Dust test
Project Introduction
For portable, outdoor, and automotive electronics, there are dust test requirements. Both IEC, MIL, ETSI, and SAE have internationally developed test requirements. Test methods for the testing of electrical and electronic products, automotive and motorcycle parts, and seals to prevent sand dust from entering the seals and enclosures in a sand-dust environment, and to determine the effects of suspended dust in the air on the product.
IEC/EN60529 is classified into 7 levels of dust (level 0 ~ level 6) and dust level (e.g. IP5X - dust level 5)
Level 0: No dust protection at all
Level 1: It can protect foreign objects with a diameter greater than 50mm from falling into the device
Level 2: Protects against foreign objects with a diameter greater than 12.5mm falling into the device
Level 3: Protects foreign objects with a diameter greater than 2.5mm from falling into the device
Level 4: It can protect foreign objects with diameter greater than 1.00mm from falling into the device
Level 5: The dust cannot be completely prevented from entering, but the amount of dust entering must not affect the normal operation of the equipment and must not affect the safety.
Level 6: Completely dustproof
Waterproof test
Project Introduction
There are waterproof test requirements for portable, outdoor, and automotive electronics. Internationally, both IEC, MIL, or ETSI and SAE have developed corresponding test requirements.
IEC/EN60529 waterproof is divided into 9 levels (level 0 ~ level 8), waterproof level (e.g. IPX4 - waterproof level 4):
Level 0: Completely waterproof and unprotected
Level 1: Droplets in the vertical direction should have no harmful effects
Level 2: When the vertical surface of the shell is tilted within 15°, vertical drop should have no harmful effect
Level 3: Drenching water within 60° of each vertical plane without harmful effects
Level 4: Splashing water in all directions of the enclosure without harmful effects
Level 5: Spraying water in all directions of the enclosure without harmful effects
Level 6: Spraying water in all directions of the enclosure without harmful effects
Level 7: The amount of water in the enclosure will not reach the harmful level after immersing in the specified pressure for a specified time
Level 8: The influent water content of the enclosure will not be harmful if the conditions agreed between the manufacturer and the user (should be harsher than Level 7)
The IP rating system provides a method of classifying products against the dust, water and collision resistance of electrical equipment and packaging. This system has been approved by most European countries and is outside IEC 529 (BS EN 60529:1992). Announced in the IP code.
