Significance and Use
4.1 This practice provides a uniform procedure for fabricating glass fiber/thermoset resin ring samples for use as test specimens. Specimens so prepared can be used in Test Methods and .
1.1 This practice is intended for use in the fabrication of ring-type test specimens to be used in the evaluation of the mechanical properties of reinforcement and resins in a composite structure. The practice outlines the steps in the preparation of the test specimens, including the final specimen machining where applicable. Four final ring configurations are included.
1.2 The values stated in either SI units of inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
Note 1: There is no known ISO equivalent to this practice.
