The South African National Standard SANS 10400 (consisting of various parts A to W) is the application of the NBR (National Building Regulations) Act 103 of 1977.

SANS 10400 establishes functional requirements for various construction and occupancy activities around buildings to satisfy the NBR. As we are mostly interested in Fire Detection and Alarm Systems and Gaseous Fire Extinguishing Systems, our focus lies primarily with the following Parts of SANS 10400:

  • A (General principles and requirements)
  • S (Facilities for persons with disabilities)
  • T (Fire protection)
  • W (Fire installation)

The primary concern of SANS 10400 is to ensure that a healthy and safe environment is provided for occupants of buildings during the various phases of the building.
