1. Scope

1.1 This test method covers the procedure for testing the compatibility of lithographic ink resins in high boiling ink solvents by precipitation temperature.

1.2 This test method uses laboratory equipment generally available in a normal, well-equipped laboratory.

1.3 This test method is for use with ink resins intended mainly for oil-based offset and letterpress inks. The type of resins are typically, but not limited to C9 aromatic hydrocarbon resins, modified dicyclopentadiene resins, rosin pentaerythritol or glycerine esters, phenolic modified rosin esters, maleic anhydride modified-rosin esters, and naturally occurring resins such as gilsonite.

1.4 The typical high boiling solvents to be used are C12 to C16 petroleum distillates.

1.5 To avoid fire or injury to the operator, or both, this test method should not be used with low flash point solvents such as toluene or xylene. The minimum flash point of the solvents used should be 60°C (140°F) as determined by Test Method D 56.

NOTE 1--Users of this test method should be aware that the flash point of many solvents used for this test (as defined in Test Methods D 56 and D 1310) is exceeded in the heating cycle of this test method. Safety precautions should be taken since there is the potential for vapor ignition. The method outlined should be done in a shielded exhaust hood, where there is access to a fire extinguisher if needed.

1.6 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.
