IP level test

The degree of protection classifies electrical appliances according to their protection against dust and moisture. The protection level is composed of two numbers. The first number indicates the degree of dust separation of the electrical appliance to prevent the intrusion of foreign objects. The second number indicates the degree of sealing of the electrical appliance against moisture and waterproof intrusion. The larger the number, the higher the protection level. Certification is preceded by a voluntary factory inspection in accordance with the European Electrotechnical Standards Committee. Level certification can be carried out according to customer requirements. The required materials are two samples, product instructions, and circuit diagrams. The issuance cycle is about one working day.
Definition of level dustproof and waterproof

The first indication of dustproof level
No protection
Prevention against the intrusion of large solid bodies
Prevention against the intrusion of medium-sized solid bodies Intrusion of small solids
Prevents the entry of solid objects larger than the size. Prevents the accumulation of harmful dust. Completely prevents the entry of dust. No protection. When the casing is tilted to a certain angle, water droplets dripping into the casing will have no effect. Water or rainwater will flow from corners to the casing and will have no impact. Liquids splashed onto the casing from any direction will have no harm. Rinse with water without any harm. Can be used in the environment inside the cabin
It can withstand water immersion in a short period of time and can withstand water immersion for a long time under a certain pressure. The international protection standard is a term defined by and. These standards give a classification of the degree of protection of electrical equipment enclosures when the rated voltage is not exceeded. The specific content is as follows personal protection.
Protection of electrical equipment to prevent the entry of solid substances including dust. Protection of electrical equipment from water damage to equipment.
Code Explanation
A code consists of letters and two numbers. The first number is ~, the second number is ~ or
〉> Soaking in water from centimeters to meters deep for minutes can prevent water from entering. 〉〉 Under the conditions specified by the supplier, continuous immersion in water can prevent the entry of water.
〉Able to withstand the hot steam washout test defined in This provides protection against water pressure and temperature. Pressure is applied directly to the sensor, in increments of degrees, and degrees, for seconds at each angle, for a total of seconds and minutes, preventing the ingress of water.
These protection levels are often not understood correctly or applied incorrectly. For example, many users believe that the level of protection allows the device to operate normally while being submerged in water for a specified period of time. This is not the case. These protection levels only ensure that the device can still operate normally after it is removed from the water.
Another possible misunderstanding is that satisfying means automatically satisfying and. In fact, it can only protect against scouring pressure and is not suitable for applications immersed in water. Therefore, protection levels are often used in applications that are subject to frequent cleaning and washout, such as breweries, car washes and food and beverage plants, but are not suitable for use in situations where the equipment is completely submerged in water.
