Significance and Use
These procedures enable comparison of samples with a control under various solvent conditions to determine the stability of the image. The various solvents simulate conditions which may be encountered in the environment.
The test may be used to judge which materials are suitable for a specific situation and usage. The sensitivity of the products should match and the products should be for the same application.
The procedure may be used for the evaluation of direct imaging coatings on paper, film, or other substrate. The method of imaging should be with the type of imaging unit for which the product has been designed.
1.1 These practices cover the evaluation of the effect of various solvents, light, heat, and humidity on direct thermal imaging products.
1.2 These practices may be used to evaluate the performance of thermal products coated on paper, film, or other substrate for specific applications.
1.3 These practices may be used for manufacturing control, development, and research.
1.4 The sections in these practices appear in the following sequence:
|Heat and Humidity Stability||19–25|
1.5 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.
1.6 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.
