Environmental Testing JIS D 1601 : 1995 for Automobile Parts

• Primary Standard: JIS D 1601:1995 (Vibration Testing Methods for Automobile Parts).
• Harmonization: Testing protocols are often cross-referenced with manufacturer-specific (OEM) standards (e.g., Toyota, Honda, Nissan specifications) and can be mapped against ISO 16750-3 requirements where applicable.

This standard is broadly applicable to varying classes of vehicle parts based on their mounting location and vibration severity.

• Electrical & Electronics: ECUs, sensors, relays, wiring harnesses, and infotainment systems.
• Lighting Systems: Headlamps, tail lamps, and indicators (filament and LED).
• Mechanical Assemblies: Mirrors, wiper motors, pumps, and brackets.
• Engine & Powertrain: Parts mounted directly to the engine block requiring high-G resistance.

We conduct the full suite of vibration modalities specified under the standard, ensuring a "pass" verdict implies genuine durability.

• Resonant Frequency Detection: Identifying critical frequencies where the part amplifies vibration.
• Vibration Function Test: Verifying the part operates correctly during active vibration.
• Vibration Endurance Test: Subjecting the part to sustained vibration at fixed resonant frequencies.
• Sweep Vibration Endurance: Cycling through frequency ranges to test broad-spectrum durability.
• Axes Tested: Orthogonal testing in Vertical (Z), Transverse (Y), and Longitudinal (X) directions.

All testing is conducted in partner laboratories that hold the highest levels of technical competence.

• ISO/IEC 17025 Accredited: Labs are NABL accredited (or equivalent ILAC signatory).
• Calibrated Instrumentation: Utilizing advanced electrodynamic shakers and accelerometers traceable to national standards.

• Standard Lead Time: 5 to 8 Working Days (depending on the duration of the endurance cycles required).
• Expedited Services: Priority slots available for urgent production deadlines.

• Quantity: Typically 2 Units (1 Main Sample + 1 Control/Backup).
• Condition: Samples must be fully functional and production-ready.
• Fixtures: If the part requires a specialized mounting jig to attach to the vibration shaker, this must be provided or fabricated (can be arranged upon request).

• Pricing Structure: Costs are calculated based on the weight of the sample, the number of axes to be tested, and the total duration (hours) of the vibration cycle.
• Action: Please submit your product technical sheet for a custom quotation.

To initiate the testing process, the following documents are required:

• Technical Datasheet (TDS): Detailing product specifications and weight.
• General Arrangement (GA) Drawing: To determine mounting points for the shaker table.
• Circuit Diagram: (For active electronic components only).
• OEM Specification Sheet: If specific G-levels or frequency ranges beyond the standard JIS D 1601 tables are required.
