IEC 60598-1 IPX3/4 Spray Nozzle For Water Ingress Protection Of
Electrical Enclosures Test
Standards compliant:
IEC 60529-2013 “Degrees of protection provided by enclosure (IP
code)” IPX3 and IPX4, Figure 5
IEC 60598-1-2017 “Luminaries-Part1: General requirements and tests”
The spray nozzle is used to verify the protective performance of
the enclosure for electronic and electrical products, automobiles,
motorcycle parts, household appliances, seals and lamps under water
spraying and splashing at degree IPX3 and IPX4. The water pressure
can be adjusted using the flow control handle on the device to give
the required flow rate. The pressure can be seen on the gauge which
is conveniently positioned by the nozzle. A movable shield can be
put down over a portion of the nozzle for IPX3 or moved out of the
spray pattern for IPX4.
Features:
The IPX3/4 spray nozzle is a specialized testing device used to
evaluate the water ingress protection of electrical enclosures,
electronic devices, and other equipment against water spray or
splashing. It is specifically designed to comply with the Ingress
Protection (IP) Code, as defined by the International
Electrotechnical Commission (IEC) standard 60529.
The IPX3/4 spray nozzle is used for testing the water resistance of
equipment against spraying water from various angles. It can
simulate weather conditions where water is sprayed at an angle of
60 degrees (IPX3) or from all directions (IPX4).
Here are some key features and characteristics of the IPX3/4 spray
nozzle:
Nozzle Design: The spray nozzle typically consists of a set of
nozzles or jets arranged in a specific pattern to generate a
controlled water spray. The nozzle design ensures the water is
delivered with the appropriate pressure and angle according to the
IPX3/4 testing requirements.
Water Flow Control: The nozzle may have a valve or flow control
mechanism to adjust the water flow rate, ensuring the specified
water volume is delivered during the test.
Rotational Function: In the case of IPX4 testing, the spray nozzle
may have a rotational function to allow water to be sprayed from
all directions. This is achieved by rotating the nozzle or the test
sample during the test to cover a 360-degree angle.
Water Supply: The spray nozzle is connected to a water supply
system, which can be a controlled water source or a water pump
capable of delivering the required flow rate and pressure.
Compliance with Standards: The IPX3/4 spray nozzle is designed to
comply with the specific requirements outlined in the IEC 60529
standard for ingress protection testing. Compliance ensures that
the testing is conducted according to standardized procedures,
providing reliable and comparable results.
During the IPX3/4 testing, the spray nozzle is positioned at a
specified distance from the equipment being tested. The water is
then sprayed onto the equipment from the defined angles and
durations, simulating real-world conditions such as rain showers or
splashing water. The test evaluates the equipment's ability to
withstand the ingress of water and maintain its protection against
water-related hazards.
It's important to note that the IPX3/4 spray nozzle is just one
component of the overall testing setup for IPX3 and IPX4 testing.
Other equipment, such as a test chamber or enclosure, may be used
in conjunction with the spray nozzle to create the necessary
testing environment and accurately assess the equipment's water
resistance.

Structure:
This device is manufactured according IEC 60529 figure 5, it can
achieve IPX3 / IPX4 hand-held spraying test by connecting water
pipe.
It eEnsure that the water spraying and splashing speed reaches the
standard required value by controlling the water supply flow, make
the enclosure of the specimen to be splashed in all directions.
Normally we suggest to adopt the automatic control for IPX3/4
testing, if client has limit budget, the following easy
installation for IPX3 and IPX4 testing is for reference:
