適用範囲

This standard applies to protective clothing for welders designed to protect workers against molten metal splashes, flames, and thermal hazards in welding and allied processes. It covers both woven fabric and leather materials used for garments such as jackets, trousers, coveralls, and matching accessories like aprons and spats. It is mandatory for all protective clothing manufacturers targeting the Chinese welding market.

技術要求

The standard classifies welding clothing into two protection levels: Level A (higher protection) and Level B, based on performance capabilities. It specifies stringent physical and chemical requirements for shell fabrics, linings, and accessories. Key parameters include breaking strength, tear strength, and dimensional stability after washing. Manufacturers must ensure that fabrics exhibit no melting or dripping when exposed to heat. For thermal and electrical safety, the standard mandates specific limits for flame resistance, resistance to molten metal droplets, and thermal stability. It also introduces requirements for the radiant heat transfer index (RHTI24) and volume resistance to evaluate insulation and anti-static properties. These requirements apply to both pre- and post-wash conditions for reusable garments. Chemical safety and comfort are heavily emphasized. The standard enforces strict limits on formaldehyde content, pH values, and prohibits the use of decomposable carcinogenic aromatic amines. For leather materials, specific limits for hexavalent chromium and fat content are also regulated. Colorfastness to washing, rubbing, and perspiration must meet minimum grading levels. Structural design and components must prevent hot particles from entering the garment. Accessories like zippers, buttons, and hooks must avoid melting or igniting, requiring thermal stability testing. Metal components must not directly contact the wearer's skin. Seam strength for critical areas like shoulders and crotch is strictly defined to ensure structural integrity.

試験方法

The standard outlines a comprehensive suite of testing procedures to verify compliance. Flame resistance is evaluated using the ISO 15025:2016 (Method A1) test for limited flame spread. Resistance to molten metal impact is assessed by dropping molten metal droplets onto the fabric sample to measure temperature rise. Thermal stability is tested by exposing materials and accessories to a controlled oven environment (e.g., 180°C for fabrics, 260°C for accessories) to check for melting or deformation. Chemical properties such as formaldehyde, pH, and banned azo dyes are tested using standardized textile and leather extraction methods. Additionally, physical properties like breaking and tear strength are measured according to specific GB/T and QB/T standards for woven and leather materials.

よくある質問

What products are regulated under GB 8965.2-2022?

This standard regulates protective clothing for welders (welding apparel), including jackets, trousers, coveralls, and matching accessories like aprons and spats, designed to protect against molten metal splashes and heat hazards.

Are there any significant updates from the previous GB 8965.2-2009 version?

The 2022 revision introduces new requirements for fabric volume resistance, radiant heat transfer index (RHTI), and banned carcinogenic aromatic amines. It also adds specific testing for leather tear strength, hexavalent chromium, and the thermal stability of garment accessories.

How does GB 8965.2-2022 differ from international welding standards like ISO 11611?

The standard incorporates test methodologies from international norms, such as using ISO 15025:2016 for limited flame spread. However, it includes unique Chinese compliance criteria for chemical safety (referencing GB 18401) and specific thermal performance tiers that necessitate localized testing.
