Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement d267 such rights, are entirely their own responsibility. A selective solvent refer to Table 1 of Test Methods D can be very useful in these cases, if one can be found.

Differences in tenacity, linear density, bulkiness, or the presence of inert delustrants normally do adtm interfere with analytic tests, but chemical modifications for such purposes as increased dyeability with certain dyestuffs may affect the infrared spectra and some of the physical properties, particularly the melting point.

Link to Active This link will always route to the current Active version of the standard. 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.

Unless otherwise indicated, it is intended that all reagents shall conform to f276 specications of the Committee on Analytical Reagents of the American Chemical Society, where such specications are available. It is possible for such modifications to interfere seriously with the analyses used in these test methods.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Considerable experience and diligence of the analyst may be necessary to resolve satisfactorily these difficulties. It is desirable to have available authentic samples of the bers to be identied, and it is essential to have v276 that are unfamiliar.

Please first log in with a verified email before subscribing to alerts.

Standard Test Methods for Identification of Fibers in Textiles

Subscription pricing is determined by: 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.

NOTE 5—The internal reection spectroscopy technique is more difficult to use satisfactorily than the KBr disk or lm techniques and it is not recommended for use except by an operator experienced in the technique.

Considerable experience and diligence of the analyst may be necessary to resolve satisfactorily these difficulties.

The longitudinal and cross-section photographs of the various bers have been omitted since they are published elsewhere and the usefulness for identication is limited. This standard has been approved for use by agencies of the Department of Defense.

These test methods are a generally reliable means of identifying the generic types of fibers present in a axtm of textile material of unknown composition.

These differences will be evident upon microscopical examination of the fiber and may interfere with the measurements of refractive indices and birefringence. D — 00a FIG. Place the specimen in the sample beam of the instrument and record the spectrum while scanning from 2. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

C Some modarylic bers cannot be distinguished from acrylic bers in this solubility scheme. This standard is also available to be included in Standards Subscriptions.

ASTM International takes no position astj the validity of any patent rights asserted in connection with any item mentioned in this standard. I p-ethylene oxybenzoate type.

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. If the document is revised or amended, you will be notified by email. The methods have been revised completely, emphasizing infrared spectroscopic techniques for identifying man-made ber types.

Record the weight of the wire hook, H, to the nearest 0. Other techniques such as, microscopical examination or comparison of physical properties are used to conrm the identication or to distinguish between those ber classes anidex, aramid, asbestos, uorocarbon, glass, and novoloid which are not dissolved by any of the reagents used in this scheme.

The bers should be watched during the test to determine whether there might be a mixture of ber types, some of which are soluble and some insoluble. We have no amendments or corrections for this standard.

It is possible to make an identication using a sample of less than 10 mg of each type of ber present. This listing is not meant to exclude other ber types or to restrict the choice of alternative solvents.
