Antifungal and mold resistance per ASTM G21 and ISO 846 — the board is inoculated with Aspergillus niger, Penicillium funiculosum, and other fungal spores, and the visible growth is assessed after 28 days under high humidity to confirm the board resists mold colonization in damp environments.
Antiviral activity testing per ISO 21702 — for boards used in healthcare and public spaces, the reduction in infectious virus particles on the surface is measured to verify the antimicrobial treatment provides antiviral protection.
Durability of antibacterial treatment after cleaning and abrasion per internal protocols and ASTM D4060 — the board is subjected to repeated wiping, cleaning, and mechanical abrasion cycles, and the antibacterial efficacy is remeasured to confirm the antimicrobial function is retained over the service life.
Resistance to bacterial biofilm formation per ASTM E2871 — the composite board is tested in a flow cell or static culture to evaluate its ability to inhibit biofilm development, which is critical for surfaces in food processing and medical facilities.
Leaching and migration of biocidal substances per ISO 10993-5 and EU Biocidal Products Regulation — the board is extracted with water and food simulants to verify that antimicrobial additives do not leach into the environment or contact fluids at unsafe levels.

Fire-Resistant and Reaction-to-Fire Testing for Composite Boards

Euroclass reaction-to-fire classification per EN 13501-1 — the composite board is tested for ignitability, flame spread, and heat release using the single burning item test and the small flame test, generating the classification required for CE marking in European construction markets.
Surface flame spread and smoke developed index per ASTM E84 — the Steiner tunnel test measures the flame spread and smoke generation of the composite board, verifying Class A or Class B performance for North American building code compliance and insurance requirements.
Non-combustibility and limited combustibility per ISO 1182 and EN ISO 1716 — for mineral-core composite boards, the furnace test and calorific potential measurement confirm the core material does not contribute fuel to a fire, supporting use in fire-rated assemblies.
Fire resistance integrity and insulation of the complete panel assembly per EN 1364-1 and ASTM E119 — a full-scale wall or ceiling specimen incorporating the composite board is exposed to the standard fire curve to establish the fire resistance rating for compartmentation and structural protection.
Smoke density and toxic gas emission per ISO 5659-2 — for boards used in enclosed public spaces and transport, the specific optical density of smoke and the concentration of toxic combustion gases are measured to meet life safety evacuation requirements.
Glow-wire ignitability and hot-wire resistance per IEC 60695-2-11 — the board is subjected to a glow-wire at defined temperatures to simulate contact with an overheated electrical component, verifying the material does not ignite or self-sustain combustion.
Cone calorimetry for heat release rate per ISO 5660-1 and ASTM E1354 — the board is irradiated with a defined heat flux, and the heat release rate, total heat released, and effective heat of combustion are measured to provide the fundamental fire properties for performance-based fire engineering design.

Mechanical and Structural Performance Testing of Composite Boards

Flexural strength and modulus per ISO 178, ASTM D790, and EN 310 — three-point bending tests determine the board's resistance to bending and its stiffness, ensuring the composite panel can support loads, span supports, and resist wind pressure without excessive deflection or failure.
