The phrase "accurate standard of" is correct and usable in written English.
It can be used when discussing a benchmark or criterion that is precise and reliable for measuring or evaluating something.
Example: "To ensure quality control, we must establish an accurate standard of measurement for our products."
Alternatives: "reliable benchmark of" or "precise criterion for".
Hysteroscopy is widely accepted to be the accurate standard for investigation of the uterine cavity [1, 2].
They are the single most widely used measure of nutritional status because of their precision, replicative nature and the availability of accurate standards for comparison.
By averaging the values of multiple samples, more accurate standard deviation and maximum of aerodynamic loads can be obtained.
We also used robust modeling techniques which allowed for the assessment of the relative contributions of individual- and neighborhood-level characteristics as well as the estimation of more accurate standard errors than those produced using standard modeling techniques.
The sample size was calculated to allow sufficiently accurate standard errors for the estimated parameters of the factor analysis.
1 There is still no accurate standard reference range for the characteristics of abdominal cavity drainage fluid after surgery for gastrointestinal or retroperitoneal tumors, and thus clinical laboratories can only borrow the reference range of serous cavity effusion.
In high-income countries, consumption expenditure patterns are very complex and income can be a better measure, and in developing countries, where formal employment is less common and home production widespread, consumption expenditure can be a more accurate measure of living standards [ 48].
In one last, Panglossian twist, he chose to follow not the standard — and roughly accurate — measure of a degree developed by the Greeks but a slightly lower figure, which had been put forward by the ninth-century Arab astronomer Al-Farghani.
An accurate standard-map approach, instead of the approximate standard-map approach, is developed for the analytical prediction of the onset of a new resonant overlap forming a new resonant-separatrix web in the stochastic layer.
