The various factors affecting static generation in carpets such as relative humidity, fiber type, shoe-sole material, carpet backing, and treadwear have been examined in this paper. Experiments to determine threshold level of static sensitivity in humans have been made. Critical evaluations of current carpet static test methods have been made, and the use of low voltage (discharge voltage) instead of maximum voltage value is suggested. A new carpet static test method using a motorized treadmill device has been described.
