This table shows what each digit or part of the IP (International protection) code represents.

IP indication Solid particle protection Liquid ingress protection
IP Single numeral: 0–6 Single numeral: 0–9

 

First digit: Solid particle protection

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 sized Effective against Description
0 No protection against contact and ingress of objects
1 >50 mm Any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part
2 >12.5 mm Fingers or similar objects
3 >2.5 mm Tools, thick wires, etc.
4 >1 mm Most wires, slender screws, large ants etc.
5 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.
6 Dust tight No ingress of dust; complete protection against contact (dust tight). A vacuum must be applied. Test duration of up to 8 hours based on air flow.

 

Second digit: Liquid ingress protection

The second digit indicates the level of protection that the enclosure provides against harmful ingress of water.

Level Protection against Effective against
1 Dripping water Dripping water (vertically falling drops) shall have no harmful effect on the specimen when mounted in an upright position onto a turntable and rotated at 1 RPM.
2 Dripping water when tilted at 15° Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle of 15° from its normal position. A total of four positions are tested within two axes.
3 Spraying water Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect, utilizing either: a) an oscillating fixture, or b) A spray nozzle with a counterbalanced shield.

Test a) is conducted for 5 minutes, then repeated with the specimen rotated horizontally by 90° for the second 5-minute test. Test b) is conducted (with shield in place) for 5 minutes minimum.

4 Splashing of water Water splashing against the enclosure from any direction shall have no harmful effect, utilizing either: a) an oscillating fixture, or b) A spray nozzle with no shield.

Test a) is conducted for 10 minutes. Test b) is conducted (without shield) for 5 minutes minimum.

5 Water jets Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects.
6 Powerful water jets Water projected in powerful jets (12.5 mm nozzle) against the enclosure from any direction shall have no harmful effects.
7 Immersion, up to 1 m depth 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).
8 Immersion, 1 m or more depth The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. 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. The test depth and/or duration is expected to be greater than the requirements for IPx7, and other environmental effects may be added, such as temperature cycling before immersion.
9 Powerful high temperature water jets Protected against close-range high pressure, high temperature spray downs.

Smaller specimens rotate slowly on a turntable, from 4 specific angles. Larger specimens are mounted upright, no turntable required, and are tested freehand for at least 3 minutes at distance of 0.15–0.2 m.

There are specific requirements for the nozzle used for the testing.

This test is identified as IPx9 in IEC 60529.

RFC 1893 - SMTP Extended Error MessagesImage

   For more detail about the RFC1893 : http://www.faqs.org/rfcs/rfc1893.html

   The class sub-code provides a broad classification of the status.
   The enumerated values the class are defined as:

    2.X.X   Success

       Success specifies that the DSN is reporting a positive delivery
       action.  Detail sub-codes may provide notification of
       transformations required for delivery.

    4.X.X   Persistent Transient Failure

       A persistent transient failure is one in which the message as
       sent is valid, but some temporary event prevents the successful
       sending of the message.  Sending in the future may be successful.

    5.X.X   Permanent Failure

       A permanent failure is one which is not likely to be resolved by
       resending the message in the current form.  Some change to the
       message or the destination must be made for successful delivery.



       X.0.X   Other or Undefined Status

          There is no additional subject information available.

       X.1.X   Addressing Status

          The address status reports on the originator or destination
          address.  It may include address syntax or validity.  These
          errors can generally be corrected by the sender and retried.

       X.2.X   Mailbox Status

          Mailbox status indicates that something having to do with the
          mailbox has cause this DSN.  Mailbox issues are assumed to be
          under the general control of the recipient.

       X.3.X   Mail System Status

          Mail system status indicates that something having to do
          with the destination system has caused this DSN.  System
          issues are assumed to be under the general control of the
          destination system administrator.

       X.4.X   Network and Routing Status

          The networking or routing codes report status about the
          delivery system itself.  These system components include any
          necessary infrastructure such as directory and routing
          services.  Network issues are assumed to be under the
          control of the destination or intermediate system
          administrator.

       X.5.X   Mail Delivery Protocol Status

          The mail delivery protocol status codes report failures
          involving the message delivery protocol.  These failures
          include the full range of problems resulting from
          implementation errors or an unreliable connection.  Mail
          delivery protocol issues may be controlled by many parties
          including the originating system, destination system, or
          intermediate system administrators.

       X.6.X   Message Content or Media Status

          The message content or media status codes report failures
          involving the content of the message.  These codes report
          failures due to translation, transcoding, or otherwise
          unsupported message media.  Message content or media issues
          are under the control of both the sender and the receiver,
          both of whom must support a common set of supported
          content-types.

       X.7.X   Security or Policy Status

          The security or policy status codes report failures
          involving policies such as per-recipient or per-host
          filtering and cryptographic operations.  Security and policy
          status issues are assumed to be under the control of either
          or both the sender and recipient.  Both the sender and
          recipient must permit the exchange of messages and arrange
          the exchange of necessary keys and certificates for
          cryptographic operations.


       X.0.0     Other undefined Status

          Other undefined status is the only undefined error code. It
          should be used for all errors for which only the class of the
          error is known.



       X.1.0     Other address status
       X.1.1     Bad destination mailbox address
       X.1.2     Bad destination system address
       X.1.3     Bad destination mailbox address syntax
       X.1.4     Destination mailbox address ambiguous
       X.1.5     Destination mailbox address valid
       X.1.6     Mailbox has moved
       X.1.7     Bad sender's mailbox address syntax
       X.1.8     Bad sender's system address

       X.2.0     Other or undefined mailbox status
       X.2.1     Mailbox disabled, not accepting messages
       X.2.2     Mailbox full
       X.2.3     Message length exceeds administrative limit.
       X.2.4     Mailing list expansion problem

       X.3.0     Other or undefined mail system status
       X.3.1     Mail system full
       X.3.2     System not accepting network messages
       X.3.3     System not capable of selected features
       X.3.4     Message too big for system

       X.4.0     Other or undefined network or routing status
       X.4.1     No answer from host
       X.4.2     Bad connection
       X.4.3     Routing server failure
       X.4.4     Unable to route
       X.4.5     Network congestion
       X.4.6     Routing loop detected
       X.4.7     Delivery time expired

       X.5.0     Other or undefined protocol status
       X.5.1     Invalid command
       X.5.2     Syntax error
       X.5.3     Too many recipients
       X.5.4     Invalid command arguments
       X.5.5     Wrong protocol version

       X.6.0     Other or undefined media error
       X.6.1     Media not supported
       X.6.2     Conversion required and prohibited
       X.6.3     Conversion required but not supported
       X.6.4     Conversion with loss performed
       X.6.5     Conversion failed

       X.7.0     Other or undefined security status
       X.7.1     Delivery not authorized, message refused
       X.7.2     Mailing list expansion prohibited
       X.7.3     Security conversion required but not possible
       X.7.4     Security features not supported

Image[:ask] According to default installation of Windows, the default keyboard layout (generally US - QWERTY) is used on login authenticaton screen. So how to change the default keyboard layout to my layout like french AZERTY or Swiss QWERTZ keyboard layout under Windows 2000 or XP.

[:idea] You need to change the keyboard layout of the default account to match the layout you do use.

Procedure:

This is correct to say that once you login to a system you can set what keyboard to use, but at logon time, the default selected keyboard is the same as the default keyboard layout that was chosen during the setup of Windows 2000/XP (in your case English–US).

For Windows 2000 there isn't any system settings you can change to add more keyboards for the logon dialog, but there is a workaround for those who have administrator rights to the computer. Here it is:

  • First add the keyboard layout you wanted to the your current user (open "Settings=>Control Panel=>Regional Options" and add a keyboard layout)
  • Open "regedit" in HKCU\Keyboard Layout\Preload
  • Look for the key you added
  • Create the same key value in HKU\.DEFAULT\Keyboard Layout\Preload
  • You will also need to replicate, the "Substitutes" folder.

Once you have set this up, you can select a different input locale in the logon dialog by:

1.Press the "Options >>" button. This will allow you to see the input locale in a blue rectangle.
2. Use <Right Alt>+<Shift> to toggle between the different installed input locales.

Now the good news is that Windows XP will make all this much simpler. The way you are able to do this is the following:

  • Open the "Regional and Language Options" in the Control Panel and go to the "Language" tag
  • Click the "Details" button and add all the keyboards you want to use in the logon window.
  • Go to the "Advanced Options" tag in the regional and language option.
  • Check the check box under "Default user account settings" (The system then applies all the settings of the current user account to the default user profile.)

Now when you go to the logon dialog do the same as mentioned above with the <Right Alt>+<Shift> key combination to toggle through the available keyboards.
