First is the inspection of dimensions and appearance. It is necessary to verify whether the length, thickness, and width of the wall panels comply with standard requirements, while also observing the surface to ensure it is flat and free of warping, deformation, blistering, or scratches. For products featuring wood grain or stone textures, particular attention must be paid to the clarity of the pattern, the consistency of color tone, and how naturally and seamlessly the panels align when joined together.
Second is the assessment of physical properties, including impact resistance, flexural strength, and dimensional stability. Through specific mechanical tests, the panels are evaluated to determine whether they are prone to cracking, deformation, or breakage when subjected to mechanical stress or temperature fluctuations. Additionally, their moisture resistance is tested to ensure that they do not swell or suffer structural damage when exposed to high-humidity environments.
Finally, there is the environmental and safety assessment, which focuses on measuring the material's VOC emissions and formaldehyde content to ensure compliance with relevant environmental standards. High-quality PS wall panels should exhibit low odor and low emission characteristics, thereby guaranteeing that their long-term use in indoor settings poses no risk to human health and meets the functional requirements of both residential and commercial spaces.
