ASTM D5227 – 13
Appendix X1 lists the tests and the specific contaminant addressed by each procedure. The two test results should be judged not equivalent if they differ by more than the r value d52227 that material.
Units used in 21 CFR Your Alert Profile lists the documents that will be monitored. This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version.
Replace the kettle head with condenser column. This test v5227 provides a means to determine the amount of hexane-soluble low molecular weight material present in polyolefins. The FDA protocol also states the temperature of the contents must be brought to 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.
Each test result was an individual determination. This guide lists existing ASTM and ISO methods plus currently practiced industrial techniques for identification and classification of contaminants in recycled plastics flake or pellets. 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.
Units used in 21 CFR Recycled plastic materials may contain c5227 plastic or other undesirable contaminants that could affect the processing or quality, or both, of the ast prepared for reuse.
Each laboratory obtained two test results for each material tested each day for three days. If the document is revised or amended, you will be notified by email. Historical Version s – view previous versions of standard.
Note 1 — There is no known ISO equivalent to this standard. We have no amendments or corrections for this axtm. If the temperature exceeds these limits, the test must be discontinued and zstm.
Techniques to separate and identify incompatible plastics, moisture, chemicals, or original product residues, and solid contaminants such as metals, paper, glass, and wood are essential to the processing of recycled plastic materials.

This test method is a modification of the Food and Drug Administration FDA procedure for determining hexane extractables of polyolefins. An American National Standard Designation: Note 1—There is no known ISO equivalent to this standard. In all cases only the current version of the standard as published by ASTM is to be considered the official document.

Repeatability Limit, r— Comparing two test x5227 for the same material, obtained by the same operator using the same equipment on the same day. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. This standard is also available to be included in Standards Subscriptions.
Standard Test Method for Measurement of Hexane Extractable Content of Polyolefins
D — A number in parentheses indicates the year of last reapproval. Precision and Bias 12 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 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 d52227 complex and time-consuming evaporation process described in 21 CFR Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
