The ISI mark is a certification mark issued by the Bureau of Indian Standards (BIS) in India. It indicates that a product meets specific quality and safety standards set by the BIS. This mark is commonly found on various products, including electrical appliances, food items, and construction materials, ensuring consumers that they are purchasing reliable and safe goods. Obtaining the ISI mark involves rigorous testing and evaluation of products to ensure compliance with established standards. Manufacturers must apply for certification, and once granted, they can display the mark on their products, helping consumers make informed choices while shopping.
