The analysis scheme based on solubility is very reliable. If the document is revised or amended, you will be notified by email. Insoluble specimens may be removed from the solvent, rinsed in distilled water, and used for subsequent analyses, if required by limited sample size.

ASTM D – 12 Standard Test Methods for Identification of Fibers in Textiles

Subscription pricing is determined by: Interpretation of Results ASTM International takes no position respecting the validity of any aatm rights asserted in connection with any item mentioned in this standard.

The analysis scheme based on solubility is very reliable.

These procedures should be carried out in a hood and the laboratory adequately ventilated. Many generic classes of fibers are sold with a variety of cross-section shapes designed for specific purposes.

Standards Subsctiption may be the perfect solution. It is the responsibility of the user of f276 standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Securely tie the ends of the skein and cut off the free ends. Fiber density is the extrapolated apparent density at zero time. Please first verify your email before subscribing to alerts. Using a stirring rod, vigorously agitate the sample to remove occluded air. Apparatus, Reagents, and Materials Many of the generic classes of man-made bers are produced by several manufacturers and sold under various trademark names as follows Note 1: The listed values are for specic bers which warrant the highly precise values given.

ASTM D276 – 12

An interlaboratory study has been organized. E Ethylene glycol type. I p-ethylene oxybenzoate type. The precision and bias of the nonstandard quantitative test methods described are strongly influenced by the skill of the operator.

This standard has been approved for use by agencies of the Department of Defense. Test Method 20 for Identication of Fibers in Textiles2 3.

The list does not include examples of bers from two or more generic classes v276 polymers spun into a single lament. These test methods are not recommended for acceptance testing of commercial shipments because of the qualitative nature of the results and because of the limitations previously noted.

The infrared technique is a useful adjunct to the solubility test method. Dyes, lubricants, and delustrants are not present normally in amounts large enough to interfere with the analyses.

This standard is also available to be included in Standards Subscriptions. The method is often very difficult, and many of the phenomena observed when viewing bers with polarized light are subject to misinterpretation. Dyes, lubricants, and delustrants are not present normally in amounts large enough to interfere with the analyses. Your Alert Profile lists the documents that will be monitored. The other methods, especially microscopical examination are generally not suitable for positive identification of most man-made fibers and are useful primarily to support solubility and infrared spectra identifications.

It is possible for such modications to interfere seriously with the analyses used in these test methods.

Already Subscribed to this document. A superscript epsilon indicates an editorial change since the last revision or reapproval.

The precision and bias of the nonstandard quantitative test methods described are strongly influenced by the skill of the operator. KodelT p-ethylene oxybenzoate type: Many fibers are chemically modified by their producers in various ways so as to alter their properties.
