Analysis was performed by GC/MS. Result No.1 Note 1. = ppm;0.1wt% = 1000ppm 2. MDL = Method Detection Limit 3. n.d. = Not Detected = less than MDL 4. " - " = Not Regulated 5. ( )The result of Cr(VI) is "n.d." as the result of Chromium (Cr) is less than the MDL of Cr(VI), and confirmation test of Cr(VI) is not required. If the Chromium (Cr) content is not less than the MDL of Cr(VI), confirmation test of Cr(VI) is required. PFOS Reference Information POPs - (EU) 757/2010 Outlawing PFOS as substances or preparations in concentrations above 0.001% (10ppm), in semi-finished products or articles or parts at a level above 0.1%(1000ppm), in textiles or other coated materials above 1µg/m².
