IP68 is not the highest level of protection?
What is the protection level?
The so-called protection level in Italy refers to the classification of different degrees that can prevent the penetration of dust and moisture.
Our common water pump protection registration is usually a mark such as IP55 or IP68. This marking method is derived from IEC60529 or GB/T4208.
What does IP mean?
IP is the acronym for INGRESS PROTECTION, used to represent the two capabilities of electromechanical products for dust and water resistance.
The traditional IP rating consists of two digits.
The format is IP__ __.
The first digit marks the dustproof level, which means the level of preventing solid foreign objects from entering, and is divided into 7 levels from 0-6.
Pumps with lower protection levels are usually ordinary household products, which may be IP44, because the design and installation environment of the pump will not have too many hidden dangers, or the characteristics of the pump are not suitable for higher protection upgrades.
Conventional civil dry-mounted water pumps are usually IP54 or IP55, which is mainly determined by the motor type.
The second number marks the waterproof level, indicating the waterproof ability, which is divided into 9 levels from 0-8.
IEC60529 updated a version of the standard in 2013, and GB/T4208 was also updated once in 2017. After the update, the waterproof level has changed from 0-8 to 0-9, which means that there are 10 waterproof levels. The 9 stands for protection against high temperature and high pressure water spray.
The difference between IP and IPX
IPX is an international general waterproof level certification system. It is used to mark the waterproof level of products on many instruments and equipment. It is the most common technical indicator.
Each IP waterproof level test standard is different. We often see labeling grades such as IPX8. This label means that there is no restriction on the dustproof level, and no restriction does not mean that there is no dustproof ability.
