T/GDGTA 001-2021 Floor impact sound insulation coating
Basic Information
Scope
Main technical content: This standard specifies the requirements for sound insulation coatings for floorboards. It proposes 16 technical indicators from five aspects: apparent performance, limit of harmful substances, mechanics and durability, combustion performance, and sound insulation performance, to regulate the various performance requirements of sound insulation coatings for floorboards. The apparent performance includes: state in the container, appearance of the coating film, thermal storage stability, and drying time; the limit of harmful substances includes: formaldehyde content, volatile organic compound content, total content of benzene compounds, and radioactivity; mechanics and durability include: bonding strength, wear resistance, water resistance, and alkali resistance; combustion performance includes: combustion performance and smoke emission characteristics; sound insulation performance includes: weighted normalized impact sound pressure level and improvement of weighted impact sound pressure level. At the same time, this standard also provides test methods for detecting various technical indicators. This standard also stipulates the inspection rules for sound insulation coatings for floorboards as a product, and also makes specific requirements for product marking, packaging, transportation, and storage.
