According to the standard IS 2695:1993, the maximum allowable overall sizes for filing cabinets are specified as follows: Two-drawer units measure up to 750 mm in height, 700 mm in depth, and 470 mm in width; three-drawer units are sized at 1080 mm high, 700 mm deep, and 470 mm wide; and four-drawer units reach 1330 mm in height with the same depth and width. Installation requires minimum clearances of 20 mm above the cabinet, 10 mm on both sides, and 5 mm in depth to ensure proper fit and function. These dimensions adhere to IS 3313:1983 for metal filing cabinets and require secure fastening of components to maintain structural integrity.
The standard mandates that materials used in the fabrication of drawing filing furniture must comply with the specifications outlined in Clauses 4.1.1 through 4.1.6. Only upon agreement between the purchaser and manufacturer can alternative materials be considered. Metal filing cabinets should conform to IS 3313:1983 requirements. Additionally, pockets used in lateral filing systems must be constructed from robust, durable materials suited for frequent handling. Typical materials include selected metals, approved types of wood, and certain plastics as specified within the standard.
IS 2695 specifies that drawers, whether wooden or steel, must operate smoothly even when fully loaded. Wooden drawers should be suspended on mechanisms like rollers or smooth runners to facilitate effortless sliding. Steel drawers require cantilevered ball-bearing slides or channels that allow full extension and smooth movement. Drawers must be equipped with stops to prevent accidental pull-out while enabling visibility of contents, and safety features to prevent finger injuries during operation. The cabinet structure, including the plinth and top, must be firmly secured to maintain alignment and support smooth functionality.
The standard references finishing processes such as powder coating in accordance with IS 13871:1993 for mild steel components. Durability verification typically involves tests including adhesion (cross-cut or tape test), salt spray to assess corrosion resistance, impact resistance tests to evaluate mechanical robustness, abrasion resistance tests, and humidity exposure to check for blistering or peeling. These tests ensure the finish provides long-lasting protection and appearance. Detailed procedures are specified in IS 13871 and related testing standards to confirm compliance.
Vertical filing cabinets are designed with specific clearances and filing methods to store drawings of different dimensions from A0 to A3 efficiently. Larger drawings can be suspended by pins or prongs from their longer edges or held horizontally under compression pressure, depending on size. Drawings of various sizes can be filed together in the same unit with appropriate dividers to separate sizes and prevent damage or slippage. The filing orientation and cabinet dimensions are designed to correspond with standard drawing sizes, ensuring ease of access and protection.
