Color-Coded Incandescent Flange Base T-1 and T-1 3/4 Lamps for Voltage Identification
This document defines the method for voltage identification by the use of color-coded insulators at the base of the lamps. Table 1 shows the design volts and corresponding insulator colors.
The part numbers shown are for example purposes only, as an option.
Insulator colors are to be easily distinguishable as green, yellow, red, and white. Additional colors may be added by a revision process as required.
Rationale: The driving force for the change is to update the document according to industry updates, mostly terminology. The changes would make the document current.
Also, the Committee has decided to take this document from an AS to an ARP.
Also known as: SAE ARP 4156
