This test includes three classifications – 94V-0, 94V-1 and 94V-2 – and would typically be acceptable for portable, unattended, intermittent-duty, household-use appliances (i.e., coffee makers). Which classification applies to a particular application depends on many factors, including:
Size and thickness of part.
Distance from uninsulated live parts.
Hot wire ignition.
High current arc ignition.
High voltage arc tracking rate.
This test uses a ?" x 5" specimen which is held at one end in the vertical position (see Fig. 3.1). A burner flame is applied to the free end of the specimen for two 10 second intervals separated by the time it takes for flaming combustion to cease after the first application. Two sets of 5 specimens are tested. The following are recorded for each specimen:
Duration of flaming combustion after the first burner flame application.
Duration of flaming combustion after second burner flame application.
Duration of glowing combustion after second burner flame application.
Whether or not flaming drips ignite cotton placed below specimen.
Whether or not specimen burns up to holding clamp.
