IP Protection for Outdoor Radiant Heaters
Understanding the Ingress Protection (IP) for Outdoor Radiant Heaters
The IP protection standards, known as "Ingress Protection" in English, are established by the IEC (International Electrotechnical Commission) to indicate the degree of sealing of equipment. These standards are crucial for outdoor radiant heaters, ensuring their resistance to external conditions.
The IP code is represented in the form IPXY, where X represents the level of protection against solids and Y indicates the level of protection against liquids.
Table of Various IP Ratings
Protection Rating | 1st Digit (solid objects) | 2nd Digit (liquids) |
---|---|---|
0 | No protection | No protection |
1 | Protected against solid objects > 50 mm | Protected against vertically falling drops of water |
2 | Protected against solid objects > 12 mm | Protected against falling drops of water up to 15° from vertical |
3 | Protected against solid objects > 2.5 mm | Protected against water sprays up to 60° from vertical |
4 | Protected against solid objects > 1 mm | Protected against water splashes from all directions |
5 | Protected against dust | Protected against water jets from all directions using a 12.5 mm nozzle, 12.5 l/min |
6 | Totally protected against dust | Protected against water jets from all directions using a 22.5 mm nozzle, 100 l/min |
7 | / | Protected against the effects of temporary immersion (up to 1m) |
8 | / | Device submersible under specified conditions (prolonged immersion) beyond 1m and for 30 minutes. |
9 | / | Device submersible under specified conditions (prolonged immersion) beyond 1m and protection against high-pressure cleaning. |
9x | / | Device submersible under specified conditions (prolonged immersion) beyond 1m and protection against high-pressure cleaning (standard for food and kitchens). |
