The 60-degree Bunsen Burner test is used to determine the resistance of cable & electric wire insulation to a flame applied for 30-seconds.
A test sample is aligned at 60° and exposed to a small Bunsen burner flame. The flame is applied for 30 seconds and then pulled away from the sample. If the sample continues to flame, this flame time is recorded along with any flaming drips that may occur. After the test is over, the burn length is measured. The pass/fail criteria is based on these three values averaged across three test samples.
This test is typically used to show compliance with the following Federal Aviation Regulations (FARs):
