Traceability and conformance
Measurements should be done by using Cargille Refractive Index Liquids with
stated in accuracy of ±0.0002 R.I.
Cargille Index of Refraction Liquids are manufactured and calibrated using
instruments whose accuracy is verified by daily comparision to N.I.S.T. (N.B.S.)
traceable standards. N.I.S.T. standards are based on angle measurements using
a Wild divided circle spectrometers.
