Steel back flap hinges are very commonly used in furniture, tables, storage purposes, and
cabinets when opening ease is required. These types of hinges have been designed to join
panels together and function perfectly. The flap hinges are made from hard steel material and
have strong tensile strength and high holding capability. This prevents any kind of bending
during regular use. They come in small sizes and are also easy to install.
Certification by the Bureau of Indian Standards is necessary for the manufacture of steel back
flap hinges. IS 3843: 1995 lays down the tests for dimensions, quality, surface finish,
manufacturing standards and performance parameters of steel back flap hinges. Certification
ensures proper fitting and efficiency in their usage.
What is IS 3843: 1995
This is the Indian Standard for steel back flap hinges used in doors, shutters and cabinets. It
mentions the material specifications and manufacturing quality to ensure reliable performance
and durability of hinges. As per the BIS (Bureau of Indian Standards), these back flap hinges
are:
- Verified for material conformity
- Assessed for finish quality
- Evaluated for structural integrity
- Tested for durability
