In the construction industry, the combustibility of building
materials is a critical factor that directly impacts the safety and
integrity of structures. The Customized Combustibility Testing
Equipment for Building Materials Testing is a revolutionary tool
that enables architects, engineers, builders, and material
manufacturers to make informed decisions regarding the fire safety
of their projects. The Customized Combustibility Testing Equipment for Building
Materials Testing is a state-of-the-art apparatus designed to
evaluate the combustibility characteristics of a wide range of
building materials. It serves as an essential asset for
construction companies, building material suppliers, research
institutions, and regulatory bodies. The primary objective is to
determine parameters such as ignition time, flame spread rate, heat
release rate, smoke production, and the residual char formation of
building materials when exposed to fire. This data is crucial for
ensuring compliance with building codes and standards, as well as
for developing innovative and safer building materials. - Robust and Heat-Resistant Construction
- The equipment is built with a heavy-duty steel frame that can
withstand the extreme temperatures and mechanical stresses
associated with combustibility testing. The interior chamber is
lined with high-temperature refractory materials, capable of
withstanding temperatures up to 1500°C. The access doors are made
of thick, insulated steel plates with a reliable sealing mechanism
to prevent heat and smoke leakage. A heat-resistant viewing window,
made of tempered glass or a transparent ceramic material, allows
for visual inspection during the test without compromising the
integrity of the test environment.
- Precision Temperature and Flame Control
- Temperature Control: The equipment can precisely regulate the
temperature within the testing chamber, ranging from ambient
temperature to 1200°C, with an accuracy of ±2°C. It utilizes
high-quality heating elements, such as silicon carbide heaters, and
a sophisticated PID (Proportional-Integral-Derivative) control
system. Multiple thermocouples are strategically placed to ensure
uniform temperature distribution and accurate temperature
monitoring. The control panel allows for the programming of complex
temperature profiles, including ramping, holding, and cycling, to
mimic different fire scenarios and temperature gradients that a
building might experience during a fire.
- Flame Generation and Control: The flame system is highly
adjustable. It can produce flames of varying intensities, from a
gentle pilot flame to a powerful, turbulent flame. The fuel supply,
which can be propane, methane, or other combustible gases, is
precisely metered using high-precision flow regulators. The
air-fuel ratio can be adjusted within a wide range, allowing for
the customization of the flame's oxidizing or reducing
characteristics. This flexibility is crucial for testing the
response of building materials to different types of flames, such
as the slow-burning flames of a smoldering fire or the intense heat
of a flashover.
- Advanced Instrumentation and Data Acquisition
- The equipment is equipped with a comprehensive suite of sensors and
measurement devices. In addition to temperature and flame sensors,
it includes optical sensors for monitoring flame height,
luminosity, and color. Smoke density sensors, based on light
scattering or absorption principles, accurately measure the amount
and density of smoke produced. Gas sensors are incorporated to
detect and analyze the composition of gases emitted during
combustion, such as carbon monoxide, carbon dioxide, and volatile
organic compounds. These sensors are connected to a high-speed data
acquisition system that records and stores all relevant data. The
data acquisition system offers a sampling rate of up to 8000
samples per second, ensuring that even the most transient and
minute changes in parameters are captured. The collected data can
be analyzed in real-time or retrieved later for in-depth studies
using specialized software, which provides detailed reports and
graphical representations of the test results.
- Versatile Testing Modes and Configurations
- The equipment offers a variety of testing modes tailored for
building materials. It can perform horizontal and vertical flame
spread tests on materials such as wallboards, flooring, and roofing
materials, simulating how fire would spread across surfaces. Cone
calorimeter tests can be carried out to measure the heat release
rate and other combustion parameters of samples under a controlled
radiant heat flux, which is crucial for understanding the fire
behavior of insulation and other combustible building components.
It can also conduct fire resistance tests on structural elements
like columns, beams, and walls, evaluating their ability to
maintain load-bearing capacity and integrity during a fire.
Additionally, the equipment can be configured to test the
effectiveness of fireproof coatings and sealants by measuring the
improvement in combustibility of the underlying materials.
- Compliance with Building Fire Safety Standards
- The Customized Combustibility Testing Equipment is designed to
comply with a multitude of international and national building fire
safety standards. It adheres to ASTM (American Society for Testing
and Materials) standards, such as ASTM E84 for surface burning
characteristics, ASTM E1354 for heat and visible smoke release
rates, and ASTM E662 for smoke density. It also meets ISO
(International Organization for Standardization) standards,
including ISO 5660 for reaction-to-fire tests and ISO 1716 for
calorific value determination. This compliance ensures that the
test results are widely recognized and accepted by building
regulatory bodies and industry peers, facilitating product
certification and use in construction projects.
- Chamber Size and Capacity
- The equipment is available in different chamber sizes to suit
various building material samples and testing requirements. Smaller
chambers may have interior dimensions of 0.5 meters x 0.5 meters x
0.5 meters, suitable for testing small specimens like samples of
fireproof coatings or individual pieces of insulation. Medium-sized
chambers can measure 1 meter x 1 meter x 1 meter, providing
sufficient space for testing larger building materials or a batch
of similar components. Larger chambers, with dimensions exceeding 2
meters x 2 meters x 2 meters, are ideal for full-scale testing of
structural elements or assemblies. The interior volume and shape
are carefully designed to ensure proper air circulation and uniform
exposure of the sample to the fire and environmental conditions.
- Temperature Range and Accuracy
- As mentioned earlier, the temperature can be controlled from
ambient to 1200°C, with an accuracy of ±2°C. The temperature ramp
rate can be adjusted from 1°C per minute to 80°C per minute,
allowing for the simulation of both slow and rapid temperature
changes. For example, a slow ramp rate may be used to study the
thermal degradation of a building material over time, while a rapid
ramp rate can mimic the sudden heat increase during a fire
outbreak.
- Flame Intensity and Control Parameters
- The flame intensity can be adjusted over a wide range, with a
maximum heat output equivalent to several megawatts per square
meter. The fuel flow rate can be varied from a few milliliters per
minute to several liters per minute, and the air-fuel ratio can be
precisely controlled within a range of 1:1 to 18:1. These
parameters enable the creation of flames with different
characteristics, from a small, stable flame for precision testing
to a large, turbulent flame for more severe fire simulations.
- Data Acquisition Rate and Resolution
- The data acquisition system samples sensor data at a rate of 8000
samples per second. The temperature sensor has a resolution of
0.1°C, the smoke density sensor can detect changes as small as
0.01% opacity, and the gas sensors have a sensitivity in the parts
per million (ppm) range for most common gases. This high-resolution
and high-speed data capture ensure that the equipment provides
detailed and accurate information about the combustibility of the
tested building materials.
- Compliance with Key Building Fire Testing Standards
- The equipment complies with ASTM E84, ASTM E1354, ASTM E662, ISO
5660, and ISO 1716, among other relevant standards. It can also be
customized to meet specific requirements of other building industry
standards or regulatory codes, ensuring its adaptability to
different construction applications and local building regulations.
- Accurate Evaluation of Building Material Combustibility
- The primary function of the equipment is to provide a highly
accurate and realistic simulation of fire conditions for building
materials. By precisely controlling temperature, flame
characteristics, and other environmental factors, it allows for the
comprehensive assessment of how materials will behave in an actual
building fire. For example, it can determine if a particular
insulation material will contribute to the spread of fire, if a
steel structure will maintain its strength under high temperatures,
or if a fireproof coating will effectively reduce the
combustibility of a substrate. This information is invaluable for
architects and engineers to select the most suitable materials and
design safer building structures.
- Enhanced Building Design and Material Selection
- Through detailed combustibility testing, construction professionals
can make informed decisions about material selection and building
design. If a material shows a high flame spread rate or excessive
smoke and toxic gas production, alternative materials can be
considered. For example, if a wooden panel has a poor
combustibility performance, a fire-retardant-treated version or a
non-combustible substitute can be chosen. This leads to the
development of more fire-resistant building designs, reducing the
risk of fire damage and ensuring the safety of occupants.

insulation. The tests revealed that the material had a relatively
high heat release rate and significant smoke production. By
reformulating the material and adding fire retardants, they were
able to reduce the heat release rate by 50% and minimize smoke
production, making it a more suitable option for building
insulation and meeting the required fire safety standards.
- Evaluation of Fireproof Coatings for Steel Structures
- A construction company tested different fireproof coatings on steel
beams using the equipment. The results showed that one particular
coating was able to increase the fire resistance of the steel beams
by an additional 30 minutes compared to a standard coating. This
