3.4.4.2 Left regular lay. Wires in the strand are laid to the right, and strands in the rope are laid to the left.
3.4.4.3 Right lang lay. Both the wires in the strand and the strands in the rope are laid to the right.
3.4.4.4 Left lang lay. Both the wires in the strand and the strands in the rope are laid to the left.
3.4.4.5 Rope lay length. Rope lay strength shall not be less than 5 1/2 times the nominal rope diameter. The maximum rope lay length shall be not more than specified in the applicable table or ASTM A1023/A1023M.
3.5 Construction. Unless otherwise specified (see 6.2(j)), the contractor may supply wire rope and strand of any construction applicable to the size rope or strand being furnished.
3.6 Lubrication.
3.6.1 Iron or traction steel wire rope for elevator service. Wires of iron or traction steel wire rope for elevator service shall be thoroughly coated with lubricant during the process of manufacture. The lubrication shall be compounded for each specific application so as not to restrict the rope's operating characteristics.
3.6.2 Uncoated iron or steel wire ropes. Unless otherwise specified, wires of uncoated (not galvanized) iron or steel wire ropes shall be thoroughly coated with a lubricant during the process of manufacture. The lubricant shall provide lubrication qualities and corrosion protection during shipping, storage, handling and the initial period of service; provide a suitable lubricant base for subsequent field re-lubrications; and be free of substances injurious to steel wires and fiber cores.
3.6.2.1 When specified (see 6.2(k)), a heavy corrosion inhibitor shall be applied to the entire length of the wire rope after closure to prevent corrosion prior to installation.
3.6.3 Coated (galvanized) steel and iron, corrosion-resistant steel, and phosphor bronze wire ropes. Unless otherwise specified (see 6.2(l)), coated (galvanized) steel and iron, corrosion- resistant steel, and phosphor bronze wire ropes may be lightly lubricated during fabrication.
3.6.4 Fiber centers and cores. Fiber centers and cores shall be thoroughly impregnated during fabrication with a lubricant which shall contain preservative materials to allay deterioration of fiber parts due to rot or mildew and shall not be injurious to the steel wires. This requirement is not applicable to synthetic cores or centers.
3.6.5 Wire strand core and IWRC. Wire strand core and IWRC shall be thoroughly covered with a lubricant for protecting and preserving their wires.
3.7 Diameter of wire rope and strands. Except for type II elevator, type III spring lay, type IV
marline clad, type V seizing strand, and type VI small cord, which are of special construction,
