IPX7 compliance is confirmed with the waterproof cover closed, meaning the device is rated to withstand temporary immersion in water up to 1 metre depth for 30 minutes under standard conditions.
Key Details
The IPX7 test was conducted in accordance with the immersion procedure defined in IEC 60529:1989+A1:1999+A2:2013. The following summarises the test method, environmental conditions, and acceptance criteria applied during evaluation of the Helios J1.
Test Environmental Conditions
| Parameter | Requirement |
|---|---|
| Temperature Range | 15 °C to 35 °C |
| Relative Humidity | 25% to 75% |
| Test Medium | Fresh water |
IPX7 Immersion Conditions
| Parameter | Specification |
|---|---|
| Immersion depth (enclosure height < 850 mm) | Lowest point 1,000 mm below water surface |
| Immersion depth (enclosure height ≥ 850 mm) | Highest point 150 mm below water surface |
| Test Duration | 30 minutes |
| Water Temperature Differential | Must not differ from equipment temperature by more than 5 K |
Acceptance Criteria
After immersion, the enclosure was inspected for water ingress. Any water that entered must not: interfere with correct operation or safety; deposit on insulation parts causing tracking along creepage distances; reach live parts or windings not designed to operate when wet; or accumulate near the cable entry or enter the cable.

Standards & Compliance
The ETENWOLF Helios J1 was evaluated against the following international standard governing degrees of protection provided by enclosures:
| Standard | Full Title | Scope |
|---|---|---|
| IEC 60529:1989+A1:1999+A2:2013 | Degrees of Protection Provided by Enclosures (IP Code) | Defines IPX7 immersion test method and acceptance criteria for protection against water ingress |
The IP (Ingress Protection) rating system classifies the degree of protection provided by the mechanical casing and electrical enclosures of devices. The second digit in the IPX7 rating specifically addresses liquid ingress:
- IPX7 — Complete, temporary immersion in water: the device can be immersed at a depth of up to 1 metre for up to 30 minutes without harmful water ingress.
The test category for this evaluation was an Entrusted Test, conducted entirely in-house by Waltek Testing Group. No subcontracting to external laboratories was involved.
Compliance with IPX7 is confirmed only when the waterproof cover is properly closed. Users should ensure all port covers and seals are securely fastened before any exposure to water.
