[JASO/JIS/IEC] Standards and Inspection Settings for Momentary Disconnection Testing

Concept of Testing & Inspection

【JASO/JIS/IEC】瞬間断線の規格と検査設定値について

Momentary disconnection testing is in increasing demand these days. In order to conduct strict testing in accordance with each standard, it is necessary to match the specifications of the Momentary disconnection tester. NMS10 Momentary disconnection tester is designed for JASO. Testing according to JIS/IEC standards can be achieved by customization.

Momentary disconnection testing in automotive standard JASO D616 5.13

In many cases, the JASO standard for momentary disconnection testing in the automotive industry defines a resistance fluctuation of 7 Ω as a momentary disconnection.
Example of test settings
In the NMS10 momentary disconnection tester, set the judgment resistance value to 7 Ω.
The NM11B momentary disconnection tester can be customized for testing with the momentary disconnection resistance value set to 7 Ω.

Momentary disconnection testing according to JIS C 5402-2-5:2005 (IEC 60512-2-5:2003)

JIS/IEC standard states that when voltage exceeds 50 % of the supply voltage.
(Or when the voltage at both ends of an open contact falls below 50% of the supply voltage).
Example of test settings
NMS10 is equivalent to JIS/IEC standards according to any of the following settings.。
・Testing current 1000mA, momentary disconnection threshold 12Ω
・Testing current 100mA, momentary disconnection judgment value 120Ω
・Testing current 10mA, momentary disconnection judgment value 1.2KΩ
*The standard testing voltage of NMS10 is 12VDC. 10VDC or lower can be customized.。
