IS/ IEC 60529-1 Degrees of protection provided by enclosures (IP Code)
ITC india pvt ltd is conducting Ingress Protection as per IEC 60529-1. With the help of this enclosures can be accessed against ingress of solid bodies and/ or liquids. As per the IP code identified by the manufacturer, we do the testing to measure the effects of exposure, and give the appropriate IP rating. It is signified with a number like IP65, IP 67 etc.
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.
The object of this standard is to give:
- a) Definitions for degrees of protection provided by enclosures of electrical equipment as regards:
1) Protection of persons against access to hazardous parts inside the enclosure;
2) Protection of the equipment inside the enclosure against ingress of solid foreign objects;
3) Protection of the equipment inside the enclosure against harmful effects due to the ingress of water.
- b) Designations for these degrees of protection.
- c) Requirements for each designation.
- d) Tests to be performed to verify that the enclosure meets the requirements of this standard.
IP Code with optional letters
First characteristic numeral
|Solid object Protection|
|Level ( The first digit for solid particle protection )||Degree of Protection|
|Diameter of the solid particle against which testing is performed|
IP0X-Not protectedIP1X>50mmSolid foreign objects of dia 50mm and greaterIP2X>12.5mmSolid foreign objects of dia 12.5mm and greaterIP3X>2.5mmSolid foreign objects of dia 2.5mm and greaterIP4X>1mmSolid foreign objects of dia 1mm and greaterIP5XProtection against DustDust ( protected)IP6XDust TightAccess to hazardous parts with wire Dust
- The full diameter of the object probe must not pass through the opening of the enclosure under test.

|M||Tested for harmful effects due to ingress of water when the movable parts of the equipments are in motion|
|S||Tested for harmful effects due to ingress of water when the movable parts of the equipments are in stationary|
|W||Suitable for use under specified weather condition|
This is the standard that narrates the degree of protection dispense by the enclosures of electrical equipments. It must not be assumed that all the listed degree of protection is applicable to a particular type of equipment. Manufacturer must be consulted to determine the degree of protection.
The second edition of IEC 60529 takes account of experienced with the first edition and clarifies the requirements. It provides IP codes by an additional letter A, B, C or D if the actual protection of the persons against access to hazardous parts is higher than that indicated by the first characteristic numerals.
