Electrical Properties電器特性 - Performance may be evaluated with respect to electrical track resistance, ability to resist ignition from electrical sources, and other electrical properties. Tests were performed using 60 Hertz unless otherwise specified.

Performance Level Categories-In order to avoid an excessive level of implied precision and bias, material performances for several tests are recorded as Performance Level Categories (PLC), based on the mean test results (rather than recording the exact numerical results), as indicated in the table following the test description.
