The work of preparing International Standards is normally carried out through ISO technical committees. This third edition cancels and replaces the second edition ISO Upon agreement, this test may be performed during the development of a DUT with opened housing or without housing.

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. ISORoad vehicles—Environmental conditions and electrical testing for electrical and electronic equipment, is an ISO standard which provides guidance regarding environmental conditions commonly 167500-4 by electrical and electronic systems installed in automobiles.

Requirement For systems which are powered while the engine is shut off, functional status shall be class A, as defined in ISOfor the entire test duration.

Because this test creates mechanical defects crackselectrical operation is not required. Figure 16750- — Dewing test cycle 14?

General ISORoad vehicles — Environmental conditions and testing for electrical and electronic equipment — Part 2: With the device still operating, submerge it for 5 min in an ice water tank at least 10 mm deep. NOTE This test is not intended to be a life test.


Failure mode is electrical malfunction due to leakage currents caused by the ingress of salt water.

Table 4 — Codes, tests and requirements Tests and requirements in accordance with Subclause 5. Select a severity from Table 4 and Annex A.

Develop, test and integrate batteries according to the standards

Functional status class A is required in phases with electrical operation mode 3. In the vehicle environment, some equipment might experience different conditions regarding temperatures, temperature gradients and duration: Other systems shall meet minimum functional status class C up to the last hour and class A for the last hour.

If the DUTs to be splashed prove too big for one jet, arrange several jets in a row to produce a line of splash impact on the DUT. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. Use operating mode 3.
