e <br /> C-3 <br /> Results of Third Party Standard Evaluation <br /> Point Sensor Liquid Cflntact Product Detectors <br /> This form documents the performance of the cable sensor liquid contact leak detection system described below. <br /> I The evaluation was conducted by the equipment manufacturer or a consultant to the manufacturer according to the <br /> Third Party Procedures developed according to the U.S. EPA's "Standard Test Procedure for Evaluating Leak <br /> Detection Methods: Liquid-Phase Out-of-Tank Product Detectors"1 <br /> Tank owners using this leak detection system should keep this form on file to prove compliance with the federal <br /> regulations. Tank owners should check with state and local agencies to verify that this form satisfies their <br /> requirements. <br /> Method Description - <br /> Name 350 Series UST Monitorin95Ystems• Models ILS 35Q.(serial #Beta Q12) !a TIS 35n <br /> Version with Interstitial Liquid Sensor for Steel Tanks (0794390-4 0) <br /> Vendor Veeder-Ro a nvimnmental Products <br /> 125 Powder Forrest Drive <br /> (street address) <br /> Simsburv.

The following parameters were determined: <br /> • Detection Accuracy - The measure of sensor response to the presence of liquids. <br /> • Response Time - Amount of time the detector must be exposed to liquid before it responds. <br /> • Recovery Time - Amount of time that passes before the detector returns to its baseline reading <br /> after the test liquid is removed. <br /> • Lower Detection Limit - The smallest liquid concentration that the detector can reliably detect. <br /> • Product Activation Height - The height of liquid to cause sensor activation. <br /> • Specificity - Indicates the level of response, of the detector, to several different liquids. <br /> 1 Carnegie Mellon Research Institute.Test Procedures for Third Party Evaluation of Leak De1ection Methods, Point <br /> Sensor I iouid Contact Leak Qetection Systems: Final Report- November 11, 1991. <br /> Liquid Contact Product Detector-Results Form Page 1 of 2 <br />
