JASO D001-94

However, voltages that are jas and impressed by transient voltages and electro-magnetic disturbances are not included. Classification of tests The classification of tests shall be in accordance with Table. Definitions Definitions of major terms used in this standard are as follows: Ammeter The accuracy shall be in class equal to or higher than 0. Voltmeter The accuracy shall be in class equal to or higher than 0.

Power supply device Power source v001 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. 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 specimen, but not limited to such sensors.

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 naso not limited to such actuators. Where any imitated load may be employed over such specimen, should any effect be directly given to the result of testing. Equipment for a normal specification vehicle Class 2: Limited naso equipments of special ajso vehicles under the agreement between the persons concerned where, Vi: Frequency of repetition Fig.

Power supply device of V i E: Power supply device of V2 2 5. Input device s and loading device s. The test specimen shall be operated under the test voltage having been applied thereto, after the operation of ajso specimen is stabilized, output of power source micro interruption equipment shall be micro interrupted and whether any abnormity maso or not of specimen shall be confirmed and recorded.

Should any abnormality be detected, the duration of time when jaaso voltage has been kept applied and the conditions thereat shall be recorded. In case where no abnormality is found after applying the test voltage for 60 minutes, record it and the test may be stopped. Removing the power supply device, carry out the test specified in 5. Connect the input and loading device to the test speciment so that the equipment may operate during the test; connect the assembly to the test apparatus specified in 5.

As agreed between the persons concerned. Exponential function type decaying jasoo polarity transient voltage Type B and Type E: 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.

Type C and Type F: Transient voltage induced by induction VP: Maximum value of transient voltage T: Decaying time constant Time required until the voltage decays to Frequency of repetition Ri: Output impedance of the test voltage generating circuit Fig. Care must be taken because batteries may explode if sparks are generated near them. Jask transient voltage will occur when Si is turned off.

Power source of charge on capacitor C Ei: Power supply device for operation of test specimen Remark The constant of each circuit element shall be as listed Table 4. Values in are reference values for the resistor power ratings. Specified values of resistor and capacitor shall be true value, not designated value.

Power supply device for operation of test specimen Remarks1. Constants of circuit are as listed in Table 5. I Type B 1 sec or more I. The Type A and Type C shall be applied to destructive test, and the Type B shall be applied to test for mal-operation. 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. It shall be confirmed and recorded whether any abnormity is available or not.

Further, should any discharge not be available in air, the discharging probe shall be contacted with the such designated portion.

I btl Measureing instrument Loading Input device where, Low frequency oscillar: Core shall not be saturated. The same as shown in Fig. Line impedance stabilization network LEN: Refer to Attached Fig. A power supply device, input device s and loading device. Output impedance 2 R or less, output 50W or grater Ammeter: O to 30A, 30Hz to 15kHz Fig.

Monitoring device for frequency and high frequency voitage Monitor: To measure the electric field strength by installing an EM1 meter or spectrum analyzer at the location of the test specimen: Logarithmic conical spiral Transmitting antenna: Transmitting antenna hood with absorption material An aluminum, Metal shield cylinder and end plate with 3. To be covered on inside surfaces of the metal shield and one side Absorbing material surface right side in Fig. Any test specimen shall be operated after the power supply device, input device and loading devices have been connected therewith, the operation of which shall be monitored by means with a proper monitoring equipment.

This test, however, shall not be applied to the case of a chamber of O or C more. The classifications of the equipments shall be as follows: Equipment installed in the vehicle compartment and the trunk room, other than class 4. Equipment installed outside the vehicle other than class 4.

Equipment installed inside the engine room other than class 4. Equipment to be installed at or near the high temperature portion or other special portion. The class 3 carry out according to necessary condition.

Make the temperature in the chamber gradually approached to a setting temperature specified in Table 7; and when the temperature has reached to the setting temperature, keep the naso under the temperature during 1 I0.

Then, make the temperature gradually approached to other temperature and record in like manner. The test order of setting temperature is not particularly specified. Lower the temperature gradually, jqso the temperature has reached to – 30 O Ckeep the equipment for 1 f 0. Further, operate the test specimen for 70 f 2 hours under the temperature. Take the specimen out of d001 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.

Further, jasl 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, shall not be applied to the case of a chamber of O or C more. Then take the test specimen out of the chamber, keep it for 2 hours or jaxo under room temperature, test it according to 5.

Classification of the equipments shall be as shown in Table 7. The of class 3 carry out according to necessary conditions. 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.

Further, operate the test specimen v001 k 2 hours under the specified temperature. Take the test specimen out of the chamber, then keep it for 2 hours or more under room temperature, test it according to 5.

Lower the temperature inside the chamber gradC ually, when it has reached to – 30 Okeep the equipment for 1 -t 0. Further, carry out the test pattern specified in Fig. Take the test specimen out of the chamber and keep it for 2 hours or more under room temperature, test it according to 5. Regarding above operations as one cycle refer to Fig.

Then carry out the test according to 5. JASO D possible. A power supply device, input device s and loading devices s. Keep Jsso the test specimen under the conditions for 2. Carry out the test pattern shown in Fig.

Subsequent operations shall be as f001 I After keeping the test specimen for 1. Appearance and other conditions of the test equipment at that time shall also be confirmed.

Record the characteristics of the equipment accordingly. Confirm the appearance, etc. Thereafter, successively record the characteristics of the equipment, according to above mentioned 1 or 2. Confirm also the appearance, etc. Setting temperature shall be as shown in Table Place the test specimen in the constant temperature and humidity chamber, raise gradually the temperature and humidity in the chamber.

Then operate the test specimen under the same condition for 94 -t 2 hours. Appearance and other jaos o the f equipment at that time shall also be confirmed. The test specimen thus jaeo shall then be tested as it is without any dew being wiped out, in accordance with 5.

In addition, any conditions including but not limited to the visual appearance shall also be verified. Appearance and other conditions of the equipment at that time shall also be confirmed.
