ASTM F1721 – Standard Practices for Determining Stability of Direct Thermal Imaging Products (Withdrawn 2015)

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:

Scope	1
Referenced Documents	2
Terminology	3
Practices
Solvent Resistance	4–11
Light Stability	12–18
Heat and Humidity Stability	19–25
Keywords	26

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.
