FT-F1 Fogging Tester

Description

FT-F1 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. Furthermore it could be used for the fogging phenomenon test of high intensity discharge (HID) headlamps of cars.

Professional Technology

• Wide range and high precision of temperature control device to support the combinations of non-standard test conditions
• 6 test stations can perform specimen test or blank test simultaneously
• FT-F1 fogging tester ensures accurate and reliable test data through stable running condition

Test 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.

This instrument conforms to the multiple international and national standards: ISO 6452, DIN 75201, SAE J1756, QB/T 2728, BS EN 14288, PV 3920, PV 3015, ES-X 83231, NES M0161, D45 1727, GM 9305P, TSM 0503G

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.
