For a material to be considered non-combustible, it must pass the ASTM E 136 test at what temperature?

The ASTM E 136 test is essential for determining the combustibility of materials used in construction and safety applications. For a material to be classified as non-combustible according to this standard, it must not ignite or contribute to the combustion process when subjected to high temperatures. The correct threshold for passing the ASTM E 136 test is 750 degrees Celsius. This temperature signifies that materials meeting this criterion can withstand exposure to heat without igniting, making them suitable for environments where fire resistance is critical.

Understanding the importance of the 750 degrees Celsius benchmark helps ensure that materials used in construction and safety comply with national standards, thus providing adequate fire safety for buildings and structures.
