Test criteria

The textiles are tested according to DIN SPEC 4872.

DIN SPEC 4872 is a standardized test method for determining and classifying the environmental impact of textiles during washing. In addition, we check the biodegradability of the fiber abrasion in wastewater (DIN EN ISO 14851) and determine the degree of degradation within a defined period. Finally, an ecotoxicity test (DIN EN ISO 20079:2006-12) is conducted to determine 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
