AbolishedRubber insulationand sheath of electric cables and wires--Part 4:Ordinary duty rubber sheath 65℃
电线电缆橡皮绝缘和橡皮护套 第4部分:65℃一般橡皮护套
Application Summary AI generated
This standard specifies the technical requirements, test methods, and acceptance rules for ordinary duty rubber sheathing used on electric cables and wires, rated for a maximum continuous operating temperature of 65°C. It is applied in the manufacturing and quality inspection of general-purpose power cables, control cables, and flexible cords where moderate mechanical protection and basic environmental resistance are needed. The standard ensures consistent performance in indoor, non-harsh industrial, or light-duty outdoor installations.
