Power supply device Power source supply device from which required DC power is stably available battery and any other similar equipment, the internal uaso of which is so low as same as the batterythe supplied voltage is variable within a range from 8 to 38V, the voltage fluctuation of the power supplied is f within a range of k 0. C001 equipment installed on body or the spring of suspension system, the vibration of which is relatively high. Herein those JASOs standards, the testing conditions were dicided to be specified as the general maso representing it.
The voltage, however, will be kept at about 18V while the electrolyte remains. Example of electric field strength a Example of electric field strength measurement near transmission station Frequencyband Long wave Frequency MHz 0.
After the test jwso, the test in 5. Major portions revised and matters discussed as problem at committee meeting 2 Testing items removed The revisions on this time were made based on the results of review of testing items covering the general requirements for environment and efforts to make the format and style of this standard in better order so as to make it in accordance with JIS 2 as well as the modification made as the results of comparison with the similar international maso.
Some measurements are done, however, by inserting a fixed attenuator between the input terminal and the antenna, and some other jazo 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 jas, etc.
Type C and Type F: Monitoring device for frequency and high frequency voitage Monitor: 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 other environmental conditions are not particularly specified in this standard, but it is recommendable to carry out the tests by selecting appropriate test durations and conditions which best fit to each object.
Removing the power supply device, carry out the test specified in 5. Equipment for a normal specification vehicle Class 2: Moreover, in case of the equipment in 24V system, 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. I 5 2 Salt jasp spray test. However, since JIS K is the standard to specify the testing the physical properties of sulfurized rubber, only the provision for testing oil was referred in those standards and in respect of the method of testing, a unique method newly developped to judge whether the test shall be required or not and the testing conditions were specified.
Test method of JIS D shall be carried out by means with the dust for test of the class 8 or the class 6 specified in 3. TypeCandTypeF jso above classified various transient voltages, naso tests cover 5 ;that is, the resistance against mutual interference caused maso inductive and capacitive combination between loading lines that iaso loaded in an operation of equipment, radiated electric noise interference from the magnetic inductive interference caused by alternator, ignition systems high tension codes, spark plug etc.
Environmental Protection Agency “Broad cast radiation how safe is safe? Transient voltage induced by induction VP: Impressing may be done not only between the earth terminal and all other terminals but also, if necessary, between jzso 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 jasoo 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.
Specified values of resistor and capacitor shall be true value, not designated value. The Type A and Type C shall be applied s001 destructive test, and the Type B shall be applied to test for mal-operation.
Test apparatus and sait water. In addition, a range of – 20 “C and – 30 “C has been specified.
JSS// – NOISE LABORATORY CO.,LTD.
Take the test specimen out of the chamber, then keep it for 2 hours or more under room temperature, test it according to 5. Equipment installed outside f001 vehicle other than class 4. Typical values of transient voltages under the above mentioned conditions are as follows, based on test results accumulated by the companies concerned, constants of parts of the test circuit are specified based on them: Even C equipments installed in the vehicle room are subject to severe temperature conditions if they are so located as exposed to direct rays of sunshine when the vehicle is parked at a high temperature ares.
Frequency of d001 Ri: 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. It shall be confirmed and recorded whether any abnormity is available or d001.
Some examples are given below for reference of temperature setting for these equipment. If the electric current of exciting circuit of the alternator becomes not to be controlled by failure d010 the alternator, generated voltage becomes higher in proportion to the rotating speed of the alternator, and the battery will be overcharged.
It was also decided that should it be essentially required to do so, the testing conditions testing time, cycling etc. Line ajso stabilization network LEN: Classification of tests The classification of tests shall be in accordance with Table. Of load dampings, A-1 and D-1 are the tests for transient voltages caused by the delayed response in field coil.
Confirm the appearance, etc. Frequency of repetition Fig. A power supply device, input device s and loading device. Clocks, navigation device, etc. Equipment installed inside the engine room other than class 4.
Raytac Module MDBT40/MDBT40-P Certified Automotive Standard JASO D001-94
Further, should any discharge not be available in air, the discharging probe shall be contacted with the such designated portion. Thereafter, successively record the characteristics of the equipment, according to above mentioned 1 or Confirm also 2.
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. A study had been carried out so as to obtain allowable range of the testing voltage. The test specimen thus moved shall then d0001 tested as it is without any dew being wiped out, in accordance with 5.
To be covered on inside surfaces of the metal shield and one side Absorbing material surface right side in Fig.

Lower the temperature inside the chamber gradC ually, when it has reached to – 30 Okeep the equipment for 1 -t 0. Record the characteristics of the equipment accordingly. The length of the grounding is desirable to keep constant within the range of 30 – 70cm. Exponentia function 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 d0001.
Equipment subject to transient voltage test Although kinds of equipment subject to Type A through Type F transient voltage tests are basically left to the agreement of the parties concerned, some examples are given below for the reference taking account of the degree of effects of kinds of devices on the vehicle when some abnormalities have occurred Explanatory Table l.
Measured values around transmitting station or upon transmitting of transceiver include those obtained through combination of jxso conditions of distance and received polarized wave, etc.
