wooden beds, Part 1: For use with mattresses
1988 Edition

As per IS 7259 Part 1, the permitted materials include seasoned solid wood species listed in IS 399-1963 suitable for furniture, adhering to moisture content standards defined in IS 287-1973 depending on climatic zone, and conforming to specifications in IS 1331-1977. Concealed parts made from non-durable wood require preservative treatment according to IS 401-1982. Additionally, plywood must meet IS 303-1975 standards, and medium density fibreboard (MDF) should comply with IS 12406-1988, using Interior Grade (IGSB) for air-drying finishes and Exterior Grade (EGSB) for oven-drying finishes. This ensures durability, dimensional stability, and environmental compliance.

IS 7259 Part 1 specifies that single beds should have a maximum height of 450 mm from floor to mattress top, clear in-bed length between 1900 and 2000 mm, and a width of 910 mm. Double beds share the same height and length range but have widths varying from 1525 mm to 1830 mm. The side and end rails measure 100 x 50 mm for single beds and 150 x 50 mm for double beds. Dimensional tolerances allow for ±10 mm overall deviation and ±5 mm difference between diagonal lengths to ensure squareness. Mortise and tenon joints are used for frame assembly, with optional recesses for mattress support panels.

The assembly of wooden bed components must utilize bed fittings, bolts with nuts, or screws securely fastened under pressure. Before inserting screws, pilot holes should be drilled, and screws dipped in adhesive for enhanced bonding, particularly when fixing head and footboards. Joinery practices must comply with IS 3845-1966, which details appropriate joint types and workmanship. Components should be sourced from seasoned timber conforming to IS 399-1963 and moisture content standards in IS 287-1973, with preservative treatment for concealed parts as per IS 401-1982. For knocked-down beds, components must be fully prepared for quick assembly, accompanied by clear illustrated instructions and packaged with waterproof wrapping to safeguard during transport.

The finishes on wooden beds must undergo various performance tests as outlined by IS 7259 Part 1 and referenced standards. These include resistance to dry heat (IS 1109 Part 1), wet heat (IS 1109 Part 2), marking by oils and fats (IS 1109 Part 3), marking by liquids (IS 1109 Part 4), and resistance to mechanical damage such as scratches, abrasion, and impact (IS 1109 Part 6). These tests ensure the surface coatings maintain aesthetic and functional integrity under typical usage conditions. Additionally, the wood used should be seasoned and preservative treated to enhance durability.

IS 7259 Part 1 mandates that timber used must originate from species listed in IS 13622:1993 and sourced exclusively from non-natural forests including industrial or social forestry plantations and shade trees from tea or coffee estates. Medium density fibreboard (MDF) must comply with IS 12406:1988, with Interior Grade (IGSB) used for air-drying finishes and Exterior Grade (EGSB) for oven-drying finishes. Products must bear the BIS Standard Mark and satisfy additional environmental criteria laid out by the Ministry of Environment and Forests for ECO Mark certification, ensuring sustainable sourcing and environmentally responsible manufacturing practices.
