Common IP ratings include IPX1 (protection against vertical water drops) up to IPX8 (protection against continuous submersion).
3. Importance of Waterproof Testing in Electrical and Electronic Products
Waterproof testing ensures that products can withstand exposure to water during their operation. This is critical for:
Safety: Prevents short circuits, electrical shocks, and equipment failures.
Reliability: Ensures consistent performance in wet or humid environments.
Durability: Enhances the lifespan of products exposed to harsh conditions.
4. Features of LISUN JL-X IP Waterproof Test Equipment
The LISUN JL-X series is specifically designed to meet international standards such as IEC 60529 and ISO 20653.

5.1 Testing Procedures
• IPX1 to IPX2 Tests: These tests involve dripping water onto the product at various angles to ensure basic protection against light rain or condensation.
• IPX3 to IPX4 Tests: Conducted using oscillating tubes or spray nozzles, these tests simulate exposure to water sprays and splashes, similar to rainstorms.
• IPX5 to IPX6 Tests: These involve the application of water jets at varying pressures to ensure the product can withstand powerful water impacts.
• IPX7 to IPX8 Tests: These submersion tests assess the product’s resistance to being submerged in water, crucial for devices used in marine or flood-prone environments.

What are the differences of FMVSS 302, UL94 and IEC60695 for flammability test?

Image
The flammability of different materials, such as plastics and other materials used in items such as automobile interiors, electronic devices, and electrical appliances, is evaluated using a number of different standards. Some of these standards are FMVSS 302, UL 94, and IEC 60695. Nevertheless, there are a number of important distinctions between these standards: FMVSS 302 is a specialized standard that was designed for the automotive industry to analyze the flammability of materials used in car interiors. Its purpose is to measure the combustibility of these materials. The UL 94 standard is a more comprehensive regulation that assesses the combustibility of a variety of materials, including plastics, and has applications in a number of different sectors. IEC 60695 is a global standard that is used in the process of assessing the potential for electronic and electrical equipment to catch fire. Testing Procedures The flammability of materials is determined using a variety of testing ...
