There are two possible methods for performing the test see 5.

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.

The paint repair temperature, TmaxPR, can be higher than 167504 operating temperature and shall be given in the specification of the DUT. Damp heat, steady state? ISO — All rights reserved.

Mechanical loads Part 4: An additional failure isp not addressed in 5. Visual examination as detailed below shall allow identification, appearance, workmanship and finish of the item to be checked against the relevant specification.

Develop, test and integrate batteries according to the standards

End of temperature rise. Operate the DUT with operating mode 3.

Climatic loads [4] ISO IP-code see ISO Figure 7 — Test cycle for the salt spray test 5. If the equipment is splashed from various directions in the vehicle, then these directions shall be taken into account. The application of this test shall be stated in the specification of the DUT. Operate the DUT electrically functional test after the whole device has reached Tmin for the shortest possible duration in order to check the correct function of the device.


Failure modes are mechanical cracking of materials uso seal failures caused by different temperature expansion coefficients. International Organization for Standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

Failure mode is electrical malfunction caused by high temperature, e. The soak time can be agreed between customer and supplier, or the exposure time can be chosen among the values 20 min, 40 min, 60 min or 90 min, depending on 116750-4 size and other properties of the DUT. Other systems shall meet minimum functional status class C up to the last hour and class A for the last hour.

Road vehicles — Environmental conditions and testing for electrical and electronic equipment — Part 5: Failure modes are cracking of materials or seal failures caused by ageing and different temperature expansion coefficients.
