Title 16: Commercial Practices
PART 1505—REQUIREMENTS FOR ELECTRICALLY OPERATED TOYS OR OTHER ELECTRICALLY OPERATED ARTICLES INTENDED FOR USE BY CHILDREN
Subpart A—Regulations


§1505.8   Maximum acceptable material temperatures.

The maximum acceptable material temperatures for electrically operated toys shall be as follows (Classes 105, 130, A, and B are from “Motors and Generators,” Standard MG-1-19671 published by the National Electrical Manufacturers Association):

1Copies may be obtained from: National Electrical Manufacturers Association, 155 East 44th Street, New York, NY 10017.

1If the capacitor has no marked temperature limit, the maximum acceptable temperature will be assumed to be 65 °C. (149 °F.) for an electrolytic type and 90 °C. (194 °F.) for other than an electrolytic type.

2The temperature indicated refers to the hottest spot on the outside surface of the coil measured by the thermocouple method.

3The limitations on rubber- and thermoplastic-insulated wires and cords and on phenolic composition do not apply if the insulation or the phenolic has been investigated and found to have special heat-resistant properties, or if the insulation meets the thermal requirements.

440 less than melting point.

5104 less than melting point.
