Ingress Protection What is the IP Code ? The IP Code refers to the different levels of protection the enclosure provides and gives a means of classifying the degrees of protection from dust, water and impact afforded by electrical equipment and enclosures. For your IP Rating Converter click here
.
The code is separated into two characteristic numerals, the first numeral indicates the protection of hazardous parts and protection of equipment against ingress of foreign solid objects. The second numeral indicates protection of equipment against harmful ingress of liquids. Why does a Product need to be IP Tested ? The IP Standard is designed to test a products suitability for a specific environment. Many call up IP testing as a basic requirement for environmental testing against external influences such as water ingress, dust ingress and protection against contact with live parts. What IP Tests can Baseefa conduct ? Baseefa can carry out any IP testing as detailed in the table at the foot of the page. What Documentation will I Receive ? Certificate of Test Product submitted for test identified by serial number. Certificate of Test states that product with serial number xxxx has an ingress protection rating of IPXX.

IP Code From Wikipedia, the free encyclopedia
The IP Code, Ingress Protection Rating,[1] [2] sometimes also interpreted as International Protection Rating,[3] classifies and rates the degree of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in mechanical casings and with electrical enclosures.[4][5] The standard aims to provide users more detailed information than vague marketing terms such as waterproof. However, no edition of the standard is openly published for unlicensed readers. The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. For example, an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. IP22 or 2X are typical minimum requirements for the design of electrical accessories for indoor use.

Mechanical impact resistance An additional number has sometimes been used to specify the resistance of equipment to mechanical impact. This mechanical impact is identified by the energy needed to qualify a specified resistance level, which is measured in joules (J). This has now been superseded by the separate IK number specified in EN 62262. Although dropped from the 3rd edition of IEC 60529 onwards, and not present in the EN version, older enclosure specifications will sometimes be seen with an optional third IP digit denoting impact resistance. Newer products are likely to be given an IK rating instead. However there is not an exact correspondence of values between the old and new standards.

IPX Coding The letter X is used in any place in the code where specifying a digit is meant to be avoided. There may be various reasons for choosing this coding variant, such as marketing considerations. Thus, e.g. an IPX7 rating for a consumer device specifies that the device has water protection up to limited immersion, but gives deliberately no information as to whether the device has any protection against mechanical ingress or dust. Among other common IP ratings using the letter X are IPX4. IP2X is frequently used on electrical items to specify the item must prevent finger access to live terminals i.e plug sockets are IP2X.
IP69K German standard DIN 40050-9 extends the IEC 60529 rating system described above with an IP69K rating for high-pressure, high-temperature wash-down applications.[7] Such enclosures must not only be dust tight (IP6X), but also able to withstand high-pressure and steam cleaning.

The test specifies a spray nozzle that is fed with 80°C water at 8–10 MPa (80–100 bar) and a flow rate of 14–16 L/min. The nozzle is held 10–15 cm from the tested device at angles of 0°, 30°, 60° and 90° for 30s each. The test device sits on a turntable that rotates once every 12s (5rpm). The IP69K test specification was initially developed for road vehicles, especially those that need regular intensive cleaning (dump trucks, cement mixers, etc.), but also finds use in other areas (e.g., food industry, car wash centres).

The United States National Electrical Manufacturers Association (NEMA) also publishes protection ratings for enclosures similar to the IP rating system published by the International Electrotechnical Commission (IEC). However, it also dictates other product features not addressed by IP codes, such as corrosion resistance, gasket aging, and construction practices. Thus, while it is possible to map IP Codes to NEMA ratings that satisfy or exceed the IP Code criteria, it is not possible to map NEMA ratings to IP codes, as the IP Code does not mandate the additional requirements. The table above indicates the minimum NEMA rating that satisfies a given IP code, but can only be used in that way, not to map IP to NEMA.[8] North American enclosure rating systems are defined in NEMA 250, UL 50, UL 508, and CSA C22.2 N°. 94.
