Plastic sheets clss 94 rating.

Ul 94 5v is a test standard for materials which are already classified as ul 94 v 0. Plastic products for ul 94 flame class. Slow burning on a horizontal part. High density polyethylene hdpe low density polyethylene ldpe polypropylene sheet rod and tube.

This is the highest and most flame retardant level of the ul 94 ratings. There are 6 flame classifications specified in ul 94 that are assigned to materials based on the results of these small scale flame tests. Ul 94 the standard for safety of flammability of plastic materials for parts in devices and appliances testing is a plastics flammability standard released by underwriters laboratories of the united states. The standard determines the material s tendency to either extinguish or spread the flame once the specimen has been ignited.

Fire rated polycarbonate sheet is a flame inhibiting uv stable plastic sheeting and glazing product that is virtually unbreakable. Overview of ul 94 flame classifications. Using kydex sheet also results in considerable cost savings for retailers because it is extremely resistant to chipping and breaking from in store traffic and during shipping. It is a more stringent test than ul 94 v 0 in several ways.

The first determines the material s tendency either to extinguish or to spread the flame once the specimen has been ignited. The testing is conducted on bar and plaque specimens using a larger flame height than in vertical testing 125mm vs 20mm. Polycarbonate clear plastic sheet 12 x 18 x 0 0625 1 16 shatter resistant easier to cut bend mold than plexiglass. Flame retardant fr high service temperature plastics fm4910 ul94 v 0 and semiconductor materials naics code 333242 our fm 4910 listed and ul 94 v 0 classified materials are commonly used in wet bench manufacturing semiconductor manufacturing and computer chip manufacturing where contamination from even small amounts of smoke can destroy the integrity of components.

Flame retardant polycarbonate sheets. Burning stops within 30 seconds on a vertical part allowing for drops of plastic that are not inflames. Ac plastics is proud to offer makrolon low flammability lf plastic sheeting solutions. Ul 94 the standard for safety of flammability of plastic materials for parts in devices and appliances testing there are two types of pre selection test programs conducted on plastic materials to measure flammability characteristics.

Ul 94 rating definition of rating. Burning stops within 30 seconds on a part allowing for drops of vertical flammable plastic. Overview of fr materials fr materials fire retardant materials are classified based on ul 94 flame classifications of each material. By robosource 9 95 9.
