IAS-Certified Firestop Inspection Added to CNS Standards
In modern building safety management, firestop systems are critical to overall fire performance and regulatory compliance. Liansuo Construction Technology Co., Ltd., operating as an IAS Type A Inspection Body (AA-864) under ISO/IEC 17020:2012 standards, is proud to announce that its firestop inspection services have been officially incorporated into Taiwan’s CNS 15814 series of national standards, effective from April 15, 2025. With increasingly stringent fire regulations, this expanded qualification will further enhance building protection capabilities and meet compliance needs across diverse environments.
Service Scope Expansion
In addition to its existing inspection capabilities based on UL/FM methodologies and compliant with ASTM E2174 (for penetration firestops) and ASTM E2393 (for joint systems), Liansuo Construction Technology can now address:
-
CNS 15814-1: Penetration Sealing Materials
Evaluating the “fire resistance,” “flame shielding,” and “thermal insulation” properties of various pipelines and cables passing through firewall or floor openings, ensuring they do not become pathways for fire spread. -
CNS 15814-2: Linear Joint Sealing Components
Assessing the “fire resistance,” “thermal insulation,” and “movement capability under structural displacement” of joints between walls, or between walls and floors, ensuring firestop performance is maintained during vibration or thermal expansion and contraction.
Typical Application Scenarios
Our firestop inspection services are widely applied in high-rise buildings, commercial office towers, medical facilities, semiconductor cleanrooms, and energy storage facilities, meeting fire compliance requirements across various settings.
Rigorous Inspection Process
-
Document Review
Verification of design drawings, firestop system selection plans, product technical data, test reports, and contractor self-inspection records. -
On-Site Inspection
Conducted by experienced inspectors through visual checks, supplemented by non-destructive or minimally destructive testing when necessary, to confirm material usage, dimensions, support fixation, and continuity. -
Compliance Assessment
Comprehensive evaluation of construction quality and system suitability based on ASTM, CNS, or client contract specifications. -
Reporting and Labeling
Upon passing inspection, an official IAS/ILAC inspection report is issued, and a firestop inspection label is affixed at compliant locations, providing visible proof of quality.
