Protective grade by IP code
Protective grade by IP code(JIS C 0920) IsJapanese Industrial StandardSpecified inwaterproofAnd defensedustGrade about the degree of.Consumer electronicsWhen "JIS protection grade" is described in product catalogs and manuals, it often refers to the grade related to waterproofing.In order to indicate this grade on products, etc., it must pass the test in accordance with the regulations.
2003/By the revision made inInternational Electrotechnical CommissionStandardized inEnclosure protection rating(Degrees of protection provided by enclosures (IP Code) / IEC 60529), And the provisions regarding the protection class that had been used before were deleted.However, since the old regulations are also formulated in accordance with the IEC regulations, they are generally the same, although there are differences in details such as inspection procedures.
IP codeIs a code of the specified protection class and the additional matters associated with it.International ProtectionIt is written in 4 to 6 characters starting with "IP" that represents.
For example, when "IP68" is described, the first characteristic number "6" indicates the protection grade against solid matter, and the second characteristic number "8" indicates the protection grade against water.If either protection class is omitted, enter "X". It should be noted that it is not "omitted = unprotected".
In some water protection grades, it is not possible to simply distinguish between the upper and lower inspection items, so it may be displayed as "IPX5 / IPX8" in the sense that it has passed multiple items.
Protection class against foreign solids
It is a protection grade for so-called "dustproof". Some solid matter will invade the inside except for the 6th grade.
|0 class||Not particularly protected|
|1 class||Solids with a diameter of 50 mm or more do not enter (assuming a fist level)|
|2 class||Solids with a diameter of 12.5 mm or more do not enter (assuming fingers)|
|3 class||Wires and solids with a diameter of 2.5 mm or more do not enter|
|4 class||Wires and solids with a diameter of 1 mm or more do not enter|
|5 class||Dust does not enter enough to cause harmful effects (dustproof type)|
|6 class||Dust does not enter (dust resistant type)|
Protection class against ingress of water
The index of waterproof performance is "IPXIt is represented by ". Originally, the third character following" IP "indicates the index of dustproof performance, but by putting" X "here, it indicates that it is not an index of dustproof performance, and as an index of waterproof performance. There is.
There are nine levels of resistance to water, from IPX0 to IPX8, where IPX9 represents no protection against water. From 0 to 0 each, the test method is specified by the standard. Since IPX7 only has a stipulation that "test conditions are stricter than IPX8" and there are no test conditions, IPX7 is actually a manufacturer's own standard.
From IPX0 to IPX6, some kind of internal inundation may occur, but it is not always inundated. On the contrary, even IPX7 and IPX8 only show waterproof performance as a standard, sudden failure, deterioration, operation It does not exclude the occurrence of accidents such as defects.
IPX7 and IPX8 only show waterproof performance against diving "in a state of being submerged in a certain amount of water", and are different from waterproof performance against strong short-time water pressure such as "jet water" implemented in IPX5 and IPX6. Is assumed.For this reason, two IP codes are often displayed side by side, such as "IPX5 / IPX7", to indicate the waterproof performance for each of the diving and jet..

|0 class||Not particularly protected|
|1 class||No harmful effects due to water droplets falling from the vertical (drip-proof type I)|
|2 class||No harmful effect due to water droplets falling in the range of 15 degrees from the vertical (drip-proof type II)|
|3 class||No harmful effects due to water droplets falling in the range of 60 degrees from the vertical (rainproof type)|
|4 class||No harmful effects from flying from all directions (preventive shape)|
|5 class||No harmful effects of jet water from all directions (jet-proof type)|
|6 class||No harmful effects from strong jet water from all directions (water resistant type)|
|7 class||Even if it is temporarily submerged under constant water pressure conditions, it will not be flooded inside (immersion-proof type).|
|8 class||Even if it is continuously submerged, it will not be flooded inside (underwater type)|
