Research Report RR:B09-1011
An interlaboratory study was performed by nine laboratories testing two tungsten carbide powders in the laboratory-milled condition to establish a precision statement for test method B761. This report has been published in the absence of any other precision estimates for B761, despite not testing enough materials to provide statistically valid results as per ASTM Standard Practice E691.
