Structure
This section outlines the scope of the standard, specifying the quality, safety, and dimensional norms for wooden office tables. It includes provisions for ISI certification marking, the use of SI units for measurements, guidelines on rounding test results per IS 2:1960, and sampling and testing protocols following IS 5967:1969.
Details on material requirements cover ISI certification adherence, surface finish tests based on the IS 5807 series, physical and mechanical property expectations, and ergonomic considerations per IS 3663:1981. The section provides a summary table highlighting key material characteristics and their respective testing standards.
This part addresses dimensional limits and allowable tolerances as integral to type testing. It emphasizes the use of SI units, rounding conventions per IS 2:1960, and typical tolerance ranges for length, width, height, and panel thickness to ensure proper fit and interchangeability.
Specifications for adhesives used in joinery include compliance with IS 4835-1979 for polyvinyl acetate dispersions and IS 849-1957 for cold setting casein glue. The section also covers finishing adhesives and mandates adhesion testing in line with IS 5967-1969.
Requirements for surface finishes such as waxing, French polishing, varnishing, and painting are described, with adherence to IS 2338 (Part 1)-1967. The section details tests for resistance to dry and wet heat, oils, liquids, and mechanical damage, referencing IS 5807 parts 1 through 6.
This section summarizes mandatory tests including dimensional verification, glue adhesion strength, physical integrity checks, mechanical resistance, and surface finish durability. It references IS codes such as IS 3663-1981, IS 1734 (Part 5)-1983, IS 5967-1969, and IS 5807 (Parts 1-6).
General mandates include compliance with dimensional and strength parameters, sampling and testing per IS 5967:1969, and the optional use of the ISI certification mark regulated under Indian Standards Institution rules. SI units are prescribed for all measurements.
This section elaborates on routine and type testing requirements, sampling methods, and detailed test criteria for dimensions, adhesion, physical and mechanical properties, and surface finishes. It also reiterates marking and measurement units.
Guidance on packaging emphasizes adherence to conventional trade practices to safeguard tables during transport. Marking provisions allow for optional ISI certification marks that confirm quality assurance and ongoing inspection.
Buyers must specify the type, shape, size, color, and finish of wooden tables in their orders to ensure precise fulfillment. This section also references packing norms and marking options.
This final section describes the criteria for ECO Mark certification, including requirements for sustainable timber as per IS 12406:1988, manufacturer declarations, environmental clearances, and BIS certification processes to promote eco-friendly furniture production.
Frequently Asked
The standard does not explicitly enumerate wood types or grades, but common practice includes durable hardwoods such as teak, sal, sheesham (Indian rosewood), and occasionally mango wood. The timber should be well-seasoned, free from knots and defects, with moisture content maintained between 8-12% to prevent warping. Compliance with IS 1708 for seasoning and grading is recommended to ensure quality and durability.
In accordance with the standard and IS 3663:1981, the typical table height is approximately 750 mm. Minimum legroom dimensions include a width of at least 600 mm, a height of at least 650 mm, and a depth of at least 450 mm, providing ergonomic comfort and sufficient space for users.
Adhesives used must conform to IS 4835-1979, which covers polyvinyl acetate dispersion adhesives, and IS 849-1957, which specifies cold setting casein glue. These adhesives ensure strong bonding, resistance to separation, and adherence to quality standards outlined in IS 1734 (Part 5). Proper joint design as per IS 3845-1966 is also essential.
Surface finishes must undergo tests including resistance to dry heat and wet heat with minimum average ratings of 7 (IS 5807 Parts 1 and 2), marking resistance by oils and fats where test spots should be indistinguishable (IS 5807 Part 3), marking resistance by liquids with a minimum rating of 8 (IS 5807 Part 4), and resistance to mechanical damage as per IS 5807 Part 6. These assessments ensure the finish maintains appearance and durability under typical conditions.
The standard incorporates sustainability by mandating compliance with ECO Mark criteria, requiring manufacturers to obtain environmental consents from pollution control boards, and restricting timber sources to those specified in IS 13622:1993 from sustainable plantations. Documentation and certification processes with BIS ensure transparency and promote eco-friendly manufacturing practices.
