Fatal mistakes in IPX9K waterproof test: nozzle size and water temperature control, the truth you must know
In today's era of pursuing high quality and high standards, IPX9K waterproof testing has become a key link in the production of electrical and electronic equipment. However, there are some extremely bad phenomena in the industry - some companies, in order to reduce costs and seek temporary convenience, actually use nozzles that do not meet the requirements of the IEC 60529 standard for testing. This behavior is not only a blasphemy to their own profession, but also a great disrespect for product quality and consumer rights. It is simply playing with the safety and reliability of the product! This behavior must be severely condemned, and such chaos in the industry needs to be rectified urgently!
1. Size requirements for IPX9K nozzles
According to the IEC 60529 standard, the size and design of the IPX9K waterproof test nozzle have strict specifications, which ensure the accuracy and reliability of the test. The following are the key size requirements:
1. Nozzle diameter
• Standard requirements: The nozzle diameter must meet the standard drawing requirements, which is the key parameter to ensure that the flow rate and pressure of the water flow meet the test requirements.
• Calibration requirements: The dimensions of all printheads must be calibrated by a third party to ensure that they meet standard requirements.
2. Nozzle size details
According to Figure 7–Fan jet nozzle dimension and Figure 8–Fan jet nozzle resulting dimensions of spraying hole for checking purpose in the IEC 60529 standard, the specific size requirements of the nozzle are as follows:
• Nozzle radius:
• R0.75±0.01 mm
• R1.5±0.005 mm
• Other nozzle sizes:
• 8±0.01 mm
• 9.69±0.01 mm
• Nozzle diameter:
• 3±0.01 mm
• 2.34±0.06 mm
• Total nozzle length:
• 13.33±0.04 mm
The deviation of each size may lead to a huge difference in the test results, thus affecting the accurate evaluation of the product's waterproof performance. Those companies that use unqualified nozzles completely disregard the accuracy and reliability of the test results. This behavior is a great harm to the entire industry and a naked infringement of consumer rights.
3. Nozzle surface quality
According to Figure 9 in the IEC 60529 standard – Example of different quality achievements of the surface finish of the fan jet nozzle, the surface quality requirements of the nozzle are as follows:

Good surface finish
Industry often misuses:
KINGPO complies with standard sprinkler heads:
• Smooth surface: The nozzle mouth needs to be smooth and free of burrs.
• Material: The nozzle should be made of high-quality stainless steel to ensure its durability under high temperature and pressure conditions.
The smoothness of the nozzle surface and the choice of material also have an important impact on the test results. A smooth surface without burrs can ensure the uniform spraying of water, while high-quality stainless steel materials can ensure that the nozzle maintains stable performance in long-term high-temperature and high-pressure use without deformation or damage, which will affect the accuracy of the test. Those companies that use unqualified nozzles completely ignore these details. This behavior is extremely irresponsible for product quality and extremely disrespectful of consumer rights.
4. Nozzle angle and flow rate
• Spray Angle: The spray head is designed to achieve spray angles of 0°, 30°, 60° and 90° to ensure full range of testing of the equipment .
• Flow and pressure:
• Flow rate: The water flow rate needs to be controlled at 14-16 liters/minute.
• Pressure: The water pressure of the nozzle needs to reach 8-10 MPa (80-100 bar).
The precise control of the spray angle and flow pressure simulates the impact of water on the equipment in different use environments. Only by meeting these standards can we truly reflect the waterproof challenges that the product may encounter in actual applications, thereby effectively testing the waterproof performance of the product. Those companies that use unqualified nozzles completely disregard these standards. This behavior is a great disrespect for the test results and a great irresponsibility for product quality.
2. Water temperature requirements for IPX9K test
According to the IEC 60529 standard, the water temperature requirements for the IPX9K test are as follows:
• Water temperature range: The temperature of the test water should be maintained at 80±5℃.
• Temperature stability: During the test, the water temperature should remain stable to ensure consistent test conditions.
The control of water temperature is also crucial to the test results. High-temperature water flow can simulate the use of equipment in extreme environments, such as the engine compartment waterproof performance test of a car driving in hot and rainy weather, or the reliability test of outdoor electronic equipment in a hot water splash environment. If the water temperature is not properly controlled and cannot reach or stabilize within the range required by the standard, the test results will not reflect the actual situation that the product may encounter in actual application, which will make the test meaningless and may even lead to misleading judgments on the long-term stability and reliability of the product.
3. Current status and hazards of industry misuse
Although the IEC 60529 standard has clear provisions on the size and water temperature requirements of IPX9K nozzles, in the industry, some companies, in order to save costs and pursue efficiency, actually use nozzles that do not meet the standard requirements, or are perfunctory in water temperature control. This behavior must be given enough attention and condemned.
1. Misuse of nozzle size
• Size does not meet the standard: In order to reduce costs, many companies use nozzles that do not meet the standard size. For example, the nozzle diameter may be only 5 mm or even smaller, or the nozzle radius does not meet the standard. These substandard nozzles cannot meet the requirements of the IEC 60529 standard at all, causing the test results to deviate seriously from reality, bringing huge errors to the evaluation of the product's waterproof performance [^IEC 60529^].
• Uncalibrated: Some companies knowingly use nozzles that have not been calibrated by a third party for testing. The size of these nozzles may become inaccurate due to errors in the production process or wear and tear after long-term use, but they turn a blind eye and continue to conduct the so-called "waterproof test". This behavior is simply a blatant provocation to the IEC 60529 standard, a disrespect for the entire industry, and a disregard for the safety of consumers' lives and property.
2. Wrong way to control water temperature
• Temperature loss: Some companies also have serious problems with water temperature control. They supply water directly from the hot water source to the sprinkler head without taking any measures to ensure the stability of the water temperature. This practice causes the water temperature to gradually decrease in the pipe and cannot meet the standard requirement of 80±5℃.
• Irregular testing: Some companies even start testing before the water temperature stabilizes, or ignore changes in water temperature during the test. This irresponsible behavior not only wastes testing resources, but also misleads the company's own assessment of product quality, burying a huge hidden danger for the product's future market performance.
These companies are willing to sacrifice product quality and safety for the sake of immediate profits. This behavior is a great violation of professional ethics, a great harm to consumer rights, and a great harm to the entire industry. They are not only deceiving consumers, but also deceiving themselves, which will eventually lead to a crisis of trust in the entire industry and damage the reputation of the entire industry.
