Competent statistical assistance is recommended for the investigation of bias. Add to Alert PDF.

This test method covers a procedure for determining the extractable material on most fibers, yarns, and fabrics.

See Sections 6 and 7. Note 1 Other standards for the determination of extractable matter in textiles made of specific fibers include: In case of a dispute arising from differences in reported test results using this test method for acceptance testing of commercial asttm, the purchaser and the supplier should conduct comparative astmm to determine if there is a statistical bias between the laboratories.

Option 2 uses room temperature and extraction funnels. As a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and which are from a lot of material of the type in question.

No other units of measurement are included in this standard. Competent statistical assistance is recommended for the investigation of bias. Please first verify your email before subscribing to alerts. If a bias is found, either its cause must be found and corrected, or the purchaser and supplier must agree to interpret future test results with consideration to the known bias. This standard is also available to be included in Standards Subscriptions. This test method is used for the determination of the amounts of naturally present oily or waxy impurities that have not been completely removed from textiles made from animal fibers, and for the determination of the amounts of oily or waxy finishing materials applied to raw materials or textiles during manufacture.

The average results from the two laboratories should be compared using appropriate statistical analysis and a probability level chosen by the two parties before the testing begins.

Note 1-Other standards for the determination of extractable matter in textiles made of specific fibers have been published by ASTM: As the voice of the U. Option 2 uses room temperature and extraction funnels.

ASTM D – Standard Test Method for Extractable Matter in Textiles

Standards Subsctiption may be the perfect solution. Extractables by mass loss is frequently used for textiles which have a relatively large amount of extractable material to effect a significant mass change. Option 1 uses heat and Soxhlet extraction apparatus.

D227 3 uses either Option 1 or Option 2 extraction but provides for calculation of extractable matter from the loss in mass of the material due to the extraction rather than the extractable matter residue. Option 2 uses room temperature and extraction funnels. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
