ASTM F1445-00(2004)

This test method enables static thermal response comparisons between direct thermal media and facilitates process control.

Comparisons can be made between and within thermal media production lots from the same manufacturer.

Comparisons can be made between thermal media product grades from different manufacturers.

This test method is useful in predicting heat stability for end-use applications.

1.1 This test method covers the static thermal response of direct thermal papers to determine uniformity within and between lots. This test method can also be used to test other direct thermal products with substrates other than paper.

1.2 The instrument described in this test method may be used for specification acceptance, product development or research applications, or both, but its primary use is for manufacturing control.

1.3 The values stated in either inch-pound or SI units are to be regarded separately as the standard. The values given in parentheses are for information only.

1.4 This standard does not purport to address all of the safety problems, 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.
