Protective classification for "1st Symbol" solid foreign material
Class Protection Level
0 No protection.
1 Solid foreign material 50 mm or
more in diameter (hand etc.) can-
not come in.
2 Solid foreign material 12.5 mm or
more in diameter (finger etc.) can-
not come in.
3 Solid foreign material 2.5 mm or
more in diameter (wire etc.) can-
not come in.
4 Solid foreign material 1 mm or
more in diameter (wire etc.) can-
not come in.
5 Dust, which interferes a normal
operation of device or spoils the
safety, cannot come in.
6 Any dust cannot come in.
Complies with the 1st and 2nd symbols of IEC60529.
Protective classification for oil penetration.
Note) There are four other classes: “h”, “c”, “d”, and “e”.
Class Protection Level
f Oil retaining type Not affected considerably by oil
drops or oil spray in any direc-
tion.
g Oil resistance type Any oil drop or oil spray in any
direction cannot come in.

Table for conversion from NEMA enclosure into IEC60529. (Conversion from IEC60529 into
NEMA enclosure is unavailable.)
Note: Based on the NEMA Standards. The difference between NEMA enclosure classification and
IEC60529 is anticorrosion, rust prevention, moisture condensation on surface, etc.

Protective classification for "2nd Symbol" water penetration
Class Protection Level Test Method Overview (Test with fresh water)
0 No particular protection Any particular protection
is not taken to water
penetration. No Test.
1 Protection against drop of water Not to be affected by
water dropped vertically. Drop water for 10 minutes using a water drop tester.
2 Protection against drop of water Not to be affected by
water dropped deviat-
ing 15
°
from a vertical
line.
Drop water to an object set inclined 15 ° for 10 minutes (2.5 minutes per
direction) using a water drop tester.
3 Protection against water spray Not to be affected by
water spray deviating
within 60
°
from a vertical
line.
Spray water in an area within 60 ° to the right and left from a verti-
cal line for 10 minutes using a tester shown in this figure.
4 Protection against water splash Not to be affected by
water splash from all the
directions. Spray water from all the directions for 10 minutes using a tester
shown in this figure.
5 Protection against water jet flow Not to be affected by
direct water jet flow from
all the directions. Spray water from all the directions for 1 minute per surface area
1 m
2
, total 3 minutes or more using a tester shown in this figure.
6 Protection against extreme
water jet flow Not to be affected by
extreme direct water jet
flow from all the direc-
tions. Spray water from all the directions for 1 minute per surface area
1 m
2
, total 3 minutes or more using a tester shown in this figure.
7 Protection against water soaking Even if an object is
immersed in water of
specified pressure for a
specified time, any
water penetration must
not be observed. Immerse an object at 1 m deep in water for 30 minutes (assuming
that device height is lower than 850 mm).
8 Protection against water
immersion An object must work
always in water. According to an agreement between a manufacturer and device user.
