Recommendations for co-ordination of dimensions in buildings-Arrangements of building components and assemblies, Part 5: Functional group 5 Fixtures, furniture and equipment
1974 Edition

The section outlines the scope of IS 7564 Part 5, focusing on dimensional coordination specifically within Functional Group 5, which includes fixtures, furniture, and equipment. It defines the concept of basic size as the reference for setting size limits and highlights the necessity of dimension coordination to ensure functional compatibility among components. Key tables provide recommended coordinating dimensions such as length, width, height, and thickness across domestic, commercial, and community applications, with components categorized by priority grades A, B, and C. Notes emphasize that certain dimensions are measured above floor level and include cross-references to other functional groups to support integrated design approaches.

This section clarifies essential terms including 'basic size,' which is the reference dimension fixing component limits, and defines Functional Group 5 as encompassing fixtures, furniture, and equipment. It presents grading criteria for components and details the coordinating dimensions from length, width, height, to thickness, accompanied by notes and cross references to other functional groups for detailed dimensioning guidelines.

Explains the classification of components into Grades A, B, and C based on the necessity of dimensional coordination—Grade A requiring strict coordination, Grade B needing it in certain instances, and Grade C not requiring coordination. The basic size concept is reiterated as the foundation for setting dimensional limits. Examples illustrate the application of coordinating dimensions for domestic living components such as benches, chairs, and appliances, highlighting the importance of grading in guiding design precision and tolerance.

Details the principles governing dimensional coordination, including grading definitions and the focus on length, width, height, and thickness parameters. It stresses the importance of modular dimensions and standardization, with guidance on tolerances applicable to different grades. Practical examples demonstrate typical modular dimension tables and how grading influences design flexibility.

Presents the advised coordinating dimensions for fixtures, furniture, and equipment across diverse functional activities such as domestic living and commercial services. The section includes tables with grading information, dimensional ranges, and notes on measurement specifics, such as height dimensions taken above floor level. It clarifies the significance of grading in prioritizing critical dimensions for design coordination.

Discusses how Functional Group 5 components relate dimensionally to other groups within the modular coordination framework. It explains grading and coordinating dimensions and provides examples of cross-references that ensure cohesive integration between fixtures, furniture, and allied building elements like plumbing or structural components, facilitating seamless design interoperability.

Outlines the concept of modular coordination as the alignment of dimensions among multiple building products to guarantee proper fit and function. It lists the functional groups involved and their respective roles, details component grading, and suggests the adoption of modular units (e.g., 100 mm or 300 mm increments) to streamline design, manufacturing, and installation. The section references British standards as foundational influences.

Explains the concept of coordinating space allocated to components, which includes allowances for manufacturing tolerances and joint clearances. It categorizes tolerances and clearances according to component grading and provides typical allowance values. A formula is given for calculating coordinating space, ensuring components fit properly with sufficient clearance for assembly.

Provides selected examples of recommended coordinating dimensions for various fixtures, furniture, and equipment categorized by functional activity like domestic catering, laundering, and personal dressing. Tables include grading, dimensional data, and cross-references to support comprehensive design coordination.

Focuses on coordinating dimensions within building assemblies, emphasizing modular coordination with structural grids and standard module sizes to facilitate component interchangeability and ease of installation. It covers clearance requirements and recommends early coordination with architectural and structural plans to prevent conflicts, promoting efficient assembly and maintenance.
