1.2 These requirements cover the electrical isolation properties of the insulation between the isolated circuits of the optical isolator.

1.3 These requirements also cover double protection optical isolators that are employed in circuits rated up to 250 V, 50 or 60 Hz, in radio, video, and television equipment, and similar equipment in applications in which breakdown of the optical isolator may result in a risk of fire, electric shock, or injury to persons.

1.4 These requirements do not cover the electrical properties of the separate circuits of the optical isolator.

1.5 These requirements apply to optical isolators for use as components in devices and appliances. Compliance of an optical isolator with these requirements does not indicate that the isolator is acceptable for use as a component of an end product without further investigation.
