JIS D 0203 testing

Test JIS D 0203, essai d'étanchéité à l'eau, humidité, pluie, pulvérisation, immersion

Our testing laboratory carries out JIS D 0203 testing to evaluate the moisture and water resistance of automotive parts according to Japanese industrial standards.

What is JIS D 0203 ?

JIS-D-0203 is a Japanese standard that defines test methods for evaluating the moisture and water resistance of automotive components. It is essential to ensure the performance and durability of parts exposed to the elements.

Why are JIS-D-0203 tests important ?

  • Safety: Automotive components must be water-resistant to prevent short circuits, malfunctions, and accident risks.
  • Reliability: Good sealing ensures a longer component life and reduces maintenance costs.
  • Regulatory compliance: JIS-D-0203 testing is often required to obtain certifications necessary for marketing vehicles.

JIS-D-0203 sealing tests

JIS-D-0203 covers several types of tests, including water spray, immersion and condensation tests.

JIS-D-0203 testing applies to a wide range of automotive components, such as: taillights, headlights, battery compartments, electrical connectors and control modules.

    Moisture test

    • M1 – Test to investigate the function of the parts subjected to moisture.
    • M2 – Test to investigate the function of the parts subjected to high temperature and humidity.

    Rain test

    • R1 – Test to investigate the function of the parts subjected to droplets .
    • R2 – Test to investigate the function of the parts subjected to indirect wind and rain or spray.

    Spray test

    • S1 – Test to investigate the function of the parts subjected to direct wind and rain or spray.
    • S2 – Test to investigate the function of the parts subjected to heavy water spray.

    Dip test

    • D1 – The test to investigate the function of the parts subjected to occasional water immersion.
    • D2 – Test to investigate the function of the parts continually subjected to water immersion or of the parts designed to be completely waterproof.
    • D3 – Test to investigate the function of the waterproof parts of special applitation.

    The 6NAPSE Group testing laboratory has extensive experience in carrying out water and moisture tightness tests according to the protection index (IP).
