ASTM F598 – Standard Practice for Determining the Resistance of Carbonless Papers to Capsular Damage (Withdrawn 2015)

1.1 The test procedures of this practice are applicable to any carbonless paper product that employs a coating of micro-capsules bondedto one side of the paper wherein the active material within the capsules isa colorless reactant capable of generating color when the capsules are brokenand the contained solution is simultaneously transferred to a reactive receptorsurface capable of changing the chemical from a colorless to a colored condition.

1.2 The procedures are designed to demonstrate the extent of damage incurred by (1) controlling therate of slippage of test units held in contact with each other under a calibratedweight and (2) by the controlled application of pressureto test units held stationary with respect to each other.

1.2.1 The first test procedure is designed to demonstrate the resistance to capsular damage related to plies slipping under pressure.

1.2.2 The second test procedure is designed to demonstrate the resistance to capsular damage related only to pressure, such as betweenplies within rolls, between sheets in a stack or due to nip effects in webprocessing, converting, or end-use equipment.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof whoever uses this standard to consult and establish appropriate safetyand health practices and determine the applicability of regulatory limitationsprior to use.
