What is the purpose of this standard?

Its purpose is to provide a systematic checklist of potential functions (e.g., allow movement, provide fire resistance, offer acoustic insulation) that a building joint may need to fulfill.

Does this code provide design details for joints?

No, it is a guideline listing the 'what' (functions) not the 'how' (design calculations or material specifications). It helps in defining performance requirements.

What are some main functions of joints listed in the standard?

Key functions include accommodating dimensional variations, providing continuity of insulation (thermal/acoustic), ensuring weather tightness, and maintaining fire resistance.

This standard, adopted from ISO 3447-1975, provides a comprehensive checklist of the primary and secondary functions that joints in buildings are required to perform. It acts as a systematic guide for designers to ensure all performance criteria for joints, such as accommodating movement, providing weather sealing, and fire resistance, are considered during design.

Practical Notes

Use this checklist during the early design stages to create a performance specification for building joints (e.g., expansion, construction, control joints).

This document is not a design manual but a conceptual tool to ensure no functional requirement of a joint is overlooked before selecting materials and dimensions.

It is particularly useful for complex projects involving facade engineering or where different building materials with varying properties meet.
