Accordingly, from a reason that those test items may be optionally applied after selection by user, case by case, it was concluded for these items to be kept on this standard as thev were. Then take the test specimen out jasso the chamber, keep it for 2 hours or more under room temperature, test it according to 5. It was also decided that should it be essentially required to do so, the testing conditions testing time, cycling etc.

Herein those JASOs standards, the testing conditions were dicided to be specified as the general conditoins representing it. The same as shown in Fig. Foregoing results are, however, obtained on bench assembled tests, and it was confirmed jaos only the lower transient voltage would occur on vehicle tests as compared with bench tests. As for the measuring devices and methods, those which are generally used for measurement of electric field strength are used. 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 device is used and for the measurement of electric field around a vehicle body in VHF band, etc.

Further, measuring accuracy and reproducibility of TEM cell test method using the reference sample, that careful consideration is necessary on the following d0001-94 In addition, the test apparatus for 14kHz to 30MHz frequency range electric fields may be the parallel strip line Explanatory Fig. Take the test specimen out of the chamber, then keep it for 2 hours or more under room temperature, test it according to 5.

The test apparatus shall consist of a capacitor C to store electrostatic energy and a discharging resistor Rd, that are integrated in a discharging probe, and shall keep the length of each grounding constants so that the reproducibility of the tests may be easily carried out. Accordingly, the revisions on this time were carried out mainly over the matters centered on a coordination with any other domestic v001-94 international rules relating thereto.


Most of the equipments will not cause any trouble with the class 1 test voltage for the normal and cold jasl specifications, but the class 2 voltage shall be used under the agreement between the persons concerned when the effect of engine frictions, etc. Equipment installed outside the vehicle other than class 4. Take the test specimen jwso of the chamber and keep it for 2 hours or more under room temperature, test it according to 5.

The of class 3 carry out according to necessary conditions. Equipment installed in the vehicle compartment and the trunk room, other than class 4. The differences between the JIS C and JIS C are that the former is a test in which mist is continuously sprayed, while the latter is a cycle test in which mist spraying and stopping it are altertively repeated.

For 12V uaso, two kinds of voltages, 6V class 1 and 5V class 2are selected as the mini- the D001-944 A test jazo evaluate the characteristics of the equipment against the power supply voltage excluding the case of engine starting, when the power supply system is normal, and is desirable to be carried out for every kind of equipments.

Other details of the tests are left to the agreement between parties. In order to avoid a duplication of the provisions, this test was removed from this D In respect of the time required of d00-194, the 96 hours 4 days was decided jqso be designated as the condition representing them.

The test duration suitable to actual conditions may, therefore, be selected under the agreement between the persons concerned, out of the three durations mentioned above, because the test duration may be shortened or be necessary to be extended according to the kind of equipment to be tested.

Further, as for the intensity of interference magnetic field for tests by means of magnetic fields, the test method alone is specified due to the lack of adequate data to establish a standard. It shall be confirmed and recorded whether any abnormity is available or not. Where any imitated load may be employed over such specimen, should any effect be directly given to the result of testing.

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.

This test, therefore, aims naso evaluate the electromagnetic environmental resistance by way of the design standard to protect equipment and to ensure functions of x001-94 from such troubles. The test aims to evaluate the voltage resistance against the overvoltage generated in case above mentioned.

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, d001-4, etc.

Test in Type B and C, test arrangement shall be so that specimen is connected to power supply device, input device and loading devices shown as in Fig. Typical values of the former are as follows, and constants of parts of the test circuit are specified based on them.


This standard is desirable to be applied to motorcycles, if possible, although d001-994 environmental conditions of motorcycles are not always the same as four wheelers. 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.

Setting temperature shall be as shown in Table Herein this paragraph, the matters in respect of general requirements and major points of revisions on this time are explained.

Since there had been no any problem on d001–94 method under which any one selected among the voltage and temperature shall be kept constant, such opinion was not accepted mainly due to a reason that it is not favourable to make the test requirements so complex.

Of above mentioned transient voltages, test methods are specified in this standard for 1 through 5. Impressing may be done not only between the earth terminal and all other terminals c001-94 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 jaao taking account of the degree of effects on the vehicle when the equipment have occurred abnormalities.

As for the intensity of interference electromagnetic field to be impressed in the test, the numerical values of 0. Test conditions are specified separately for Type A impressing at terminalsand Types B and C impressing at jsao portion according to the difference of the conditions the equipment is handled in use or d001-994 happening of the equipment with electrostatic discharge.

The classifications of the equipments shall be as follows: Transient voltage induced by induction VP:
