2Expert Interpretation
This article provides an in-depth analysis of ISO 21927-7:2017, the international standard requirements for flue sections in smoke and heat control systems. It covers the fire integrity of multi-compartment/single-compartment flues, leakage rate test methods, structural support specifications, and maintenance guidelines. It also compares the differences with the EN 1366-8/9 test standards and provides design and implementation recommendations for building fire protection systems.
Analysis of the core requirements of the standard
ISO 21927-7:2017 standard specifies the technical requirements for flue sections in the pressure difference system and the smoke and heat exhaust system, which are mainly divided into two categories: multi-compartment fire-resistant flue section and single-compartment flue section:
| Performance indicators | Multi-compartment flue section | Single-compartment flue section | ||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| Integrity (E) | Need to pass the standard temperature rise curve test | Need to pass the 600℃ limit temperature test | ||||||||
| Leakage rate (S) | According to EN 1366-8/9, the furnace pipe openings must be sealed during the test and the following data must be recorded:
2. Fire resistance test differences Chapter 7 of the standard clearly requires manufacturers to provide: According to the recommendations in Appendix A, the annual inspection should include: Compared with the 2006 edition, the 2017 edition has the following major updates:
