Which standards document includes the requirements for fire performance ratings?

The correct choice highlights that the standards document pertaining to fire performance ratings is found within the SB principles. These principles are established to ensure that building materials and assemblies meet certain fire safety criteria, including their ability to resist ignition, contribute to fire spread, and perform during fire exposure. The SB principles specifically address the necessary performance metrics for different materials based on their intended use in construction and the overall fire safety strategy of the building.

In contrast, the other choices do not specifically pertain to fire performance ratings. The SA guidelines may provide supplementary guidance or best practices, but they lack the comprehensive specifications found within the SB principles. The SC protocols, while potentially focusing on various construction standards, do not directly connect to fire performance ratings. Lastly, the Safety standards of Division A may cover broader safety issues in the building code, but they are not exclusively focused on the fire performance ratings as required by the SB principles. Understanding the relevance of the SB principles is crucial for anyone involved in evaluating or designing systems with regard to fire safety in buildings.
