Fluid handling capacity for wound exudate per EN 13726-1 — the hydrogel film is tested with simulated wound fluid to measure the total fluid handling capacity, verifying the dressing can absorb and retain exudate while maintaining its structural integrity.
Moisture vapor transmission rate per ASTM E96 and ISO 15106-2 — the water vapor permeability of the hydrogel film is measured to ensure the dressing provides an optimal moisture balance at the wound site, promoting healing while preventing maceration.
Swelling reversibility and cycling stability per internal protocols — the hydrogel film is subjected to repeated swelling and drying cycles, and the change in mechanical properties and dimensions is recorded to predict long-term performance under fluctuating humidity conditions.

Biocompatibility and Safety Testing for Hydrogel Films

Cytotoxicity evaluation per ISO 10993-5 — extracts of the hydrogel film are applied to cultured cells to verify the material does not exhibit toxic effects, a fundamental safety requirement for medical devices in contact with skin and tissue.
Skin irritation and sensitization testing per ISO 10993-10 — the hydrogel film is tested on reconstructed human epidermis or under clinical conditions to confirm it does not cause erythema, edema, or allergic skin reactions during prolonged contact.
Systemic toxicity and genotoxicity per ISO 10993-11 and ISO 10993-3 — the biological response to leachable substances from the hydrogel is evaluated to detect any systemic or genetic toxic effects.
