ASTM F1721-04 - 1.2.2004
 
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. Scope

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.
