ASTME84 Steiner Tunnel Test Apparatus

Motis Fire Technology (China) Co., Ltd

Product Description

Introduction:
ASTM E84 is intended to provide only comparative measurements of surface flame spread and smoke density measurements with that of select grade red oak and fiber-cement board surfaces under the specific fire exposure conditions described herein.
This test method exposes a nominal 24-ft (7.32-m) long by 20-in. (508-mm) wide specimen to a controlled air flow and flaming fire exposure adjusted to spread the flame along the entire length of the select grade red oak specimen in 51/2 min.
 
Features: The fire test chamber is exactly the same as that of UL fire lab. The fire test chamber is a rectangular horizontal duct with a removable lid. The sides and base of the chamber are lined with an insulating firebrick. One side of the fire testing chamber is provided with double quartz observation windows with the inside pane flush mounted. Multiple windows are located along the tunnel so that the entire length of the test sample is observable from outside the fire chamber. The lid is consist of a removable noncombustible metal and mineral composite structure. The lid covers the fire test chamber and the test samples maintains in an unwarped and flat condition. Two NFP elbow gas burners delivering flames upward against the surface of the test samples. Remote spark ignition mode, to ensure the safety. An air intake shutter is located upstream of the burner. Six refractory firebricks along the side walls of the chamber for proper combustion. The static pressure meter inserted through the top at the midwidth of the tunnel below the ceiling. The exhaust end is fitted with a gradual rectangular-to-round transition piece. The exhaust duct is insulated with high temperature mineral composition material. An exhaust fan is installed at the end of the exhaust duct. The air flow and draft pressure are controlled by automatically damper and Frequency converter. A photometer system consisting of a lamp and photocell mounted on a horizontal section, and with the light beam directed upward along the vertical axis of the vent pipe. Thermocouples installed inside and outside the floor of the test chamber. Data acquisition system and software. Requirements: Electrical: 115 Volts AC 60Hz / 230 Volts AC 50Hz. Electrical: 380 Volts AC, 20KW Ambient Temperature: Operating 15°C to 35°C. Gas: Methane and air compressor Utility: Crane
