IS 7564:2000 (Part 5) is the Indian Standard (BIS) for recommendations for co-ordination of dimensions in buildings-arrangements of building components and assemblies, part 5: functional group 5 fixtures, furniture and equipment. This standard provides recommendations for the dimensional coordination of fixtures, furniture, and equipment within buildings. It specifies coordinating sizes and arrangement principles to ensure functional and efficient use of space, particularly for kitchens, bathrooms, bedrooms, and offices.

Key Differences
≠IS 7564 provides specific preferred dimensions for structural components (e.g., column sizes 300x300, 300x400 mm), whereas modern ISO standards like ISO 21723 focus on defining the principles (the module) and leave specific application dimensions to designers.
≠IS 7564 is structured as a series of parts for different 'Functional Groups' (Part 1 for Structures). The international approach has moved away from this rigid functional grouping towards more principle-based general standards.
≠The Indian standard is a 'Recommendation', and its application in practice is inconsistent. While ISO standards are also voluntary, their adoption within the European Union (as EN ISO standards) or in major international projects can lead to more consistent application.
≠The specific examples and preferred dimensions in IS 7564 are tailored to construction materials and practices common in India (e.g., reinforced concrete frames), which may differ from priorities in regions with different dominant construction systems (e.g., timber or steel framing).
Key Similarities
≈Both IS 7564 and the international standards (from ISO 2848 to ISO 21723) are fundamentally based on the same basic module 'M' of 100 mm.
≈The use of multimodules (multiples of the basic module, such as 3M, 6M, 12M, 30M) for establishing larger scale dimensions like structural grids and building layouts is a core shared principle.
≈Both systems explicitly define and differentiate between 'co-ordinating dimensions' (the ideal modular space for a component) and 'work size' or 'basic size' (the actual manufactured dimension), accounting for joints and tolerances.
≈The hierarchical approach to design is identical: establishing large-scale planning grids first, followed by vertical dimensions (storey heights), and finally the sizing of individual components, all derived from the modular system.
