What is FM4882 Standards?
FM4882 is a new standard of interior wall materials for clean room, developed by FM Global and the current FM4880 standard, “Class 1 Fire Rating of Insulated Wall or Wall and Roof/Ceiling Panels, Interior Finish Materials or Coatings, and Wall Systems.” Additionally, Class1 is required on ASTM E84 standard which is “Standard Test Method for Surface Burning Characteristics of Building Materials”
FM 4882 is applied to products used as interior wall materials for cleanrooms in the pharmaceutical and food processing plants, and this standard intends to minimize the possible safety hazards and risks, in the event of an unexpected fire (to suppress the spread of fire and minimize possible damage due to smoke generation).
FM4882 standard = FM4880 standard + ASTM E84 standard + 16ft High parallel panel test.
Those products that pass the tests specified below in both standards are listed as FM4882 approved products.
