IP Testing Equipment is short for ingress protection testing equipment. They consist of a series of devices used to assess the extent of protection of persons against access to hazardous parts inside the enclosure and protection of the equipment inside the enclosure against ingress of solid foreign objects and (or) against ingress of water.

The IP code indicates the degree of protection provided by an enclosure. Different letters and numerals following the “IP” represent different protection levels. The access probes, object probes, dust chamber and waterproof test equipment, constitute the IP testing equipment. The probes are used to test the protection ability of persons or equipment indicated by the numerals and additional letters in the first and third positions after the “IP”. The dust chamber is suitable for testing the dust-proof ability of the enclosure indicated by the first numeral. The waterproof test equipment is used to test the waterproof performance of the enclosure indicated by the second numeral.

How to choose the right IP Test Chamber for your laboratory?

When selecting an IP waterproof testing system, consider the specific ingress protection level required. For instance, our IPX5/6 Jet Nozzle testers are ideal for simulating heavy seas or powerful water jets, while the IPX7/8 Immersion Tanks are essential for products designed for continuous underwater use. Kingpo’s modular design allows labs to scale from basic drip boxes (IPX1/2) to high-pressure steam jet chambers (IPX9K) within one integrated ecosystem.

What Is the IPX Waterproof Rating Chart?

The IPX Waterproof rating chart summarizes the waterproof protection ability of the casing to its internal equipment under different waterproof grades from IPX1 to IPX9K. The larger the value, the more severe the requirements for the waterproof level. Specific IPX rating descriptions are described in the table below. You can choose the corresponding test items according to the waterproof requirements you want to achieve.

The IPX rating table are as below:

IPX Code	Degree of Protection
IPX0	None
IPX1	Protect the equipment inside the enclosure against vertical water drips
IPX2	Protect the equipment against vertical water drips with the enclosure inclined by 15° in four directions, respectively
IPX3	Protect the equipment inside the enclosure against spraying water
IPX4	Protect the equipment inside the enclosure against splashing water
IPX4K	Protect the equipment inside the enclosure against splashing water with increased pressure
IPX5	Protect the equipment inside the enclosure against water jets
IPX6	Protect the equipment inside the enclosure against strong water jets
IPX6K	Protect the equipment inside the enclosure against strong water jets with increased pressure
IPX7	Protect the equipment inside the enclosure against the effects of temporary immersion in water
IPX8	Protect the equipment inside the enclosure against the effects of continuous immersion in water under conditions agreed upon by the interested parties
IPX9/IPX9K	Protect the equipment inside the enclosure against high pressure and high temperature water jets

Frequently Asked Questions

What is IP testing equipment and what types does KingPo offer?

IP testing equipment, also known as ingress protection test equipment, evaluates a product's resistance to solid objects and water ingress per IEC 60529, ISO 20653, and other standards. KingPo provides a full range including IPX1–IPX2 drip test devices, IPX3/IPX4 oscillating tube and handheld spray nozzles (121 × 0.5mm holes), IPX5/IPX6/IPX6K water jet nozzles (6.3mm and 12.5mm diameters), IPX7/IPX8 immersion tanks, IPX9/IPX9K high-pressure/high-temperature spray chambers (4 fan jet nozzles), dust chambers (IP5X/IP6X), and multi-function combined chambers for efficient lab testing in electronics, automotive, and lighting industries.

What is the IPX9K test and which products require it?

The IPX9K test is the highest-level waterproof rating, exposing products to high-pressure (80–100 bar), high-temperature (80 ± 5°C) water jets at 14–16 L/min using 4 fan-shaped nozzles (per IEC 60529 Figure 7 specs: nozzle radius R0.75 ± 0.01 mm, diameter 3 ± 0.01 mm, etc.). It simulates extreme cleaning conditions like industrial pressure washers. KingPo’s IPX9/IPX9K spray test chamber is ideal for automotive headlights, sensors, connectors, and road vehicle components requiring superior heat and pressure resistance.

What is the difference between IPX7 and IPX8 immersion testing?

IPX7 tests temporary immersion (typically 1m depth for 30 minutes) and suits consumer devices like smartphones and wearables. IPX8 requires continuous immersion at greater depths/times specified by the manufacturer, demanding higher sealing performance. KingPo offers IPX7/IPX8 tanks with electric hoists, thick tempered glass windows (for IPX7), high-pressure sealed vessels (up to 50m equivalent depth for IPX8), PLC touchscreen control, and precise timing for reliable, standards-compliant results.

How to choose the right KingPo IP waterproof testing equipment?
