ASTM F 1805 - 16 Standard Test Method for Single Wheel Driving Traction in a Straight Line on Snowand Ice-Covered Surfaces

Current edition approved Jan. 1, 2016. Published February 2016. Originally approved in 1997. Last previous edition approved in 2012 as F1805 – 12. — 14 p.
This test method covers a procedure for measuring the driving traction of passenger car and light truck tires while traveling in a straight line on snow- or ice-covered surfaces.
This test method utilizes a dedicated, instrumented, four-wheel rear-wheel drive test vehicle with a specially instrumented drive axle to measure fore-aft and vertical forces acting on a single driven test tire.
This test method is suitable for research and development purposes where tires are compared during a single series of tests. They may not be suitable for regulatory statutes or specification acceptance because the values obtained may not necessarily agree or correlate either in rank order or absolute traction performance level with those obtained under other environmental conditions on other surfaces or the same surface after additional use.
