ASTM D88 standard test method for Saybolt viscosity
11. Calculation and Report
11.1 Multiply the efflux time by the correction factor for the viscometer determined in 9.2.
11.2 Report the corrected efflux time as the Saybolt Universal or Saybolt Furol viscosity of the oil at the temperature at which the test was made.
11.2.1 Report values below 200 SUS or SFS to the nearest 0.1 s. Report values of 200 s or higher to the nearest whole second.
12. Precision and Bias
12.1 Results should not differ from the mean by more than the following (see Note 5):
12.1.1 Repeatability (one operator and apparatus) - 1 %.
12.1.2 Reproducibility (different operators and apparatus) - 2 %.
NOTE 5 - For petroleum products, the precision and bias is based on data from Test Method E 102. For emulsion, use precision and bias statement in Test Method D244, Section 38.
