A known quantity of the sampled filling material according to EN 1883 is manually separated into its elements. Items are collected in separate appropriately marked containers. The contents of each container are weighed to determine the mass of the element of interest and therefore to calculate relative percentages.
The EN 12131 standard specifies test methods for determining the quantitative composition of down and down in a sample. Quantitative composition refers to the percentage of down and down in the sample, which is important for determining the quality of the material.
Below is a summary of the test method for determining the quantitative composition of down and down:
Sample preparation: A representative sample of the material is taken and impurities such as dirt, dust or foreign matter are removed. The sample is then dried to a constant weight at a temperature not exceeding 105°C.
Extraction: The sample is extracted with a solvent that dissolves down but not down. Tetrachloroethylene is often used as a solvent. Extraction is carried out using a Soxhlet apparatus or similar equipment and continues until there is no more extraction.
It is important to note that the EN 12131 standard specifies several other requirements for determining the quantitative composition of down and down, including the use of standardized equipment and procedures, and the need for multiple tests to ensure accuracy and consistency of results.
