Chemical Analysis
Technical specification governs the laboratory extraction of perfluorinated compounds from coated fabrics and impregnated materials. Adhering to din cen/ts 15968 involves a specific pressurized liquid extraction or ultrasonic method to ensure all restricted substances are recovered. This document provides the framework for testing compliance with environmental regulations regarding persistent organic pollutants.
Detailed solvent requirements ensure that the laboratory results are comparable across different international testing facilities.
Analytical Precision
Quantitative measurement relies on liquid chromatography coupled with mass spectrometry to identify individual molecules. Following din cen/ts 15968 allows technicians to separate pfos from complex mixtures of finishing oils and polymers. Calibrated standards are essential for calculating the exact concentration of the extractable chemicals.
Certification Compliance
Verification of textile goods for the european market often requires data generated according to this technical specification. Because din cen/ts 15968 covers a wide range of solid articles, it applies to zippers, buttons, linings and threads. Compliance reports must state the extraction temperature and the solvent used during the procedure.
Specimen Depth
Sampling of multi-layered materials requires the separation of the coating from the substrate when possible. If the coating cannot be isolated, din cen/ts 15968 mandates that the entire composite be ground and extracted as a single unit. Solvent volume must be sufficient to fully submerge the shredded specimen throughout the extraction cycle.
