THIRD DIGIT OF IP CODE

Hello KOTUU2

Please be advised that use of all CAPITALS in your Post is the equivalent of shouting very loudly.

There is a fine chart here for the first 2 digits, the ones you probably are aware of.

<"EN 60529 outlines an international classification system for the sealing effectiveness of enclosures of electrical equipment against the intrusion into the equipment of foreign bodies (i.e. tools, dust, fingers) and moisture.

This classification system utilizes the letters "IP" ("Ingress Protection") followed by two or three digits.

A third digit is sometimes used.

An "x" is used for one of the digits if there is only one class of protection; i.e. IPX4 which addresses moisture resistance only.)">

Also please refer to explanation at General Dynamics ltronix

<"Rugged Rating Organizations and Standards

Ratings are set by various government agencies, industry groups and/or independent laboratories and are cited by manufacturers in order to establish a more exact degree of environmental protection and reliability. Some of the more common standards include:

IP Ratings (Ingress Protection) Rating for Equipment and Enclosures

A three-digit number established by the International Electrotechnical Commission, is used to provide an IP Rating to a piece of electronic equipment or to an enclosure for electronic equipment. The IP code indicates the level, or amount of the protection.

The three digits represent three different forms of environmental influence:

The first digit represents protection against ingress of solid objects.
The second digit represents protection against ingress of liquids.
The third digit represents protection against mechanical impact damage.

(*The third digit is often omitted, resulting in a 2-digit IP Rating covering ingress against solid objects and liquids only).

The larger the value of each digit, the greater the protection from that influence. As an example, a product rated as IP573 would be better protected against environmental factors than another similar product that was only rated as IP432.">

Trust that assists you, and please advise further if required.

Kind Regards....

Hello Spark,

Thanks for your suggestion. In some technical parameter, the third digit is alphabet. It is not numeric. Kindly let me know if there is some information concerning these numeric. for eg.IP23C....In this code what C is meant for. sometimes there is "S" in the third digit.

Thks and Regards,

Kotuu2.

Just to precis that a bit...

The IP rating is made up of the letters IP followed by three numbers.

The first number relates to the ingress of particles, fingers, wire, dust etc...

The second relates to the protection against water, drops, spray, submersible etc...

The third number, if used, relates to the protection from mechanical impact, 1 Joule, 2 Joules etc...

There is also another classification NEMA

that also uses "X" for uncoded criteria ... for example

NEMA4X

Does anyone know where to get the Chart for correlation

between the NEMA classification and the IP classification?

Hi KotoU2 This may Help

Hello coconutpete,

While your chart may be useful in its original size, when I expand the shrunken graphic you gave above, even to read what exact Australian Specification it come from, and indeed all of the probably useful information is "fuzzy" on my monitor.

Hopefully you'll call back and drag the chart larger, in your next post graphic, also give the relevant weblink, so I can go there direct, it would be appreciated.

Kind Regards....

hello coconutpete,

Could you post the larger image of this info or the related web address. I could not see the chart in your post. Thanks for your kind help.

Rgds,

Kotuu2.

Kotuu2,

There are 3 digits for a complete description: IPxyz

All digits (x,y,z) are numbers from 0 - 9 (0 = no protection, 9 = maximal protection)

x = protection against solids

y = protection against liquids

z = protection against mechanical impact

I never saw the third digit as a letter.

Hello,

According to the link http://www.gobookvr-2.com/standards.asp

"A three-digit number established by the International Electrotechnical Commission"

Which IEC standard contains the three-digit number series?

I am presently trying to locate further information, re the third letter/numeral etc of the IP code/s.

I'll advise further as soon as possible.

Hello KOTUU2 and others interested.

coconutpete has shown me the full-sized chart from Pierlite, Australia, which is not a full-size picture in his earlier Post.

The actual Chart File is: Ingress Protection (Ip) Rating (278KB) file in .PDF, from here:

In that file, it refers to the source standards for the various IP categories.

Hello,

According to the link:

http://www.pierlite.com.au/download.php?id=791&filename=03.pdf

column 1 and 2 are together and column 3 are not connected to 1 and 2.

The is no text according to IP-code with 3 numbers in the text below the pictures.

I think that the most likely explanation is this:

IP-code according to IEC 60529 (IEC 529) , example IP65

and the question according to the third digit, Protection against impact, is

IK-code according to IEC 62262 or EN 50102, example IK07.

The right way should be IP65/IK07 , Not IP657.

Is this making sense?

Exodus28

What does the addition of a letter after the first two numbers indicate? I have one for dust/water written as IP6K6K. I understand the 6's but what do the K's specify?

WOOO - this link has it all. Probably pay to get a copy of IEC standard also (can you send me a copy if you do ;-)

Hello Guest,

Thanks for that weblink to that .PDF Document, which I have downloaded.

If you were Registered at CR4, the GA Point would be added to your total.

from me

Kind Regards....

further thought on that.... the suplemental letters may be part of BS/EN standard rather than IEC???????
