_____________
INTRODUCTION TO AMENDMENT 2
This Amendment 2 introduces a new degree of protection IP X9 whereas no modifications of
the existing degrees of protection are made.
Thus neither additional tests nor modifications of the existing certificates should be requested
in case of enclosures providing a different IP code.
CONTENTS
Add the following new subclause title:
14.2.9 Test for second characteristic numeral 9 with a spray nozzle

4.1 Arrangement of the IP Code
Replace the sixth line by the following:
(numerals 0 to 9, or letter X)

4.2 Elements of the IP Code and their meanings
Add, in the line “Second characteristic numeral”:
9 High pressure and
temperature water jet
4.3 Examples for the use of letters in the IP Code
Replace the last line by the following:
IPX5/IPX7/IPX9 – giving three degrees of protection by an enclosure against water jets,
temporary immersion and high pressure and temperature water jet for a
“versatile” application.
6 Degrees of protection against ingress of water indicated by the second
characteristic numeral
Replace the second paragraph by the following:
The tests for the second characteristic numeral are carried out with fresh water. The actual
protection may not be satisfactory if cleaning operations with high pressure and temperature
water jet outside the requirements of second characteristic numeral 9 and/or solvents are
used.
– 4 – 60529 Amend. 2 © IEC:2013
Replace the seventh paragraph by the following
An enclosure designated with second characteristic numeral 7 or 8 only is considered
unsuitable for exposure to water jets (designated by second characteristic numeral 5 or 6) and
need not comply with requirements for numeral 5 or 6 unless it is multiple coded. An
enclosure designated with second characteristic numeral 9 only is considered unsuitable for
exposure to water jets (designated by second characteristic numeral 5 or 6) and immersion in
water (designated by second characteristic numeral 7 or 8) and need not comply with
requirements for numeral 5, 6, 7 or 8 unless it is multiple coded as follows:
Replace the table after the seventh paragraph by:

Replace the last paragraph before Table 3 by the following:
Enclosures for “restricted” application indicated in the last column are considered suitable
only for the conditions to which they were tested.

Add, at the end of Table 3, the following new line:
9 Protected against high pressure Water projected at high pressure 14.2.9

Or
1 min/m 14.2.9 b)
Test of large enclosures as per intended use
at least 3 min
Spray from all practical directions
Distance (175 ± 25) mm
14.2 Test conditions
Replace the second paragraph by the following:
Details concerning compliance of degrees of protection – in particular for second
characteristic numerals 5/6/9 (water jets) and numerals 7/8 (immersion) – are given in

Replace the last sentence of the fourth paragraph by:
For IPX7 and IPX9 details of the water temperature are given in 14.2.7 and 14.2.9
respectively.
Add the following new subclause:
14.2.9 Test for second characteristic numeral 9 by high pressure and temperature
water jetting
The test is made by spraying the enclosure with a stream of water from a standard test nozzle
as shown in Figures 7, 8 and 9.
The set-up for measuring the impact force of the water jet is given in Figure 10.
The distribution force shall be verified at upper and lower limits of distance tolerance range
(see Figure 11).
During the test a) or b) of the enclosure, the water temperature shall be (80 ± 5) °C.
a) For small enclosures (largest dimension less than 250 mm), the enclosure shall be
mounted on the test device shown in Figure 12.
– turntable speed: 5 r/min ± 1 r/min
– spray positions: 0°, 30°, 60°, 90°
The test duration is 30 s per position.
b) For large enclosures (largest dimension greater than or equal to 250 mm), the enclosure
shall be mounted as per intended use. The entire exposed surface area of the enclosure
shall be subjected to the spray at some point during the test procedure.

– 6 – 60529 Amend. 2 © IEC:2013
– spray positions: the enclosure shall be sprayed from all practical directions covering
the entire surface area and the spray shall be, as far as possible, perpendicular to the
sprayed surface.
– distance between nozzle and sample under test shall be 175 ± 25 mm.
The test duration is 1 min/m of the calculated surface area of the enclosure (excluding any
mounting surface), with a minimum duration of 3 min.

14.3 Acceptance conditions
Replace the first paragraph by the following:
After testing in accordance with the appropriate requirements of 14.2.1 to 14.2.9, the
enclosure shall be inspected for ingress of water.

Add, after Figure 6, the following new figures:
