Geomembranes play a critical role in modern containment systems, from landfills and wastewater lagoons to mining operations and industrial ponds. Because these liners are designed to prevent leaks ...

ASTM D6204 Parts A, B and C (RPA Frequency Sweeps and VTA Curing); ASTM D6601 (RPA Strain Sweeps of in situ Cured Dynamic Properties); and ASTM D8059 (RPA Strain Sweep using the Payne Effect Method ...

In my July 2005 column, a new ASTM standard shear test method was introduced 1. At that time, I raised the question, Why do we need another shear test method for composite materials?, with the promise ...

When first introduced to mechanical testing of composite materials, one can be confused, even overwhelmed, by the number of available test standards. One reason for this large variety of tests is the ...

Over the last three decades, the rubber process analyzer has evolved as the processability test instrument of choice for measuring and solving many rubber factory problems. Also, a new ASTM reflective ...

ASTM test methods are petroleum industry standards, accepted worldwide for quality and reliability. ASTM test methods for petroleum and refined products include: Petroleum and Petrochemical Test ...

The 90-year-old technology of using rubber gloves for shock and leather gloves for protection of the rubber soon could be turned on its head by innovation. For years, we have heard the question, "What ...

For years, we have heard the question, "What about gloves in arc flash?" The reason this question wasn't answered sooner is complicated, but the standard is now available. ASTM F2675-13, Test Method ...

The offset shear strength is the shear stress endured by a material at the intersection of the shear stress versus the engineering shear strain curve, with a line parallel to a defined modulus and ...

So that it may be certain that a concrete specimen’s mechanical properties reach the strength and deflection imperatives for its intended use, concrete specimens with specific dimensions are prepared, ...
