JIS G3539 is a standard published by the Japanese Standards Association (JSA) that covers steel wires, including wires for general use, wires for springs, and wires for other specific applications. The standard provides specifications for the chemical composition, mechanical properties, and testing methods of steel wires.
The standard, officially titled “Zinc-coated steel wires for armouring of optical fiber cables” , is a critical Japanese Industrial Standard (JIS) that specifies the requirements for galvanized steel wires used to protect optical fiber cables. These wires provide mechanical strength and corrosion resistance, making them essential in telecommunications and underground/underwater cabling systems. jis g3539 pdf
