“Ingress Protection” First Digit: Solids Protection Second Digit: Liquids Protection
Ingress Protection (IP) and what it means
The IP Code (or International Protection Rating, sometimes also interpreted as Ingress Protection Rating*) consists of the letters IP followed by two digits and an optional letter. As defined in international standard IEC 60529, it classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures. The standard aims to provide users more detailed information than vague marketing terms such as waterproof.
The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. 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.
*Explanation of the letters IP is given in IEC 60529 (Ed. 2.1), clause 4.1
First Digit: Solids
The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects.
Second Digit: Liquids
Protection of the equipment inside the enclosure against harmful ingress of water.
ATEX directive: Classification of operating resources
Components and solutions with ATEX certification for all steps in the integration process
Legal directives such as NEC/CEC in the USA and Canada, and Europe’s 2014/34/EU (ATEX) are in place alongside other regulations to reduce the risk of explosions in high risk operating areas and increase industrial machine safety. For an ATEX certificate approval the areas will be divided by explosion hazard - risk zones.
Place of use and zoning, as well as ignition type and protection levels are govern the requirements placed on components, units and devices. Dilovas Systems gives you access to a wide variety of mechanical and electric drives with ATEX certification.
