IP Ratings - What do those numbers mean? IP54? IP67?
In the world of professional telecommunications, a radio is only as good as its ability to survive the environment it operates in. Whether you are managing a high-pressure construction site, a dusty mining operation, or a marine rescue mission, understanding Ingress Protection (IP) Ratings is essential to ensuring operational longevity.
An IP rating tells you exactly how much "punishment" a device can take from solids (dust) and liquids (water).
Decoding the Numbers: What do they mean?
An IP rating consists of two digits (e.g., IP67). Each digit represents a specific level of protection:
- The First Digit (0–6): Protection against Solids (Dust/Debris).
- The Second Digit (0–9): Protection against Liquids (Water).
Ingress Protection (IP) Rating Reference Chart
Use the table below to identify the specific protection level of your equipment.
| First Digit: Protection against ingress of solids | Second Digit: Protection against ingress of liquids | |
|---|---|---|
| 0 | No protection | No protection |
| 1 | Protected against solid objects over 50mm e.g. hands, large tools | Protected against vertically falling drops of water. |
| 2 | Protected against solid objects over 12mm e.g. hands, large tools | Protected against direct sprays of water up to 15° from vertical. |
| 3 | Protected against solid objects over 2.5mm e.g. wire, small tools | Protected against direct sprays of water up to 60° from vertical. |
| 4 | Protected against solid objects over 1.0mm e.g. wires | Protected against water sprayed from any direction. Limited ingress permitted. |
| 5 | Limited protection against dust ingress (no harmful deposit) | Protected against low pressure water jets from any direction. Limited ingress permitted. |
| 6 | Totally protected against dust ingress. | Protected against high pressure water jets from any direction. Limited ingress permitted. |
| 7 | Protected against immersion between 15cm and 1M. | |
| 8 | Protected against long periods of immersion under pressure. | |
| 9 |
Common Industry Benchmarks: IP54 vs. IP67
When browsing the Radio Warehouse catalogue, you will most frequently see these two standards:
IP54: The "Commercial Standard"
- What it means: Dust-resistant and splash-proof.
- Suitable for: indoor & outdoor environments, including using the radio in the rain & bad weather.
IP67: The "Mission Critical" Standard
- What it means: Completely dust-tight and fully waterproof/submersible.
- Best for: Heavy construction, mining, wood chip mills, swimming pools, and emergency services.
If your team works in very dusty / dirty environments, or drops a radio into a body of water where it may be submerged, an IP67-rated device ensures the communication line stays open.
Why IP Ratings Matter for Your Bottom Line
Choosing a radio with an insufficient IP rating often leads to "untraceable" failures—corroded internal circuits or muffled speakers caused by fine dust particles.
At Radio Warehouse, we ensure that our commercial-grade solutions from Icom, Kenwood, and Motorola are matched to your specific environmental hazards.
Investing in the correct IP rating today prevents the "hidden cost" of frequent hardware replacements tomorrow.
The "Intrinsically Safe" Distinction
Please note that an IP rating (water/dust) is not the same as an IS (Intrinsically Safe) rating.
If your environment involves explosive gases or combustible dust (Refineries/Grain Silos), you require specialised IS-certified hardware.
IMPORTANT NOTICE
Waterproof Radio Care
Depending on the specific model you have purchased, your radio will have different waterproof ratings regarding submersion, depth, and time in water.
To maintain warranty provisions and prevent corrosion, even waterproof radios require preventative care. Please follow these essential steps to protect your investment:
- Post-Submersion Care: Radios must be washed down with warm, clean water and wiped dry immediately after any submersion.
- Connector Protection: Side accessory protection covers must remain fitted when not in use.
- Knob Integrity: All control knobs must be in place; removing them can damage the internal seals.
- Weekly Maintenance: We recommend cleaning radios, batteries, and chargers weekly with warm, clean water. Wiping down your equipment removes chemicals and residue buildup from contacts and housings.
IP67 Standard Note: Under IP67 immersion standards, the radio is rated for immersion in non-sea water for 30 minutes at a depth of 1 meter.
