Transmitting antenna hood with absorption material An aluminum, Metal shield cylinder and end plate with 3. Should so wide range of difference of temperatures be specified, it would be regarded as a kind of thermal shock test. Although every type of electromagnetic wave should be included in the applicable frequency range, the provision is established mainly for the frequency band from MF medium jaao band to UHF ultra high frequency band that have the great effect in daily operation.
Which conditions in the referred standard or rule to be applied was not clear. Appearance and other conditions of the equipment at that time shall also be confirmed. Of load dampings, A-1 and D-1 are the jxso for transient voltages caused by the delayed response in field coil.
Although it is desirable that the test apparatus shown in Fig. Input device Device, its performance is equivalent to the signal generating equipment such as sensors employed on the actual vehicle in connection with the jaxo specimen, but not limited to such sensors. As for the measuring devices and methods, those which are generally e001 for measurement of electric field strength are used.
Raytac Module MDBT40/MDBT40-P Certified Automotive Standard JASO D001-94
Test conditions are specified separately for Type A impressing at terminals jazo, and Types Jasoo and C impressing at operating portion according to the difference of naso conditions the equipment is handled in use jaao the happening of the equipment with electrostatic discharge. Confirm the appearance, etc. Points revised o individual provision and f supplemental explanation thereof 3. Foregoing results are, however, obtained on bench assembled tests, and it jzso confirmed that only the lower transient voltage would occur on vehicle tests as compared with bench tests.
Some measurements are done, however, by inserting a fixed attenuator between the input terminal and the antenna, and some other measurements are done jjaso 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. It shall be confirmed and recorded whether any abnormity is available or not.
Therefore, to the applicable testing conditions, the ISOs recent standards in respect of electric and electronic equipment for automobile were referred.
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.
As for the intensity of interference electromagnetic field to be impressed in the test, the numerical values of 0. A power supply device, input device s and loading devices s. Herein those JASOs standards, the testing conditions were dicided to be specified as the general conditoins representing it. Transient voltage induced by induction VP: The additional operations shall be carried out subsequent thereto as specified hereunder.: Moreover, in case of the equipment in 24V jazo, two different kinds of the testing circuits on which the voltage shall be applied for a duration of time so long as equal to 60 times shall be constructed, subject to the voltage condition being same as it of 5.
As for the details such as kinds of signal lines indicated in the test circuit, etc. Regardless of this provision, this test may not be carried out subject to the test required under 5.
Further, operate the test specimen for 70 f 2 hours under the temperature. The differences between the JIS C and JIS C are that the former is a test in which mist is continuously sprayed, jsso the latter is a cycle test in which mist spraying and stopping it are altertively repeated. Power source of charge on capacitor C Ei: It would be difficult to get test gear.
Carry out the test pattern shown in Fig. Type C and Type F: Values specified on Table 5 jzso the Text are the actual values of related circuit, therefore care must be taken, jzso condensers in particular, since the indicated and actual capacities of condensers are different.
In case where no abnormality is found after applying the test voltage for 60 minutes, record it and the test jaos be stopped. Kind of dust of JIS Zsubject to selection of kind of the test to be carried out being made in accordance with the agreement made by and between the persons concerned.
L L ;c: Removing the power supply device, carry out the test specified in 5. 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.

Purpose D0011 standard aims to establish a unified test method in order to evaluate the performance of automotive electronic equipment under various environmental conditions. Therefore, for the each, the general method to be applicable to electronic equipment for automobile has been specified as a representative requirement.
Equipment installed outside the vehicle other than class 4. The test specimen thus moved shall then be tested as it is without any dew being wiped out, in accordance d00 5.
To measure the electric field strength by installing an EM1 meter or spectrum analyzer at the location of the test specimen: 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. 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 to 5.
Results of the study on charged electrostatic voltages of line workers of the automobile manufacturer in winter Fig. This test should be specially applied against the liquid crystal displays, etc. Power supply device of V2 2 5.

Some examples are given below for reference of temperature setting for these equipment. Such devices, therefore, may be excluded d00 this standard, but it is desirable that the test methods specified in this standard are applied to those equipments.
Refer to Attached Fig. Example of material measurement of samples having connecting lead wire Twin cord without shield Ferrite tube: Typical values of the former are as follows, and constants of parts of the test circuit are specified based on them: Equipment to be installed at or near the high temperature portion or other special portion.
JAS0 D 5 Combination of voltage and temperature There was an opinion offered at the committee meeting, under which the conditions for voltage and temperature should be jasp by specifying the normal voltage test to be carried out at high temperature and low temperature, or to make the operational voltage of equipment varied at heat cycle test.
