Glass Fiber Window Screen Testing Service for Global Fenestration Compliance
As an ISO/IEC 17025 accredited laboratory, we deliver a specialized glass fiber window screen testing service that verifies mesh geometry, mechanical strength, weather resistance, fire performance, and chemical safety of fiberglass insect screening and solar shading fabrics. Our glass fiber window screen testing service supports manufacturers and exporters of PVC-coated fiberglass mesh, vinyl-coated insect screens, and sun control screens who must demonstrate conformity to ASTM D3656, ISO 9044, EN 13561, and regional building and consumer product regulations across the European Union, North America, the Middle East, and Asia. Every test is performed under our CNAS-accredited quality system, producing reports accepted by notified bodies, window OEMs, and procurement teams worldwide.

Mesh Geometry and Dimensional Inspection for Glass Fiber Window Screens
- Mesh count and wire diameter measurement per ASTM D3656 and ISO 9044 — the openings per linear inch and the individual yarn diameters are measured using calibrated optical microscopes and image analysis systems, verifying the screen meets the specified mesh count and yarn size for the intended insect exclusion or solar control function.
- Open area percentage and air permeability calculation per ISO 9044 — the ratio of open aperture area to total screen surface is calculated to confirm the fiberglass window screen provides the specified ventilation, visibility, and solar heat rejection characteristics.
- Roll width, length, and squareness verification per customer specifications — calibrated tapes and laser scanners verify the screen dimensions and edge straightness, ensuring the fabric fits correctly into window frame spline grooves without wrinkling or gapping.
- Weave pattern and visual defect inspection under D65 illumination — systematic examination for broken yarns, double yarns, coating voids, and surface contamination against agreed acceptance criteria and master reference samples.
- Coating thickness and uniformity measurement per ISO 2178 and ASTM B487 — the thickness of the PVC or vinyl coating on the fiberglass yarns is measured to verify the specified weather resistance and color retention of the window screen.
Mechanical and Physical Property Testing for Glass Fiber Window Screens
- Tensile strength and elongation at break per ASTM D5035 and ISO 13934-1 — the fiberglass screen fabric is stretched to failure in warp and weft directions to measure the breaking force and stretch, ensuring the screen withstands installation tension, wind loads, and accidental impacts without tearing.
- Tear resistance by tongue and trapezoid methods per ASTM D5587 and ISO 13937-2 — the force required to propagate a tear from an initial slit is measured, verifying the screen resists damage from sharp objects, pet claws, and rough handling.
- Bursting strength per ASTM D3786 and ISO 13938-2 — the multi-directional resistance to rupture is measured to ensure the fiberglass window screen withstands concentrated pressure from wind, hail, and objects pressed against the screen.
- Puncture resistance per ASTM D2582 — the force required to push a pointed probe through the screen is measured, simulating the impact of branches, tools, and debris against the window screen.
- Abrasion and flex cracking resistance per ASTM D4966 and ISO 7854 — the screen surface is rubbed against a standard abrasive and repeatedly folded to evaluate the resistance to coating wear and yarn breakage during installation and years of window operation.
- Spline retention and pull-out strength per customer and internal protocols — the force required to pull the screen fabric from the window frame spline groove is measured to ensure the screen remains securely attached under wind suction and repeated opening and closing of the window sash.
Weathering and Environmental Durability Testing for Glass Fiber Window Screens
- Accelerated weathering by xenon-arc exposure per ASTM G155 and ISO 4892-2 — the fiberglass window screen is subjected to simulated sunlight, heat, and moisture cycles, and the color change, coating cracking, and retained tensile strength are evaluated to predict the outdoor service life of the screen fabric.
- UV resistance by fluorescent lamp exposure per ASTM G154 — isolating the ultraviolet degradation mechanism to evaluate the screen's resistance to yellowing, embrittlement, and loss of mechanical strength after prolonged sun exposure.
- Damp heat and condensation resistance per IEC 60068-2-78 — the screen is exposed to high temperature and high relative humidity, followed by mechanical and visual retests to confirm no moisture-induced coating delamination or fiber degradation.
- Neutral salt spray and corrosion testing per ISO 9227 — for screens used in coastal and marine environments, the fiberglass and any metal spline or frame components are tested for corrosion resistance and coating degradation.
- Resistance to cleaning agents and household chemicals per ISO 175 and ASTM D543 — the screen surface is exposed to common window cleaners, detergents, and mild solvents to verify no staining, softening, or loss of coating adhesion occurs during routine cleaning.
- Low-temperature flexibility and cold crack resistance per ASTM D2137 — the screen is conditioned at sub-zero temperatures and flexed to verify it remains pliable and does not crack in cold climates and winter installation.
Fire Safety and Restricted Substance Compliance for Glass Fiber Window Screens
- Vertical flame test and limited flame spread per ASTM D6413 and ISO 15025 — the fiberglass window screen is exposed to a defined flame and the afterflame time, afterglow, and char length are measured to classify the flammability for building and consumer product applications.
- Limiting oxygen index per ISO 4589-2 — the minimum oxygen concentration supporting combustion is measured to rank the intrinsic fire resistance of the screen fabric and to verify the effectiveness of flame-retardant treatments.
- RoHS compliance per IEC 62321 and EU Directive 2011/65/EU — quantitative screening for lead, mercury, cadmium, hexavalent chromium, PBBs, and PBDEs in the fiberglass yarns, PVC coating, and any colorants.
- REACH Annex XVII and SVHC screening — targeted analysis of Substances of Very High Concern including phthalate plasticizers, organotin stabilizers, and restricted flame retardants in the plastic coating and any surface treatments.
- Heavy metals and extractable elements per EN 71-3 and ASTM F963 — for screens used in children's rooms and play areas, the migration of antimony, arsenic, barium, cadmium, chromium, lead, mercury, and selenium is tested to verify user safety.
- Formaldehyde and volatile organic compound emission per ISO 16000-3 — chamber testing verifies that the glass fiber window screen does not release harmful VOCs or formaldehyde into the indoor air after installation.
- Heavy metals in packaging per EU Directive 94/62/EC — verification that lead, cadmium, mercury, and hexavalent chromium sum concentration in the packaging is below the 100 ppm regulatory limit.
