Performance Tests
The following key performance tests relate to overvoltage protection of the secondary
protectors:
1. Impulse Voltage Measurement Test — Secondary protectors must break down within
2. Breakdown Voltage Measurement Test — Secondary protectors must break down within
3. Overvoltage Test — Secondary protectors must limit current and extinguish or open the
The overvoltage test is used to determine the effects on secondary protectors and is shown
in Table 4.18. Test connections are shown in Figure 4.11.
Test Compliance
Compliance with the overvoltage test is determined by meeting the following criteria:
• Cheesecloth indicator may not be either charred or ignited
• Wiring simulator (1.6 A Type MDQ fuse or 26 AWG line cord) may not be interrupted
• Protector meets the applicable dielectric voltage withstand requirements after the

voltage rise of 100 V/µs, ±10%. Note that the manufacturer may assign separate
breakdown voltage ratings for the Breakdown Voltage Measurement Test. This
requirement only applies to secondary protectors that connect between Tip and Ring of

±25% of the manufacturer’s breakdown rating when tested in each polarity with a rate of
voltage rise no greater than 2000 V/s. The secondary protector is to be mounted in
accordance with the manufacturer’s installation instructions and then subjected to the
test circuit shown in Figure 4.10. This requirement applies only to secondary protectors
connected between Tip and Ring or Tip/Ring and Ground of the telephone loop.
