The two test results should be judged not equivalent if they differ by more than the R value for that material. A number in parentheses indicates the year of last reapproval. If the temperature exceeds these limits, the test must be discontinued and restarted.
ASTM D – 13 – Standard Test Method for Measurement of Hexane Extractable Content of Polyolefins
Reproducibility Limit, R— Comparing two test results for the same material, obtained by different operators using different equipment in different laboratories. Precision and Bias 12 If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

Standard Test Method for Measurement of Hexane Extractable Content of Polyolefins
Note 1 — There is no known ISO equivalent to this standard. This test method is based upon the presumption that the weight of the residue extract present in the solvent is equal to the amount extracted from the film sample and could therefore be quantified by measuring the weight loss of the extracted film, eliminating the complex and time-consuming evaporation process described in 21 CFR Please first verify your email before subscribing to alerts.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
