Development of European standards that apply to the services offered by hearing aid professionals in their efforts to provide benefit for their clients.
An overview of methods and techniques for determination of the bio-based carbon content of solid, liquid and gaseous products, using the radiocarbon method. This includes sampling, pretreatment, calibration, reporting; determination of terms to be used in field of bio-based products, including horizontal aspects relevant for bio-based product standards; declaration and certification tools applicable to bio-based products.
Determination of perfluorooctanesulfonate (PFOS) in concentrated extracts from coated and impregnated solid articles, liquids and fire extinguishing foams using high performance liquid chromatography-tandem mass spectrometry (LC-tandemMS) or quadrupole mass spectrometry (LC-qMS).
The method is applicable for a concentration range for PFOS in the extract solution of 0,5 µg/l to 50 µg/l.
Elaboration of European standard(s) defining appropriate test methods for the emission evaluation of combustible air fresheners and similar products.

The proposed technical activity should focus its attention on the elaboration of three main European standards for:

• development of standardised test methods for the emissions resulting from the use of combustible air fresheners and similar products
• methodology for the assessment of test results and of acceptable emission limits
• appropriate information on emissions to be supplied by the manufacturer and distributor of combustible air fresheners and similar products to consumers.
