This test method is intended to measure the amount of curl of a carbonless copy paper sheet relative to the flat surface supporting the sample. The test is useful as a quality control method and for predicting field performance.

1. Scope

1.1 This test method covers the determination of the curl of carbonless copy papers, that is, the degree of curvature of a sheet of these papers when exposed to varying conditions of humidity.

1.2 This test method may be used for manufacturing control, development, and research.

1.3 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
