Insulating hot sticks allow lineworkers to safely operate switches, measure voltages, apply temporary grounds, and replace fuses on energized high-voltage lines. Over time, exposure to moisture, dirt, UV radiation, surface tracking, or structural stress can breach the fiberglass shell, posing severe electrical shock hazards.
Burlington Safety Laboratory provides comprehensive, ASTM-compliant dielectric testing and inspection for all fiberglass tools across our state-of-the-art testing facilities in New Jersey and California. With our standard 2-week turnaround time (and expedited services available), we ensure your live line tools remain electrically safe and fully compliant.

Our Step-by-Step Dielectric Testing Process for Hotsticks
Every fiberglass hot stick submitted to Burlington Safety Laboratory undergoes a multi-stage electrical and physical evaluation:
Step 1: Preparatory Cleaning & Decontamination
Hot sticks are thoroughly cleaned using specialized, solvent-free industrial cleaners approved for fiberglass safety tools. This process removes road film, grease, silicone residues, metal particles, and environmental contaminants that create conductive tracking paths on the tool’s surface.
Step 2: Surface Drying
Following cleaning, tools undergo controlled warm-air drying to remove all surface moisture prior to high-voltage dielectric evaluation.
Step 3: High-Voltage Wet/Dry Dielectric Testing
Hot sticks are mounted on specialized test benches and subjected to high-voltage AC dielectric testing in accordance with ASTM F711 standards (typically 100kV per foot for wet/dry dielectric evaluation). Precision sensors monitor current leakage along the length of the tool. Any stick displaying excessive leakage current or internal dielectric breakdown is flagged immediately.
Step 4: Re-Drying Process
After completing electrical tests, tools undergo a final drying cycle to prepare the fiberglass surface for physical and mechanical inspection.
Step 5: Visual Inspection & Structural Integrity Check
Skilled technicians inspect the tool from end-to-end under bright illumination. Technicians verify mechanical operation (latches, springs, head mechanisms) and check for:
- Fiber blooming, surface cracking, deep gouges, or fractures
- UV degradation, delamination, or loss of glossy protective finish
- Damaged, bent, or loose metal operating heads, ferrules, and locking pins
Step 6: Serialized Stamping & Documentation
Hot sticks passing dielectric and visual testing are stamped in durable ink or affixed with weather-resistant labels detailing the unique serial number, test voltage, and test completion date for complete audit traceability.
Step 7: Protective Sleeving & Packaging
Certified hot sticks are wrapped or enclosed in protective plastic sleeving to guard against surface scratches, moisture, and contamination during transport.
Step 8: Boxing & Labeling
Tools are packaged in heavy-duty shipping containers or crates, sealed with Burlington Safety tape, and tagged with detailed tracking information.
Step 9: Shipping or Pickup
Finished orders are shipped via UPS/freight or made available for customer pickup at one of our regional facilities (Burlington, NJ; Pleasanton, CA; Westminster, CA).
Hotstick Field Care & Inspection (In the Field Guidelines)
Proper daily maintenance protects the fiberglass finish and maintains electrical insulation properties between required 2-year laboratory tests:
