8、rnm2s-. The standard is one of a series where the compounds have been graded by consideration of their torque strength and viscosities. General applications of these materials include locking and sealing threaded fasteners ; other uses include assembling slip-fitted parts. NOTE : The materials shoul

9、d not normally be used on electrical connections where the assembled connection is required to carry electrical currents. 2 Normative references This European Standard incorporates by dated or undated reference provisions from other publications.
