Standard Test Methods for Quantitative Analysis of Textiles (Withdrawn 2024)
SIGNIFICANCE AND USE
5.1 Qualitative and quantitative fiber identification is actively pursued by committee RA24 (Fiber Identification) of AATCC and presented in AATCC Test Methods 20 and 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, D13.51 has agreed Test MethodsD276 and D629 will be maintained as active standards by ASTM.
5.2 Test Methods D629 for the determination of quantitative analysis of textiles may be used for acceptance testing of commercial shipments but caution is advised since information on between-laboratory precision is lacking. Comparative tests as directed in 5.2.1 or in Standard Tables D1909 may be advisable.
5.2.1 In case of a dispute arising from differences in reported test results using Test Methods D629 for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. 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. The test specimen should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student's t-test and an acceptable probability level chosen by the two parties before the testing began. 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 in the light of the known bias.
5.3 The effects of the various reagents used in the chemical methods on the residual fibers in a blend depend upon the history of the fibers and, unless otherwise stated, are generally too small o...
SCOPE
1.1 These test methods cover procedures for the determination of the fiber blend composition of mixtures of the fibers listed in 1.2. Procedures for quantitative estimation of the amount of moisture and certain nonfibrous materials in textiles are also described, for use in the analysis of mixtures, but these are not the primary methods for the determination of moisture content for commercial weights.
1.2 These test methods cover procedures for the following fiber types:
1.2.1 Natural Fibers:
1.2.1.1 Cellulose-Base Fibers:
Cotton
Hemp
Flax
Ramie
1.2.1.2 Protein-Base Fibers:
Animal hairs (other than wool)
Silk, cultivated
Silk, Tussah
Wool
1.2.2 Man-Made Fibers:
1.2.2.1 Cellulose-Base Fibers:
Acetate (secondary)
Rayon, viscose or cuprammonium
Triacetate
1.2.2.2 Synthetic-Base Fibers:
Acrylic
Aramid
Modacrylic
Nylon 6, Nylon 6-6, others
Olefin
Polyester

This standard is issued under the fixed designation D629; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision.Anumber in parentheses indicates the year of last reapproval.A

INTRODUCTION
Methods D629-59 T, Quantitative Analysis of Textiles, were discontinued in 1969 because the
responsible subcommittee failed to recommend their adoption as a standard after several years of
publication as a tentative. The subcommittee action was based on the members’ knowledge that the
standard did not include several fiber types introduced to the textile trade after the method was
published, and that the techniques required for their identification were lacking in the text, allowing
it to become out of date. The procedures included in the text, however, are believed to be reliable for
the fiber types named and the techniques described are currently being used in the trade and are
referenced by other standards sponsored by Committee D-13 onTextiles. Reinstatement as a standard
using the previously assigned number was requested since the listed procedures were reliable and the
text considered to be the best available, though not all inclusive. Extensive editorial changes were
madeinvarioussectionsin1972,andthemethodswerereinstatedasD629-72.Editorialchangeshave
again been made throughout the text, and statements on precision and bias and suitability for
acceptance testing have been added.
