A fire resistance test procedure is a full-scale furnace test: an element of construction is built into a restraint frame, loaded if it is loadbearing, heated along a standard time-temperature curve, and monitored until it fails one of three criteria or survives the required exposure period. The three criteria are loadbearing capacity (R), integrity (E) and insulation (I). This guide walks the procedure through in the order a laboratory runs it - the standard fire curves, the specimen and conditioning stages, the instrumentation that decides the result, the exact pass and fail thresholds, the element-specific parts of EN 1364, EN 1365, EN 1634 and EN 13381, and the calibration and direct-application rules that decide how far a single test result can be used.

The non-combustibility test decides whether a material can be declared non-combustible at all. This guide covers the 750 C furnace procedure, the pass criteria used in Europe, North America, China and marine work, and how to specify an apparatus that still meets the editions now in force.

Reaction to fire testing explained: the four EN 13501-1 tests, the class each route needs, and the BRT equipment for EN ISO 1182, 1716, 11925-2 and EN 13823.
