Current edition approved June 1, 2015. Published August 2015. Originally approved in 1975. Last previous edition approved in 2009 as F414 – 09. — 4 p.
This test method covers the determination of tire plunger energy required to completely penetrate the tread area of an inflated tire as indicated by a rupture, loss of inflation pressure, sudden drop in plunger force or bottom-out. The test requires utilization of a laboratory testing machine capable of slowly penetrating the tread surface of a tire with a plunger having a hemispherical end.
This test method is applicable to pneumatic tires for vehicles normally used on the road.
