Escopo e aplicabilidade

This standard applies to static protective clothing designed for workplaces where electrostatic discharge may cause electric shock, fire, or explosion hazards. It is mandatory for manufacturers producing woven and knitted anti-static workwear for the Chinese market. The standard explicitly excludes non-woven anti-static garments and clothing designed for protection against power voltage.

Requisitos técnicos

The standard outlines comprehensive physical and chemical requirements for both woven fabrics and knitted fabrics. For materials, it mandates strict limits on formaldehyde content, pH value, and prohibits the use of decomposable carcinogenic aromatic amines. Garments must also be free of any unpleasant odors. Regarding structural integrity, the standard specifies requirements for breaking strength, tear strength, and seam strength to ensure durability during physical labor. Colorfastness is heavily regulated across multiple dimensions, including washing, rubbing, light exposure, and perspiration. Dimensional stability after washing is also strictly controlled to maintain garment fit. For anti-static performance, the standard dictates the spacing of conductive fibers and sets limits for the point-to-point resistance and the total charge quantity per garment. Garments designed with grounding functions must meet specific resistance limits between test points and the groundable point.

Métodos de ensaio

Testing procedures include evaluating point-to-point resistance using specialized electrodes and an insulation platform, as detailed in the normative appendices. The charge quantity is measured using a rotary drum friction machine and a Faraday cage. Garments must undergo rigorous washing procedures prior to electrical testing to simulate real-world usage. Physical properties such as bursting strength and pilling are tested according to referenced GB/T standards.

Perguntas frequentes

What products are regulated under GB 12014-2019?

The standard regulates static protective clothing used in environments where static electricity may cause electric shock, fire, or explosion hazards. It does not apply to non-woven static protective clothing or garments designed for anti-power supply voltage.

Are there any updates from the previous version of GB 12014?

The 2019 version integrates the content of GB/T 23464-2009 for knitted garments. It added requirements for fabric tear strength, decomposable carcinogenic aromatic amines, and odor. The previous grading system for static protective clothing was also canceled.

How does GB 12014-2019 differ from ISO or IEC standards?

GB 12014-2019 references international guidelines such as IEC/TS 60079-32-1 and IEC 61340-4-9 but establishes its own specific testing parameters, including a strict charge quantity limit and defined washing procedures for domestic compliance. Manufacturers must test according to the GB-specified appendices rather than relying solely on ISO test data.
