ASTM D 5909 : 1996 : REV A : R2006

CONTAINED IN VOL. 06.02, 2017 Describes the procedure for determining the drying time of oxidative-drying printing inks (also referred to as 'sheetfed inks') by squalene resistance of printed ink films.

1.1 This test method covers the procedure for determining the drying time of oxidative-drying printing inks (also referred to as "sheetfed inks") by squalene resistance of printed ink films.

1.2 This test method is applicable to all paste inks that dry primarily by oxidation regardless of the substrate on which they are printed. With appropriate changes in the test fluid, it may also be used with paste inks that dry by other mechanisms, such as heatset or ultraviolet light.

1.3 This test method utilizes a modified rub tester and is intended to serve as a "referee" procedure when laboratories, using less rigorous test procedures (see Appendix X1), cannot agree on their results.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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.
