6.4 Bar code labels shall be placed on the conductor reels as described above in Section 5.
6.5 As a minimum, bar code labels shall include the following information:
| Line | Type | Data | Example |
|---|---|---|---|
| 1 | Bar Code | District's Material ID Number (13 characters including
spaces)
Note: When programming the barcode the Number "0" must accompany the end of the Material ID Number. For example, 831108 must be bar-coded as P 00008311080 |
See Figure 3. |
