Ingress Protection - IP classes of the housing of measurments

Protection classes according to EN 60529/ DIN 40050 / IEC 529 / VDE 0470

JAKO measuring instruments are designed and manufactured for the use in different environmental conditions. Standard measuring devices are mostly used in waterproof environments in buildings. Therefore, they do not need to meet any high safety requirements regarding the ingression of dust or water.

Other measuring instruments in light or heavy industrial designs, on the other hand, must meet the more or less heavy loads at the respective place of use (outdoors) and reliably function on a continuing basis. The enclosure sealing of these devices must, therefore, also meet more exacting requirements.

Which level of protection is met by JAKO products is specified in the respective JAKO product data sheets and JAKO information. The following is an explanation of the respective specified IP protection classes.

Protection against contact and against the ingress of foreign bodies as well as water

Protection classes are categorised according to EN 60 529. The protection classes are marked with internationally applicable abbreviations (IP = Ingress Protection). The abbreviation IP is followed by two digits. The first digit stands for the protection against the ingress of solid bodies. The second digit defines the degree of protection against the ingress of water. The information refers to untreated enclosures without consideration of influences such as ageing, temperature changes and the like.

EXAMPLE: What does the protection class IP 54 stand for?
First code digit = 5	= protection against dust and the access to hazardous parts with a wire
Second code digit = 4	= splash proof

The following table shows the respective level of protection!

Table: Protection classes according to EN 60529/ DIN 40,050 / IEC 529 / VDE 0470

Degrees of protection against contact and the ingress of foreign bodies			Degrees of protection against the ingress of water
First code digit	Scope of protection		Second code digit	Scope of protection
First code digit	Protection against	Explanation	Second code digit	Protextion agianst	Explanation
0	No protection		0	No protection
1	Large foreign bodies	Protection against accidental large-area contacting of active parts or parts in motion inside the equipment, e.g. with one’s hand, but no protection against deliberate access to these parts. Protection against the ingress of solid foreign bodies with a diameter larger than 50 mm	1	Vertically dripping water	Vertically dripping water must not have any damaging effects.
2	Medium sized foreign bodies	Protection against contacting active parts or parts in motion inside the equipment with one’s fingers. Protection against the ingress of solid foreign bodies with a diameter larger than 12 mm. .	2	Water dripping in any angle	up to 15° to the perpendicular must not have any damaging effects
3	Small foreign bodies	Protection against contacting active parts or parts in motion inside the equipment with tools, wires and the like with a Ø larger than 2.5 mm. Protection against the ingress of solid foreign bodies with a diameter larger than 2.5 mm	3	Spraying water falling in any angle	Spraying water falling in any angle up to 60° to the perpendicular must not have any damaging effects.
4	Granular foreign bodies	Protection against contacting active parts or parts in motion inside the equipment with tools, wires and the like with a Ø larger than 1 mm.	4	Splash water	Water splashing against the equipment from any direction must not have any damaging effects.
5	Dust deposit	Complete protection against contact with energised parts or parts in motion inside the equipment. Protection against harmful dust deposits. The ingress of dust is not completely prevented, but dust must not ingress in such quantities to affect the functioning.	5	Jet of water	A jet of water from a nozzle directed towards the equipment from any direction must not have any damaging effects.
6	Ingress of dust	Complete protection against contact with energised parts or parts in motion inside the equipment. Protection against ingress of dust.	6	Flooding	In the event of temporary flooding, e.g. as a result of choppy seas, the water must not enter at such a rate that it may cause damage.
			7	Dipping	Water must not enter at such a rate that it may cause damage if the equipment is dipped in water under the defined pressure/time conditions of 0.15 – 1 m.
			8	Immersion	Water must not enter at such a rate that it may cause damage if the equipment is immersed in water under the defined conditions.
			9	High pressure or steam jet cleaning	Water directed against the enclosure from any direction under high pressure must not have any damaging effects.
