Scope

These test methods are a generally reliable means of identifying the generic types of fibers present in a sample of textile material of unknown composition. The methods are generally not useful for distinguishing fibers of the same generic class from different manufacturers or for distinguishing different fiber types of the same generic class from one producer.

Many fibers are chemically modified by their producers in various ways so as to alter their properties. It is possible for such modifications to interfere seriously with the analyses used in these test methods. Considerable experience and diligence of the analyst may be necessary to resolve satisfactorily these difficulties.

Dyes, lubricants, and delustrants are not present normally in amounts large enough to interfere with the analyses.

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.

Note 28212;For statements on precision and bias of the standard quantitative test methods for determining physical properties for confirmation of fiber identification refer to the cited test method. The precision and bias of the nonstandard quantitative test methods described are strongly influenced by the skill of the operator. The limited use of the test methods for qualitative identification cannot justify the effort that would be necessary to determine the precision and bias of the techniques.

5.5 Qualitative and quantitative fiber identification is actively pursued by Committee RA24 (Fiber Identification) of AATCC and presented in AATCC Test Method 20 and Test Method 20A. Since precision and bias development is also part of the AATCC test methods, both AATCC and ASTM D13 have agreed that new development will take place in RA24. However, because there is valuable information still present in the ASTM standards, Test Methods D276 and D629 will be maintained as active standards by ASTM.

1.1 These test methods cover the identification of the following textile fibers used commercially in the United States:

Acetate (secondary)	Nylon
Acrylic	Nytril
Anidex	Olefin
Aramid	Polycarbonate
Asbestos	Polyester
Cotton	Ramie
Cuprammonium rayon	Rayon (viscose)
Flax	Saran
Fluorocarbon	Silk
Glass	Spandex
Hemp	Triacetate
Jute	Vinal
Lycocell	Vinyon
Modacrylic	Wool
Novoloid

1.2 Man-made fibers are listed in 1.1 under the generic names approved by the Federal Trade Commission and listed in Terminology
