Bio-SIP™ Small Flame Test Achieves Milestone in Fire Safety Testing

Bio-SIP™ Small Flame Test

The innovative Bio-SIP™ has recently passed the small flame test EN ISO 11925-1 at BRE in Watford, marking a significant milestone in its development and showcasing its advanced fire resistance capabilities. This accomplishment not only highlights the superior design of Bio-SIP™ but also sets the stage for more rigorous testing in the future.

Understanding the EN ISO 11925-1 Small Flame Test

The EN ISO 11925-1 small flame test is a crucial initial assessment in the fire testing of building materials. This test evaluates the ignitability of building products when exposed to a small flame, such as a match or a lighter. During the test, a small flame is applied to the surface or edge of a specimen for 30 seconds to observe whether the material ignites and how it behaves under such conditions.

Benefits of the EN ISO 11925-1 Test

  • Early Stage Screening: Provides essential data on material performance in severe fire scenarios, helping manufacturers improve their products.
  • Safety Assurance: Demonstrates the material’s ability to resist ignition, a critical factor in fire prevention.
  • Regulatory Compliance: Compliance with EN ISO 11925-1 is often a prerequisite for further testing and certification, ensuring the material meets basic fire safety standards.

From Small Flame to Single Burning Item Test

Following its success in the small flame test, Bio-SIP™ is now set to undergo the more severe Single Burning Item (SBI) test, EN 13823. This comprehensive test measures:

  • Heat Release: The amount of heat generated during combustion.
  • Smoke Production: The quantity and density of smoke emitted.
  • Lateral Flame Spread: The extent to which flames spread across the material’s surface.
  • Burning Droplets/Particles: The presence and behavior of burning particles or droplets.

The Quest for Class C: Bio-SIP™ Fire Safety Testing

Achieving a Class D rating is already a significant achievement for Bio-SIP™, surpassing traditional Structural Insulated Panels (SIPs), which are typically rated Class F. Class F materials, often composed of dried wood with petroleum-based insulation, are highly flammable. In contrast, Bio-SIP™ estimated Class D rating indicates a lower contribution to fire, offering a safer alternative for construction.

The objective now is to elevate Bio-SIP™ to a Class C rating through the SBI test. A Class C rating would further affirm the material’s superior fire resistance, ensuring it ignites less easily and minimises the spread and intensity of fire, thus enhancing overall building safety.

Advantages of Achieving a Higher Fire Rating

  • Enhanced Safety: Greater protection for occupants, as the material will contribute less to fire growth and spread.
  • Market Competitiveness: A higher fire rating can make Bio-SIP™ more attractive for construction projects where fire safety is a critical concern.
  • Environmental Impact: Improved fire resistance underscores Bio-SIP™’s role as a sustainable building material, potentially reducing the environmental impact associated with fires.

The successful passing of the EN ISO 11925-1 small flame test marks a significant step forward for Bio-SIP™ Fire Safety Testing, demonstrating its superior fire resistance compared to traditional SIP panels. As Bio-SIP™ advances to the more rigorous Single Burning Item test, there is optimism that it will achieve a Class C rating, further solidifying its position as a safer, more reliable choice in building materials. This progression not only reflects the innovative design and composition of Bio-SIP™ but also its potential to revolutionise fire safety standards in the construction industry.

Bio-SIP™ is used in the Qube Buildings construction of leisure buildings and garden offices.
