PGDQ2.MH15654: Marking and Labeling Systems - Component
Underwriters Laboratories Standard UL 969: Underwriter’s Laboratory Has Defined a Standard For Marking and Labeling Systems. Per UL the scope of this standard is as follows:
| |
1.1 These requirements cover adhesive attached labels for use as nameplates or markers; bearing information, instructions, or identification. An adhesive for a label may be pressure sensitive, heat activated, or solvent activated. These labels are intended to be used by manufacturers for application to their products at their place of manufacture.
1.2 These requirements also cover unprinted materials, such as face stocks, label stocks, overlaminations, laminating adhesives, and inks used by label printers to produce labels.
1.3 These requirements apply to marking and labeling systems used on complete devices, appliances, or equipment. The acceptability of a system in a particular application is to be judged under the applicable requirements in the standard covering the device, appliance, or equipment on which the system is used.
1.4 Marking and labeling systems are evaluated for application to specific surface materials that are essentially smooth and flat unless another surface configuration is specified by the manufacturer. |
