The test method describes the measurement procedure for determining formaldehyde, aldehyde, and ketone emissions from components, parts and materials in the interior of vehicles. The procedure is used for testing the distribution of aldehyde and ketone emissions between components. Subject to certain restrictions, it can also be used for material development and for acceptance testing.



As to its technical content, Part A is for determining formaldehyde content in accordance with the modified bottle method and conforms to VDA 275 (German Automotive Association). Part B is to analyze aldehyde and ketone emissions by high performance liquid chromatography (HPLC).



The bottle method was developed for the purpose of determining the formaldehyde emission from woven textiles and untreated particle boards. It has subsequently been applied in different variants for the testing of other materials.
