ASHRAE Test Dust

About ASHRAE Test Dust

ASHRAE 52.2 Test Dust is a standardized particle contaminant blend formulated specifically for use in air filter performance testing as per ASHRAE Standard 52.2. This standard defines a method to evaluate air filters based on their efficiency in removing particles sized 0.3 im to 10 im (PM1iPM10 range).

The dust simulates atmospheric particles and is ideal for testing MERV rating, initial resistance, efficiency vs. particle size, and dust holding capacity of HVAC and HEPA filters.

Applications

• HVAC Filter Testing

• HEPA & ULPA Efficiency Evaluation

• MERV Rating Tests (Minimum Efficiency Reporting Value)

• Air Purifier & Air Conditioner Filter R&D

• Environmental Particle Simulation in Labs

• 
  

ASHRAE Test Dust is formulated to specifications shown per ANSI/ASHRAE Standard 52.1 and 52.2. ASHRAE Test Dust is designed for testing filters and components of heating, refrigeration and air conditioning systems. ASHRAE Test Dust #1 has also been used in testing of electronic equipment as well as other industrial and household components. ASHRAE Test Dust is a custom blend of 72% ISO 12103-1, A2 Fine Test Dust, 23% powdered carbon and 5% milled cotton linters.

Precision in Filtration Testing

ASHRAE 52.2 Powder sets the benchmark for laboratory and industrial filtration efficiency tests. Engineered with high purity and stable physical characteristics, it ensures precise and reproducible results. Its particle powder form makes it easy to use with test apparatuses, providing confidence for engineers, quality managers, and researchers alike.


Enduring Quality and Storage

With a stable shelf life under dry, sealed storage conditions, ASHRAE 52.2 Powder remains effective for long-term use. Proper storage guarantees the particle size and purity remain unaltered, contributing to consistent performance during critical testing applications in laboratories and industrial environments.



Purpose of ASHRAE Test Dust

ASHRAE Test Dust is utilized primarily for evaluating the efficiency and performance of air filtration systems in laboratory settings. It simulates real-world particulate contaminants, allowing for consistent and standardized testing procedures as required by ASHRAE 52.2. This makes it indispensable for those seeking reliable, repeatable filtration and HVAC validation results.


Safe Handling and Storage Guidelines

Always handle ASHRAE Test Dust with caution. Avoid inhaling the powder or allowing it to come into contact with your skin. After use, promptly reseal the container and store it in a cool, dry environment to ensure product integrity throughout its 12-month shelf life. Adhering to these instructions maintains both safety and test accuracy.


Versatile Packaging and Application

Packaged in durable plastic bottles or jars, ASHRAE Test Dust is typically available in 1 kg units, although custom sizes can be provided. Its fine particle structure ensures suitability for a range of laboratory and industrial testing, from HVAC systems to clean room validation, meeting the strict criteria outlined by current industry standards.
