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
