ASTM F1444-00(2009) PDF

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

1.2 The Hobart 18VP Thermal Label Printer described in this test method may be used for specification acceptance, product development or research applications, or both, and manufacturing control.

1.3 Although a specific manufacturer has been identified for this equipment, any thermal label printer with equivalent signal output capabilities and sample size requirements would be suitable.

1.4 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.

1.5 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. (Warning - This test method requires making power adjustments and trigger printing while the protective cover is off, thereby exposing the user to electrical hazards.)
