Filtration Efficiency and Air Permeability — Core of Our Dust-Proof Bag Testing Service

Fractional filtration efficiency and particle size removal per ASTM F2100, EN 1822, and ISO 29463 — the dust-proof bag is challenged with a polydisperse aerosol or monodisperse latex spheres, and the upstream and downstream particle counts are measured by optical particle counters to determine the filtration efficiency for particle sizes from 0.3 µm to 10 µm, verifying the bag's dust-proof rating and compliance with the declared performance class.
Air permeability and pressure drop per ISO 5636-3, ASTM D737, and EN ISO 9237 — the volumetric airflow through a defined area of the dust-proof bag material is measured at a controlled differential pressure, providing the permeability value that directly influences the energy consumption of the vacuum motor and the suction power available at the cleaning nozzle.
Initial efficiency and gravimetric arrestance per EN 779 and ASHRAE 52.2 — the weight percentage of a standardized coarse test dust captured by the filter bag is determined together with the pressure drop, providing a comparative baseline for dust-proof bag media selection in industrial dust collection applications.
Most penetrating particle size and minimum efficiency reporting value — the fractional efficiency curve is generated across the full particle size range to identify the particle size at which the dust-proof bag is least efficient, and the MERV or ePM rating is assigned for building services and appliance filter classification.
Pore size distribution and bubble point by capillary flow porometry per ASTM F316 — the pore size distribution of the dust-proof bag material is measured to detect any oversized pores or manufacturing defects that would allow dust bypass and reduce the bag's overall filtration efficiency.

Dust Holding Capacity and Loading Characteristics in Our Dust-Proof Bag Testing Service

Dust holding capacity and terminal pressure drop per ISO 5011 and EN 60312-1 — the dust-proof bag is loaded with standardized test dust at a controlled airflow rate until a defined terminal pressure drop is reached, and the mass of dust retained is measured to determine the bag's service life and the optimal replacement interval.
Dust loading curve and pressure drop evolution per ASTM F1471 and customer protocols — the increasing differential pressure across the dust-proof bag is continuously recorded as dust accumulates, generating the loading curve that predicts the bag's behaviour in real-world usage from clean to fully loaded condition.
Burst and collapse resistance at maximum dust loading per ISO 2941 and ASTM D3786 — the dust-proof bag is tested to the point of structural failure under the maximum pressure differential that could be generated by the vacuum cleaner or dust collector system, ensuring the bag does not rupture when fully loaded.
Dust retention and particle shedding after mechanical shock per customer and internal protocols — the loaded dust-proof bag is subjected to drop and vibration simulations to quantify the amount of dust that escapes from the bag during handling, disposal, and transport, a critical safety parameter for allergen and fine dust exposure.

Physical and Mechanical Durability Testing for Dust-Proof Bags

Tensile strength and elongation at break per ISO 1924-2, TAPPI T494, and ASTM D5034 — the dust-proof bag material is stretched to failure in machine and cross directions to measure the breaking force and stretch, ensuring the bag withstands the mechanical stresses of insertion, removal, and the pressure fluctuations of the vacuum system without tearing.
Tear resistance by Elmendorf and trouser tear methods per ISO 1974 and ASTM D1424 — the force required to propagate a tear from an initial slit is measured to verify the dust-proof bag resists catastrophic failure from sharp debris, zip fasteners, or handling damage during disposal.
Seam strength and burst resistance of the bag assembly per ISO 13935-2 and ASTM D3786 — the welded, stitched, or glued seams of the dust-proof bag are tested to ensure they are at least as strong as the parent material and do not open under the pressure differential generated during vacuum operation.
Flange and collar integrity and pull-off force per customer protocols — the cardboard, plastic, or rubber mounting collar of the dust-proof bag is tested for pull-off resistance and dimensional fit to guarantee a secure, leak-free connection to the vacuum cleaner or dust collector inlet.
Bending stiffness and fold endurance per ISO 2493 and ASTM D2176 — the resistance of the dust-proof bag material to creasing and folding is evaluated to ensure the bag can be pleated, folded, and packaged without loss of filtration integrity.

Chemical Safety and Restricted Substances Compliance for Dust-Proof Bags

RoHS compliance per IEC 62321 and EU Directive 2011/65/EU — quantitative screening for lead, mercury, cadmium, hexavalent chromium, PBBs, and PBDEs in the filter media, adhesives, printing inks, and any plastic components to ensure the dust-proof bag meets substance restrictions for the destination market.
REACH Annex XVII and SVHC screening — targeted analysis of Substances of Very High Concern including phthalate plasticizers, organotin stabilizers, and short-chain chlorinated paraffins that may be present in synthetic filter media and polymeric collars.
Formaldehyde emission from paper and non-woven materials per ISO 14184-1 and EN 717-3 — cold water extraction and spectrophotometric determination of formaldehyde content verify the dust-proof bag does not release harmful levels of formaldehyde into the indoor air during use or disposal.
Heavy metals in packaging per EU Directive 94/62/EC — verification that the sum concentration of lead, cadmium, mercury, and hexavalent chromium in the retail packaging and cardboard collar materials is below the 100 ppm regulatory limit.
Antimicrobial and biocide treatment verification per EU Biocidal Products Regulation — for dust-proof bags treated with antimicrobial agents, the active substance identity and concentration are verified to confirm compliance with the applicable biocidal product authorization.

Environmental and Aging Resistance Testing for Dust-Proof Bags

Resistance to humidity and moisture absorption per ASTM D471 and ISO 5635 — the dust-proof bag is conditioned at elevated humidity and the change in tensile strength, filtration efficiency, and dimensional stability is measured to predict performance in damp environments and during wet vacuuming applications.
Thermal aging and heat resistance per ASTM D573 and ISO 188 — the dust-proof bag material is aged at elevated temperatures to simulate the effect of warm exhaust air from the vacuum cleaner motor, and the retained mechanical and filtration properties are retested to confirm long-term durability.
Resistance to oils, grease, and household chemicals per ASTM D543 and ISO 175 — the filter media is exposed to common household cleaning agents, cooking oils, and automotive fluids to verify no softening, swelling, or loss of filtration efficiency occurs from accidental contact.
Color fastness and staining resistance per ISO 105-B02 and EN 12720 — the dust-proof bag material is tested for dye bleed and resistance to staining from common household substances to ensure the bag maintains an acceptable appearance during use and handling.
