Name the type of mark for which we should look at an electrical appliance before buying

When looking at an electrical appliance before buying, there are several marks or labels that you should consider. These marks indicate the safety and quality standards of the appliance. One important mark to look for is the "CE" mark. The CE mark indicates that the appliance meets the essential requirements of European health, safety, and environmental protection legislation. It ensures that the appliance has undergone testing and complies with the necessary standards. Additionally, you should also look for the "UL" mark, which stands for Underwriters Laboratories. This mark is commonly found on electrical appliances in North America and indicates that the product has been tested and certified for safety by an independent organization. Other marks to consider include the "Energy Star" mark, which indicates that the appliance is energy-efficient, and the "RoHS" mark, which indicates that the appliance is free from certain hazardous substances. By checking for these marks, you can ensure that the electrical appliance you are buying meets the necessary safety and quality standards.
