The national standard GB20653 protective clothing - occupational high-visibility warning clothing standard refers to the European standard ISO20471:2013 High visibility clothing-Test methods and requirements (high visibility clothing test methods and requirements), but some details will be slightly different. Today, Anbosch will take you to analyze the differences between the national standard and the European standard.
Modified the standard name.
The name of the national standard is "High Visibility Warning Clothing for Occupational Protective Clothing", and the name of the European standard is "High Visibility Clothing". Ambersch believes that the modification of the name makes it clear that high visibility clothing in the Chinese market is mainly used for protection classes and occupations. The main function of this type of clothing is to warn of working hours, for example, when working at night, wearing a type R safety vest or safety jacket can improve visibility and reduce the occurrence of hazards in daily activities.
2. Deleted the "Introduction" of the International Standard.
Added "retroreflective" "non-fluorescent material" to Terms and Definitions and deleted "torso" "long sleeve (1/1 arm)" "road" "active road user" "passive road user" "outer layer" .
5. Modified the design requirements and typical design styles of warning clothing, adjusted the minimum width of the reflective tape of level 1 warning clothing from 50mm to 25mm, and added the requirements for the design of shoulder reflective tape.
6. Added 4.4 "Ergonomic requirements for warning clothing".
7. Modify 5.6 "Comfort moisture resistance and thermal resistance" in ISO20471:2013 to "moisture permeability".
8. Added 5.7 "Chemical Safety Performance Requirements".
9. ISO20471:2013 has a total of 9 chapters, and the national standard has a total of 8 chapters. Chapters 8 and 9 of ISO20471:2013 were amended and merged as Chapter 8 of the national standard "Marking, Maintenance Labels and Instructions for Use".
10. Compared with the 4 appendices (Appendix A to Appendix D) of ISO20471:2013, the national standard has increased to 6 appendices (Appendix A to Appendix F).
11. Modified the legend of warning clothing design in Chapter 4 of ISO20471:2013, and made it an informative appendix A "Typical Design Styles of Warning Clothing".
12. The informative appendix B "Chromaticity Diagram of Base Material and Combined Performance Material" has been added.
13. The normative appendix C "Measurement method of retroreflection coefficient" is added.
14. Adjust Appendix B in ISO20471:2013 as the normative appendix D of the national standard "Arrangement of reflective tapes during industrial washing".
15. Adjust the Appendix C of ISO20471:2013 as the normative Appendix E of the national standard "Measurement method of reflective performance in the rain state".
16. Revise and integrate the relevant content in "Introduction", Appendix A and Appendix D in ISO20471:2013, as the national standard informative Appendix F "Environmental Risk Level and Visibility Clothing Design Guidance", and in Table F. Added an example of a location in 1.
