Standard Test Methods for Determining Acceptability of Ribbon Welds in Fabric Cartridges
The test methods described can be used to evaluate acceptability of fabric ribbon welds on a comparative basis. Some, though not all, tests may also be used for manufacturing control. The weld durability test is exclusively for manufacturing control, since it involves in-process testing.
Users may choose to perform any or all of the tests described, depending upon results desired and equipment available.
1.1 These test methods are for evaluating ribbon welds in fabric cartridges that do not contain endless woven loops. These test methods apply to ribbon welds made with ultrasonic energy but do not cover special-purpose welds such as overlap or butt welds. Physical characteristics of ribbon welds and test performance may be used to predict acceptable function and printing life of the weld in the finished cartridge. These test methods are suitable both for comparative evaluations by end-users and for manufacturing control within the ribbon product industry.
1.2 Since types of ribbon welds and equipment vary, similar fabric cartridges may not contain the same type of ribbon weld. Any evaluation comparing products from different sources should note this.
1.3 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.
