We work to the requirements of J-Std-001B and we use historical
     data and trend analysis to determine our testing frequency.
        We set up process control limits that are within the maximum
     contamination limits in table 5-1 of this spec.
        For us, Copper is generally the contaminant that will trigger
     replacement or replenishment
