Glow Wire Test Equipment

Specification & Features

• Test apparatus conveniently mounted on control panel
• Glow-wire probe as per standard
• Stainless steel specimen holder
• Thermocouple to set the test temperature
• Temperature controller with constant voltage output with control optimisation
•  Linear drive with defined velocity
• The test equipment is used to investigate the fire-resistant properties of raw materials and finished components
• The glow-wire itself is the source of the fire
• The initial temperature of the glow-wire is set and controlled by a temperature programmer
• During a test, the temperature controller can be switched to manual mode to produce a constant voltage signal to the glow-wire, thus avoiding the sample to a variation in output power, which would otherwise be fed back from the control thermocouple
• The temperature of the glow-wire can be set from room temperature to 1000°C
• The temperature of the glow-wire is detected by a sheathed thermocouple type K (class 1) in accordance with IEC 60584-2
• During the test the specimen is moved towards the glow-wire at a constant velocity of 11 mm/sec and then back again
• The heating time of 30 sec is quartz controlled
• The specimen support is pulled toward the glow-wire with a force of 1 N
