BIS CERTIFICATION FOR CONTINUOUS (PIANO) HINGES IS 3818:1992

ISI/BIS certification is obligatory for continuous (piano) hinges under IS 3818:1992. Continuous hinges are hardware components that span the entire length of a door, panel, or lid. They are sometimes referred to as piano hinges due to their resemblance to the long, slender design of piano lid hinges. These hinges are characterized by their seamless, uninterrupted structure and interconnected knuckles or leaves along their length. Continuous (piano) hinges offer stable weight support and distribution, facilitating effortless opening and closing of doors, panels, or lids. Renowned for their durability, they are commonly utilized in toolboxes, furniture, musical instrument cases, and other applications where consistent movement, even weight distribution, and reliable performance are crucial.
