TEMPERATURE & HUMIDITY TESTING, SALT SPRAY TESTING, AND RENTAL SERVICES

What is Temperature & Humidity Testing, Salt Spray Testing, and Equipment Rental?

Temperature & Humidity Testing simulates varying climate conditions to evaluate a product’s resistance to temperature extremes and moisture over time. These tests ensure that components can endure environmental conditions such as thermal cycling, high humidity, or rapid changes in temperature.

Salt Spray Testing (Corrosion Testing) exposes materials to a controlled saline mist to assess corrosion resistance, especially on metal surfaces, coatings, and finishes. It's commonly used in automotive, aerospace, and industrial applications.

Rental Services provide companies access to environmental chambers, salt spray cabinets, and other testing equipment for short-term or project-based use—eliminating the need for upfront capital investment.
 

Why are These Testing Services Important?

These testing services are essential for multiple reasons:
 

• Product Durability: Verifies how long products can perform under harsh environmental conditions.
• Corrosion Resistance: Identifies weaknesses in materials and coatings when exposed to corrosive environments, preventing failures in real-world use.
• Cost Efficiency: Through rental options, businesses can conduct high-quality testing without purchasing expensive equipment.
• Compliance: Helps manufacturers meet standards like ISO 9227 for corrosion and IEC 60068 for environmental testing.
• Market Readiness: Ensures that products are ready for deployment in markets with challenging climates or environments.

Concept of the Testing (Working Principle & Theory Related)

These environmental simulations replicate real-world stressors within a controlled setting:
 

• Temperature & Humidity Chambers: Use precision-controlled systems to simulate hot, cold, and humid conditions, replicating cycles or constant exposure for testing product lifespan or function.
• Salt Spray Chambers: Atomize a saltwater solution into a fog, maintained at consistent temperature and pH, to accelerate corrosion processes.
• Rental Equipment Use: Provides users with full-functioning testing chambers and devices on a temporary basis, allowing independent testing at their facility or lab.

Testing Tools

A variety of tools and chambers are used in temperature, humidity, and corrosion testing:
 

• Environmental Test Chambers: Designed to simulate precise temperature and humidity ranges, including thermal shock, steady-state, or cyclic conditions.
• Salt Spray Cabinets (ASTM B117 compliant): Compact chambers with built-in misting systems to perform continuous or cyclic salt fog exposure.
• Data Loggers & Controllers: Monitor and record environmental conditions throughout the test period for accurate documentation and analysis.
• Rental Units: Include portable or full-sized test chambers, depending on testing requirements and available space.

How to Perform the Testing

Conducting environmental and corrosion testing involves several structured steps:
 

1. Sample Preparation: Clean and prepare samples as per test standard guidelines. Ensure specimens are labeled and documented.
2. Chamber Setup: Configure the chamber to the required temperature, humidity, or salt fog conditions.
3. Test Execution: Run the test over the required duration (e.g., 24h, 96h, 500h), depending on the product standard or durability expectations.
4. Data Collection: Use sensors and loggers to monitor conditions and track results in real time.
5. Post-Test Evaluation: Inspect for physical changes such as rust, corrosion, deformation, or failure in function.
6. Reporting: Document findings with photos, measurements, and pass/fail assessments for quality control or compliance reporting.

Standards for the Testing

Temperature & humidity testing, salt spray testing, and related procedures follow a range of international standards:
 

• ISO 9227: Corrosion Tests in Artificial Atmospheres—Salt Spray Tests
• IEC 60068-2-30: Damp Heat, Cyclic (12h + 12h cycle)
• IEC 60068-2-14: Temperature Change Tests
• ASTM B117: Standard Practice for Operating Salt Spray (Fog) Apparatus
• MIL-STD-810: Environmental Engineering Considerations and Laboratory Tests (Used in military & aerospace industries)
