How many levels of building waterproofing are there? How are the waterproof levels divided

The code divides buildings into four categories as follows:

A type of building is a building of special importance, such as a museum, a library, a memorial hall, an exhibition hall, a file gallery, and a laboratory of special importance.

Waterproof durability 25;Waterproof fortification requirements: three or more fortifications.

Category II buildings are important buildings. Such as terminals.

Station terminals, star-rated hotels, theaters, hospitals, shopping malls, and warehouses for storing important materials. Waterproof durability 15;Waterproof fortification requirements: two fortifications.

The three types of buildings are ordinary industrial and civil buildings. Such as office buildings, residences, industrial plants, school buildings and general warehouses. Waterproof durability 10;Waterproof fortification requirements: a fortification.

Most of the four types of buildings are buildings that need to be demolished in three or five years or have very low requirements for waterproofing. Such as sheds, building parts processing sheds, car and bicycle sheds, warehouses, etc. Waterproof durability 5;Waterproof fortification requirements: a fortification.

Waterproof Rating IP0 Waterproof Rating IP9.

The waterproof rating IP1,1 means that the droplets falling vertically in the drip-proof Type I have no harmful effects. Waterproof grade IP2,2 drip proof type with no harmful effects on water droplets falling within 15 degrees of the vertical direction. Waterproof grade: IP3,3 rainproof type, and the vertical direction within 60 degrees of rain without harmful effects.

Waterproof IP4,4 splash-proof type is protected from water splashes in any direction and has no harmful effects. Waterproof class IP5,5 anti-jet type, directly subject to water jetting in any direction, without harmful effects. Waterproof class IP6,6 waterproof type, no direct water jet from any direction will enter the interior.

Waterproof class IP7,7 immersion resistant type does not enter the interior even if immersed in water under specified conditions.

Introduction to waterproof ratings

Waterproof grade: The level of waterproof protection function, including building waterproof grade, instrument waterproof and dustproof grade. It is mainly determined according to the nature, importance, functional requirements of the building, the characteristics of the building structure and the durability of the waterproof layer.

The waterproof grade of the building should be determined by the designer in the waterproof design, according to the nature of the building, the degree of importance, the use of functional requirements and other acres to determine the waterproof grade of each part of the building. Then, according to the waterproof grade and the durability of the waterproof layer, the waterproof material is selected and the structure design is carried out.

The waterproof level of the electronic measuring instrument reflects the moisture-proof and dust-proof ability of the instrument, especially for outdoor activities, inevitably in the harsh environment of high humidity or dusty pants Bidong sand, the sealing and waterproof ability of the instrument is very important to ensure the safe operation and life of the instrument.

The above content reference: Encyclopedia - waterproof level.

IPX waterproof is divided into 9 levels:

ipx1、ipx2、ipx3、ipx4、ipx5、ipx7、ipx8、ipx9k

The larger the number behind, the higher the level of waterproofing, and the test chamber of different levels of the anti-beam water grade regret hail car, **.

The level of waterproof protection function of the anti-ruler draft water grade, including the waterproof grade of the building, the waterproof and dustproof grade of the instrument, is mainly determined according to the nature, importance, functional requirements of the building, the characteristics of the building structure and the durability of the waterproof layer.

The following situations are comprehensively considered when dividing the waterproof level: the imitation cavity will cause huge losses after leakage, up to the personal **; Leakage can cause significant economic losses; After leakage, it will cause general economic losses; After leakage, it will affect the appearance.

The waterproof grade of the building should be determined by the designer in the waterproof design, according to the nature of the building, the degree of importance, the use of functional requirements, etc., to determine the waterproof grade of each part of the building, and then according to the waterproof grade, the waterproof layer durability to select waterproof materials.

Hello The waterproof level is divided according to the different degrees of the material's posture and tremor penetration under water pressure, which is usually stated by IP (protection level). The number at the beginning of the IP represents the level of protection of the product, the first number indicates the degree of protection against external objects, and the second number indicates the degree of protection against water. For example, IP67 means that the product has the function of sand and moisture-proof, the number 6 indicates that the product has the protection performance of small solid objects such as flying sand and dust, and the number 7 means that the product can withstand immersion in water within 30 minutes, but it should be noted that when using electronic production failures, especially when outdoor activities are required, appropriate protective measures should be taken to maintain its waterproof performance according to the specific situation.
