Environmental Testing IS 9000 Part 11 : 1983 Part XI Salt Mist Test

While the standard is broad, it is mandatory for equipment exposed to the elements, including:

• Outdoor Infrastructure: Street lighting, solar inverters, and EV charging stations.
• Telecommunications: Outdoor routers, antennas, and base station components.
• Automotive Electronics: Sensors and control units located in exposed vehicle areas.
• Consumer Goods: Air conditioning outdoor units and marine-grade appliances.

The testing scope encompasses a controlled simulation within a pressurized chamber. Key parameters include:

• Atomization: Exposure to a 5% NaCl solution mist.
• Thermal Control: Constant chamber temperature of $35^\circ\text{C} \pm 2^\circ\text{C}$.
• Duration Cycles: Ranging from 16 hours to 96 hours (or more), depending on the specific product category.
• Post-Test Analysis: Rigorous visual inspection for base-metal oxidation and functional electrical verification.

To ensure the reports are legally valid for BIS or export purposes, testing must be performed in labs accredited by:

• NABL (National Accreditation Board for Testing and Calibration Laboratories).
• BIS Recognized Labs (Specifically for products under Compulsory Registration).

• Sample Logistics: 1–2 working days.
• Chamber Exposure: Subject to the duration specified in the product standard (e.g., 48h, 72h, or 96h).
• Reporting & Review: 3–5 working days post-test completion.
• Total Turnaround: Approximately 7 to 12 working days.

• Quantity: Typically 2 to 3 units are required (one for active testing and one for reference).
• Condition: Samples must be in their final production finish (including all coatings and enclosures).
• Operation: For active testing, any necessary power cables or controllers must be provided.

The cost varies based on two primary factors:

1. Chamber Duration: Longer exposure cycles (e.g., 168 hours) incur higher utility and monitoring fees.
2. Product Complexity: Large or heavy equipment requiring specialized mounting or active functional monitoring during the test. Contact our technical team for a precise, per-sample quotation.

To initiate the testing process, the following are required:

• Technical Data Sheet (TDS): Detailing material composition and coating types.
• Product Manual: Instructions for operational checks.
• Application Form: Duly filled with manufacturer details and model numbers.
• Circuit Diagrams: For electrical items requiring functionality checks post-exposure.
