_*****[Per ASTM E230, Special compensating extension wires are not necessary with Type B over the limited temperature range 0° C to 50° C. Non-] compensated conductors(copper/copper) will not introduce significant error in this range. For the larger temperature gradient  of 0° C to 100° C across the extension portion of the circuit, the use of non-compensated (copper/copper) extension wires may result in small errors, which will not exceed the ASTM E230 tolerances given for measurements above 1000° C._ _******[Black on EXGG wire.]_
