Simulate Rain, Splash, and Immersion Conditions to Validate Product Ingress Protection

Water ingress is a leading cause of product failure outdoors and in automotive and industrial applications — rain, splashing, high-pressure jets, and submersion can cause short circuits, corrosion, and permanent damage if an enclosure isn't properly sealed.

LIB waterproof testing solutions help manufacturers verify IP (Ingress Protection) ratings against water, from light splashing to full submersion, for products ranging from consumer electronics and automotive components to outdoor lighting, connectors, and industrial enclosures — reproducing dripping, spraying, jetting, and immersion conditions with precision.

With accurate water delivery systems, customizable test parameters, and complete after-sales support, LIB helps manufacturers worldwide validate product reliability and meet international IP rating standards.

Waterproof Testing Methods

Different products require different water exposure tests depending on their IP rating target, application, and industry standard.

LIB provides environmental simulation solutions for the following waterproof tests:

Dripping Water Test (IPX1 / IPX2)

Dripping water testing evaluates a product's resistance to vertically or slightly angled dripping water, simulating light condensation or dripping exposure.

Common standards:

· IEC 60529 (IPX1, IPX2)

Spraying Water Test (IPX3 / IPX4)

Spraying water testing evaluates a product's resistance to water sprayed at an angle or from any direction, simulating rain or splash exposure.

Common standards:

· IEC 60529 (IPX3, IPX4)

Water Jet Test (IPX5 / IPX6)

Water jet testing evaluates a product's resistance to low-pressure or powerful water jets directed from any angle, simulating hose-down or high-pressure washing conditions.

Common standards:

· IEC 60529 (IPX5, IPX6)

Immersion Test (IPX7 / IPX8)

Immersion testing evaluates a product's ability to withstand temporary or continuous submersion in water at specified depths and durations.

Common standards:

· IEC 60529 (IPX7, IPX8)

High-Pressure / High-Temperature Water Jet Test (IPX9K)

IPX9K testing evaluates a product's resistance to close-range, high-pressure, high-temperature water jets, commonly required for automotive and industrial washdown applications.

Common standards:

· IEC 60529

· ISO 20653

Rain Test

Rain testing simulates natural rainfall conditions to evaluate the water resistance of larger products or outdoor equipment under realistic weather exposure.

Common standards:

· IEC 60068-2-18

· MIL-STD-810H Method 506

Automotive Waterproof Test (JIS D0203)

JIS D0203 testing evaluates the water resistance of automotive electrical and electronic components under washing, splash, and spray conditions, and is widely required for automotive component approval in Japan.

Common standards:

· JIS D0203

GM Worldwide Ingress Protection Test (GMW16001)

GMW16001 testing verifies the dust and water ingress protection performance of automotive electrical and electronic components in line with General Motors global engineering requirements.

Common standards:

· GMW16001

Enclosure Type Rating Test (UL50E)

UL50E testing evaluates the environmental protection performance of electrical equipment enclosures, verifying Type ratings against rain, dust, splash, and water exposure for indoor and outdoor use.

Common standards:

· UL50E

Waterproof Testing Equipment Selection Guide

Choosing the correct waterproof test chamber depends on: Required IP rating, water pressure and flow rate, sample size, immersion depth and duration, test standard, industry application, and test duration.

LIB provides different waterproof simulation chambers to meet various testing requirements.

Customer Success Case: Complete IP Waterproof Testing Laboratory Solution

In 2019, a South Korean testing agency required a complete IP testing solution to expand its product testing services.

Instead of a single testing machine, LIB provided a customized IP laboratory solution covering:

· IPX1–IPX9K waterproof testing

· IP5X/IP6X dustproof testing

LIB supported the complete process, including equipment configuration, installation, and technical guidance.

With LIB’s complete IP testing solutions, Standard Bank established a professional waterproof and dustproof testing capability to serve different customer requirements.

LIB also provides long-term technical support and regular equipment calibration assistance to ensure accurate and reliable testing results.
