FCA 7.G2090 Vehicle Interior Components - Formaldehyde Release Test - Acetyl Acetone Method

The standard “FCA 7.G2090 Vehicle interior components - Formaldehyde release test - Acetyl acetone method”, developed by Fiat Chrysler Automobiles (FCA), an Italian-American automotive company, describes test procedures for determining the formaldehyde content in materials such as:

• Textile fiber-based materials treated with phenolic resin and porous sound deadeners
• Textiles, wood fibre-based materials (e.g. masonite) and leather

The equipment used in these tests includes:

• Only type A materials
  • Beaker, capacity 1000 ml
  • Filter paper 12,5 cm ashless 41
• Only type B materials
  • Extraction vessel (glass bottle) with a capacity of 1000 ml screw cap with connection system for tested samples
• generally
  • Acetyl acetone reagent
  • Spectrophotometer UV visible
  • Reagents for formaldehyde test
  • Calibrated bottles
  • Graduated pipettes
  • Test chamber (oven) capable of reaching and maintaining the temperature corresponding to the specified level of intensity, within the specified tolerance at all points, with a maximum relative humidity of 20 percent (the chamber is constructed in such a way that the parts are not exposed to heating by direct radiation from the heating elements anywhere)
  • Thermostatic bath capacity is user-friendly and can maintain 40 degrees plus/minus 2 degrees according to test requirement
  • Precision scales, plus/minus 1 mg
  • Test tubes

Equivalent test equipment may be substituted but must be equal or superior in performance.

The test sample is taken as follows:

• Type A materials: Porous sound deadeners. A minimum of 5 small test pieces are taken from different points to compensate for the uneven distribution of formaldehyde in certain materials in order to obtain a representative sample (approximately 10 g). For preformed materials, test pieces are taken from different compression ratio areas throughout the thickness of the part and also the coatings are removed.
• Type B materials: Textiles / masonite / leather. At least three test pieces, each 40 mm x 100 mm, are prepared from the tested sample. The sampling should be representative of the material under test.

While testing “Type A materials: Porous sound deadeners”,

• The test sample is weighed accurately and placed in a 1000 ml capacity beaker.
• Add 40 ml of distilled water, previously heated to 2 degrees plus/minus 500 degrees, shake well and pour the contents into the test chamber at 1 degrees plus/minus 40 degrees for 2 hour.
• Shake well six times every 1 minutes for a period of 10 hour, then filter the solution using a filter, then allow to cool to ambient temperature for 1 hour.
• 15 ml of filtered solution is taken, placed in a test tube and 5 ml of acetyl-acetone reagent is added, simultaneously preparing the blank solution with 15 ml of distilled water and 5 ml of the same reagent.
• The test tubes, suitably stoppered, are placed in a thermostatically controlled bath at 40 degrees plus/minus 2 degrees for 15 minutes. They are left to cool to ambient temperature in the dark for 1 hour.
• The absorbance is read from the spectrophotometer at a wavelength of 1 nm with a 415 cm optical path cell and a calibration curve is drawn using daily prepared reference standards.
• The formaldehyde concentration (ppm) of the sample is obtained from the calibration curve.

The standard also defines a test method for “Type B materials: Textiles / masonite / leather”.
