この概要は現在英語のみで提供しています。
適用範囲
This standard applies to arc flash protective clothing designed to protect personnel from the thermal hazards of momentary arc energy in electrical operations and related workplaces. It is specifically designed for garments protecting the torso and limbs. This standard is mandatory for all manufacturers of electrical safety garments entering the Chinese market. It explicitly excludes insulation protective clothing, electromagnetic protective clothing, and live working shielding clothing. Additionally, it does not cover separate personal protective equipment like arc flash face shields, hoods, gloves, or shoe covers.
技術要求
The standard categorizes fabric arc protection performance into 4 distinct levels, determined by the lower value between the Arc Thermal Performance Value (ATPV) and the Breakopen Threshold Energy (EBT). Manufacturers must clearly indicate this arc rating on the garment. It sets strict flame retardant requirements for both fabrics and linings, evaluating properties like after-flame time, after-glow time, and char length, ensuring no melting or dripping occurs. These properties must be maintained after specified washing procedures. The standard also details comprehensive physical and chemical properties for fabrics, including tensile strength, tear strength, bursting strength for knitted fabrics, and thermal stability. Strict limits are placed on formaldehyde content and pH levels to ensure user safety, alongside colorfastness requirements for washing, rubbing, and perspiration. Structural design and sewing requirements mandate that garments use high-temperature resistant accessories, with metal components not contacting the skin directly. Garment design must allow for quick donning and doffing while completely covering exposed body areas, utilizing styles like jacket, separated, or coverall designs.
試験方法
The standard mandates an arc flash test method (detailed in Annex B) using copper slug calorimeters to measure incident and transmitted heat energy, determining the ATPV and EBT based on the Stoll curve for second-degree burn prediction. It specifies flame retardancy testing according to GB/T 5455, requiring rigorous washing pre-treatments. Additionally, it references standard textile testing methods for evaluating physical and chemical properties, such as tensile strength (GB/T 3923.1), bursting strength (GB/T 7742.1), and colorfastness (GB/T 3920, GB/T 3921). The standard also provides informative calculation methods for arc hazard energy, referencing international practices like IEEE 1584-2018 and NFPA 70E-2018.
よくある質問
What products are regulated under GB 8965.4-2022?
This standard regulates arc flash protective clothing used in electrical operations and related workplaces. It specifically excludes insulation protective clothing, electromagnetic protective clothing, and live working shielding clothing.
How is the arc protection level determined under this standard?
The arc rating is determined by the lower value between the Arc Thermal Performance Value (ATPV) and the Breakopen Threshold Energy (EBT). It categorizes fabrics into 4 distinct levels based on their protective capacity.
Does GB 8965.4-2022 align with international standards like IEC or IEEE?
The standard references international methodologies such as IEEE 1584-2018 and NFPA 70E-2018 for arc hazard energy calculations, and aligns its fabric testing methods with the ASTM F1959 and IEC 61482 series frameworks.
