Handle the test specimen at its ends and x1557 touching it in the test gage length. Thank you for interesting in our services. The total length of the specimen should be sufficiently long at least 1.

Because of their nature, ceramic fibers do not have a unique strength, but rather, c15557 distribution of strengths.

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. Such non-gage section fractures constitute invalid tests. Record both the cross-head displacement and force, and strain if applicable.

C5157 the same time, the grip facing material must prevent crushing, scoring or other damage to the test specimen that would lead to inaccurate results. Radial and axial scales are not the same in these diagrams. Check the axial specimen alignment using whatever methods have been established, as described in 7. We need your help to maintenance this website.

The error bars correspond to the largest and smallest values of the errors resulting from repetitions. Society, 83, 3,pp. 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. Have a question about conducting the test for this standard?


A number in paren parenthese thesess indicates the year of last reappr reapproval. When using active gripping systems, insufficient pressure can lead to slippage, while too much pressure can cause local fracture in the gripping area. Sco Scope pe 1.

This test method constitutes a methodology to obtain the strength of a single fiber. Alternatively, the sides of the tab can be burned using a soldering iron, for example. The system compliance is determined as follows: This standard does not purport to address all of the safety concerns, if any, associated with its use. Zero the load cell. No other x1557 of measurement aetm included in this standard.

We are confident that we have what you are looking for.

By means of our testing expertise and modular product design, we will help find qstm solution that is right for you. However, other gage lengths can be used as long as they are practical, and in either case, the value of the gage length must aatm reported.

ASTM C1557 – 14

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. 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 Very short fibers including whiskers call for specialized test techniques 1 3 and are not covered by this test method.

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.
