According to the standard, the cabinet body must be constructed from mild steel sheets with a minimum thickness of 0.8 mm. The internal cages and shelves should be made from mild steel sheets at least 0.6 mm thick. Trays are also fabricated from mild steel with a thickness not less than 0.6 mm, featuring compressor plates and hinged rear flaps made from mild steel sheets with at least 0.8 mm thickness. These materials ensure strength and smooth operation of the indexing cabinets.
The specification defines three card sizes corresponding to cabinet types: Type 1 accommodates 150 x 100 mm cards, Type 2 is for 200 x 125 mm cards, and Type 3 fits 280 x 225 mm cards. Cabinets are designed to have 4, 7, or 14 trays, with height, width, and depth dimensions standardized according to these types and tray numbers. Additional trays can be added upon purchaser request, ensuring flexibility for different storage needs.
Corrosion protection is provided by applying a phosphating treatment to the mild steel components following the prescribed standards, immediately after pickling. This is complemented by enamel paint coatings conforming to specified Indian Standards. Durability is verified through a condensation corrosion test performed on treated steel samples, requiring no visible rust formation after exposure. These processes ensure the cabinets maintain their integrity in typical office environments.
While the standard does not explicitly detail performance tests for the cabinets, general good practices include load testing for structural strength, durability assessments through repeated operation of drawers, corrosion resistance evaluation of finishes, dimensional verification against tolerances, and confirmation of manufacturer marking legibility. These tests collectively ensure reliability, safety, and compliance with quality norms.
Purchasers need to specify the cabinet type (1, 2, or 3), the number and sizes of cards, the preferred type of card holders, the desired color and finish, and the number of trays required. This information allows manufacturers to customize and produce cabinets that meet the exact organizational and functional requirements. Additionally, cabinets can be tailored with extra trays and are packaged to avoid damage during shipment.
