Environmental Testing IS 9000 (Part 8) : 1981

This standard is vital for any equipment exposed to periodic vibration, including:

• Industrial Electronics: Control panels, PLCs, and heavy-duty sensors.
• Consumer Goods: Home appliances and handheld electronic devices.
• Telecommunications: Rack-mounted servers and outdoor transmission hardware.
• Automotive Sub-assemblies: Electronic Control Units (ECUs) and dashboard instrumentation.
• Railway Components: Signaling equipment and on-board electronic modules.

Testing is conducted by subjecting the Equipment Under Test (EUT) to controlled frequency sweeps. The primary parameters include:

• Frequency Range: Typically 10 Hz to 500 Hz (customizable based on application).
• Displacement & Acceleration: Testing at constant amplitude or constant acceleration levels.
• Axis Orientation: Sequential vibration across three mutually perpendicular axes (X, Y, and Z).
• Endurance Testing: Prolonged exposure at resonance or through repeated sweep cycles.

• Standard Testing: 5 to 7 business days depending on the endurance cycle requirements.
• Reporting: Formal test reports are typically issued within 2 to 3 days following the completion of the physical test cycles.

To initiate the vibration assessment, manufacturers must provide:

• Test Samples: 1 to 2 functional units (standard).
• Mounting Fixtures: If the product requires specialized jigs to be secured to the shaker table.
• Technical Specs: Operating manuals and power requirements for functional monitoring during test.

For a seamless certification process, please ensure the following is prepared:

• Product Specification Sheet: Detailing weight, dimensions, and intended environment.
• Circuit Diagrams & BOM: Necessary for internal component identification.
• Previous Test History: Any existing internal R&D data to help optimize sweep parameters.
