ASTM E2493-07

Standard Guide for the Collection of Non-Volatile Memory Data in Evidentiary Vehicle Electronic Control Units (Withdrawn 2016)

SIGNIFICANCE AND USE
This guide sets forth recommendations for the collection of non-volatile memory data from a vehicle ECU or EDR that, to the extent possible, do not alter the data being collected.
This guide sets forth recommendations for the collection of non-volatile memory data from a vehicle ECU or EDR that, in the case where data may be altered during the collection process, informs the parties involved of the risk and type of alteration that may occur.
SCOPE
1.1 This guide sets forth recommendations for the collection of non-volatile memory data from vehicle Electronic Control Units (ECUs), or Event Data Recorders (EDRs), that have allegedly been involved in an event or incident that is the subject of litigation.
1.2 The data collection methods used to retrieve data from the subject ECU or EDR include commercially available scan/interrogation/test tools and also include proprietary scan/interrogation/test tools with prior agreement of the parties involved.
1.3 Additional, and potentially applicable, standards promulgated by ASTM Committee E-30 on Forensic Sciences include: Practices E 860 and E 1188.
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 and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
This guide sets forth recommendations for the collection of non-volatile memory data from vehicle Electronic Control Units (ECUs), or Event Data Recorders (EDRs), that have allegedly been involved in an event or incident that is the subject of litigation.
Formerly under the jurisdiction of Committee E58 on Forensic Engineering, this guide was withdrawn in January 2016 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
