IS 8467 outlines the specifications for steel card-index cabinets, encompassing types, construction, finishing, and marking standards. Cabinets may display the ISI Certification Mark, reflecting adherence to inspection and quality controls. The standard employs SI units such as meters for length, kilograms for mass, newtons for force, and pascals for pressure. Purchasers must specify cabinet type, compressor plate and guide rod requirements, finish color, locking mechanism preferences, and any alternative construction or finishing methods. Test results should be rounded according to IS 2-1960 to maintain precision.
This section defines terms relevant to steel card-index cabinets to ensure uniform understanding during manufacturing and inspection. It also specifies the use of SI units—metre, kilogram, second, ampere, kelvin, candela, mole, radian, and steradian—for all measurements. Derived units like newton (N) for force, joule (J) for energy, watt (W) for power, and pascal (Pa) for pressure are detailed. Marking provisions and order specifications reiterate purchaser responsibilities.
Steel sheets used in cabinet construction must comply with IS 513:1973 or IS 1079:1973 standards. Purchasers should indicate cabinet type, compressor plate and guide rod needs, finish color, locking arrangements, and any alternative methods. The document emphasizes the use of SI units for all technical parameters and confirms that ISI certification assures ongoing quality control and inspection throughout production.
Welding fillers and electrodes used in manufacturing must conform to IS 1278:1972 for gas welding rods, IS 814 (Part II):1974 for covered electrodes in arc welding, and IS 4972:1968 for resistance spot-welding electrodes. Mild steel sheets for electrode fabrication must meet IS 513:1973 or IS 1079:1973. Data cards for welding records have defined dimensions. Test results shall be rounded as per IS 2-1960 guidelines.
Dimensions are standardized for three cabinet types: 2-drawer, 4-drawer, and 11-drawer models, with specific heights, widths, and depths corresponding to card sizes 105x74 mm, 148x105 mm, and 210x148 mm. Minimum inside drawer depths are 460 mm for 2- and 4-drawer cabinets and 610 mm for the 11-drawer type. Guide rods must have a minimum diameter of 5 mm. Vertical and horizontal stiffeners are integral to the cabinet design.
Purchasers must specify cabinet type, compressor plate and guide rod requirements, finish color, locking arrangement, and alternative construction or finishing methods. Paints and finishes must comply with relevant IS standards for enamel coatings and primers. Cabinets may bear the ISI mark to certify quality compliance. All measurements and testing utilize SI units, and results must be rounded according to IS 2-1960.
Post-pickling, mild steel components receive phosphating treatment conforming to IS 3618:1966 Class C and IS 6005:1970 guidelines. A primer coat such as red oxide is applied, followed by two enamel paint coats consisting of an undercoat and finishing coat in accordance with specified IS standards. Surface filling putty must meet IS 426:1961. Aluminium primers, if used, must comply with IS 2931:1964. Purchasers should specify finish type, color, and other construction preferences.
The finish must meet purchaser specifications including compressor plate and guide rod features, finish color, and locking mechanisms. Testing results are rounded per IS 2-1960 to maintain required significant figures. Various paint standards are referenced to ensure protective and aesthetic coating quality. Compliance is verified through testing, with ISI marking confirming adherence to quality norms.
Purchasers must provide product specifications including compressor plate and guide rod needs, finish color, locking arrangements, and any alternative methods. Test results must be rounded following IS 2:1960. Test cards have defined sizes for consistency. SI units are used throughout for parameters such as length, force, pressure, energy, and power. The testing flow ensures products meet standard requirements before acceptance.
All steel card-index cabinets must bear a manufacturer’s identification mark, which should be durable and legible. Cabinets may also display the ISI Certification Mark, indicating conformity with Indian Standards under ISI oversight. The use of the ISI mark is regulated by the Indian Standards Institution and assures continuous quality inspection. Purchasers should specify cabinet type, compressor plate, guide rod, finish color, locking method, and alternative construction if any.
Manufacturer identification marks are mandatory on all cabinets, with optional ISI Certification Marks indicating compliance and quality control. Markings must be permanent and clear, facilitating traceability. Specifications relating to cabinet type, compressor plate and guide rod requirements, color, locking arrangements, and alternative methods must be provided by the purchaser. SI units are consistently applied in all measurements and documentation.
Frequently Asked
IS 8467 defines standard measurements for steel card-index cabinets according to drawer quantity and card size. For 2-drawer cabinets with card sizes 105x74 mm, 148x105 mm, and 210x148 mm, heights are 130 mm, 165 mm, and 205 mm respectively; widths are 275 mm, 370 mm, and 490 mm; depths are uniformly 510 mm. Four-drawer cabinets have heights of 255 mm, 315 mm, and 380 mm for the same card sizes with identical widths and depths. The 11-drawer cabinet is sized at 1335 mm height, 305 mm width, and 700 mm depth for 105x74 mm cards. Minimum drawer depths are 460 mm for 2- and 4-drawer types and 610 mm for 11-drawer types, with guide rods at least 5 mm in diameter.
The cabinet bodies and drawers must be constructed from steel sheets with a minimum thickness of 0.8 mm as per IS 8467. The cabinet body incorporates horizontal and vertical stiffeners to separate drawer compartments and enhance rigidity. Drawers include locking mechanisms to secure them in the fully retracted position and allow removal when unlocked, ensuring operational reliability.
Surface treatment begins with pickling to remove contaminants, followed immediately by phosphating treatment compliant with Class C of IS 3618:1966 and performed as per IS 6005:1970. A primer coat, commonly red oxide, is applied next, followed by two enamel paint coats: an undercoat and a finishing coat adhering to IS paint standards. Surface imperfections are filled using putty conforming to IS 426:1961. Aluminium primers may be applied if specified, meeting IS 2931:1964 standards. This multi-step process ensures effective corrosion protection.
Locking systems must allow for either simultaneous or individual locking of drawers using duplicate keys. The design must prevent insertion of tools through gaps between the drawer fronts and cabinet body or stiffeners to manipulate the lock. Drawers, constructed from steel sheets at least 0.8 mm thick, should lock securely when fully retracted and be removable upon unlocking. The cabinet structure includes horizontal and vertical stiffeners for compartmentalization and security. Additional features include movable compressor plates or guide rods to support drawer operation and security.
IS 8467 mandates that steel card-index cabinets must endure a uniformly distributed compressive load of 300 newtons on the top surface without suffering permanent deformation. The cabinet should remain stable on a flat surface during this test, and drawers must continue to operate smoothly under this load. The cabinet must be fabricated from steel sheets at least 0.8 mm thick with appropriate stiffeners to ensure durability and structural integrity.
