Steel Structure Fireproof Coating Small Sample Test Furnace
Product Overview
TheSmall Sample Test Furnace for Steel Structure Fireproof Coatingis a specialized thermal testing instrument designed to evaluate the fire resistance and structural integrity of fireproof coatings on steel substrates under controlled fire conditions. It simulates real-world fire scenarios to quantify flame spread, heat resistance, and coating adhesion, ensuring compliance with international fire safety standards for steel structures.
Type: High-temperature thermal testing furnace
Test Standards: ASTM E119 (Fire resistance of structural elements), ISO 834 (Fire resistance tests), GB/T 9978 (Chinese fire resistance standard)
Key Metrics:
Fire Resistance Duration (minutes)
Surface Temperature Rise (ΔT, °C)
Coating Adhesion Strength (MPa)
Sample Size: Up to 150×150×50mm (steel plate with coating)
Key Features
Compact Design:
Optimized for small steel samples (e.g., bolts, brackets)
Lightweight (≤50kg) for lab/bench use
Advanced Features:
Real-time thermal imaging (°C gradient mapping)
AI-based coating degradation analysis
Programmable multi-stage fire cycles
Compliance:
ASTM E119 (Fire resistance rating)
ISO 834-1 (Standard fire curve)
GB/T 9978.1 (Chinese fire resistance test)
Applications
Construction:Testing fireproof coatings on steel beams/columns
R&D:Developing high-temperature-resistant coatings
Quality Control:Batch inspection of pre-coated steel components
Forensic Analysis:Evaluating fire damage to structural elements
Standard Operation Workflow:
Sample Preparation: Mount steel plate with coating in sample holder
Parameter Setup: Select fire curve (e.g., ISO 834 standard)
Testing: Initiate heating cycle (e.g., 1-hour fire resistance test)
Analysis: Measure temperature rise and coating integrity
Cleaning: Automated ash removal system
