0 9 <br /> Results f Third Party Standard Evaluation <br /> Point i i Contact Product Detectors <br /> This form documents the performance of the cable sensor liquid contact leak detection system described below. <br /> 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 Mo3it9rin4, S std ems,,; Models ILS 350 (serial Neta 013) &TLS 25Q <br /> Version yjith Interstitial Li®uid Sensor for Fiberglass Ta390-401) <br /> Vendor Vtt er-Ro nviro ental Products <br /> 125 Powder Drive <br /> (street address) <br /> SMSLU CT Q6070-2003 (800) 873-3313 <br /> (city) (state) (zip) (phone) <br /> Detector output type: Qualitative <br /> Detector operating principle: _Electrical Conductivity Capacitance Change <br /> Interface Probe Product Permeable Product Soluble Thermal Conductivity <br /> Pressure Switch Magnetic Switch „Other (Float Switch) <br /> Detector sampling frequency: Intermittent Continuous <br /> Evaluation Results <br /> The detector described above was tested for its ability to detect test liquids in contact with the <br /> point sensor. 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 Camegie Mellon Research Institute.jest Procedures far Third Party Evaluation of Leak Wection Methods°Poirrt <br /> Sensor LiquidGontad Lea�Detection S std ems: Final Report-November 11, 1991. <br /> Liquid Contact Product Detector- Results Form Page i of 2 <br />
