ASTM F430 - 11 standard specification for paper used for vacuum cleaner filter bags
Air permeability is an important factor in the performance of vacuum cleaner bag filter media, because it is a direct indicator of the resistance to air flow. It may also indicate the size of vacuum cleaner bag needed to achieve the desired air flow volume.
Performance specifications, both industrial and military, have been set up on the basis of air permeability and are used in the purchase of materials where permeability is of interest.
Since air permeability is not a linear function of pressure differential between paper surfaces, all tests should be made at a prescribed pressure differential, 0.5 in. (12.7 mm) of water.
1.1 These test methods cover procedures to be followed for qualifying papers to be used in the manufacture of vacuum cleaner bags and filters. The filtration efficiency of the paper is not evaluated with the use of these test methods.
1.2 The procedures appear in the following sections
Air Permeability (Test Method D 737): 3-5
Basis Weight (Test Method D 646): 6-8
Bursting Strength (Mullen Test) (Test Method D 774): 9-11
Internal Tearing Resistance (Test Method D 689): 12-14
Tensile Breaking Strength (Test Method D 828): 15-17
1.3 The values stated in inch-pound units are to be regarded as the standard.
1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
