The test sample is prepared according to IEC 60851-
5:1997, 4.4.1 (for a twisted pair). The sample is then 
subjected to the test of 5.2.2 of this standard, with a 
test voltage not less than twice 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, 3000 V, or; 

- for REINFORCED INSULATION, 6000 V. 

Not TIW used. 
 

N 

 

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 not be less than twice 
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. 

Not TIW used. 
 

N 

 
The tension to be applied to the wire during winding on 
the mandrel is calculated from the wire diameter to be 
equivalent to 118 Mpa ± 10 % (118 N/mm2 ± 10 %). 

Not TIW used.

Report No.  100711 

 

Replace the first paragraph with the following. 
Test 9 of IEC 60851-6:1996, followed by the electric 
strength 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. 

Not TIW used. 
 

N 

Replace the third paragraph describing the test voltage 
with the following. 
The test voltage shall not be less than 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. 
It is applied between the shot and the conductor. 

Not TIW used. 
 

N 

Replace with the following. 
The test voltage for ROUTINE TESTING shall be the 
appropriate voltage in table 5B (see 5.2.2) of this 
standard. Howeve, the minimum values shall be as 
follows: 
 
- for BASIC INSULATION or SUPPLEMENTARY 
INSULATION, 1500 V r.m.s. or 2100 V peak, or; 
 
- for REINFORCED INSULATION, 3000 V r.m.s. or 
4200 V peak. 

Not TIW used.

Replace with the following. 
Twisted pair samples shall be tested in accordance 
with IEC 60851-5:1996, 4.4.1. The minimum 
breakdown voltage shall not be less than twice the 
appropriate voltage in table 5B (see 5.2.2) of this 
standard. However, the minimum values shallbe as 
follows: 
 
- for BASIC INSULATION or SUPPLEMENTARY 
INSULATION, 3000 V r.m.s. or 4200 V peak, or; 
 
- for REINFORCED INSULATION, 6000 V r.m.s. or 
8400 V peak.
