Homework Answer on Engineering Design Practice

What is Fire Resistance Testing?

Different materials have to be tested to determine their ability to withstand all risks and threats related to fires, such as temperatures, insulation, structural integrity, among other strength parameters. All these parameters are important to ensure that the materials maintain their functionality or usability long and strongly enough for people, systems, or buildings to be safeguarded. Therefore, to understand the ability of a product to withstand fire, a fire resistance test is performed (ASTM E119-14 12).

Such a trial involves a series of tests performed on a product to determine its optimal functionality under extreme and real fire conditions such as temperature, pressure, and time of fire.An optimal fire test is not only reliant on buildings and their fire resistant capabilities, but on such materials and products as electrical systems and appliances, civil and structural components, mechanical systems, components, and accessories, among many others.Some of the types of fire resistance tests performed on products and systems include:
