The total length of the specimen should be sufficiently long at least 1. Record both the cross-head displacement and force, and strain if applicable. We need your help to maintenance this website. A fiber is extracted randomly from a bundle or from a spool. aatm

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

Advanced ceramic, glass, carbon and other fibers are covered by this test standard. No further reproductions authorized. Alternatively, the sides of the tab can be burned ast a soldering iron, for example. Have a question about conducting the test for this standard? 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.

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. An appropriate solvent can be used afterwards to remove the vacuum grease.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. By means of our testing expertise and modular product design, we will help find the solution that is right for you. 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. Radial and axial scales are not the same in these diagrams. Thank you for interesting in our services.

Size px x x x x 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.

All specimens are loaded to c15557, at a constant rate of cross-head displacement.

Last previous edition approved in as C — 03 For the purpose of determining the parameters of the distribution of fiber strengths it is recommended to follow this test method in astmm with Practice C Check the axial specimen alignment using whatever methods have been established, as described in 7.

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

Such non-gage section fractures constitute invalid tests. Give our test engineers a call today for help configuring the best test machine and accessories according to your standard.

Means for containing these fragments for later fractographic reconstruction and analysis is highly recommended. This test method constitutes a methodology to obtain the strength of a single fiber.

Sco Scope pe 1. We need your help! Precision and Bias We offer machines, awtm, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications. When using active gripping systems, insufficient pressure can lead to slippage, while too much pressure can cause local fracture in the gripping area. Handle the test specimen at its ends and avoid touching it in the test gage length.

The error bars correspond to the largest and smallest values of the errors resulting from repetitions.

Zero the load cell.
