Fire Propagation Testing
NFPA 285 – Fire Test for Wall Assemblies
NFPA 285 evaluates the vertical and lateral fire propagation characteristics of exterior wall assemblies that contain combustible components.
It ensures that wall systems limit flame spread both on the exterior surface and within the wall cavity.
Test Overview
- A two-story test apparatus is used with an interior and exterior burner setup.
- The assembly is exposed to fire from an interior room window flame and an exterior burner simulating flames venting out of a window.
- Temperatures and heat flux are monitored at multiple locations within the wall to determine system performance.
- The test runs typically for 30 minutes, assessing both flame spread and temperature rise criteria.
Our Equipment Includes
- Complete NFPA 285 test chamber with structural frame and cladding interface.
- Gas burner system with precise control of flow and pressure.
- Heat flux sensors for calibration and thermocouple networks for accurate data acquisition.
- Data logger system with software for real-time temperature and heat flux monitoring.
- Automatic safety and control panels for reliable and repeatable test cycles.
We Manufacture Complete BS 8414 Test Rigs
At Able Heat Engineering, we design and manufacture complete BS 8414 test setups for evaluating the fire performance of external wall and façade systems.
Our equipment is built in full compliance with BS 8414-1 and BS 8414-2 standards and is used by testing laboratories, certification bodies, and research institutions around the world.
We provide turnkey systems — from structural fabrication to instrumentation and automation — ensuring reliable and repeatable test results.
BS 8414 is the British Standard Test Method for evaluating the fire performance of external cladding systems on multi-story buildings.
It assesses how a complete façade system — including insulation, cladding, subframe, and fixings — reacts to fire exposure from an external source.
This large-scale test is essential for ensuring that building envelope systems limit vertical fire spread and meet safety requirements under realistic full-scale conditions.

ASTM E2307 is the Standard Test Method for Determining Fire Resistance of Perimeter Fire Barrier Systems.
This test evaluates how well a curtain wall and floor joint system resists the spread of fire and hot gases between floors in a multistory building.
In modern high-rise construction, the interface between the curtain wall façade and the floor slab is one of the most vulnerable areas for fire spread.
ASTM E2307 provides a reliable, repeatable method to assess the fire containment performance of this critical joint under realistic building conditions.

Overview
ASTM E84, also known as the “Steiner Tunnel Test”, is the Standard Test Method for Surface Burning Characteristics of Building Materials.
This test evaluates how quickly flame spreads and how much smoke a material produces when exposed to fire.
ASTM E84 is one of the most widely used fire test standards in the construction and building materials industry.
It helps classify materials based on their fire performance.
Purpose of the Test
The purpose of ASTM E84 is to measure two key fire behavior properties:
- Flame Spread Index (FSI) – how rapidly flames move along the surface of a material.
- Smoke Developed Index (SDI) – how much smoke is generated during burning.
These values help determine whether a material can be safely used in interior finishes, insulation, wall panels, ducts, or ceiling systems.
