I have been running C1260's on some aggregates known to be innocuous and have been getting results higher than typically seen for this aggregate. We are using 20% ash mitigation, but still high. I have done some round-robin testing with other labs and found that results are all over the map (we are about in the middle). i think i have narrowed it down to the containers i am using during the test. I weighed the container and solution before and after the test and found i was losing some weight. i believe i have some evaporation going on thereby strengthening the solution concentration. We are using rubbermaid 5.6L contaners. Does anyone have a suggestion / source for better containers? Any other suggestions?
