Research Report RR:D02-1878

    This interlaboratory study was conducted to Establish Precision Statements for D7420, Test Method for Determining Tribomechanical Properties of Grease Lubricated Plastic Socket Suspension Joints Using a High-Frequency, Linear-Oscillation (SRV) Test Machine. It was elaborated in cooperation with the DIN 51834 working group. The DIN 51834 has incorporated based on round robin tests performed in 2003, 2004 and 2006 modifications onto this TRW-procedure and add the precision statements.
