drop of liquid is applied to the surface of a specimen of paper.

1.2 The measurement of both the initial angle of contact and the angle of contact after a defined elapsed period of time may be measured.

1.3 A standard liquid (ink) for making measurements is described.

1.4 Other liquids including printing inks, writing inks, adhesives, oils, and coating materials may be used upon agreement of those involved in the testing being done.

1.5 Two types of apparatus for measuring the contact angle using the procedure in this test method are described. Additional instruments that can perform the procedure in this test method may also provide equivalent results. A different procedure using an automated instrument for measuring angle of contact will be found in Test Method D 5725

1.6 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.7 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.
