Scope: This document specifies the terms and definitions, requirements, testing methods, inspection rules, and marking, packaging, storage, and transportation for antibacterial and antiviral decorated wood-based panels. This document applies to the production, trade, inspection, and quality assessment of decorated wood-based panels with antibacterial and antiviral properties, such as impregnated film paper, polyolefin films, paints, etc. The aforementioned decorated wood-based panels can be referenced for use. This document does not apply to photocatalytic antibacterial and antiviral decorated wood-based panels that require light exposure to achieve antibacterial and antiviral effects. Main technical content: Terms and definitions: - The terms and definitions defined in GB/T 18259–2018 and the following terms and definitions apply to this document. - Decorated wood-based panels: Wood-based panels with a substrate, which are coated or decorated with various materials. [Source: GB/T 18259–2018, Section 2.13] - Antibacterial: The state of a product's surface inhibiting bacterial growth, or the effect of an agent inhibiting bacterial growth on the product's surface. [Source: GB/T 31402–2015, Section 3.1] - Antiviral: The state of a product's surface reducing the number of infectious virus particles. [Source: ISO 21702:2019, Section 3.1] - Antibacterial and antiviral decorated wood-based panels: Decorated wood-based panels with antibacterial and antiviral properties. - Antibacterial rate: The percentage difference between the average number of recovered bacteria on the test sample and the control sample after inoculating the test bacteria for a certain period of time, compared to the average number of recovered bacteria on the control sample. [Source: LY/T 1926–2020, Section 3.2, with modifications] - Antiviral activity rate: The percentage difference between the average number of recovered virus infections on the test sample and the control sample af
