The National Institute of Standards and Technology (NIST) has fabricated st
able, transportable 10 M Omega and 1 G Omega standard resistors for use in
an international comparison of high resistances. This fabrication process i
s being applied to the construction of standard resistors of values up to 1
0 T Omega, with initial results indicating significant improvements in stab
ility and fewer adverse effects induced by mechanical shock and vibration.
