1. Overview

Laboratory Fire Resistance Vertical Furnace Test Of Building Structures consists of fire test furnace, control part, gas part, purification system, sample test stand, gas flow measurement system, temperature measurement system and pressure measurement and control system. Applicable to sheet metal structural parts, the fire resistance characteristics are determined under standard fire conditions. The device can be used to determine the fire resistance characteristics of the frame door, non-frame door, rolling shutter door, the fireproof glass and the like under standard fire conditions. It adopts WINDOWS XP operation interface and LabView, a global precision equipment development software. The interface style is fresh, beautiful and simple. During the test, the measurement results are displayed in real time and the perfect curve is dynamically drawn. The data can be saved, read and printed permanently, and the report can be printed directly. It has high intelligence, guided menu operation, simple and intuitive features, and makes the test results more accurate. It is suitable for the fire resistance test of load-bearing vertical partition members and non-load-bearing vertical partition members.

2. Standard
