Give our test engineers a call today for help configuring the best test machine and accessories according to your standard. Either analog chart recorders or digital data acquisition systems may be used for this purpose although a digital record is recommended for ease of later data analysis.
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.
ASTM C1557 – 14
The grips are designed so that axial alignment of the fiber along the line of action of the machine is accomplished without damaging the test specimen. All specimens are aatm to fracture, at a constant rate of cross-head displacement. Current edition approved Aug. Single fiber specimens are removed from fiber bundles or spools, should have a length at least 1.
However, other gage lengths can be used as long as they are practical, and in either case, the value of the gage length must be reported. A fiber is extracted randomly from a c157 or from a spool.

Means for asrm these fragments for later fractographic reconstruction and analysis is highly recommended. 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. Ideally, an analog chart recorder or plotter shall be used in conjunction with the digital data acquisition system to provide an immediate record of the test as a supplement to the digital record.
An appropriate solvent can be used afterwards to remove the vacuum grease. Materials Science Letters, 18, 24,pp.

We are a non-profit group that run this website to share documents. A number in paren parenthese thesess indicates the year of last reappr reapproval. Thank you for interesting in our axtm. We need your help! Handle the test specimen at its ends and avoid touching it in the test gage length.
Because of their nature, ceramic fibers do not have a unique strength, but rather, a distribution of strengths. Historical Version s – view previous versions of standard.
ASTM C – 14 – Standard Test Method for Tensile Strength and Young’s Modulus of Fibers
Have a question about conducting the test for this standard? Society, 83, 3, v1557, pp. 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.

Center the test specimen over the tab using the printed pattern with one satm taped to the tab. Radial and axial scales are not the same in these diagrams. This standard does not purport to address all of the safety concerns, if any, associated with its use. The total length of the specimen should be sufficiently long at least 1. Monte Carlo Simulation X1. We are confident that we have what you are looking for. Very short fibers including whiskers call for specialized test asmt 1 3 and are not covered by this test method.

Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more. Asttm, the sides v1557 the tab can be burned using a soldering iron, for example.
Such non-gage section fractures constitute invalid tests. Test specimens with at least three different gage lengths, and perform at least, three tests for each value of the gage length. This standard does not purport to address all of the safety concerns, if any, associated with its use.
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 Zero the load cell. The mounting 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. 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.
At the same time, the grip facing material must prevent crushing, scoring or other damage to the test specimen that would lead to inaccurate results.
