Air Permeability Tester of textile fabrics complies with ASTM D737. ISO 9237/7231. BS 5636. etc. It is used to test the resistance of the flow of air through fabrics. There is different air permeability test method to do air permeability testing for textiles, we can offer all the test methods and competitive price.

Testing Standards:

BS 5636:UK standard for fabric air permeability testing.

JIS L1096-A:Japanese method measuring textile air permeability.

DIN 53887:German test for material (textile/paper) air permeability.

ASTM D737:US standard evaluating textile air permeability.

ASTM D3574:Flexible foam material physical property assessment.

EN ISO 9237:European textile air permeability test protocol.

GB/T 5453:Chinese fabric air permeability measurement standard.

EDANA 140.2:Nonwoven air permeability test (EDANA specification).

TAPPI T251:Paper/board air resistance evaluation (US).

EDANA 140.1:Nonwoven material performance testing (EDANA).

AFNOR G07-111:French material air permeability assessment.

ISO 7231:International air permeability standard for materials.

Applications:

The Air Permeability Tester accurately and swiftly determines the resistance of fabrics (woven, knitted and nonwoven textile) 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. The air permeability of the fabric is calculated automatically within a short time.

Basic Configuration：

Sample Holder 5cm2;

Sample Holder 20cm2;

Sample Holder 25cm2;

Sample Holder 38cm2;

Sample Holder 50cm2;

Sample Holder 100cm2;

Calibration plate

Test method：

1.Air permeability definition

What is air permeability? The air permeability is the volume of air passing a fabric under pressure. There are two types of air permeability tester for textiles, Frazier air permeability tester and Shirley air permeability tester. In ASTM D737 test method, we take Frazier air permeability tester as example.

2.Test Objectives:

To determine the air permeability of textile fabrics by calculating the air permeability value.

3.Test Materials:

Woven, knitted and non woven textile materials. eg. cotton.

4.Air Permeability Test Procedure:

4.1 The specimens must be adjusted to the standard atmosphere with 21 +/- 1°C (70 +/- 2°F) and 65 +/- 2 % relative humidity unless there is otherwise specification of contract order.

4.2 Process the specimens carefully and prevent it from changing its’ natural state.

4.3 Place each specimen on the test head of the air permeability tester, and control the test as the operation manual.

4.4 At the conditioned water pressure, making tests accord to the operation manual. In the absence of an operation manual, use a water pressure 125 Pa (12.7mm or 0.5 in. of water).

4.5 Read and record the test results. The air permeability units should be noted. Record the test results respectively in SI units as cm^3/s/cm^2 and in inch-pound units as ft^3/min/ft^2 rounded to three significant digits.

4.6 Take out the tested specimen and continue to test next specimen until the ten specimens have been tested in accordance with the flow of 4.3-4.5.

4.7 In order to make sure a high accuracy, the number of test is at least four.

5.Air Permeability Calculation

5.1 Calculate air permeability of every specimen by reading directly from the tester in SI units as cm^3/s/cm^2 and in inch-pound units as ft^3/min/ft^2. rounded to three significant digits. Please follow the instructions which the manufacturer provides when calculating air permeability.

Note-If air permeability results are 600m (2000 ft) above the sea level, it needs correction factors.

5.2 When data are calculated by computer automatically, the calculation is included in the software. Therefore, it is suggested to verify against the known values and the description of the software which is used in the test.

6.Report

The data which is needed to report is as follows.

6.1 Report whether the air permeability is in accordance with the Test Method D737.

6.2 Report the standard deviation and the variation factor while calculating.

6.3 The difference in pressure of fabric surfaces.

6.4 Report the model and the manufacturer of the air permeability test equipment
