Work Item
ASTM WK94465
Revision of D7508/D7508M-20 Standard Specification for Polyolefin Chopped Strands for Use in Concrete
Rationale
1. A few of the definitions and terms within the specification do not coincide with some of our industry documents. The questionable terms will be reviewed to ensure congruency with other standards. 2. The minimum tensile strength for polyolefin macro fibers has remained unchanged for 15 years even though the polymer chemistry and process have significantly advanced. The minimum tensile strength will be revised to better suit industry expectations and today's practice.
