Lineman's body belt and pole strap systems must meet the following tests:
A dielectric test of 819.7 volts, AC, per centimeter (25,000 volts per foot) for 3 minutes without visible deterioration;
A leakage test of 98.4 volts, AC, per centimeter (3,000 volts per foot) with a leakage current of no more than 1 mA; and
A flammability test in accordance with Table I-7 of this section.
| Test Method | Criteria for Passing Test |
| 1.Vertically suspend a 19.7-inch (500-mm) length of strapping supporting a 220.5-lb (100-kg) weight; | Any flames on the positioning strap must self-extinguish. |
| 2. Use a butane or propane burner with a 3-inch (76-mm) flame; | The positioning strap must continue to support the 220.5-lb (100kg) mass. |
| 3. Direct the flame to an edge of the strapping at a distance of 1 inch (25-mm); | |
| 4. Remove the flame after 5 seconds; and | |
| 5. Wait for any flames on the positioning strap to stop burning. |
