Methods for the determination of fogging characteristics
1. Photometric method
Method A (photometric method) quantifies fogging by measuring the specular gloss to determine the change in the 60º reflective index before and after the test sample is placed in a beaker sealed with a piece of cooled glass and the bottom of the beaker is placed in a controlled temperature oil bath for a specified period of time.
2. Gravimetric method
Method B (gravimetric method) calculates fogging by using a disk of aluminium foil instead of the piece of glass to seal the beaker with the test sample inside. The disk is weighed before and after the test to determine the change in weight.
The controlled heating unit has different holes to hold the beakers with the test sample inside.
The determination of fogging characteristics is performed in accordance with the following standards:
√ ISO 6452. Rubber- or plastics-coated fabrics - Determination of fogging characteristics of trim materials in the interior of automobiles.
√ DIN 75201. Determination of the fogging characteristics of trim materials in the interior of automobiles.
√ SAE J1756. Determination of the Fogging Characteristics of Interior Automotive Materials.
√ PV 3015. Non-Metallic Materials for Interior Trim – Determining Condensable Constituents (Gravimetric method).
√ PV 3920. Non-Metallic Materials for Interior Trim – Determining Condensable Constituents (Photometric method).
√ STD 420-003. Fogging. Organic materials.
√ GMW 3235. Fogging Characteristics of Trim Materials.
√ VCS 1027. 2719 Fogging.
√ D45 1727. Interior trim materials and cockpit parts fogging – misting.
Heating bath: +40 to +130 °C
Cooling bath: +20 to +80 °C
For using of the gravimetric method you need a 5 decimal balance (ask us for a suitable option) and aluminium foil discs (EB 03.09).
We can offer a gloss meter (HACS-380) and a haze meter (HATH-100) for determination of fogging value.
Application Scenarios for Fogging Test
Automotive interior materials testing
Automotive interior materials such as instrument panels, knobs, seat cushions, floor leather, plastic particles, carpets, leather, adhesive products, roof materials, etc. to carry out high-temperature volatile fogging test test.
Front xenon lamp test
Used to determine the fogging phenomenon of front xenon lamp under high temperature conditions.
Volatile organic substances test
For automotive interior materials in the volatile organic substances, such as PVC, textiles, leather, nonwovens, rubber and plastic products and other materials at high temperatures in the volatile components of the fogging performance evaluation.
How the Fogging Test Works
The basic principle of the fogging tester is that the sample is heated to volatilise it, the volatile gases condense on a glass plate or aluminium foil cooled in a cooling chamber, and the fogging performance of the sample is then assessed by measuring the weight or properties of the condensate.
Specifically, the sample is heated in a fogging cup and begins to evaporate. The evolved gases condense on a cooled glass plate or aluminium foil. At the end of the condensation process, the glass plate or aluminium foil is removed and the atomised volatilisation properties of the sample are derived by measuring the weight of the condensed components and comparing it with the data before condensation. This method can be used to assess the fogging properties of materials and is particularly important in the application of automotive interior materials.
There are also nebulisation testers which simulate the flow of air by connecting to a breathing simulator, collecting the aerosol particles emitted and determining the amount of nebulisation by analysing the mass of the test substance collected. The mass of the test substance divided by time gives the spray rate, which in turn gives the aerosol particle output. This method is primarily used to test respirator filters or other devices where precise control of atomisation is required.
Operational Details of the Fogging Test
Prepare specimens: Prepare specimens of appropriate size and quantity according to test requirements.
Adjust temperature: Open the high and low temperature baths and set them to the required temperature.
Wash the apparatus: Clean the nebuliser cup and the nebuliser glass plate to ensure that no contaminants interfere with the test results.
Place the sample: Place the sample in the nebuliser cup and press down using the pressure ring.
Place the cooling chamber: Place the cooling chamber and glass or aluminium foil in position.
Start the test: Maintain both baths at the set temperature and operate normally for the required test time. Then remove the glass or aluminium foil and leave for the required measurement time.
Record data: Measure the gloss, haze or weight of the glass or aluminium foil and record the data.
Comparative analysis: The measured results are compared with the pre-condensation data to calculate the atomisation performance of the sample.
Precautions for the Fogging Test
The following points should be observed when carrying out the fogging test.
Environmental control
Ensure that the temperature and humidity of the test environment are within the specified range so as not to affect the test results.
Instrument calibration
Calibrate the instrument regularly to ensure the accuracy of the test results.
Operational standardisation
Strictly follow operating procedures to avoid data deviation caused by operating errors.
Safety protection
Observe safety precautions during testing to avoid high temperature, high pressure and other potential hazards.
Maintenance of Fogging Test
Power supply and grounding: The power supply should be in accordance with the requirements of the product nameplate, to ensure good grounding, to avoid sharing the power cord with high power equipment, and to avoid the use of heavy vibration and strong electromagnetic interference in the environment.
Temperature control: The temperature of the heat-carrying oil in the main unit can only be heated up to 150℃, and it is strictly prohibited to exceed this temperature. The ambient temperature of the room where the unit is located should be at least above 0℃, and it cannot be used in the working environment where the temperature exceeds 30℃.
Cleaning and disinfection: Remove the mask, mouthpiece and medication cup from the nebuliser, rinse or soak in clean water for 15 minutes, then air dry. For sterilisation, immerse the accessories in 75% medical alcohol, soak for the specified time and then rinse well.
Storage and care: The nebuliser should be stored in a cool, dry, well-ventilated room, avoiding storage upside down or horizontally and without the use of lubricants, grease, etc.
Replace filters: If the filters become discoloured, replace them immediately with new ones, making sure they are clean and dry to avoid clogging.
Avoid excessive vibration: Avoid strong vibrations and shocks during use and storage so as not to affect the nebulising effect and the life of the device.
