IEC 60335 IP1X IP2X IP3X IP4X Test Probe ABCD
Products Description:
IP1X-IP4X Test Fingers / Test Probes, designed in strict compliance with the standards of IEC 60529, GB/T 4208 and IEC 61032, are important instruments for the testing of IP solid particle protection rating (the first characteristic digit). They simulate the intrusion of human hands, fingers and tools respectively to verify the protection capability of product enclosures against solid foreign objects and accidental contact by the human body.
1.IP1X Test Probe A
To verify the product's capability to prevent the intrusion of solid foreign objects with a diameter of ≥50mm and protect human back of the hand from touching hazardous parts.
2.IP2X Test Finger B
To verify the product's capability to prevent the intrusion of solid foreign objects with a diameter of ≥12.5mm and protect human fingers from touching hazardous parts.
3.IP3X Test Probe C
To verify the product's capability to prevent the intrusion of solid foreign objects with a diameter of ≥2.5mm and protect human body from hazardous parts being contacted by tools.
4.IP4X Test Probe D
To verify the product's capability to prevent the intrusion of solid foreign objects with a diameter of ≥1.0mm and protect human body from hazardous parts being contacted by thin metal wires.

FAQ:
Q:What's The Difference Between IP1X IP2X IP3X IP4X IP Code Test Equipment?
A:Key Differences Between IP1X, IP2X, IP3X, and IP4X Tests
The core differences between IP1X IP2X IP3X and IP4X lie in test probe dimensions, applied force, protected particle size, and application scenarios, with each level progressively improving isolation against small solids and internal hazardous components.
Quick Reference Table
| | | | | |
|---|
| Solid objects ≥50mm (back of hand / large tools) | | | Probe shall not fully enter the enclosure | Large fixed equipment, cabinets |
| Solid objects ≥12.5mm (fingers) | | | Probe shall not enter the enclosure | Desktop appliances, small household electronics |
| Solid objects ≥2.5mm (tools / thick wires) | | | Probe shall not contact hazardous internal components | Light outdoor equipment, security devices |
| Solid objects ≥1.0mm (thin wires / dust) | | | Probe shall not contact hazardous internal components | Small outdoor electrical devices, power tools |
Detailed Key Differences
1. IP1X
-Test: A 50mm IP1X test steel ball probe is pressed into enclosure openings with a force of approximately 50N.
-Purpose: Prevents the back of a hand or large tools from touching hazardous internal components and blocks large foreign objects from entering.
2. IP2X
-Test: The IP2X 12.5mm spherical finger probe is applied to all openings with a force of approximately 10–30N.
-Purpose: Prevents fingers from touching hazardous components; a common basic protection for household appliances.
3. IP3X
-Test: The ip3x 2.5mm diameter IP test rod is inserted with a force of approximately 3N; it must not contact hazardous internal components.
-Purpose: Prevents medium-sized foreign objects like screwdrivers or wires from touching hazardous components, enhancing protection for industrial scenarios.
4.IP4X
-Test: A 1mm diameter IP test finger probe is inserted with a force of approximately 1N; it must not contact hazardous internal components.
-Purpose: Prevents tiny foreign objects like thin wires or dust from touching hazardous components; a common protection for outdoor equipment.
Additional Notes
Suffix Letters: Standard suffixes (A/B/C/D) further define test probes (e.g., B for fingers, C for tools, D for cables), directly corresponding to the levels above.
Relationship to Dust Protection: IP1X–IP4X focus on preventing solid foreign objects from touching/entering equipment, while IP5X/IP6X are dedicated dust protection levels—these are distinct and should not be confused.
