ISI/BIS certification is mandatory for continuous (piano) hinges as per IS 3818:1992. Continuous hinges are pieces of hardware that extend the entire length of a door, panel or lid. They are sometimes called piano hinges because they closely resemble the long, thin design of piano lid hinges. These hinges are distinguished by their smooth, continuous construction and interlocking knuckles or leaves throughout their length. To allow easy opening and closing of a door, panel or lid, continuous (piano) hinges provide stable weight support and distribution. They are renowned for their strength and are often used on toolboxes, furniture, musical instrument cases and other items where regular movement, balanced weight distribution and dependable performance are important.
