Building Safety: ASTM Classifications for Temporary Construction Walls

Updated October 25, 2024

In the ever-evolving landscape of commercial construction, understanding fire safety standards is more than a requirement—it’s a commitment to excellence and safety. For temporary construction walls and other building materials, being aware of ASTM E84 and ASTM E119 classifications is essential for compliance and safety.

Deciphering ASTM E84: The Role of ASTM A & C Classifications in Temporary Wall Systems

ASTM E84, known as the Standard Test Method for Surface Burning Characteristics of Building Materials, measures the flame spread and smoke development indices. This is critical for selecting temporary wall systems that meet safety standards.

• ASTM A Classification: This refers to a flame spread index of 0-25. Materials with this classification are considered the best performers in terms of limiting flame spread and smoke generation. It’s often required for temporary walls in corridors, exits, and other critical areas, especially in healthcare facilities.
  
  
• ASTM C Classification: This indicates a flame spread index of 76-200. Materials under this classification have a higher potential for flame spread than ASTM A materials. They are typically used in less critical areas with lower occupancy density or traffic, where stricter fire performance criteria are not mandatory.
  
  

ASTM E119 and Temporary Wall Systems

ASTM E119, or the Standard Test Method for Fire Tests of Building Construction and Materials, is distinct from ASTM E84. It measures a building element’s (like a wall, column, or floor) ability to withstand fire exposure while maintaining structural integrity. Unlike ASTM E84, it provides a fire-resistance rating in hours, which is crucial for assessing temporary construction walls and other building components.

Understanding these classifications is essential to ensure compliance and safety in commercial construction projects. To learn how STARC’s temporary walls meet fire safety requirements, download our infographic, Fire Safety & Temporary Walls: One Critical Question.
