Electrical and electronic devices are increasingly used in challenging environments, where they may be exposed to dust, moisture, or water. To ensure their long-lasting and safe operation, proper protection is essential. The IP classification (Ingress Protection), developed under the international standard IEC 60529 (PN-EN 60529:2003), defines the level of protection that a device's casing provides against solid objects and liquids. This article explains the IP classification, how to interpret the numbers in an IP code, and what IP44 specifically means.
What is the IP classification?
The IP classification is an international system used to rate the level of protection devices offer against external factors. It’s represented by two numbers following the letters "IP." First number: Indicates protection against solid objects (e.g., dust, dirt). Second number: Indicates protection against liquids (e.g., water). Understanding this code is essential, especially when selecting devices for demanding environments, ensuring their reliable performance and safety.
What do the numbers in an IP code represent?
An IP code is a standardized indicator consisting of two digits:
- First number (0–6) – protection against solid objects:
- IP0X: No protection against solid objects.
- IP1X: Protection from large objects (over 50 mm, e.g., a hand).
- IP2X: Protection from objects larger than 12.5 mm (e.g., fingers).
- IP3X: Protection from objects larger than 2.5 mm (e.g., tools).
- IP4X: Protection from objects larger than 1 mm (e.g., thin wires).
- IP5X: Partial protection against dust; small amounts may enter but do not affect operation.
- IP6X: Complete dust-tight protection.
- Second number (0–9) – Protection against liquids:
- IPX0: No protection against water.
- IPX1: Protection from vertically dripping water.
- IPX2: Protection from water dripping at up to 15° angles.
- IPX3: Protection from water sprays up to 60° from vertical.
- IPX4: Protection from splashing water from any direction.
- IPX5: Protection from low-pressure water jets.
- IPX6: Protection from high-pressure water jets.
- IPX7: Protection from temporary immersion in water up to 1 meter.
- IPX8: Protection from continuous immersion at a depth specified by the manufacturer.
- IPX9: Protection from high-pressure, high-temperature water (intense cleaning).
Examples of IP protection – what does IP44 mean?
The code IP44 indicates that a device is protected against both solid objects and moisture:
- First digit (4): Protection from solid objects larger than 1 mm, such as small wires or tools.
- Second digit (4)Protection against water splashed from any direction. This means the device is safeguarded against splashes and light rain, making it suitable for use in moderately humid conditions.
This makes IP44 a common choice for devices used in environments with moderate exposure to dust and water, such as bathrooms, kitchens, balconies, and gardens.
Applications of IP44 devices
Devices with an IP44 rating are widely used in both residential and commercial settings, where moderate contamination and occasional water exposure are expected. Examples include:
- Outdoor lighting – Lamps for terraces, pathways, or gardens, resistant to rain and dust.
- Electrical installations in damp rooms – Outlets and switches in bathrooms or kitchens exposed to occasional splashes.
- Garden or garage electronics – Devices protected against dust and light water contact.
RCC – Experts in IP44 testing
RCC specializes in testing device protection according to international standards, including IP44. We provide comprehensive testing and certification services to evaluate how well your products are protected from solid particles and water.
How does RCC test protection against solid objects?
The RCC laboratory conducts tests in compliance with the IEC 60529 standard, which evaluates protection against solid objects such as dust and dirt. The tests include simulations of the device's operation in environments with fine particles to ensure that the casing effectively prevents the entry of objects larger than 1 mm in diameter.
How does RCC test water resistance?
RCC's water protection tests include detailed evaluations of device resistance to dripping and splashing water. Specialized measurement equipment is used to simulate conditions that meet IP44 requirements, ensuring the reliability of devices in moderately humid environments.
