Compliance overview
Scope and applicability
This standard is mandatory for all manufacturers and suppliers of welding protectors in China. It applies to welding face shields, welding goggles, and welding spectacles used to protect against optical radiation, heat particles, and molten metal splashes. It specifically covers protectors with fixed shade number filters, while automatic welding filters are regulated under a separate part (GB 3609.2).
Technical requirements
The standard specifies comprehensive technical requirements for welding protectors. Material and structural integrity must ensure no sharp edges or harmful substances contact the user. Manufacturers must declare that material extraction will not harm the wearer's skin. Optical performance is a critical section, detailing requirements for spherical power, astigmatism, and prismatic power for both plano and corrective lenses. It sets strict limits on luminous transmittance and shade numbers to ensure adequate protection against UV, visible, and IR radiation. Non-optical performance includes requirements for impact resistance, drop resistance, and corrosion resistance. Products claiming high-speed particle impact protection must meet specific grading levels. Additionally, the standard mandates protection against molten metal and hot solids, as well as electrical insulation and flame propagation limits.
Testing methods
Testing methods are detailed in several appendices. Appendix B outlines the methods for measuring transmittance and calculating shade numbers using CIE standard illuminant A. Appendix C describes the drop test procedure, requiring samples to be pre-treated at extreme temperatures (-5°C and 80°C) before falling onto a steel plate. Appendix D covers flame propagation testing, while Appendix E and Appendix F detail electrical insulation and molten metal/hot solid protection tests, respectively.
FAQs
What products are regulated under GB 3609.1-2025?
This standard regulates welding protectors with fixed shade numbers, including welding face shields, welding goggles, and welding spectacles. Automatic welding filters are covered under GB 3609.2.
Are there any updates from the previous version of GB 3609.1?
Yes, the 2025 version replaces GB/T 3609.1-2008. Key updates include the addition of requirements for automatic welding filters terminology, side-view filters, high-speed particle impact protection, and molten metal and hot solid protection performance.
How does GB 3609.1-2025 differ from ISO standards?
While the standard references several ISO standards (such as ISO 16321-1:2021 and ISO 18526-2:2020) in its bibliography, it establishes specific national requirements and testing methodologies tailored to the Chinese market, including particular grading for impact resistance and detailed transmittance calculations.
