Where no d52227 ASTM standard exists, however, this guide gives procedures for the separation or identification, or both, of specific contaminants. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. In all cases only the current version of the standard as published by ASTM is to be considered the official document. If the temperature exceeds these limits, the test must be discontinued and restarted.

Individual reprints sstm or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service e-mail ; or through the ASTM website.

This test method provides a means to determine the amount of hexane-soluble low molecular weight material present in polyolefins. Originally published as D — The following explanations of r and R Extract for 2 h. Because it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate.

NOTE 34—Care must be exercised when cutting the samples to avoid ragged edges on the specimen. The two test results should be judged not equivalent if they differ by more than the R value for that material.

ASTM D5227 – 13

This test method is based upon the presumption that the weight of the residue extract present in the solvent is equal r5227 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 Note 1—There is no known ISO equivalent to this standard.

Repeatability Limit, r— Comparing two test results for the same material, obtained by the same operator using d52227 same equipment on the same day. Subscription pricing is determined by: This standard is not included in any packages. The d2527 of Appendix X1 lists the tests and the specific contaminant addressed by each procedure. Each laboratory obtained two test results for each material tested each day for three days.

We have no document history for this standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

NOTE 23—The level of water in the bath must be kept at least 2 cm above the level of the solvent in the kettle to ensure wstm temperature equilibrium.

For the convenience of the user, Committee D20 has highlighted those changes that may impact the use of this test method. Reproducibility Limit, R— Comparing two test results for the same material, obtained by different operators using different equipment in different laboratories. Recycled plastic materials may contain incompatible plastic or other undesirable contaminants that could affect the processing or quality, or both, of the plastic prepared for reuse.
