Purpose.

The purpose of this standard is to verify the validity of data sent to the structural durability laboratory and ensure the data conform to the standards defined for the structural durability laboratories. This data is time history data from either physically measured Road Load Data Acquisitions (RLDA – see GMW15019) or analytical “virtual RLDA” (vRLDA). Occasionally, a Lab Load Data Acquisition (LLDA) measured on, for example, a full vehicle test, may be used as source data for a component or subsystem test. Standards described in this document: Standard Channel Measurement Conventions (Channel Nomenclature, Coordinate System, Positive Direction, Static Offsets), Data File Format and Data Quality Checks.
