Frequently Asked Question (FAQ)

What is a Fire Resistance Test Furnace?

A Fire Resistance Test Furnace is an apparatus that helps evaluate the fire resistance of a horizontal or vertical construction such as walls and glazed structures, floors and ceilings, beams, columns, doors, shutters, ceilings, ducts, cable glands and fire dampers. Testing can be done with either vertical or horizontal load.

To prevent the spread of fire within the built environment and to maintain means of escape, building legislation across the world often requires that separating elements, such as partitions, doors and glazed screens, offer known resistance to fire exposure.

What is Fire Endurance?

Fire endurance is defined by ASTM as a measure of the elapsed time during which a material or assembly continues to exhibit fire resistance under specified conditions of test and performance.

What does a 2-hour fire rating mean?

When a building or system is said to have a 2-hour fire rating, what does that mean? It means that the system has satisfied the requirements for a 2-hour rating specified in a relevant standard test.

What different types of Fire Resistance Test Furnaces are available?

With different types of furnaces on the market, it can be overwhelming for you to determine what type is best for your needs. One popular choice is our Hydraulic Tilting Type Combination Furnace which can be set up to test either a Full Scale Vertical specimen or Horizontal specimen in less than 30 minutes, eliminating the need for two separate furnaces. Other types of furnaces include a 3D Box type Rectangular Furnace, a stand alone Vertical Furnace, Horizontal Furnace, Intermediate Furnace, Indicative Furnace and Mini Furnace. Test specimen size that can be tested using the above furnaces ranges from 500mm x 500mm to 5000mm x 4000mm, depending on selected models.

I am a Fire Door manufacturer, looking into the feasibility of installing a Fire Resistance Test Furnace for my own in house use. I am planning to test my product once every week. Will I be able to recover my investment within 5 years?

Most commercial Fire Testing Houses carry out fire resistance tests upwards of 120 tests per year. On average, the return on investment is between 7 to 9 years.

What is the operating life of a Fire Resistance Test Furnace?

That’s a great question! The answer really depends on the amount of maintenance that is completed as the furnace gets older. With the right approach, furnace casing and combustion system can last from 40 -50 years. The average life of  the refractories is between 6 to 8 years based on an average of 120 tests per year, before replacement is required. Make sure to call us to learn about our maintenance programs to help save on every service call!

What type of infrastructure is needed to support the operation of a Fire Resistance Test Laboratory?

  1. Indoor space with high roof between 8 to 12 metres, strong floor designed for 25 kN/m2
  2. Gas supply (Propane or Natural Gas, 140 kPa)
  3. Electricity supply, 3 phase, 50 Hz, from 60 Amperes to 200 Amperes depending on selected furnace chamber size
  4. Storage space for Test Specimen Frames, building materials to erect supporting construction, test specimen etc
  5. Open Space for Gas Tank Farm, 50 to 60 m², setback distance from building 7.5 metres, 200 Amperes, 3 phase, 50Hz supply
  6. Wide and High shutter doors for laboratory building to allow unloading of building materials by small trucks
  7. Flue Gas Treatment System.

What if I only need Fire Testing and Product Certification services?

CMTS has installed several Vertical, Horizontal, Combination and Indicative Fire Resistance Test Furnaces in government and private owned test laboratories.

These laboratories offer ISO/IEC 17025 accredited fire tests to a variety of test standards such as Australian (AS 1530:4), British (BS 476:20 to 24),  European (EN1363-1,2)), ASTM E119, UL263 and International standards (ISO 834:1, IMO). A test report, in English, is delivered with the test results after testing.

CMTS can facilitate fire testing services for clients in ASEAN countries and beyond, and assist to connect clients to certification bodies who can provide guidance on product certification in preparation for entry into the international market.

A two-part standard, BS 8414 consists of:

i) BS 8414-1: A method for assessing the fire performance of non-loadbearing external cladding systems applied to the stonework façade of a building when exposed to an external fire under controlled conditions. The test evaluates whether a cladding system subject to fire breaking out of an open window or external wall, will result in excessive fire spread up the façade or into the building at a higher level.

ii) BS 8414-2: Similar to BS 8414-1, but in relation to fire performance of curtain-wall systems or systems incorporating glass panels fixed to and supported by a structural steel frame.

We also provide ad-hoc fire testing service for the purposes of product development. If you would like to know more, feel free to contact us! Email to [email protected] or WhatsApp +6012 – 3297000
