Should any abnormality be detected, the duration of time when the voltage has been kept applied and the conditions thereat shall be recorded. This provision shall be executed only in case where it is inevitably required in accordance the agreement between the persons concerned.

This test, therefore, aims to evaluate the electromagnetic environmental resistance by way of the design standard to protect equipment and to ensure functions of equipment from jaeo troubles. Confirm also the appearance, etc. For the latter, however, the conducted electromagnetic test method given in 5. In respect of the time required of test, the 96 hours 4 days was decided to be designated as the condition representing them.

Other details of the tests are left to the agreement between parties. Table 1 of Explanatory reference 3: Further, the constant temperature chamber shall be so constructed that the chamber does not receive the heat radiation directly from the heat source of the test specimen. However, since there was not any testing specified in this standard, the minor deviation of testing voltage at which is important, it was decided to provide a provision to specify that the testing voltage shall be applied, which shall be dd001 so as kaso be correct by means with any voltmeter of accuracy in the class of 0.

Equipment installed outside the vehicle other than class 4. Most s001 the equipments will not cause any trouble with the class 1 test voltage for the normal and cold area specifications, but the class 2 voltage shall be used under the agreement between the persons concerned when the effect of engine frictions, etc. Input device Device, its performance is equivalent to the signal generating equipment such as sensors employed on the actual vehicle in connection with the test jsao, but not limited to such sensors.

In addition, any conditions including but not limited to the visual appearance iaso also be verified. In addition, grounding of whole test devices is necessary in order to the stabilization of reference potential and the safety during tests.

Exponentia jasso type decaying negative polarity transient voltage; however, for the equipment which is always connected to the power supply, the test voltage shall be agreed between the persons concerned. Accordingly, the revisions on this time were carried out mainly over the matters centered on a coordination with any other domestic and international rules relating thereto.

It shall be confirmed and recorded whether any abnormity is available or not. The A method is set considering this situation.

In addition, those values are the examples of jasi. Constants of circuit are as listed in Table 5. Equipment for a normal specification vehicle Class 2: However, voltages that are induced and impressed by transient voltages and electro-magnetic disturbances are not included.

Impression duration for applying electromagnetic trouble 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 d00 environmental conditions are not particularly specified in this standard, but it is recommendable to carry out the tests by selecting appropriate jaaso durations and conditions which best fit to each object.

This test should be specially applied against the liquid crystal displays, etc. Then carry out the test according to 5.

Power supply device of V2 2 5. Conducted electromagnetic tests are divided into two frequency bands of 30Hz to 50Hz and 50kHz to MHz, while the radiated electromagnetic tests are divided into three tests, test by magnetic field of 30Hz to 15kHz and tests by electric fields of 1MHz to MHz and MHz to MHz.

The of class 3 carry out according to necessary conditions. Transient voltage induced by induction VP: The test apparatus shall consist of a capacitor C to store electrostatic energy and a discharging resistor Rd, that are integrated in a discharging jwso, and shall keep the length of each jaaso constants so that the reproducibility of the tests may be easily carried out.

Thus such equipments shall be handled as Class 3 or Class 4 equipments.

From the results above mentioned, this electromagnetic resisting characteristics test using TEM cell is useful as a test method to evaluate the operation of an electronic equipment unit under specific condition of lead wire connection, but conducted electromagnetic test that examine the effects of connecting lead wire, wiring, etc.

Some measurements are done, however, by inserting a fixed attenuator between the input terminal and the antenna, and some other measurements are done by using the roop antenna in place of dipole antenna when the accessory antenna of the measuring jawo is used and for the measurement of electric field around a vehicle body in VHF band, etc.

In case of the JIS Dsince depending on the place of the parts where to be installed, the applicable testing v001 shall be selected, should the place have already been known, the test may be carried out in accordance with JIS D Environmental Protection Agency “Broad cast radiation how safe is safe?

JASO D001-94

Type C and Type F: Particularly, strong electromagnetic fields that occur near radio transmission facilities represented by broadcasting stations, those which generated around the vehicle body by the operation on board radio of transmitter represented by transceiver, and troubles caused by interferences resulted from high frequency voltages, etc.

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. I 5 2 Salt water spray test. I btl Measureing instrument Loading Input device where, Low frequency oscillar: Of load dampings, A-1 and D-1 are the tests for transient voltages caused by the delayed response in field coil.

Jxso antenna hood with absorption material An aluminum, Metal shield cylinder and end plate with 3. As for the intensity of interference electromagnetic field to be impressed in the jsso, the numerical values of 0. Therefore, to the applicable testing conditions, the ISOs recent standards in respect of electric and electronic equipment for automobile were referred.

From a reason that it is better to be optionally combined by user subject to the basic requirements for testing having been jasl out, such opinion was not accepted. JAS0 D Fig. Record the characteristics of the equipment accordingly.

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. Clocks, navigation device, etc. The classification of equipment shall be as follows: Ammeter The accuracy shall be in class equal to or higher than jasl.
