(Test Method)Standard Test Method for Accelerated Laboratory Roadwheel Generation of Belt Separation in Radial Passenger Car and Light Truck Tires through Load Range E
Standard Test Method for Accelerated Laboratory Roadwheel Generation of Belt Separation in Radial Passenger Car and Light Truck Tires through Load Range E
SIGNIFICANCE AND USE
4.1 Belt edge separation is a tire condition that can be encountered in tire use, particularly in high tire temperature environments.
4.2 The goal of this standard is to define a scientifically valid protocol for the laboratory generation of belt edge separation in a tire that has previously completed accelerated laboratory aging as described in Practice F2838. This test method does not establish performance limits or tolerances for tire specifications.
4.3 However, as stated in the scope, some tires may not develop belt edge separations under the specified test conditions. They may develop other EOT conditions that are not due to belt edge separation. Also, some tires may not develop any EOT conditions during the course of the test prior to a DCT.
SCOPE
1.1 This standard describes a laboratory method to evaluate tires for their tendency to develop belt edge separation, via the use of a standard roadwheel (Practice F551/F551M). This evaluation is conducted on tires that have undergone accelerated laboratory aging as described in Practice F2838.
1.2 The End-of-Test (EOT) conditions that can be produced by this method include target (belt-edge separation), non-target (conditions other than belt-related separations that can be developed in passenger and light truck tires through on-road use), and non-representative (conditions that are typically developed only on laboratory roadwheels). There is also the possibility that no visible EOT conditions may be generated during the course of this test. In this instance the user may choose to select a designated completion time (DCT) as the EOT condition.
1.3 The values stated in SI units are to be regarded as the standard. The values given in the data log in Appendix X1 in parentheses are provided for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 6.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

INTRODUCTION
The United States Congress passed the Transportation Recall Enhancement, Accountability and
Documentation (TREAD) Act in November 2000. Included in the Act were specific directions to the
National Highway Traffic Safety Administration (NHTSA) to upgrade tire safety standards.
As tire wear life has increased over the years, interest in the in-service aging of a tire’s internal
components has increased. To quote NHTSA, “. some members of Congress expressed the view that
