Champ d’application

This standard applies to protective clothing designed to prevent or reduce injuries caused by molten metal splashes in workplaces such as metal smelting and casting. It is mandatory for manufacturers producing protective gear for these hazardous environments. It specifically covers protection against molten aluminum and iron but does not apply to clothing intended for protection against molten cryolite.

Exigences techniques

The standard specifies comprehensive requirements for fabrics (woven, knitted, and leather), including physical and chemical properties such as formaldehyde content, pH value, colorfastness, and tensile strength. Fabrics must not exhibit melting or dripping when exposed to heat. For protective performance, the standard mandates thermal stability at 180°C and strict flame retardancy, including limitations on afterflame and afterglow times. The core requirement involves thermal insulation performance, categorized into levels for radiant heat transfer, molten aluminum splash, molten iron splash, and contact heat transfer. Garments must meet at least one of these insulation levels, including either aluminum or iron splash resistance. Regarding garment design, the clothing must adequately cover the torso, neck, arms, and legs to prevent any exposure during movement. Components like pockets and seams are strictly regulated to prevent the accumulation of molten metal. Accessories such as zippers and buttons must not be easily meltable or flammable, and metal parts must not directly contact the wearer's body.

Méthodes d’essai

Testing methods include standard textile testing for physical and chemical properties. For protective performance, it references ISO 15025:2016 for flame spread and uses specific procedures for radiant and contact heat transfer. The molten metal splash test (detailed in Annex A) involves pouring molten aluminum (at 780°C) or iron (at 1400°C) onto a fabric sample backed by a PVC skin simulant, evaluating the mass of metal required to cause damage. Pre-treatment washing is required for most fabric tests.

Questions fréquentes

What products are regulated under GB 8965.3-2022?

It regulates protective clothing used in metal smelting and casting environments to protect workers from molten metal splashes, specifically focusing on molten aluminum and iron.

Does GB 8965.3-2022 apply to protection against all molten metals?

No, it primarily validates protection using molten aluminum and iron. It explicitly excludes clothing designed for protection against molten cryolite.

How are the thermal insulation performance levels classified?

Thermal insulation is classified into four categories: radiant heat transfer (C1-C4), molten aluminum splash (D1-D3), molten iron splash (E1-E3), and contact heat transfer (F1-F3). Manufacturers must indicate the achieved levels on the product label.
