ASTM D6818-18a covers strip test procedures for determining the tensile properties of rolled erosion control products (RECPs).
The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
The strip test in this test method is considered satisfactory for acceptance testing of commercial shipments of rolled erosion control products, since the method has been used extensively in the trade for acceptance testing.
6.1 Tensile Testing Machine. of the constant rate of extel ion( CRE)type conforming to Specification D76/D76M, with respect to force indication, working range, capacity, and elongation indicator and designed for operation at a speed of300±10mm/min(i2±0.5in./min).
2 Clamps and Jaw Faces-Each jaw face shall be smooth,
and with a metallic or other agreed-upon surface.
faces shall be parallel and have machining centers with respect to one another in the same clamp and to the corresponding jaw face of the other clamp. The jaw faces shall measure at least 0 mm (0.5 in )wider than the specimen being tested and at least 25 mm(1.0 in. ) in height.
7. 1 Lot Sample-In the absence of other guidelines, divide the product into lots and take lot samples in accordance with Practice D4354.
