    IP Code: Explanation of The Letters IP Is Given in IEC 60529 (Ed. 2.1), Clause 4.1

    Uploaded by

    Shannon Garcia
    The IP Code consists of letters and digits that classify the degrees of protection provided by electrical enclosures against solid objects, dust, water, and accidental contact. The first digit refers to protection against solid objects, ranging from 0 (no protection) to 6 (dust tight). The second digit refers to protection against liquids, ranging from 0 (no protection) to 8 (protected against long-term immersion). An IP rating of IP22, for example, indicates protection against fingers and vertically dripping water. IP ratings provide more detailed information than vague terms to inform users of appropriate indoor and outdoor applications.

    IP Code

    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

    Sample IP Rating

    IP -

    First Digit: Solids

    Second Digit: Liquids

    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.

    Level

    Object size protected against

    Effective against

    Not protected

    No protection against contact and ingress of objects

    >50mm

    Any large surface of the body, such as the back of the hand, but no
    protection against deliberate contact with a body part.

    >12.5mm

    Fingers or similar objects.

    >2.5mm

    Tools, thick wires, etc.

    >1mm

    Most wires, screws, etc.

    Dust Protected

    Ingress of dust is not entirely prevented, but it must not enter in

    sufficient quantity to interfere with the satisfactory operation of the


    equipment; complete protection against contact.
    6

    Dust Tight

    No ingress of dust; complete protection against contact.

    Second Digit: Liquids


    Protection of the equipment inside the enclosure against harmful ingress of water.

    Level

    Object size protected against

    Effective against

    Not protected

    Dripping watter

    Dripping watter (vertically falling drops) shall have no harmfull effect.

    Dripping water when tilted up to


    15

    Vertically dripping water shall have no harmful effect when the


    enclosure is tilted at an angle up to 15 from its normal position.

    Spraying water

    Water falling as a spray at any angle up to 60 from the vertical shall


    have no harmful effect.

    Splashing water

    Water splashing against the enclosure from any direction shall have
    no harmful effect.

    Water jets

    Water projected by a nozzle (6.3mm) against enclosure from any


    direction shall have no harmful effects.

    Powerful water jets

    Water projected in powerful jets (12.5mm nozzle) against the


    enclosure from any direction shall have no harmful effects.

    Immersion up to 1m

    Ingress of water in harmful quantity shall not be possible when the


    enclosure is immersed in water under defined conditions of pressure
    and time (up to 1 m of submersion).

    Immersion beyond 1m

    The equipment is suitable for continuous immersion in water under


    conditions which shall be specified by the manufacturer. Normally,
    this will mean that the equipment is hermetically sealed. However,
    with certain types of equipment, it can mean that water can enter but
    only in such a manner that it produces no harmful effects.
