This test method is used to determine emissions of organic compounds (TVOC = total volatile organic compounds) which are given off from non-metallic materials in the immediate vicinity of or inside vehicle interiors.
The sum of individual substances according to a gas chromatography analysis and detection with a flame ionization detector (GC/FID) or mass selective detector (GC/MS) is used as a measure of the total emission of a material.
It is preferred to use GC/MS as this technology delivers more accurate and more reliable results. Usage of GC/FID must be agreed by Ford Materials Engineering prior to testing.
The test is performed using Head-Space technique after tempering at 120 °C.
The relevant sampling points, requirements and special provisions relating to the execution of the test can be found in the appropriate specifications and drawings, etc.
If components are made up of a number of different materials, separate tests may be required for each individual material.
