Standard Test Method for Determining Winding Torque and Tension of Typewriter Ribbons (Withdrawn 2016)
|Publication Date:||1 October 2010|
|ICS Code (Office machines):||35.260|
significance And Use:
This test method enables tension and torque comparisons between cartridges and facilitates process control.
1.1 This test method covers the determination of film ribbon cartridge wind tension and torque. The instruments described in this procedure may be used for specification acceptance, manufacturing control, product development, or research applications, or combination thereof.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 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.
