What do Military Codes and IP Ratings Mean?

We always see that a product is rated to specific military standards - but what do these ratings mean and why is it important for walkie talkies?

What is an IP Rating?

Ingress Protection (IP) are ratings in place to illustrate the resistance/protection level of devices from liquids/solids - like water and dust.

The IP Code will have 2 digits

The First Digit

Indicate the resistance of radios to solid objects.

0  No Protection
1  Any large surface of the body
2  Fingers or similar sized objects ( > 12.5mm)
3  Tools ( > 2.5 mm)
4  Most screws, wires ( > 1mm)
5  Mild entry of dust
6  Any entry of dust


The 2nd Digit

 Rates the resistance of the radio to water/liquids.

0  No protection
1  Vertically dripping water
2  Dripping water up to a 15* angle
3  Spray up to 60* angle
4 Splashing water from any direction
5  Water projected from a nozzle (<6.3mm)
6  Powerful jet nozzle (<12.5mm)
7 Temporary immersion in water
8 Continuous immersion in water


Two Way Radio IP55 - Level of Protection

The "IP55" rating is a standard classification used to describe the level of protection provided by an electrical enclosure, device, or equipment against the intrusion of solid particles (like dust) and water. The IP code, which stands for "Ingress Protection" or "International Protection," consists of two digits. In the case of IP55:

  1. The first digit (5) indicates protection against solid objects, specifically dust and other particulates. A rating of "5" means that the device is protected against dust to the extent that it should not interfere with its operation. However, it is not completely dust-tight.

  2. The second digit (5) signifies protection against water. A rating of "5" in this position means the device is protected against low-pressure water jets from all directions. It can withstand water projected by a nozzle (6.3mm nozzle) against the enclosure from any direction without harmful effects. It's important to note that an IP55 rating does not imply complete immersion protection.

For walkie talkies, IP55 is important for several reasons:

  1. Dust Resistance: Walkie talkies used in outdoor environments, construction sites, or other dusty locations need to be protected against dust and particulate matter that could infiltrate and potentially damage their internal components. An IP55 rating ensures that the device can continue to function effectively even in dusty conditions.

  2. Water Resistance: Walkie talkies can be exposed to rain, splashes, or even sprayed with water in various scenarios. The IP55 rating means that they can handle these situations without suffering from water damage. This is especially important for outdoor enthusiasts, first responders, and construction workers who rely on walkie talkies in unpredictable weather conditions.

  3. Reliability: In mission-critical situations, the reliability of communication equipment like walkie talkies is paramount. An IP55 rating provides a level of confidence that the devices won't fail due to dust or water exposure, ensuring uninterrupted communication when it's needed most.

  4. Versatility: Walkie talkies with IP55 ratings are versatile and suitable for a wide range of applications, including outdoor adventures, hiking, camping, and various professional uses. Users can have peace of mind knowing their devices are designed to handle challenging environmental conditions.

  5. Compliance: IP ratings are internationally recognized standards, providing a common language for manufacturers and users to describe a product's level of protection. This makes it easier for users to make informed decisions when selecting walkie talkies for their specific needs.


MIL-STD-810 - Durability and Performance

MIL-STD-810, short for "Military Standard 810," is a series of rigorous testing standards and procedures developed by the U.S. Department of Defense to evaluate the durability and performance of equipment under various environmental conditions. These conditions can include extreme temperatures, high humidity, exposure to dust, sand, and other particulates, as well as resistance to mechanical shock and vibrations, among others.

The ratings and specifications outlined in MIL-STD-810 provide a standardized framework for testing and assessing the reliability of equipment in challenging real-world scenarios. These standards are not limited to military equipment; they are also widely used in industries such as aerospace, manufacturing, and outdoor recreational equipment.

For walkie talkies, MIL-STD-810 certification is crucial for several reasons:

  1. Reliability in Harsh Environments: Walkie talkies are often used in demanding and unpredictable environments, including military operations, search and rescue missions, construction sites, and outdoor adventures. MIL-STD-810 certification ensures that these devices can continue to function effectively in extreme conditions, such as extreme heat or cold, heavy rain, dust storms, and rugged terrains.

  2. Durability: Walkie talkies with MIL-STD-810 certification are built to withstand physical shocks and vibrations. This is vital for military personnel, first responders, and industrial workers who may subject their equipment to rough handling or accidental drops. The certification ensures that the devices won't fail due to these impacts.

  3. Protection Against Dust and Particles: Walkie talkies often need to operate in dusty or sandy environments, such as construction sites or deserts. MIL-STD-810 testing includes evaluations for dust and particle ingress, ensuring that the devices remain operational and don't suffer from internal damage due to particle infiltration.

  4. Resistance to Moisture: In wet conditions or high humidity environments, MIL-STD-810-certified walkie talkies maintain their functionality and resist water damage. This is particularly important for military and outdoor applications where exposure to moisture is common.

  5. Consistency and Standardization: MIL-STD-810 provides a consistent and standardized method for testing and evaluating equipment, which is valuable for manufacturers and users alike. It ensures that products from different manufacturers can be compared based on their performance under the same set of challenging conditions.
