SABS Tested Standards

E90 Transparent Fire Rated Screens

Test Procedure

FSA's E90 transparent fire rated screen was tested to the Fire Resistance Standard; SANS 10177 – Part 2: 2005. Our screen was tested as a non-load bearing & complete assembled unit for 90 minutes, and passed uncontested.

The test was conducted in a large-scale air-aspirated diesel-driven furnace. The furnace temperature is controlled to follow the ISO standard time-temperature curve as stipulated in SANS 10177 – Part 2. The Fire Resistance Rating (FRR) of the system is determined based on the following criteria:

    •  Stability (R):

            •    Loadbearing:

                  The system is considered to fail structurally should the primary stud (structural element) temperature reach 375 oC of a light weight steel system

                  or the deflection is beyond the Neutral Axis (Deflection measured from unexposed side is more than 50% of the wall thickness).

            •    Non-loadbearing:

                  The test specimen should remain intact inside the test frame for the full duration of the test as a self-supporting structure.

    •  Integrity (E):

                  The system is deemed to have failed should flames be observed on the unexposed side or an opening larger than 6mm wide or 150mm long is noted.

    •  *Insulation (I):

                  The temperature on the unexposed surface may not exceed 140 oC plus ambient temperature on average, or 180 oC plus ambient maximum at any of the

                  measured surface positions.

                  * No temperatures was measured – Test did not included insulation as a criteria.

Test Equipment

The following test equipment were used:

     •    Data logging equipment c/w controller

     •    Stopwatch

     •    Type K thermocouples

     •    SANS 10177 – Part 2 Vertical Test Facility

Test Temperature – Measured in degree Celsius (oC)

The test specimen was tested at a temperature of 1015 oC – See photo / graph below.

FIRELAB Conclusion: FSA Pass

SANS 10177 – 2    :    F90: Non-load bearing

              Stability    :    90 Minutes

             Integrity    :    90 Minutes

          Insulation    :    N/A – Not tested

The FSA Transparent Fire Rated Screen is suitable for internal & external glazing in buildings provided safety distances and other fire safety requirements with regard to occupancy, division & tenancy separating elements in terms of the National Building Regulations, SANS 10400 – Part T (Fire Safety) are met.
