It replaces GB/T 24977-2010, which is superseded.

1 Scope

GB/T 24977-2024 is the Chinese general standard for bathroom furniture: vanity units, mirror cabinets, wall and floor cabinets and the tops fitted to them. It is a category with one dominant failure mode, water, and the standard is written around it. It sets the classification and the requirements on the materials and their suitability for a wet environment, the requirements on the surface finish and edge sealing, which is where a panel starts to swell, the appearance and workmanship, the dimensional requirements, the mechanical requirements covering the strength, durability and stability of the cabinet, the doors, the drawers and their runners and the wall fixings, the performance of the top including its resistance to water, heat, staining and chemicals, the moisture resistance and dimensional stability tests that stand in for years of use, the requirements on mirrors and any fitted lighting and electrical parts, and the limits on formaldehyde and other harmful substances, together with the test methods, the inspection rules and the marking, packaging, transport and storage. The 2024 edition replaces GB/T 24977-2010.

This document specifies the product classification, basic requirements, safety requirements, installation requirements, inspection rules, packaging, transportation, storage and use instructions for bathroom furniture, and describes the test methods for the relevant requirements.

This document is applicable to the quality control during the production, installation, inspection and sales of furniture used in toilets and bathrooms; for the furniture used in other similar places, it may serve as a reference.
