ASTM D3544-76(1996)

Standard Guide for Reporting Test Methods and Results on High Modulus Fibers (Withdrawn 2003)

SCOPE
1.1 Committee D-30, having conducted several interlaboratory tests of high modulus fibers, believes that many types of equipment and techniques will yield consistent data characterizing the tensile strength and modulus of high modulus fibers. The most important consideration is the complete description of the test methods.  
1.2 This guide consists of the following three parts:  
1.2.1 Part A- Description of Equipment and Techniques- This section describes the equipment and the techniques used for each series of tests. The section is complete and universal, and should be reviewed by the engineer or scientist responsible for the overall test program.  
1.2.2 Part B- Description of Test Specimens- This section describes each type of fiber tested in a particular series, and can be prepared by the test technician.  
1.2.3 Part C- Report of Tension Test Results- This section summarizes the results of each test series. The format simplifies the reporting of essential data. Additional information may be required to report the results of tests on specific fiber types.
1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
