BestChek cassettes meet NIOSH, OSHA and ASTM standards in Count, Clearing, Conductivity, Collection Area, and Construction (the 5 C's of asbestos cassettes)

Count

• Average background fiber count for SKC BestChek filters is less than 4 fibers per 100 fields (OSHA Method ID-160 allows up to 4 fibers per 100 fields and NIOSH 7400 permits up to 5 fibers per 100 fields).

Clearing

• SKC BestChek filter material clears thoroughly to meet method specifications and is suitable for PCM analysis.

Conductivity

• SKC BestChek cassette plastic contains over 18% carbon black for proper conductivity as tested using ASTM methods.

Collection Area
