(1) The vibration conditions of the components are classified according to the types of vehicles to which they are to be mounted, as follows.
\u3000\u3000\u3000Type 1: Mainly passenger vehicles
\u3000\u3000\u3000Type 2: Mainly buses
\u3000\u3000\u3000Type 3: Mainly trucks<\/span>
\u3000\u3000\u3000Type 4: Mainly motorcycles<\/p>\n\n\n\n

(2) The vibration conditions of the components are classified according to their installed condition, as follows.
\u3000\u3000\u3000Class A: When mounted on the vehicle body or on the suspension system above the spring, and subject to relatively low vibration
\u3000\u3000\u3000Class B: When mounted on the vehicle body or on the suspension system above the spring, and subject to relatively high vibration
\u3000\u3000\u3000Class C: When mounted on the engine and subject to relatively low vibration
\u3000\u3000\u3000Class D: When mounted below the suspension spring or on the engine, and subject to relatively high vibration<\/span><\/p>\n\n\n\n

Details above are excerpted from JIS D 1601-1995 \u201cAutomotive Parts Vibration Test Method\u201d<\/p>\n\n\n\n

(4) The test was conducted under the following conditions: (1) Type 3, (2) Class D, (3) Frequency of 67 Hz (equivalent to vibrations at approximately 2,000 rpm in a 4-cylinder engine). In addition, a 60 sq wire was connected to the test sample, and the test was performed under high-load conditions.<\/p>\n\n\n\n

Test Method Details<\/div>\n\n\n\n

The focus of the test was to verify the vibration resistance of the bent section extending from the terminal body to the vertical M8 bolt.<\/p>\n\n\n\n

A 60 sq wire was attached to the M8 vertical bolt. To increase the load on the bent section and assess its vibration reliability, external vibrations were intentionally applied\u2014not only to evaluate the terminal itself but also to simulate high-load conditions.<\/p>\n\n\n\n

The following video shows the test in progress based on the conditions described on the previous page (4). The vertical amplitude is approximately 1 mm, and the corresponding acceleration reaches 90 m\/s\u00b2 (approximately 9.2 G).<\/p>\n\n\n\n
