As of the beginning of 2018, the OEKO-TEX Association, as usual, has released the testing standards and limit values for the latest edition of the STANDARD 100 by OEKO-TEX product certification, which will be issued after the three-month transition period on April 1, 2018 Officially took effect. OEKO-TEX official representative office in China TESTEX Swiss Textile Testing Co., Ltd. detailed interpretation of the 2018 version of the new rules.
1. New substances added to the 'other residual chemicals' project require more stringent limits
1) More substances are included in the 'Other Residual Chemicals' program for all four product levels *, including:
If one (or more) of these residual chemicals is found to exceed the specified limits during sample testing, the samples will not be certified.
Reasons and implications for the change: Bisphenol A has been included in the ECHA-SVHC Highly Concerned Substances Candidate List and may be found in, for example, plastic materials and mortar prints. Phenol can be absorbed by the body through the skin and has been Class is toxic, corrosive and hazardous to health, and may cause genetic defects, sponges and other materials usually contain phenol.Amine amine aniline by the German Science Foundation (DFG) Advisory Board MAK Group III into four categories with For the detection of hazardous work materials. Among the substances suspected of being carcinogenic (H351) and suspected of causing genetic defects (H341), the European Chemicals Agency (ECHA) has focused on aniline.
2) OPM limits are tightened at all product levels In Exhibit 4, product level I limits are adjusted from 50 mg / kg to 10 mg / kg, and product levels II to IV are limited The value is adjusted from 100 mg / kg to 25 mg / kg In appendix 6, the limit value for all product classes is 10 mg / kg.
3) The limits for SCCPs (also included on the ECHA-SVHC Candidate List) have been reduced to 100 mg / kg for all product levels in Appendix 4, and 50 mg / kg for Annex 6.
4) A new "monitored" substance, quinoline, has not been defined yet, which means that quinoline will be tested randomly for the STANDARD 100 by OEKO-TEX test and the results will be provided to the applicant firm reference.
Reasons for and implications of the change: Quinoline can be used to produce dyes and some other chemical aids that have been classified by the ECHA as CMR substances (carcinogenic, mutagenic or reproductive toxic) and that the CCH substance in the textile The OEKO-TEX Association took active steps to include quinoline in the new standards and used the new concept of 'monitored' as a first step to gather important information To analyze the actual relevance of quinoline in textile materials and accessories.
2. 'Dye' project to increase the decomposition of aromatic amine aniline azo dye detection
In the new standard, in addition to aniline detection in the 'Other Residual Chemicals' project, the aromatic amine anilines cleaved by the azo dyes under reducing conditions will also be tested under the 'Dye' project. At all four product levels (Appendix 4 And Appendix 6), the limit of aniline is 100 mg / kg.
3. Adjust the 'Residual Solvent' item in Appendix 6
In Appendix 6, the product range for N-methyl pyrrolidone (NMP), dimethylacetamide (DMAc) and dimethylformamide (DMF) under the Residual Solvent project is adjusted for the specific limit values so that The standard is more applicable to a wider range of fiber materials under the current technical conditions. The new regulations list three substances for NMP, DMAc and DMF with a limit value of 0.1% for PAN, EL, Aramid and materials coated with polyurethane (PU), polyvinyl chloride (PVC), polyvinyl chloride-glue, polyvinylidene chloride (PVDC), polyvinyl chloride-copolymer, Of the other materials, the limit of 0.05% is still applicable.
4. Add a new substance to the Residual Surfactant Wetting Agent project
Heptaklophenol, Branched and Linear and Pentylphenols, Branched and Straight, New to the Residual Surfactant Wetting Agent Project. The total limit values for alkylphenol and alkylphenol ethoxylates remain unchanged change.
Reasons and Significance for Changes: Heptane, branched and unbranched, and 4-tert-amylphenol (p-1,1'-dimethylpropylphenol) have been included in the ECHA SVHC SVHC Candidate List.
5. Product Level I in the 'water fastness' requirements more stringent
The water fastness requirements in product class I have been raised from the previous '3' to '3-4' grades, so it is expected that the OEKO-TEX certificate will confirm the conformity of the textile products with the Chinese standard GB 18401: 2010 (Except label requirements).
6. Modification of limit values for each of the 'hexavalent chromium' and 'dye' projects in the 'extractable heavy metals' project Description
In order to better compare with RSL lists such as NGOs and retail chains, the new standard requires that the limit values for hexavalent chromium (VI) and various dyes be directly reflected in the table of limit values in Appendices 4 and 6 instead of Annotated as footnotes, this is not a modification of the limited value compared with the previous standard, just to make it easier to understand the changes that have been made to the annotation.
7. Organic cotton products increase the identification of transgenic ingredients
Effective April 1, 2018, OEKO-TEX plans to add GMO testing to organic cotton products in STANDARD 100.
Through these many initiatives, the OEKO-TEX Association strongly supports both the ZDHC and the 'detoxification' and in doing so, OEKO-TEX can greatly enhance the textile supply chain All aspects require the responsible handling of potential hazardous substances in textiles awareness, in order to effectively protect consumers play a pioneering role.
In addition, all STANDARD 100 by OEKO-TEX certifying STANDARD 100 product labels used on certified products and promotional materials, as of January 1, 2018, must be published by OEKO-TEX in October 2016 The latest version. All valid licensees are free to download the two versions (PDF and PNG) in multiple languages via the OEKO-TEX self-service portal. Valid labels in multiple languages are available. For more information on the use of labels, contact OEKO- TEX's official representative office in China TESTEX Swiss Textile Testing Co., Ltd.
Note:
* Product Level:
STANDARD 100 by OEKO-TEX Hazardous material testing standards have always been positioned at the practical level of use of textiles and the tighter the contact with the skin, the more stringent human ecological requirements are met. The standard is divided into four product classes:
Class I: Textiles (clothing, toys, bedding, towels, etc.) for infants and children under 3 years of age.
Level II: direct contact with the skin type of textile (underwear, T-shirts, bedding, etc.).
Level III: No direct contact with skin-type textiles (jackets, jackets, etc.).
Level IV: Decorative materials (carpets, mattresses, etc.).
** Appendix 4: General STANDARD 100 by OEKO-TEX inspection project (substance) and its limit value requirements Based on human ecological considerations, it is tested whether the harmful substances contained in textiles pose a potential hazard to human health and to avoid negative effects on the human body influences.
*** APPENDIX 6: EXTENSION STANDARD 100 by OEKO-TEX Examine the Project (Substance) and its Limits, including but not limited to the Expedition (Substance) in Appendix 4, more than the Expedition (Substance) in Appendix 4 And the more stringent requirements for the limit value.It has been specially developed for companies focusing on detoxification and attaches great importance to the investigation of 'detoxified substances' (the project of * in Appendix 6), so as to enhance the environmental performance of the production process.
