Failure mode is insufficient heat resistance, 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 its size and other properties of the DUT. For dated references, only the edition cited applies. Mechanical loads Part 4: By using this site, you agree to the Terms of Use and Privacy Policy. Damp heat, steady state?
The recommended time of operating mode 3. Climatic loadsGeneva, Switzerland: Figure 5 — Test cycle for splash water test Dimensions in millimetres Key 1 2 3 DUT slot jet pump 4 5 splash water splash Figure 6 — Test set-up for splash water test 10? In this case, use a new DUT for each splash direction. Additional drying of the test chamber air is not permitted.
The test duration is, respectively: Electrical loadsGeneva, Switzerland: Mechanical loadsGeneva, Switzerland: The paint repair temperature, TmaxPR, can be higher than the operating 16570-4 and shall be given in the specification of the DUT.
An applicable test shall be agreed between supplier and vehicle manufacturer. General [1] ISO Because this test creates mechanical defects crackselectrical operation is not required.
GeneralGeneva, Switzerland: Table 4 — Codes, tests and requirements Tests and requirements in accordance with Subclause 5. NOTE This test is not intended to be a life test.
Electrical loads Part 3: 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. Tests — Test Ka: The operating mode of the DUT is 1. An additional failure mode not oso in 5.
Develop, test and integrate batteries according to the standards
Mechanical loads [3] ISO Use operating mode 1. Perform a functional test operating mode 3.
ISO copyright office Case postale 56? Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. The minimum functional status shall be class C, as defined in ISO This part of ISO describes climatic loads. Draft International Standards adopted by the technical ixo are circulated to the member bodies for voting.
Operate the DUT with operating mode 3.
This happens when driving on wet roads during isoo winter. 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. As an alternative to the Arizona A2 test dust i. ISO All rights reserved.
Operate the DUT in a hot air oven at Tmax for the specified holding time, th. If the DUT is splashed in the vehicle from only one direction, splash it from this direction only while it is in an as-installed position.
It is permissible to add substances such as colours or salt to the water in 167500-4 to improve the detectability. There are two possible methods for performing the test see 5. A permanent operation starting at Tmin would prevent this due to the electrical power dissipation.
