Quick Answer
Quick Answer: What Is IP Testing Equipment?
IP Testing Equipment verifies how an enclosure protects people from hazardous parts and protects equipment from solid foreign objects, dust and water ingress.
The required apparatus follows the claimed IP code: access probes and dust chambers address the first numeral, while drip, spray, jet and immersion systems address the second numeral.
IEC 60529 is the general enclosure standard. ISO 20653:2023 applies specifically to electrical equipment in road vehicles and includes automotive-oriented code variants and test conditions.

Which Standard Applies to Your IP Test?
Do not select equipment from the IP number alone. First freeze the governing publication, product standard, target code and test conditions; similar code labels can have different apparatus or procedures.

How to Select IP Testing Equipment
A complete laboratory usually separates solid-ingress equipment from water systems to prevent contamination. Choose the modules needed for the target code rather than assuming that one chamber performs every test.
Access and Object Probes
Test spheres, jointed fingers, rods and wires evaluate access to hazardous parts and entry of solid foreign objects.
- IP1X sphere and access probe
- IP2X jointed finger or sphere
- IP3X rod and IP4X wire
IP5X / IP6X Dust Chambers
Controlled dust circulation, optional specimen vacuum and chamber monitoring support dust-protected and dust-tight enclosure tests.
- Specimen volume and load
- Dust circulation and recovery
- Vacuum and energized-DUT options
IPX1 / IPX2 Drip Systems
Drip boxes simulate vertically falling drops and inclined-enclosure exposure with controlled water delivery and specimen positioning.
- Drip area and needle spacing
- Turntable size and inclination
- Flow verification and drainage
IPX3 / IPX4 Spray Systems
Oscillating tubes or handheld spray nozzles test spraying and splashing water according to DUT size and access constraints.

- Nozzle geometry and shield
- Pressure, flow and distance
IPX5 / IPX6 Water Jets
Calibrated jet nozzles and controlled flow systems evaluate resistance to water jets and powerful water jets.
- Nozzle and flow selection

- Open or enclosed configuration
IPX7 / IPX8 Immersion
Immersion tanks and pressurized vessels address temporary or continuous immersion under the conditions defined by the applicable standard or agreement.

IPX9 / IPX9K Hot-Water Jets
High-pressure, high-temperature spray systems use controlled fan jets, specimen rotation and defined angular positions.
- IEC 60529 or ISO 20653 basis

- Impact-force and nozzle verification
Combined Waterproof Platforms
Integrated platforms can share water treatment, controls and specimen handling while retaining the correct apparatus for each IPX method.
- Required IPX modules
- Water filtration and recovery
- Automation and recipe control
Automotive Splash and Rain Tests
ISO 20653, ISO 16750-4, JIS D 0203 and customer methods may require dedicated spray, splash or thermal-shock arrangements.
- Vehicle-component application
- Hot/cold fluid conditioning
- Fixture and operating-mode control

IP Testing Equipment FAQ
What does an IP rating measure?
It classifies protection provided by an enclosure. The first numeral addresses access and solid foreign objects, including dust; the second numeral addresses water ingress. Additional letters may convey other defined information.
Is IEC 60529 the same as ISO 20653?
No. IEC 60529 is the general IP-code standard for electrical enclosures within its scope. ISO 20653:2023 applies to enclosures of electrical equipment in road vehicles and includes automotive-specific requirements and code variants.
Can one chamber perform every IP test?
Usually not. Dust and water equipment should generally remain separate to control contamination. Multiple water modules can share utilities and controls, but each method still needs the specified apparatus and test conditions.
What is the difference between IPX7 and IPX8?
IPX7 addresses temporary immersion under defined conditions. IPX8 addresses continuous immersion under conditions specified by the applicable standard or agreed between relevant parties. The required tank or pressure vessel must match those conditions.
Does IPX8 automatically include IPX6?
Do not assume so. Jet and immersion tests represent different exposures. Required claims and combinations depend on the governing standard, product standard and certification plan.
What is required for IPX9 or IPX9K testing?
A compliant hot-water high-pressure spray system, verified fan-jet nozzles, controlled angles and distance, specimen rotation or positioning, and calibrated temperature, pressure and flow measurement. Confirm whether IEC 60529 or ISO 20653 governs the project.
How should a laboratory size the chamber?
Provide the DUT envelope, mass, mounting orientation, required nozzle distance or tube radius, cable routing and operator access. Allow space for water management, maintenance and safe specimen handling.
What should I send for an accurate quotation?
Send the standard and edition, target IP code, clauses, DUT drawing and mass, test orientation, operating-state requirements, available utilities, laboratory dimensions and calibration or reporting expectations.
