ASTM G65 Abrasion Test Interpretation: A Ranking, Not a Wear-Life Promise

ASTM G65 Abrasion Test Interpretation: A Rankin...

ASTM G65 ranks metallic materials by their resistance to one kind of wear, scratching abrasion, under a specified laboratory procedure. The result is a volume loss, and a lower volume...

Rubber Rebound, Heat Build-Up and DMA: Which Dynamic Test Fits?

Rubber Rebound, Heat Build-Up and DMA: Which Dy...

Rebound, heat build-up and dynamic mechanical analysis (DMA) are not three scores for the same property. Rebound reports energy return after an impact. Heat-generation testing compares self-heating under repeated compressive...

Rubber Low-Temperature Brittleness Tests: What a Track’s Cold Rating Does Not Prove

Rubber Low-Temperature Brittleness Tests: What ...

A rubber brittleness temperature is a result for fracture under specified laboratory impact conditions—not an automatic minimum operating temperature for a rubber track. It also does not establish traction on...
