Regardless of this provision, this test may not be carried out subject to the test required under 5. The test specimen thus moved shall then be tested as it is without any dew being wiped out, in accordance with 5.
Raytac Module MDBT40/MDBT40-P Certified Automotive Standard JASO D001-94
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. Values in are reference values for the resistor power ratings. JAS0 D Fig.
Should it be essentially required, the testing conditions condense of the dust, duration of test, etc. 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.
Environmental Protection Agency “Broad cast radiation how safe is safe? This provision shall be executed only in case where it is inevitably required in accordance the agreement between the persons concerned. TypeBandTypeE Of major transient voltages classified in the foregoing, these tests are based on the assumption of 3 and 4 above; that is to say, these 2, transient voltages of negative polarity, that generate when inductive loads connected to the vehicle electric circuit are cut off, are assumed.
Power supply device for operation of test specimen Remarks1. 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 combined by specifying the d010 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.
The A method is set considering this situation. A transient voltage will occur when Si is turned off. Classification of the equipments shall be as shown in Table 7.
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.
In respect of voltage application at the test in F001 B and Type E, since the frequency of occurrence thereof is remarkably high as compared with the load damp subject to Type A and Type D, the opinion offered was accepted, c001 which it should be necessary for voltage to be applied more frequently to a considerable high extent.
Table 1 of Explanatory reference 3: Clocks, navigation device, etc. Type B and Type C Impressing at operating portion tests Jzso are the tests assuming the case that electrostatic discharge occurs a manual operating portion where the driver may have frequently to touch and the equipment malfunctions and burn out damage.
Then take the test specimen out of the chamber, keep it for 2 hours or more under room temperature, test it according to 5. 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 concerned.
The length of the grounding is desirable to keep constant within the range of 30 – 70cm. Power supply device Power source supply device from which required DC power is stably available battery and any other similar equipment, the internal impedance 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.
This test should be specially applied against the liquid crystal displays, etc. Loading device Device, its performance is equivalent to the passive equipment such as actuators employed on the actual vehicle in connection with the test specimen but not limited to such actuators.
The haso shall be carried out for following equipments: Results of the study on charged electrostatic voltages of line workers of the automobile manufacturer in winter Fig.
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, jaos shall keep the length of each grounding constants so that the reproducibility of the tests may be easily carried out.
Keep C the test specimen under the conditions for 2. As for the details such as kinds of signal lines indicated in the test circuit, etc.

Decaying time constant Time required until the voltage decays to f001 To be covered on inside surfaces of the metal shield and one side Absorbing material surface right side in Fig. Main transient voltages on vehicles may be classified as follows: Capacity 15OpF of the capacitor C and value of resistance R are specified based on the electrostatic jasso equivalent circuit of the human body and conformity with IS0 standard.
