FT-F1 fogging tester is professionally designed for the fogging characteristics evaluation of volatile constituents of decorating materials used in cars and aircrafts, e.g. plastic articles, polyurethane, textiles, leather, adhesives, nonwovens and thermal forming elastomers at high temperature conditions. It also could be used for the fogging phenomenon test of high intensity discharge (HID) headlamps of cars.

Principle
The preconditioned specimen is heated and evaporates in the beaker; the volatile constituents condense on the glass plate or aluminum foil treated in cooling chamber. Take off the glass plate or aluminum foil when the condensation process is finished. The fogging characteristics could be obtained by measuring condensed constituent weight and fogging value on the glass plate or aluminum foil and comparing with the data before condensation process.
Three Test Methods
Gloss Method: the specimen is heated in the beaker and its volatile constituents are condensed on the cooling glass plate. The fogging value could be obtained by calculating and comparing the gloss values occurred before and after condensation process.
Haze Method: the specimen is heated in the beaker and its volatile constituents are condensed on the cooling glass plate. The fogging value of the specimen could be obtained by calculating and comparing the fogging values occurred before and after condensation process.
Weighing Method: the specimen is heated in the beaker and its volatile constituents are condensed on the cooling aluminum foil. The fogging value - the weight of condensed constituents could be obtained by analyzing the weight changes of aluminum foil occurred before and after condensation process.
Instrument Structure
The instrument mainly consists of constant high-temperature bath, constant low-temperature bath, cooling plate, beaker, glass plate, meter, sample cutter and other accessories, through which it can perform the processes of sampling, heating, condensation and test.
Operation Process
Prepare specimens-----switch on high and low temperature baths-----clean beakers and glass plates------place specimens----place glass plate or aluminum foil-----place cooling chamber-----perform test for a specified period of time----take off glass plate or aluminum foil and place certain time----measure the gloss value, fogging value of glass plate or weight value of aluminum foil------compare the data and obtain test results
