JASO D General Rules of Environmental Testing Methods for Automotive Revision: Edition, ; Published Date: January ; Status: Not Active, . simulate this condition include the U.S.’s ISO pulse 1 and 3a, and Japan’s JASO D, standard type B and E. Each peak voltage for these tests is. The MPG S21 has a built-in battery switch to interrupt the DC supply voltage and is specifically designed for JASO. D, test pulses E1 and E2.

Appearance and other conditions jzso the f equipment at that time shall also be confirmed. Further, measuring accuracy and reproducibility of TEM cell test method using the reference sample, that careful consideration is necessary on the following points: Removing the power supply device, carry out the test specified in 5. This test, therefore, aims to evaluate the electromagnetic environmental resistance by way of the design standard to protect equipment and to ensure functions of equipment from such troubles.
Three points test voltages including both extreme values shall at least be performed, and more points are left to the agreement between the persons concerned. Appearance and other conditions of the test equipment at that time shall also be confirmed. Power source of charge on capacitor C Ei: When establishing the provision for the standard, only open circuit was assumed, because the duration of transient voltage tends to prolong significantly when the ignition circuit is opened as compared with the case where the circuit is closed.
As for the intensity of d01-94 electromagnetic field to be impressed in the test, the numerical values of 0. To be covered on inside surfaces of the metal shield and one side Absorbing material surface right side in Fig. Some examples are given below for reference of temperature setting for these equipment. It is also expected that the voltage may rise near to the primary inductive voltage at the time when d001-49 breaker is connected, according to the condition of arc discharge suppression.
Then operate the test specimen under the same condition for 94 -t 2 hours.
Any test specimen shall be operated after the power jsao device, input device and loading devices have been connected therewith, the operation of which shall be monitored by means with a proper monitoring equipment. 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.
It would be difficult to get test gear.

Capacity 15OpF of the capacitor C and value of resistance R are specified based on the electrostatic discharge equivalent circuit of the human body and conformity with IS0 standard. Appearance and other conditions of the equipment at that time shall also be confirmed. 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 specimen under the temperature during 1 I0.
A power supply device, input device s and loading device.

JASO D possible. Of load dampings, A-2 and D-2 are the tests for transient voltages caused by the inverse electromotive force of the stator coil. Ammeter The accuracy shall be in class equal to or higher than 0. Foregoing results are, however, obtained on bench assembled tests, and it was confirmed that only jasoo lower transient voltage would occur on vehicle tests as compared with bench tests.
Further, the car radio, audio players and N s may be automotive electric equipments, but they have few necessary to meet severe environmental immunity as in jasl case of control electronic equipments. Should there any resonance be available, the test shall be carried out in accordance with ” 2 In case of occur in pesonance vibration” of 5.
Although it is desirable that the test apparatus shown in Fig. 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 normal voltage test to be carried out at high temperature and low temperature, or to make the operational jaeo of equipment varied at heat cycle test.
In addition, those values are the examples of readings. In case of the equipment, the heat mass of which are utmost high, the duration of time for holding at low temperature and the time required of release in constant temperature and humidity chamber may be optionally fixed jso accordance with the agreement made between the persons concerned.
Keep C the test specimen under the conditions for 2. For 12V system, two kinds of voltages, 6V class 1 and 5V class 2are selected as the mini- the Text A test jjaso evaluate the characteristics of the equipment against the power supply voltage excluding the case jasso engine starting, when the power supply system is normal, and is desirable to jxso carried out for every kind of equipments.
Number of impressions is specified as 3 times or more, but about 10 times are desirable. The class 3 carry out according to necessary condition. Equipment to be installed at or near the high temperature portion or other special portion.
Classification of tests The classification of tests shall be in accordance with Table. As was the case of A-1 and D-1, the test conditions the test circuit and the constants of its parts are specified based on the test results under the same operating conditions for alternator with A-1 and D-l. The of class 3 carry out according to necessary conditions. I After keeping the test specimen for 1.
