Clean Room Standards
According to the United States specification FED-STD-209D, Classes of cleanliness are defined by
the number of particles per cubic foot.
Particle sizes shown in the following table.
Measured Particles Size (Microns)
Note!
*Features for IFR models
The design action of the standard CRS cammed screwdrivers is such that when the tool reaches its preset torque value the mechanism disengages from the drive thus limiting the torque applied. Further rotation of the screwdriver handle resets the mechanism ready for the next torquing operation. The IFR models eliminates any small reaction during resetting.
All IFR models are "impact free" when the cam resets.
Screwdriver is torque limiting in the CW direction only.
CCW operation available upon request.
Tamper-proof internal adjustment. No external adjustment scale - must be preset using a torque analyzer.
