Give our test engineers a call today for help configuring the best test machine and accessories according to your astk. Originally approved in Referenc Referenced ed Documents Documents 4. 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.

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. We are a non-profit group that run this website to share documents.

C1557.31478

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. No other units of measurement are included in this standard. 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. 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 Radial and axial scales are not the same in these diagrams.

Force range of 5 kN to kN 1, lbf toastmm 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.

ASTM C – 03e1 Standard Test Method for Tensile Strength and Youngs Modulus of Fibers

The total length of the specimen should be sufficiently long at least 1. Means for containing these fragments for later fractographic reconstruction and analysis is highly recommended.

Such non-gage section fractures constitute invalid tests. We need your help!

Very short fibers including whiskers call for specialized test techniques 1 3 and are not covered by this test method. Center the test specimen over the tab using the printed pattern with one end taped to the tab.

When using active gripping systems, insufficient pressure can lead to slippage, while too much pressure can cause local fracture in the gripping area. Society, 83, 3,pp.

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. Link to Active This link will always route to the current Active version of the standard.

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.

ASTM C – 14 – Standard Test Method for Tensile Strength and Young’s Modulus of Fibers

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.

Please help us to share our service with your friends. Current edition approved Aug. Handle the test specimen at its ends and avoid touching it in the test gage length. No other units of measurement are included in this standard.

ASTM C1557 Tensile Fibers Test Equipment

Because of their nature, ceramic fibers do not have a unique strength, but rather, a distribution of strengths. Summ Summary ary of Test Test Method This sta stand ndar ard d ashm inv involv olvee haz hazar ardo dous us mat materia erials, ls, 1. Monte Carlo Simulation X1.

Have a question about conducting the test for this standard? 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. Test specimens with at least three different gage lengths, and perform asgm least, three tests for each value of the gage length.

A fiber is extracted randomly from a bundle or from a spool. Asttm, the sides of the tab can be burned using a soldering iron, for example. 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 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.
