3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Fire-resistant expansion seals are materials that expand when
exposed to fire or high temperature and are used to assist building components in providing fire-resistant sealing properties such as fire isolation, smoke isolation and heat insulation.
3.2
Intumescent components are materials in fire-resistant
intumescent seals that expand when exposed to fire or high temperatures.
4. Grade code and model compilation
4.1 Grade code
The smoke density and smoke toxicity grade codes of fire-resistant expansion seals are shown in Table 1, and the fire-resistant sealing grade codes are shown in Table 2.
Table 1 Codes for smoke density and smoke toxicity levels of fire-resistant expansion seals
Table 2 Fireproofing and Sealing Grade Code
Fire sealing requirements
Overall fire resistance integrity of building components ÿ180min
Overall fire resistance integrity of building components ÿ120min
Overall fire resistance integrity of building components ÿ90min
Overall fire resistance integrity of building components ÿ60min
Overall fire resistance integrity of building components ÿ30min
4.2 Model compilation
The method for compiling the model of fire-resistant expansion seals is shown in Figure 1.
Figure 1: Model compilation of fire-resistant expansion seals
Example 1: FPJ-Y1D3F1.0-10-15×2-A, indicating smoke density level 1, smoke toxicity level 3, and overall fire resistance integrity of the building components used ÿ60min, nominal expansion ratio 10 times, rectangular cross-section width 15mm, thickness 2mm, enterprise-defined fire-resistant expansion seal A.
Example 2: FPJ-Y2D2F1.5-8- ÿ 6-B, indicating smoke density level 2, smoke toxicity level 2, and overall fire resistance integrity of the building components usedÿ90min, nominal expansion ratio 8 times, circular cross-section outer diameter 6mm, enterprise-defined fire-resistant expansion seal B.
Example 3: FPJ-Y3D1F0.5-6-13×3, indictating smoke density level 3, smoke toxicity level 1, and overall fire resistance integrity of the building components used ÿ30min, nominal expansion ratio 6 times, fire-resistant expansion seal with special-shaped cross-section characteristic dimensions of 13mm×3mm.
