Environmental Testing IS/IEC 60068 : Part 2 Sec 38 2009

This test is the ultimate stress check for component integrity. Unlike static testing, IS/IEC 60068: Part 2 Sec 38 utilizes a “breathing” effect—cycling temperature and humidity to force moisture into micro-cracks—followed by a freezing phase to expand that moisture and expose latent defects.

  • Detects Seal Failures: Identifies breaches in hermetic seals and gaskets.
  • Accelerated Aging: Simulates weeks of harsh weather in days.
  • Prevents Field Returns: Catches degradation issues before they reach the market.

Regulatory Benchmark (Applicable Standard)

We strictly adhere to the Indian Standard adoption of the international IEC framework:

  • IS/IEC 60068 : Part 2 Sec 38 (2009)
  • Equivalence: Fully aligned with IEC 60068-2-38 (Test Z/AD: Composite Temperature/Humidity Cyclic Test).

Target Applications (Products Covered)

This standard is critical for equipment designed to survive rigorous outdoor environments or rapid climatic changes.

  • Sealed Electronics: Outdoor sensors, junction boxes, and surveillance cameras.
  • Automotive Components: ECUs and lighting assemblies exposed to weather.
  • Telecommunications: Remote Radio Heads (RRH) and antenna systems.
  • Consumer Goods: Portable devices with IP (Ingress Protection) ratings.

Technical Parameters (Scope of Testing)

Our lab executes the precise "Z/AD" composite cycle to ensure total compliance.

  • Temperature Cycling: Rapid transitions between 25°C and 65°C.
  • Humidity Saturation: Maintained between 80% and 98% RH during high-temperature phases.
  • The "Cold Step": Mandatory excursions to -10°C to freeze trapped moisture and stress mechanical seals.
  • Duration: Customizable cycles (typically 10 cycles) based on product category severity.

Lab Competence (Accreditation)

  • NABL Accredited: Our facility operates under ISO/IEC 17025 quality management systems.
  • ILAC MRA Signatory: Our test reports are recognized globally, facilitating international export without re-testing.

Expected Turnaround (Timeline)

Standard Lead Time: 8 – 12 working days. (Note: This test is time-dependent due to the mandatory duration of the environmental cycles. Expedited slots are available upon request.)

Submission Quantity (Sample Required)

  • Primary: 1 Operational Unit (must be fully assembled with all seals/gaskets in place).
  • Reference: 1 Dummy unit (optional, for thermocouple mounting if internal monitoring is required).

Commercials (Cost)

Pricing is determined by the size of the device (chamber volume occupancy) and the number of cycles required.

  • Please contact our sales team with your product dimensions for a precise quotation.

Submission Protocol (Documentation)

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

  • General Arrangement (GA) Drawing.
  • Product Technical Specification Sheet.
  • User Manual / Operating Instructions.
  • Intended use environment description (for cycle severity selection).

Frequently Asked Questions

This test uniquely simulates a "breathing" effect. By cycling temperature and humidity, it forces moisture into micro-cracks, identifying seal failures that standard static tests often miss.
