GB/T 44749.2-2024 is the second part of the series of standards for testing the delamination resistance of adhesives for indoor wood products. It specifies test methods for delamination resistance under harsh environmental conditions, such as temperatures ranging from -5°C to 60°C, relative humidity between 30% and 95%, and cyclic damp heat. The standard simulates extreme usage scenarios through temperature and humidity cycles, with a focus on measuring key indicators such as peel strength and delamination area ratio. It applies to mainstream adhesives used in indoor wood products like flooring and cabinets, providing a basis for selecting high-durability products. The tests require the use of a dual-controlled environmental test chamber for temperature and humidity, a peel testing machine with a force accuracy of ±1%, and instruments such as a vernier caliper with an accuracy of 0.01 mm and a moisture content meter to ensure reliable results.
