- 3.1 Definitions
- 3.2 Acronyms and Abbreviations
- 4. Test Methodology [Go to Page]
- 4.1 Sequence of Test Events. The objective of Standard 199 is to quantify the performance of a dust collection system as defined Section 2. To achieve this, the black box concept has been employed. The test consists of six distinct stages run continu...
- 5. Test Apparatus [Go to Page]
- 5.1 Dust Feeder/Dispersion System. The dust feeder shall be capable of continuously feeding the test dust at 1 gr/ft3 (2.28 g/m3) at the specified airflow. The dust feeder shall incorporate a scale with active feedback control, such that the dust fee...
- 5.2 Test Duct. The test duct shall consist of round duct sections sufficient to maintain an inlet carrying velocity between 3500 to 5000 ft/min (17.78 to 25.4 m/s). The upstream and downstream duct diameters shall be the same from the inlet to 1 duct...
- 5.3 Pulse Cleaned Dust Collector. The requestor shall supply all items, including pulse cleaning system with control, filter housing, filters, and continuous dust removal system. The system shall be set up to clean a maximum of 25% of the filter medi...
- 5.4 Blower and Associated Control System. The blower and associated control system shall have sufficient capacity to consistently maintain specified airflow throughout the test.
- 5.5 Instrumentation
- 5.6 Lab Conditions. Temperature shall be kept between 60°F and 100°F (16°C and 38°C). Relative humidity shall be kept between 45% ±10% rh. These conditions apply to the lab and the inlet airstream.
- 6. Test Materials [Go to Page]
- 6.1 Test Dust. Test dust shall be fine ground calcium carbonate (wet ground marble) with the following typical properties:
- 6.2 Membrane. The gravimetric sampling shall be conducted on a commercially available ePTFE membrane with maximum 0.45 μm pore size.
- 6.3 Compressed Air. Compressed air shall be provided by an oil-free compressor with clean plumbing that meets ISO 8573-1 3 for particulate, humidity, and oil. The air supply to the pulse cleaning system should have sufficient capacity to maintain the...

- 8. Qualification/Maintenance of Test Setup [Go to Page]
- 8.1 Airflow Rate. Airflow rate shall be measured in accordance with ASHRAE Standard 41.2 1.
- 8.2 Airflow Rate Stability. Measure the airflow according to 8.1 at the minimum and maximum airflow rate. Calculate a coefficient of variation (CV) based on 30 samples collected uniformly over 30 min.
- 8.3 Upstream Airflow Uniformity. The uniformity of the air velocity across the duct cross section shall be determined by a multipoint velocity traverse per ASHRAE Standard 41.2 1.
- 8.4 Duct Leakage. The leak rate of the downstream test duct shall be evaluated in the following manner.
- 8.5 System Cleanliness. The pulse cleaned dust collector downstream of the filters and downstream test duct shall be vacuumed, wiped down with wet wipes, and towel dried between tests to eliminate potential dust shedding from the system itself.
- 8.6 Ambient Air Temperature. Measure the air temperature to within ±1°F (0.56°C) of the actual value using a NIST traceable sensor.
- 8.7 Ambient Air Relative Humidity. Measure the relative humidity to within ±2% rh of the actual value using a NIST traceable sensor.
- 8.8 Compressed Air Particulate Purity. Compressed air particulate purity shall be measured in accordance with ISO 8573-4.
- 8.9 Compressed Air Humidity. Compressed air humidity shall be measured in accordance with ISO 8573-3.
- 8.10 Compressed Air Oil Purity. Compressed air oil purity shall be measured in accordance with ISO 8573-2.
- 8.11 Pulse Cleaning System Pressure. Pressure sensor calibration shall be NIST traceable per the manufacturer’s recommendations.
- 8.12 Pressure Transducers. Pressure sensor calibration shall be NIST traceable per the manufacturer’s recommendations.
- 8.13 Dust Feed Rate. The dust feed system shall be validated as follows.
- 8.14 Dust Dispersion System. Pressure sensor calibration shall be NIST traceable per the manufacturer’s recommendations. Visually inspect the nozzle and replace if worn.
- 8.15 Aerosol Photometer. Photometer shall be calibrated to the test dust per the manufacturer’s instructions and set to a time constant of 60 s.
- 8.16 Background Check. Operate the system for 15 min at specified flow. Then with no filters installed and the system operating at specified flow, take readings from the photometer once per minute for 5 min. Calculate the average PM10 readings. Insta...
