In modern life, electronic devices have become an indispensable part of our daily life. However, in harsh environmental conditions, dust, water, oil and other factors may cause damage to the equipment, affecting its service life and performance. To address these challenges, the International Electrotechnical Commission (IEC) has developed the IP Protection Rating standard for assessing the protection of electrical equipment against solid foreign objects and liquid intrusion.

"IP protection level" consists of two numbers, the first number indicates the dust level, the second number indicates the waterproof level, the larger the number, the stronger the protection ability.

Dust class:

0: No dust protection

IP1X: prevents the invasion of solid foreign bodies with a diameter greater than 50mm

IP2X: Prevents the invasion of solid foreign bodies larger than 12.5mm in diameter

IP3X: prevents the invasion of solid foreign bodies larger than 2.5mm in diameter

IP4X: Prevents the invasion of solid foreign bodies larger than 1mm in diameter

IP5X: Prevents dust intrusion

IP6X: completely dust proof

Waterproofing grade：

0: No waterproof protection

IPX1: prevents vertical dripping

IPX2: Prevents dripping within 15° of tilt

IPX3: prevent water from spraying

IPX4: Prevents splashing of water

IPX5: Prevent low pressure water column (within 3 minutes, 12.5cm from the nozzle, spray with a φ12.5mm water column at 30° tilt)

IPX6: Prevents strong spray of water

IPX7: Prevent temporary flooding (no more than 1m depth, no more than 30 minutes)

IPX8: Protection against long-term flooding (depth of more than 1m)

IPX9K: Prevent high temperature and high pressure water column (10cm from the nozzle, spray with 80°C hot water at a flow rate of 17.5L/min for 15 minutes)

"IP Protection Level" has a wide range of applications in various fields, such as:

Industrial control equipment：

It usually works under harsh environmental conditions such as dust, oil, high temperature, and high humidity, so it is necessary to select equipment with a high IP protection level to ensure its normal operation.

Household appliances：

Such as washing machines, air conditioners, etc., also need to consider dust and waterproof performance, such as washing machines need to prevent water splashing, and air conditioners need to prevent dust from entering.

Outdoor lighting：

Long-term exposure to wind and rain requires the selection of equipment with a high IP protection rating to ensure its durability.

Automatic Sprinklers

For example, IP65 means that the device is completely dust-proof and can protect against low-pressure jet water from any direction.
