Test Criteria
Textiles are tested according to DIN SPEC 4872.
- DIN SPEC 4872: standardized test method for determining and classifying the environmental impact of textiles during washing
- DIN EN ISO 14851: standardized biodegradability test to check of the fiber abrasion in wastewater - measures the degree of degradation within a defined period
- DIN EN ISO 20079:2006-12: standardized ecotoxicity test - determines the toxicity of the fiber residues after the biodegradation process
Testing Standards
DIN SPEC 4872 was developed based on the following standards:
- DIN EN ISO 14851, Determination of the ultimate aerobic biodegradability of plastic materials in an aqueous medium - Method by measuring the oxygen demand in a closed respirometer
- DIN EN ISO 20079:2006‑12, Water quality - Determination of the toxic effect of water constituents and waste water on duckweed (Lemna minor) - Duckweed growth inhibition test (ISO 20079:2005); German version EN ISO 20079:2006
- ISO 4915, Textiles - Stitch types - Classification and terminology
- ISO 4916, Textiles - Seam types - Classification and terminology
