29 CLEARANCES, CREEPAGE DISTANCES AND SOLID INSULATION
Clearances, creepage distances and solid
insulation withstand electrical stress
P
For coatings used on printed circuits boards to
protect the microenvironment or to provide basic
insulation, annex J applies
N
29.1
Clearances not less than the values specified in
table 16, taking into account the rated impulse
voltage for the overvoltage categories of table 15
P
The values specified may be smaller for basic
insulation and functional insulation if the clearance
meets the impulse voltage test of clause 14
N
Appliances are in overvoltage category II N
Clearances less than specified in table 16 not
allowed for basic insulation of class 0 and class 0I
appliances,

P
29 .1 .1
Clearances of basic insulation withstand the
overvoltages, taking into account the rated impulse
voltage
N
Clearance at the terminals of tubular sheathed
heating eleme nts may be reduced to 1mm if the
microenvironment is pollution degree 1
N
Lacquered conductors of windings assumed to be
bare conductors, but the clearances specified in
table 16 are reduced by 0.5mm for rated impulse
voltages of at least 1500V
N
29 .1 .2
Clearances of supplementary insulation not less
than those specified for basic insulation in table 16
N
29 .1 .3
Clearances of reinforced insulation not less than
those specified for basic insulation in table 16, but
using the next higher step for rated impulse voltage
