    Since it should be equal to “C as high a long the recent trend of the ISOs standards relating to automotive parts, this trend was introduced in the parts enclosed with so as to be able to be applied, should it be essentially required. Exponential function type decaying positive polarity transient voltage Type B and Type E: Any equipment installed on body or the spring of suspension system, the vibration of which is relatively high.

    Although these test apparatuses are desirable to be used in low temperature atmosphere, they may be used under room temperature if it is considered acceptable according to the agreement between the persons concerned. However, since the JIS C was abolished after the JIS C and C coordinated with IEC and had been enacted, it was decided to review the standards and code to be referred therein and to describe the operations required of the test concretely.

    Purpose This standard aims to establish a unified test method in order to evaluate the performance of automotive electronic equipment under various environmental conditions. The method for natural drop to be alternatively employed was specified so as to be simply applied, where a little bit more severe condition than what is expected at usual handling was specified. I btl Measureing instrument Loading Input device where, Low frequency oscillar: A transient voltage will occur when Si is turned off.

    JASO D possible. The class 3 carry out according to necessary condition. Test apparatus and sait water. Therefore, the time required of release was specified so as to be equal to 10 minutes to the maximum value as long after such maximum value on the condition at normal room temperature and under normal room humidity had been decked to be used.

    Limits between 29 and 59 volts per meter are still very difficult to test unless the sample is small and parallel plates could be used. According to the previous provision, a resistance of 2 ohms or diode had been required to be inserted in the transient voltage generating circuit of the power supply system between the power source and the test specimen.

    Ammeter The accuracy shall be in class equal to or higher than 0. A power supply device, input device s and loading device. Because it is not favourable for the voltage from the power supply device to d0019-4 widely fluctuated due to operation of the equipment during test, the allowable range of such fluctuation has been revised so jazo to be a little bit severer. Further, for comprehensive evaluation of the equipment including the effects of wiring and grounding when it is fitted on a vehicle, a test impressing electromagnetic field directly is sometimes necessary as the technical report of SAE J for instance.

    Capacity 15OpF of the capacitor C and value of resistance R are specified based on the electrostatic discharge equivalent circuit of the human body and conformity with IS0 standard. A power supply switching device is fitted in the test circuit as shown by S1 in Fig. Following two kinds of constant temperature chamber; 1 Low constand temperature chamber The inside temperature can be controlled so as to be kept at temperature within a range Of – 5 I 2 ” C. From a reason that it is better to be optionally combined by user subject to the basic requirements for testing having been set out, such opinion was not accepted.

    Measured values around transmitting station or upon transmitting of transceiver include those obtained through combination of measuring conditions of distance and received polarized wave, etc.

    Of load dampings, A-1 and D-1 are the tests for transient voltages caused by the delayed response in field coil. Lower the temperature inside the chamber gradC ually, when it has reached to – 30 Okeep the equipment for 1 -t 0. Setting temperature shall be as shown in Table After the test above, the test in 5. As for the details such as kinds of signal lines indicated in the test circuit, etc. Of load dampings, A-2 and D-2 are the tests for transient voltages caused by the inverse electromotive force of the stator coil.

    L L ;c: This standard is desirable to be applied to motorcycles, if possible, although the environmental conditions of motorcycles are not always the same as four wheelers. Impressing may be done not only between the earth terminal and all other terminals but also, if necessary, between each terminal and the case, and in particular case test conditions test voltage, applying period, number Equipment subject to electrostatic test Although kinds of equipment subject to Type A through Type C electrostatic tests are basically left to the agreement between the perties concerned, some examples are given in Explanatory Table 2 for reference taking account of the degree of effects on the vehicle when the equipment have occurred abnormalities.

    Progressed with a great variety of electronic devices in recent years, such equipments have increased that give and receive information with drivers through switches, keyboards or visual displays. Particularly the impressing direction of electric field, the fitting direction of the test specimen for instance, the surface to be faced toward the ground of a specimen shall be faced to the outer conductive surface of the TEM celletc.

    The voltage, however, will be kept at about 18V while the electrolyte remains. In case of the equipment, the heat mass of which are utmost high, the duration of time for holding at low temperature and the time required of release in constant temperature and humidity chamber may be optionally fixed in accordance with the agreement made between the persons concerned. In respect of method of treatment for measurement of performance after the temperature and humidity cycle test, the three conditions as listed hereunder were specified.: Further, carry out the test pattern specified in Fig.

    The test conditions are specified through practical measurements of the transient voltage of each inductive load, and relatively large transient voltages among these measurements are given as typical values. Take the specimen out of the chamber, remove water drops from its surface, if any, then keep it for 2 hours or more under room temperature, test it according jaao 5.

    Take the test specimen out of the chamber and keep it for 2 hours or more under room temperature, test it according to 5. Upper portion of the instrument panel: Herein this paragraph, the matters in respect of general requirements and major points of revisions on this time are explained. It is considered not necessary for the equipment to be installed inside car room to be immmersed in oil.

    TypeCandTypeF of above classified various transient voltages, the tests cover 5 ;that is, the resistance against d001-994 interference caused by inductive and capacitive combination between loading lines that are loaded in an operation of naso, radiated electric noise interference from d0019-4 magnetic inductive interference caused by alternator, ignition systems high tension codes, spark plug etc.

    The test shall be carried out for following equipments: In addition, grounding of whole test devices is necessary in order to the stabilization of reference potential and the safety during tests.

    Clocks, navigation device, etc. However, voltages that are induced and impressed by transient voltages and electro-magnetic disturbances are not jawo. In the necessary case, the testing conditions severity of the shock, height of drop, etc. Impression duration for applying electromagnetic d001-994 factors and other test conditions conditions that may affect on troubles according to the modulation method for interfering electromagnetic waves, degree of modulation, modulation frequency, etc, and other environmental conditions are not particularly specified in this standard, but it is recommendable to carry out the tests by selecting appropriate test maso and conditions which best fit to each object.

    Equipment installed outside the vehicle other than class 4. It would be difficult to get test gear. Further, measuring accuracy and reproducibility of TEM cell test method using the reference sample, that careful consideration is necessary on the following points:
