Abstract: An electric wire includes a conductor having a cross-sectional area of not less than 135 mm2 and not more than 165 mm2, an insulation provided so as to cover the outer periphery of the conductor, and a wire sheath provided so as to cover the outer periphery of the insulation. The amount of deflection is not less than 250 mm when, at 23° C., one end of the electric wire is fixed to a fixture table so that another end horizontally protrudes 400 mm from the fixture table and a weight of 2 kg is attached to the other end, and cracks and breaks do not occur when wound with a bending diameter of three times the diameter at −40° C.

Abstract: A quality control method for a diisononyl phthalate includes a measuring step of irradiating the diisononyl phthalate with a laser to measure a Raman spectrum; and an acceptance or rejection decision step of determining an acceptance or a rejection of a quality of the diisononyl phthalate on the basis of a high and low intensity relationship between an intensity of a first spectral peak, which is ascribed to a vibration of molecular chains in a straight chain hydrocarbon, and an intensity of a second spectral peak, which is ascribed to a vibration of isopropyl groups, in the measured Raman spectrum.
