Testing of Fibreglass Rod to 5000v and 10000v

We are seeking a certified laboratory to conduct high voltage insulation testing on fiberglass rods, which are used as non-conductive road forming and fencing pins. The rods need to be tested at 5,000 volts and 10,000 volts to verify their dielectric strength and non-conductivity. Upon completion, a formal test report or certificate confirming compliance with the specified voltage ratings is required.
