Fireproof
Fireproof is a term used to describe materials or products designed to resist or delay the effects of fire. In formal safety terminology, the term is discouraged because no material is guaranteed to be completely impervious to fire. Instead, engineers use fire-resistant or fire-rated to describe a material's performance under standard fire exposure. Fire resistance is specified by a time-based rating (for example, 1-hour or 2-hour), indicating how long an element can withstand a standard fire curve while limiting heat transfer, maintaining structural integrity, or preventing the passage of flames.
Common fire-resistant materials and systems include concrete and masonry, mineral wool insulation, cementitious or intumescent fireproofing
Standards and testing: Performance is verified in standardized tests such as ASTM E119 for building assemblies,
Limitations and considerations: Fire-resistant does not guarantee safety under all conditions; rated assemblies must be correctly
