you can now perform the post calibration the same way you did the pre calibration just record the flow rate on the pump calibration sheet the pre and post rates should be within 10 percent of each other if they are average the flow rates to determine the flow rate to be used to calculate the air volume all wrote on others are calibrated against a primary standard quarterly this calibration formula is located on the side of the road commenter the average Roe tomada reading and plug it into the calibration formula where the X's to determine your actual flow rate multiply the flow rate LPM by the total time sampled in minutes to get the air volume in leaders record the total leaders on the field pump datasheets and the chain of custody if the post sampling rate record the total leaders on the field pump datasheets and the chain of custody if the post sampling rates are not within 10 percent osha considers the samples screening samples and if the analytical results show high levels re sampling is recommended important be sure to pack TMP injure in the foam packing material for return shipment then complete the chain of custody for it is important that you include all the information requested in order to ensure the turnaround time with your samples remove the pink copy and keep this for your records send the white and yellow copies in with the samples to the lab in the large ziploc bag questions contact golson laboratories by phone email or I H live chat you may also access our extensive library of other helpful videos ed garsten labs dot com thank you
