Assessment on Thermal Sensitivity of Fusable Links With a Wind Tunnel

This is a paper on exploring how codes on assessing thermal sensitivity of fusable links for controlling fire shutters can be established. Typical samples of fusable links were tested in a wind tunnel for studying the thermal response of sprinkler heads. In the test, the fusable link samples were loaded under 0.4 kgf. The working section of the tunnel was set at air temperature of 135°C and air speed of 2.54 ms⁻¹. Results suggested that it is feasible to assess the thermal sensitivity of fusable links by following international testing standards.
