Plastic materials are tested for flammability according to Australian Standards. While in use, the heater element component of the thermocouple is electrically heated to bright red heat, and plunged into the plastic material in a special test rig. If the material ignites at the reference temperature, then it fails the test.
The standard is proscriptive concerning the design of the thermocouple, and requires the element to be attached to the thermocouple by mechanical clamping and not by welding process. Tests done by non compliant thermocouples will be void, in any dispute.
ECEFast manufacture the 1mm thermocouples in house, and teams with a machine builder to supply compliant construction techniques. ECEFast NATA accredited temperature laboratory issues certificates with each glow-wire thermocouple.
The 1mm thermocouple in type K has an insulated junction, and is manufactured using a semi automatic machine to weld the superfine wires, and close the sheath material.
Other custom designs can be manufactured using this type of high technology equipment to achieve consistent quality, resulting in top performance.
