The IEC has developed the ingress protection (IP) ratings, which grade the resistance of an enclosure against the intrusion of dust or liquids
Refer to the chart below for the ratings of relative protection of electrical enclosures: IP Ratings Guide. The IP rating normally has two (but may have three) numbers: Protection from solid objects or materials; Protection from liquids (water) Protection against mechanical impacts (commonly omitted, the third number is not a part of IEC 60529)
The following table outlines which IEC 60529 IP code each respective NEMA guideline meets. Ratings between the two standards are not directly equivalent: NEMA ratings also require additional product features and tests (such as functionality under icing conditions, enclosures for hazardous areas , knock-outs for cable connections and others) not ...
Below is an easy to follow reference chart to help you decide which IP rating you need or have.
The rating guide of the two numerals comprising the IP code as defined in IEC 60529
An IP Rating (also known as an Ingress Protection Rating or International Protection Rating) is a way of showing the effectiveness of electrical enclosures in blocking foreign bodies such as dust, moisture, liquids, and accidental contact (2022).
IP Rating Chart. The IP Rating chart below gives you a shorthand sort of way to understand the various ratings from IP11 to IP9K6. The way to read the chart is to go across to match up the Solids rating (the first digit). Then move down to find the matching Water rating (the second digit).
An IP rating includes two digits preceded by the prefix “IP”. The first digit specifies the protection from solid objects and the second digit the protection from liquids. For example, IP56 means protection from harmful deposits of dust and protection from heavy seas or strong jets of water from all directions.
IP Ratings Chart and Table You can find out what each digit in a standard IP code means in the IP ratings table below. By using this ingress protection chart, you can determine what hazards and scenarios a given item's mechanical or electrical components should be protected from.
Ingress protection (IP) ratings guide. IP ratings are represented by combining the first and second digits of the below columns. 1st numeral - solid foreign objects. 0. No protection. Protected against solid foreign objects of. 50 mm Ø and greater. Protected against solid foreign objects of 12,5 mm Ø and greater.
