testing (for both 2-class and 3-class sampling plans), 2) Variables (quantitative) testing of batches, and 3) Process control testing of processes or cross-batch testing? 6) Because dietary fibre can be determined by a number of methods that yield different results, when the Prosky method is not used the method used should be stated and the value should be identified by INFOODS tagnames  (Klensin et al., ). In addition, the method should be identified with the tagname in food composition tables.
(see BPG Spot Tests: Microchemical Testing: Sampling Technique and Sample Handling and TSG: Analysis and Testing Methods for Textiles: Fiber Identification: Microscopy) Dispersed Fiber Sample (Directly from Object) Basic steps: (done with the aid of magnification, usually 5–25x) The artifact is thoroughly examined. Test Methods D 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 or in Standard Tables D may be advisable. In case of a dispute arising.

Tensile testing is normally conducted by the material producer and the results are supplied to the user as part of the material certification sheet. Since the tensile test is a destructive test, it is not performed directly on the supplied material. For wrought materials, the test specimens are taken from the same heat or lot of material that is.

Fiber sampling from combed slivers or roving or yarns: Random draw method: This method is used for sampling card sliver, ball sliver and top. The sliver from which sample has to be taken is pulled in such a way that the end has no broken or cut fibers. Cut square method: This method is used for obtaining fibre sample from yarn.
Cut a certain length of the yarn and then untwist one of the ends of the yarn. Purchase your copy of BS as a PDF download or hard copy directly from the official BSI Shop. All BSI British Standards available online in electronic and print formats.
BS - Methods of fibre sampling for testing. Much of the information presented in this chapter focuses on some new testing methods such as quantitative fibre mixture analysis for fabrics by scanning electron microscopy (SEM), using the environmental scanning electron microscope (ESEM) method to characterize the surface, interface and Methods of fibre sampling for testing.
book properties of fabrics, computer image processing technology and so on. Measurement of Dietary Fiber - dietary fiber content in a sample is measured in the laboratory by what is called an enzymatic-gravimetric method. Measurement of Dietary Fiber - laboratory method.
Testing methods from all steps of the supply chain will be considered, from the filament, the yarn, fabrics, preforms, to the final composite. Commercially available testing device exist for this, realizing standardized test environments and procedures.
A representative selection of standardized testing methods will be : Thomas Pusch. Sampling Techniques For The Determination of Fiber Properties The sampling method used to select a fiber for testing depends upon the form in which the fiber is available. Therefore fibers in bales, in sliver, card web, yarn etc will require different techniques The test result of sample may not be the same as obtained by testing bulk sample.
Sampling the top of the bin is extremely dangerous as well as a difficult, if not impossible, method to obtain a representative sample. For this reason, this method of sampling is undesirable.
Discharge Sampling of Bins or Belts Bin samples can be taken at the discharge chute. In these cases a number. Determination of Crude Fibre 23 Maida, Fortified Maida, Protein Rich Maida 25 Semolina (Suji) 32 The test methods given in the manuals are validated/ standardized test methods.

The method compendium “Codex Standard ,” Recom-mended Methods of Analysis and Sampling, was updated in to include this method following the decision of CCMAS.

Properties of Textile Fibers and Their Testing Process Moisture content is expressed as a percentage of the total weight of the sample.
The standard test method ASTM D is most commonly employed in the textile industry to measure the regain and moisture content. The test is a simple one and can be easily performed.
A fiber sample. Zoning is a popular testing method of fiber that is used for selecting samples from raw cotton or wool or other loose fibre where the properties may vary considerably from place to place.
A handful of fibres is taken at random from each of at least 40 widely spaced places (zones) throughout the bulk of the consignment and is treated as follows.

ISOTextile fibres -- Some methods of sampling for testingAuthor: ISO TC 38/SC The method is applicable to most woven and nonwoven fabrics, knitted and stretch fabrics being an exception.
The test should be performed as directed in standards ASTM-D (strip method) and ASTM-D (grab method). Tearing strength test of fabric: There are three methods to test the tearing strength of a fabric.
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. Reichhold, Inc P.
