The Global Revolution in Mobility
The world around us is changing and it’s evolving at an increasingly rapid pace. Unprecedented advancements in technology, regulations and society, coupled by the impact of a global pandemic, are transforming the way citizens around the world work, move and interact. Join Brian Goldstine, president of mobility solutions and fleet management at Bridgestone Americas, as he dissects what these trends mean for the future of the tire industry as consumers, fleets and OEMs challenge tire manufacturers and servicing dealers to deliver integrated tire solutions that improve safety, efficiency, sustainability and profitability.

ASTM International: Introduction
The presentation will cover the role of ASTM International, as one of the largest voluntary standards developing organizations in the world. ASTM is a not-for-profit organization that provides industry experts a balanced forum to improve the safety, quality, and efficiency within their industry. ASTM’s volunteer members represent producers, users, consumers, government, and academia from more than 140 countries, who develop technical documents that are the basis of manufacturing, management, procurement, codes and regulations. ASTM volunteer members belong to one or more standards-writing committees, each of which covers a subject area such as D11 on Rubber and Rubber-like Materials.
SPEAKERS: Melissa Marcinowski, D11 Manager, Technical Committee Operations Division, ASTM International; David Lee, ASTM F09 Staff Manager, ASTM International
F421 - Standard Test Method for Measuring Groove and Void Depth in Passenger Car Tires and F1016 - Standard Practice for Linear Tire Treadwear Data Analysis
“An overview of two related passenger car tire ASTM standards: F421 - Standard Test Method for Measuring Groove and Void Depth in Passenger Car Tires and F1016 - Standard Practice for Linear Tire Treadwear Data Analysis.” This presentation provides an overview of two ASTM standards relating to passenger car tire treadwear measurement and linear treadwear data analysis. The first, Standard F421 offers guidance on the procedures to actually measure groove and void depths to determine the rate of wear of the tire. This standard addresses both rib type tires, having circumferential grooves as well as lug type tires. Suggested results include average groove (or void) depth for each circumferential group of measurements as well as the average tread depth, which is the arithmetic mean of all measurements. This standard also provides guidance and cautions on the measuring gauge and spindle configuration used to measure the depth. This standard only addresses mechanical or electromechanical gauges with a physical contacting spindle. Non-contact methodology, although commercially available, is beyond the scope of this standard. The second ASTM standard, F1016, offers guidance to use the data collected via F421 (based on known distance travelled) to perform elementary linear regression with the goal of establishing a projected treadlife. This standard emphasizes a consistent use of terminology based on results from commonly available regression software, instead of the actual regression (least squares) calculations.
