| To Classifies and Rates the degree of protectionIEC (International Electro-technical Commission) Introducesa standard IEC 60529. |
What is IEC 60529:
IEC 60259standard determines how well a enclosure(EUT)protects internal working parts from dust& water and fingers, tools, and wires. It is used for consumer safety and enclosure testing.
Scope of This Standard :
This standard applies to the classification of degrees of protection provided by enclosures for electrical equipment with a rated voltage not exceeding 72,5 kV
IEC 60259 : Dust and Water Resistance by Category
The IEC 60259ratings use a two-digit system to Providethe level of protection that each product features. Ratings are listed as “IP__ __,” with the first digit indicating solid ingress protection, and the second digit representing liquid ingress protection. Additional letters may follow the two digits, specifying additional ingress protection.
| There are six levels of solid ingress protection under the IEC 60259 rating system: | |
| l | The product is protected against entryby a solid object larger than 50 mm in size, such as a hand. |
| l | The product is protected against entryfrom solid objects larger than 12.5 mm, such as a finger |
| l | The product is protected against entryof solid objects larger than 2.5 mm, such as a screwdriver |
| l | The product protects against entryby solid objects larger than 1mm, such as a wire |
| l | The product is protected against a limited amount of dust exposure. Dust entrywill not interfere/Degradewith product operation assuming dust exposure |
| l | Total dust protection. Dust ingress is not possible to enter in Product during Testing |

Equipments Used for IP Testing (Solid)
| Second digit representing nine levels of water ingress protection | |
| l | The product is protected under vertically falling water drops. Some limited ingress is allowed |
| l | When tilted at 15° from the vertical, the product resists vertically falling water drops. Again, limited ingress is permitted |
| l | When water sprays are applied up to 60° from the vertical, the product allows limited intrusion for a period of three minutes |
| l | The product allows limited ingress when water is splashed on it from all directions |
| l | Limited ingress is permitted when water jets are applied to the product |
| l | Heavy seawater and powerful jets of water will not enter the product in damaging quantities |
| l | The product is protected against the effects of water intrusion when immersed in water between 15 cm and 1 m for up to 30 minutes |
| l | The product withstands water intrusion when immersed in water under pressure for long periods |
| l | The product is protected against the effects of high-pressure and high-temperature water jets |
