If the UL determines that the product meets all applicable requirements, the authorized manufacturer applies the UL authentication flag to the product or component. Once the company is allowed to apply the UL certification mark to its product or components, the label must be reviewed to ensure that they meet the basic requirements of UL settings.
The plan supervises the tag review by determining the actual performance of the label in the end user level. There are many factors that determine if a label will approve. The most important thing is the material used to make labels.
One of the worrying issues is how the brand may bear in the market. The label is often exposed to moisture, heat and oil, which may damage them. It is because of these factors, only some materials are available to UL authorized manufacturers to print manufacturing UL labels.
