Fire-resistance rating

A fire-resistance rating typically means the duration for which a passive fire protection system can withstand a standard fire resistance test. This can be quantified simply as a measure of time, or it may entail a host of other criteria, involving other evidence of functionality or fitness for purpose.Time/Temperature Curves used for testing the fire-resistance rating of passive fire protection systems such as firestops, fire doors, wall and floor assemblies, etc., which are used in compartmentalisation in buildings and the petrochemical industry in Europe and North America.Time/Temperature Curves used for testing the fire-resistance rating of passive fire protection systems in tunnels in Germany, The Netherlands and France.Time/Temperature Curve used for testing the fire-resistance rating of passive fire protection systems in tunnels in The Netherlands.Time/Temperature Curve used for testing the fire-resistance rating of passive fire protection systems in Europe.Time/Temperature Curve used for testing the fire-resistance rating of passive fire protection systems in tunnels in France.Time/Temperature Curve used for testing the fire-resistance rating of passive fire protection systems in tunnels in Germany.Furnace pressure is also subject to standardised tolerances for testing to obtain fire-resistance ratings. This image shows European tolerances, subject to NEN-EN 1363-1.Furnace Temperatures for fire testing to obtain fire-resistance ratings are subject to certain tolerances. This graph shows the tolerance applicable to the European building elements / cellulosic curve.MOAC: Mother of all curves “Reprinted, with permission, from E3134-17 Standard Specification for Transportation Tunnel Structural Components and Passive Fire Protection Systems, copyright ASTM International, 100 Barr Harbor Drive, West Conshohocken, PA 19428.
