Revision of D5406-93(2016) Standard Practice for Rubber—Calculation of Producer's Process Performance Indexes


Three changes are proposed: 1) replace the one occurrence of "assignable causes", which is not defined, to "special causes", which is defined; 2) remove duplication of the second half of the sentence in paragraph 7.7; and 3) add a paragraph to explain calculations and reporting when using a customer's specification limits instead of the producer's specification limits in the calculations and reporting.
