ASTM D-2777 provides the standard practice for conducting an interlaboratory study to determine the precision and bias of a test method. However, no such practice exists for the initial development of a method to be used for compliance purposes. Method development cannot be prescriptive. This is a guide of suggested practices. Because methods vary widely in their chemistry and procedures, no definitive guidance can be provided on how to develop a rugged method. In general, though, the goal is a written document that demonstrates acceptable method performance is attained using all procedural options specified in the method.
