Link to Active This link will always route to the current Active version of the standard. The c157 tabs are gripped or connected to the load train for example, by pin and clevis so that the test specimen is aligned axially along the line of action of the test machine.
All specimens are loaded to fracture, at a constant rate of cross-head displacement. Test specimens with at least three different gage lengths, and c157 at least, three tests for each value of the gage length.
Current edition approved Aug. Last previous edition approved in as C — 03 Please copy and paste this embed script to where you want to embed Embed Script. Record both the cross-head displacement and force, and strain if applicable.
ASTM C – 03e1 Standard Test Method for Tensile Strength and Youngs Modulus of Fibers
At the same time, the grip facing material must prevent crushing, scoring or other damage to the test specimen that asstm lead to inaccurate results. Society, 83, 3,pp. Means for containing these fragments for later fractographic reconstruction and analysis is highly recommended.
However, other gage lengths can be used as long as they are practical, and in either case, the value of the wstm length must be reported. Ideally, an analog chart recorder or plotter shall be used in conjunction with the digital data acquisition system to provide an asgm record of the test as a supplement to the digital record.
Materials Science Letters, 18, 24,pp. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
No further reproductions authorized. Because of their nature, ceramic fibers do not have a unique strength, but rather, a distribution of strengths. The error bars correspond to the largest and smallest values of the errors resulting from repetitions.
For the purpose of determining the parameters of the distribution of fiber strengths it is recommended to follow this test method in conjunction with Practice C Center the test specimen over the tab using the printed pattern with one end taped to the tab. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Radial and axial scales are not the same in these diagrams. We need your help to maintenance this website. Sco Scope pe 1. Check asmt axial specimen alignment using whatever methods have been established, as described in 7.
Referenc Referenced ed Documents Documents 4. This standard does not purport to address all of the safety concerns, if any, associated with its use. The grips are designed so that axial alignment of the fiber along the line of action of the machine is accomplished without sstm the test specimen.
Handle the test specimen at its ends and avoid touching it in the test gage length.
ASTM C is the standard test method for determining the tensile strength and elastic Young’s modulus of single ceramic, glass, carbon and other fibers at ambient temperature. No other units of measurement are included in this standard.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
In most cases when the strength of the fibers is controlled by one population of flaws, the distribution of fiber strengths can be described using a two-parameter Weibull distribution, although other distributions have also been suggested 23.
The fiber is mounted in the testing machine, and then stressed to failure at a constant cross-head displacement rate. Single fiber specimens are removed from fiber bundles or spools, should have a length at least 1.
Very short fibers including whiskers call for specialized test techniques 1 3 and are not covered by this test method. When using active gripping systems, insufficient pressure can lead to slippage, while too much pressure can cause local fracture in the gripping area.
Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models. Have a question about conducting the test for this standard? The total length of the specimen should be sufficiently long at least 1. The system compliance is determined as follows: A fiber is extracted randomly from a bundle or from a spool.
This test method may also be useful in the initial screening of candidate fibers for applications in polymer, metal or ceramic matrix composites, and quality control purposes. By means of our testing expertise and modular product design, we will help find the solution that is right for you.
