3 Terms and Definitions
For the purposes of this Document, the following terms and definitions apply.
3.1 Interior decoration material
Decorative materials that are used for interior decoration of shed panels, wall panels, and floors
in mobile laboratories.
3.2 Wave
The wavy texture or concavity on the decorative surface.
3.3 Spot
Local defects in coating of decorative surface.
3.4 Bubble
The local bulges on the decorative surfaces and floors made of non-metallic materials.
3.5 Scratch
Line-like marks that are caused by scratches on the surface of a material by some sharp object.
3.6 Crease
The material cannot return to its original flat state after excessive bending, leaving color marks.
4 Product Classification
4.1 Classification by type of mobile laboratory
According to different types of mobile laboratories, they are divided into four categories:
decoration materials for physical mobile laboratories, decoration materials for chemical mobile
laboratories, decoration materials for biological mobile laboratories and decoration materials
for comprehensive mobile laboratories.
4.2 Classification by decorative parts
4.2.1 Shed panel
The shed panel refers to the ceiling area inside the laboratory, which provides top protection
space and environmental space for the staff, experimental equipment, and test objects in the
internal working area. Its decoration can be completed at the same time as the top wall of the
mobile laboratory cabin, or it can be decorated separately.
4.2.2 Side wall panel
The side wall panel refers to the wall part inside the laboratory, which provides side protection
space, isolation space, environmental space and equipment fixed support for the staff,
experimental equipment, and test objects in the internal working area. Its decoration can be
completed at the same time as the side wall of the mobile laboratory cabin, or it can be decorated
separately.
4.2.3 Floor
The floor refers to the ground area inside the laboratory, which provides bottom load-bearing
space, equipment fixation space, and personnel activity space for the staff, experimental
equipment, and test objects in the internal working area.
4.3 Classification by material properties
4.3.1 Metal materials
Various types of metal or metal alloy sheets and profiles that meet the performance
requirements of laboratory interior decoration materials.
4.3.2 Non-metallic materials
Various types of polymer sheets, Boeing films, wallpapers, liquid materials and other materials
that meet the performance requirements of laboratory interior decoration materials.
4.3.3 Composite materials
Various metal and non-metal hybrid plates and profiles with laboratory interior decoration
material properties.
5 Technical Requirements
5.1 Specifications
5.1.1 metal composite materials sheets and profiles shall meet the following requirements:
a) Material dimensions comply with technical drawings;
b) Sheet with adhesive layer on the back, the thickness of the adhesive layer is 0.055mm ±
0.01mm;
Material hazardous substance limits:
a) Painted materials: volatile organic compounds (VOCs) content ≤ 200g/L, free
formaldehyde content ≤ 0.1g/kg;
b) Wallpaper, Boeing film materials: free formaldehyde release ≤0.12mg/m3;
c) Floor leather: it shall comply with the provisions of GB 18581-2009.
5.4.9 Acid and alkaline resistance
The material shall be soaked in hydrochloric acid (10%) and sodium hydroxide (10%) solutions
for 24 h. The surface of the material shall not leave permanent traces or discolor.
5.4.10 Water absorption
The material shall have non-absorbent properties, or the overall strength and shape shall not
change after absorbing water.
5.4.11 Anti-static performance
Non-metallic floor materials can quickly discharge electrostatic charges; and the surface
resistivity reaches 105~109Ω. The ground resistance discharge shall comply with the
requirements of SJ/T 11294.
5.4.12 Antibacterial and anti-mildew properties
The material shall have the function of inhibiting the vegetative bodies or propagules of
microorganisms such as bacteria and mold, and the production level of mold shall be level 0~2.
5.4.13 Antibacterial, anti-mildew and durable performance
The material has antibacterial and mildew-proof properties after being washed, and the mold
production level shall be level 0~2.
5.4.14 Salt spray resistance
