11、 bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organiza
12、tions, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in t
13、he ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of
14、 the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 16750-5 was prepared by Technical Committee ISO/TC 22, Road ve

17、and testing for electrical and electronic equipment Part 5: Chemical loads 1 Scope This part of ISO 16750 applies to electrical and electronical systems/components for road vehicles. This part of ISO 16750 describes the potential environmental stresses and specifies tests and requirements recommende
18、d for the specific mounting location on/in the road vehicle. This part of ISO 16750 describes chemical loads. It is not designed to evaluate whether an electrical/electronic system/component is suitable for performing during continuous contact with an agent, such as a fuel pump immersed continuously
19、 in fuel. NOTE Conditions and testing for a continuous contact can be determined from other standards or agreed upon between customer and supplier. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition
20、 cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

21、sting for electrical and electronic equipment Part 4: Climatic loads 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 16750-1 apply. 4 Tests 4.1 General Components and associated parts that can come into contact with the specified chemical agents shal
22、l be resistant to those agents. The components and associated parts shall be tested with all agents they are likely to come into contact with, except for those materials which can be shown by documentary evidence to be immune to the contaminant and which need not be tested. A material is considered
23、to be immune to a contaminant if there is no change in properties sufficient to affect material performances over the time and at the temperature specified in this clause. BS ISO 16750-5:2010ISO 16750-5:2010(E) 2 ISO 2010 All rights reservedManufacturer and type of chemical agents shall be agreed up
24、on between supplier and vehicle manufacturer. Resistance to the specified chemical agents shall be considered as early as during the material selection process. 4.2 Purpose The purpose of the test is to determine whether the device under test (DUT) is unacceptably affected by temporary exposure to c
25、ontaminating agents. NOTE This test is not intended to be a life test. 4.3 General test conditions Chemical agents shall be selected in accordance with Table 1, depending on the mounting location of the DUT. Unless otherwise specified, one DUT per test agent shall be used. The DUTs shall be tested w
26、ith all agents they are likely to come into contact with, except for those materials which can be shown by documentary evidence to be immune to the contaminant and which need not be tested. The following tests describe one test cycle. Unless otherwise specified, one test cycle with one agent per DUT
27、 shall be performed. Any other number of cycles may be agreed between customer and supplier. NOTE If the size of the DUT is sufficient, multiple test agents can be applied partially on one DUT if it is ensured that these do not have any influence on each other. 4.4 DUT conditioning Unless otherwise
28、specified, the DUT shall be stored at a room temperature (RT) of (23 5) C and a relative humidity (RH) of between 25 % and 75 % until temperature and humidity are stabilized. The DUT shall be tested under conditions of normal use. If necessary, and unless otherwise specified, unrepresentative coatin
29、gs or contaminations of the DUT shall be removed. If a cleaning procedure is needed, the methodology shall be agreed between customer and supplier. 4.5 Test agent conditioning Unless otherwise specified, all test agents shall be stabilized at an RT of (23 5) C when applied on the DUT. 4.6 Applicatio
30、n method Unless otherwise specified, application shall be performed at an RT of (23 5) C and an RH of between 45 % and 75 %. It shall be ensured by the choice of the application method that the DUT is sufficiently wetted by the test agent in the areas to be tested. The application method shall be ch
31、osen in accordance with Table 2, depending on the agent and the mounting location of the DUT. The preferred application methods are given in Table 1. 4.7 Test conditions Unless otherwise specified, the exposure of the DUT to the agent applied shall be performed at the temperature and for the duratio
32、n specified in Table 1.

44、 2) at RT. The DUT shall then be stored in a suitable chamber at the temperature and for the duration specified in Table 1. If required, the DUT shall be cooled down to RT after storage and tested as specified below. a) Perform a visual check and, if appropriate, a functional check and record data f
45、or comparison with post-test data. b) Condition the DUT (see 4.4). c) Place the DUT in its specified test setup. The configuration may include appropriate electrical or mechanical connections. BS ISO 16750-5:2010ISO 16750-5:2010(E) ISO 2010 All rights reserved 5d) Stabilize the temperature of the sp
46、ecified agent(s) (see 4.5). Apply the specified agent(s) in accordance with Table 1 and 4.6 to the surface of the DUT that is likely to be exposed. e) Allow the DUT to drain naturally. Shaking or wiping is not permitted. However, if representative of service conditions, it may be turned about any ax
47、is to allow for drainage from different positions. f) Maintain the DUT at the temperature and for the duration specified in Table 1. g) Stabilize the DUT at RT. h) For more than 1 cycle, repeat steps d) to g). i) Examine the DUT immediately in accordance with the requirements in 4.9. Any safety and
48、warning notes shall be observed. 4.9 Requirement The minimum functional status shall be class C in accordance with ISO 16750-1. If necessary, other requirements shall be agreed between customer and supplier. Marking and labelling shall remain visible and legible. 5 Documentation For documentation, t
