Scope

Scope: This standard specifies the terms and definitions, product models, flame retardant levels and markings, performance requirements, finished cable testing, inspection rules, packaging, transportation, and storage of high-flexible multi-core drag chain control cables. This standard applies to automation production processes where high requirements are placed on wire flexibility at an AC rated voltage of U0/U 300/500V and below, and is used in drag chain applications. Main technical content: I. Flexibility. The product can be bent at 180°C without any change in its external shape, and the minimum bending radius it can achieve. II. Drag chain characteristics. The drag chain resembles a tank chain, composed of numerous interconnected links that can rotate freely between each other. The product is used inside the link joints, moving with the characteristics of the link joints. III. Flame retardancy. Under specified test conditions, when the sample is burned, after the fire source is removed, the flame spread on the sample only occurs within a limited range and self-extinguishes, that is, it has the ability to prevent or delay the occurrence or spread of flames. [GB/T 19666-2005, Definition 3.1] IV. Torsion resistance. Under specified test conditions, the product can twist itself (rotate) within a length of 0.5 meters, with a twist angle of up to 270° without any change in its external shape. V. Tensile strength. Under specified test conditions, the sample is fixed at one end on a bracket, and a load unit is fixed at the other end. Then, the load unit is lifted at a speed of 500mm/min and suspended 20CM for one minute without any damage to the product.
