Q: What is the meaning of IP67?
A: IEC60529 and EN60034-5 (=IEC60034-5) classify the dust-resistance and waterproofing into grades.
The IP (ingress protection) rating represents the degree of protection for "dust" and water. The firstnumber following the "IP" refers to the degree of protection against access to hazardous parts and solidforeign objects (dust). The second number refers to the degree of protection against the ingress ofwater. The test methods are shown below.

An "X" is used when one of the two protection classes is not specified in the name (e.g. IPX5 or IP4X)

First Number = Degree of Protection against access to hazardous parts and against
solid foreign objects

IP Explanation and Ratings
EN 60529 outlines an international classification system for the sealing effectiveness of enclosuresof 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 thedigits if there is only one class of protection; i.e. IPX4 which addresses moisture resistance only.)__________________________________________________________________________________________All correspondence to:Temprecord International Limited

Degrees of Protection - First Digit
The first digit of the IP code indicates the degree that persons are protected against contact withmoving parts (other than smooth rotating shafts, etc.) and the degree that equipment is protectedagainst solid foreign bodies intruding into an enclosure.
0123456No special protection
Protection from a large part of the body such as a hand (but no protection fromdeliberate access); from solid objects greater than 50mm in diameter.
Protection against fingers or other object not greater than 80mm in length and 12mm indiameter.
Protection from entry by tools, wires, etc., with a diameter of thickness greater than1.0mm.
Protection from entry by solid objects with a diameter or thickness greater than 1.0mm
Protection from the amount of dust that would interfere with the operation of theequipment.
Dust tight.

Degrees of Protection - Second Digit
The second digit indicates the degree of protection of the equipment inside the enclosure against
the harmful entry of various forms of moisture (e.g. dripping, spraying, submersion, etc.)
012345678

No special protection
Protection from dripping water.
Protection from vertically dripping water.
Protection from sprayed water.
Protection from splashed water.
Protection from water projected from a nozzle
Protection against heavy seas, or powerful jets of water.
Protection against immersion.
Protection against complete, continuous submersion in water.

Submersion depth and time must be specified by the end-user. The requirement must be more
onerous than IP67
The IP Code Symbols
The chart at the right illustrates the use of special symbols in the IP classification system. In the"1st digit" column, not the grid-like symbols net to numbers 5 and 6. In the "2nd digit" column
numbers 3-8 are symbolised by teardrop shaped symbols, sometimes enclosed in a box or atriangle, sometimes unenclosed (#7-8). These symbols can be placed on equipment to illustrate
the IP protection provided.
