Rule 22-B10851 - TELEVISION RECEIVERS
10851.1

The provisions of this section are applicable to television receivers manufactured subsequent to January 15, 1970.

10851.2

Radiation exposure rates produced by a television receiver shall not exceed one half milliroentgens per hour (0.5 mR/hr.) at a distance of five centimeters (5 cm) from any point on the external surface of the receiver, as measured in accordance with this section.

10851.3

Compliance with the exposure rate limit defined in § 10851.2 shall be determined by measurements made with an instrument, the radiation sensitive volume of which shall have a cross section parallel to the external surface of the receiver with an area of ten square centimeters (10 cm2) and no dimension larger than five centimeters (5 cm). Measurements made with instruments having other areas must be corrected for spatial non-uniformity of the radiation field to obtain the exposure rate average over a ten square centimeter (10 cm2) area.

10851.4

All measurements shall be made with the receiver displaying a usable picture and with the power source operated at supply voltages up to the maximum test voltage of the receiver and, as applicable, under the following specific conditions:

(a) On television receivers manufactured subsequent to January 15, 1970, measurements shall be made with all user controls adjusted so as to produce maximum x-radiation emissions from the receiver;
(b) On television receivers manufactured subsequent to June 1, 1970, measurements shall be made with all user controls and all service controls adjusted to combinations which result in the production of maximum x-radiation emissions; and
(c) On television receivers manufactured subsequent to June 1, 1971, measurements shall be made under the conditions described in § 10851.4(b), together with conditions identical to those which result from that component or circuit failure which maximizes x-radiation emissions.
10851.5

The manufacturer shall permanently affix or inscribe a warning label, clearly legible under conditions of service, on all television receivers which could produce radiation exposure rates in excess of the requirements of this section as a result of failure or improper adjustment or improper replacement of a circuit or shield component. The warning label shall include the specification of operating high voltage and an instruction for adjusting the high voltage to the specified value.
