What Is ASTM D6111 Plastic Lumber Bulk Density Specific Gravity?
ASTM D6110 describes a standard test method for determining the Charpy impact resistance of notched plastic specimens. The high-strain-rate test quantifies the energy absorbed by a material during fracture and directly measures toughness.
This test involves a notched specimen being struck by a pendulum hammer at controlled velocity. Measured energy absorption during fracture, in joules, indicates the material’s resistance to sudden impact forces. ASTM D6110 is widely used to evaluate the durability, resilience, and mechanical performance of plastic materials across industries.

ASTM D6111 Plastic Lumber Bulk Density Specific Gravity FAQs
This test measures plastic lumber's bulk density and specific gravity, through which performance and reliability will be assessed.
They directly affect how high strength-to-weight ratios translate to cost efficacy and application suitability.
The test requires a balance, immersion cage, immersion vessel, sinker, and wire setup.
Specimens are weighed in air and water, and the weights are used to calculate density and specific gravity.
The results aid in quality control, product acceptance/rejection, and optimizing the design and application of plastic lumber.
