U.2.2 

Replace this Sub-Clause by: 
Test 8 of IEC 60851-3:1996, 5.1.1, using the 
mandrel diameters of table U.1. The test sample 
is then examined in accordance with IEC 60851-
3:1996, 5.1.1.4, followed by the test of 5.2.2 of 
this standard except applying the test voltage 
between the wire and the mandrel. A test voltage 
shall be the appropriate voltage in table 5B (see 
5.2.2) of this standard. However, the minimum 
values shall be as follows: 

- 

for BASIC INSULATION or 
SUPPLEMENTARY INSULATION, 1500 V, 
or; 

-     for REINFORCED INSULATION, 3000 V.
