2.10.5.10 Thin sheetmaterial - alternative test procedure
If layers can beseparated for individual testing, the following alternative to the standardtest
procedure in2.10.5.9 is permitted.
Electric strengthtests are applied in accordance with 5.2.2, using test voltages equal to the
test voltagespecified in 5.2.2 for SUPPLEMENTARY INSULATION or REINFORCED INSULATION as
appropriate.
If two layers areused, each layer shall pass the test.
If three or morelayers are used, each combination of two layers together shall pass the test.
If three or morelayers are used, It is permitted to divide these layers into two or threegroups
for testingpurposes. In the above electric strength tests, two or three groups are tested
instead of two orthree layers.
A test on a layer orgroup of layers is not repeated on an identical layer or group.
