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 clean rooms 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). |
