Performance Tests
Key performance tests which concern over-voltage protection of the secondary
protectors are:
1.
Impulse Voltage Measurement Test -
Secondary protectors must breakdown
within ± 25% of the manufacturers breakdown rating when tested in each
polarity with a rate of voltage rise of 100V/μs, ± 10%. It should be noted 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 the telephone loop.
2.
Breakdown Voltage Measurement Test -
Secondary protectors must breakdown
within ± 25% of the manufacturers breakdown rating when tested in each
polarity with a rate of voltage rise no greater than 2000V/s. The secondary
protector is to be mounted in accordance with the manufacturer
s installation
instructions and then subjected to the test circuit in Figure 4-16. This
requirement only applies to secondary protectors connected between Tip and
Ring or Tip/Ring and ground of the telephone loop.
3.
Over-Voltage Test -
Secondary protectors must limit current and extinguish or
open the telephone loop without loss of its over-voltage protector, indication of
fire risk, or electric shock. Upon completion of this test, samples must comply
with the dielectric voltage-withstand test.
The Over-Voltage Test is used to determine the effects on secondary protectors and is
shown in Table 4-21. Test connections are shown in Figure 4-17.
Test Compliance
Compliance with the Over-Voltage Test is determined by meeting the following criteria:
The cheesecloth indicator may not be either charred or ignited.
The wiring simulator (1.6A Type MDQ fuse or 26 AWG line cord) may not be
interrupted.
The protector will meet the applicable dielectric voltage withstand requirements
after the completion of the over-voltage tests.

Notes:
1. Tests L1, L2, and L5 are to be applied between Tip and ground or Ring and ground.
2. Tests L3 and L4 are applied simultaneously from both Tip and Ring to ground.
