APPLICATION
Air permeability is an important factor in the performance of such textile materials as gas filters, fabrics for air bags, clothing, mosquito netting, parachutes, sails, tentage, and vacuum cleaners. In filtration, for example, efficiency is directly related to air permeability. Air permeability also can be used to provide an indication of the breathability of weather-resistant and rainproof fabrics, or of coated fabrics in general, and to detect changes during the manufacturing process. In specialty, industrial and military applications, it can play a vital role in protection. In every market, satisfying the demands of consumers and producers requires ways to accurately and repeatably test material air flow.

USAGE
To determine the resistance of fabrics (woven, knitted and nonwoven textile materials) to the passage of air (air flow) under constant pre-set air pressure while firmly clamped in the test rig of selected test head/area.

 

TEST PROCEDURE
1.Test the conditioned specimens in the standard atmospherefor testing textiles, which is 21±1°C (70±2°F) and65±2 % relative humidity, unless otherwise specified in amaterial specification or contract order.
2. Handle the test specimens carefully to avoid alteringthe natural state of the material.
3. Place each test specimen onto the test head of the testinstrument, and perform the test as specified in the manufacturer’soperating instructions.
4. Place coated test specimens with the coated sidedown (towards low pressure side) to minimize edge leakage.
5. Make tests at the water pressure differential specifiedin a material specification or contract order. In the absence ofa material specification or contract order, use a water pressuredifferential of 125 Pa (12.7 mm or 0.5 in. of water).
6.Read and record the individual test results in SI units ascm³/s/cm² and in inch-pound units as ft³/min/ft² rounded tothree significant digits.

 

SALIENT FEATURES
1. Wide measuring range of 0.1-12,000 l/m²/s at 20 cm² test area.
2. Wide test pressure range of 1-4,000 Pa.
3. For filter media: Determination of the pressure drop at a given air velocity.
4. Automatic control of the test pressure.
5. Fast and simple sample clamping(Pneumatic Clamping Assembly).
6. Touch control panel for digital display of the test result.
7. Quiet and mobile instrument, perfectly suitable for use in the laboratory and in the production area.
8. Data ports: RS 232. Ethernet for direct network access.
9.Integrated software for evaluation and storage of the test results in office format.
10. Can be connected to a PC with the Evaluation Program SBT461 Air Permeability Tester lab-cloud.
11. Works in accordance with all major test standards.
