Many corporate customers are often confused about the anti-corrosion level, protection level, and explosion-proof certification level that their products need to meet.
Due to the fact that there is only a one word difference between the names, and they all refer to certain aspects of the product's level, which are similar yet different,
What are the differences between them?
Anti corrosion refers to the use of various methods to protect metal items that are prone to corrosion, in order to extend their service life. Usually, physical, chemical, and electrochemical methods are used for corrosion prevention. There are five common levels: indoor F1, F2, and outdoor WF, WF1, and WF2.
Protection level, commonly known as IP level, refers to the dust and water resistance level of the equipment, usually composed of IP and two digits.
Explosion proof level generally refers to the explosion-proof certification level of the equipment. Each electrical equipment applying for explosion-proof certification will have corresponding explosion-proof markings, including explosion-proof type and explosion-proof level. Explosion proof level refers to the explosion-proof area, gas/dust group, temperature group, equipment protection level, etc. that the product is suitable for.
It can be seen that these three belong to different concepts in different fields.
