For large specimens that cannot be accommodated in an oscillating tube chamber – Such as electrical power cabinets, telecommunication base stations, or entire road vehicles – Manual testing is the required methodology. Our Hand-held Spray Nozzle is the definitive testing instrument designed to meet the strict physical requirements of IEC 60529 Figure 5 and ISO 20653 Figure 5. This precision tool allows engineers to perform localized water ingress validation, ensuring that seals, joints, and interfaces remain secure under spraying and splashing conditions.

IEC 60529 & ISO 20653 Figure 5 hand-held spray nozzle provides a controlled environment to simulate different intensities of water ingress as defined by IEC 60529 and ISO 20653. Figure 5 Hand-held Spray Nozzle from Wewon Environmental Chambers Co., Ltd. is not just a testing tool; it is a precision instrument designed for longevity and absolute compliance with international standards.

The spray head is crafted using advanced CNC (Computer Numerical Control) technology to ensure that every one of the 121 holes is drilled to the exact  mm specification. Made from pure high-grade brass, the head undergoes a mirror-polishing process, resulting in a flawless, aesthetic finish that also enhances corrosion resistance.	1. CNC Precision-Machined Spray Head:
To prevent the formation of verdigris (green copper patina) caused by long-term exposure to water and minerals, the brass surface is treated with a specialized anti-rust protective coating. This ensures the equipment maintains its professional appearance and structural integrity even after years of laboratory use.	2. Advanced Anti-Oxidation Coating:
All other critical components, including the handle and support structures, are fabricated from SUS304 stainless steel. This choice of material guarantees maximum durability, exceptional rust resistance, and the strength needed to withstand high-pressure water flow.	3. Heavy-Duty SUS304 Construction:
Designed for convenience, the nozzle features a standardized connector that can be directly connected to your laboratory’s tap water supply. This eliminates the need for complex pumping systems in basic testing scenarios.	4. The Plug-and-Play Easy Integration:
The ergonomic design allows for rapid transition between test ratings. By simply locking or removing the movable shield, the operator can switch between IPX3 and IPX4 modes in seconds, significantly improving testing efficiency.	5. Simplified Test Mode Switching:

The IEC 60529 & ISO 20653 Figure 5 hand-held spray nozzle serves as a critical diagnostic instrument for evaluating the Ingress Protection (IP) integrity of products.	Primary Function & Industrial Applications
Its core purpose is to simulate standardized rainfall and splashing water conditions, allowing engineers to assess the physical and functional reliability of equipment under controlled environmental stress.
By replicating harsh weather scenarios, this specialized tool helps manufacturers determine whether a product’s enclosure can effectively prevent water from reaching sensitive internal components.
This testing apparatus is indispensable across a wide spectrum of sectors where outdoor durability is a priority:	Broad Industry Applications
Electronics & Electrical Engineering: Verifying the sealing performance of consumer electronics and precision electrical components.
Lighting Systems: Testing the moisture resistance of outdoor LED lamps, street lighting, and architectural floodlights.
Industrial Enclosures: Ensuring that large-scale electrical cabinets, distribution boxes, and control panels remain safe and operational in rain-prone environments.
Automotive & Transportation: Rigorously assessing the water-tightness of automobiles, motorcycles, and critical sub-systems—such as headlights, side mirrors, and electronic sensors – against heavy rain and road spray.
Beyond simple pass/fail testing, the data generated by the Figure 5 Spray Nozzle provides a comprehensive scientific foundation for the entire product lifecycle:	A Scientific Basis for Quality Excellence
Design & Optimization: During the R&D phase, it identifies potential structural weaknesses in seals and gaskets, allowing for early-stage design improvements.
Verification & Inspection: It serves as a vital tool for product verification, factory inspections, and final quality control (QC).
Global Compliance: It ensures that products meet the stringent entry requirements for international markets, providing documented proof of adherence to global safety and performance standards.
Ultimately, Using this standardized nozzle helps manufacturers reduce post-market failure rates, enhance brand reputation, and ensure long-term user safety.

Standardized Operating Procedures (SOP) for IPX3 & IPX4 Testing: Adhering to these specific steps is vital for manufacturers of automotive parts, outdoor LED lighting, and industrial electrical cabinets. By maintaining the precise 50-150 kPa pressure range and the correct shield positioning, The hand-held spray nozzle provides the scientific data needed for product reliability audits and R&D optimization. To ensure consistent and repeatable results that fully comply with IEC 60529 Figure 5 and ISO 20653, Operators should follow these precision-guided steps when using the Hand-held Spray Nozzle.

The IPX3 test is designed to verify that the specimen’s enclosure can withstand water sprayed at an angle of up to 60° from the vertical.	1. IPX3 Testing: Protection Against Spraying Water
Preparation: Securely connect the high-pressure water hose to the nozzle’s inlet and activate the main water supply.
Configuring the Mode: Loosen the adjustment screws on both sides of the spray head. Slide the movable brass shield forward by 30° until it reaches the limit of the slot, then lock it firmly. This positioning effectively blocks the top one-third of the spray, creating the exact “spraying water” pattern required for IPX3 compliance.
Pressure Calibration: Open the flow control valve. Monitor the integrated pressure gauge on the handle and adjust the valve until the internal pressure is stabilized within the 50 kPa to 150 kPa range.
Execution & Duration: Direct the nozzle at all feasible surfaces of the specimen. The total test time is calculated at 1 minute per square meter of the enclosure’s surface area (excluding the mounting base), with a guaranteed minimum test duration of 5 minutes.
The IPX4 test is a more rigorous assessment, simulating water splashing against the enclosure from all possible directions (360°).	2. IPX4 Testing: Protection Against Splashing Water
Preparation: Ensure the water connection is leak-free and the supply system is operational.
Configuring the Mode: Loosen the side screws and slide the movable shield backward by 30° to its retracted position. This uncovers the entire spray head, allowing for the full, unobstructed “splashing water” delivery required by the IPX4 standard.
Pressure Calibration: Activate the spray and modulate the valve until the pressure gauge indicates a steady state between 50 kPa and 150 kPa.
Execution & Duration: Systematically spray the specimen from every angle, paying close attention to critical interfaces, gaskets, and cable entries. Like the IPX3 test, the duration is determined by the surface area (1 min/m²), ensuring the test lasts at least 5 minutes to provide a conclusive safety assessment.

●	Q: Does this nozzle come with a calibration certificate ?
●	A: Yes, each unit is checked for hole diameter and flow distribution to ensure 100% compliance with the Figure 5 diagram in the IEC 60529 standard.
●	Q: Can it be used for IPX4K testing ?
●	A: While the spray pattern is similar, IPX4K (defined in ISO 20653) typically requires higher pressure and flow. This nozzle is optimized for the standard IPX3/IPX4 10 L/min flow rate.
