EN 16657:2016+A1:2018 (E) 5 1 Scope This European Standard specifies the minimum performance and construction requirements for overfill prevention controllers located on the tank vehicle. This European Standard applies to overfill prevention controllers for liquid fuels, having a flash point up to but not exceeding 100 °C. The requirements apply to overfill prevention controllers suitable for use at ambient temperatures in the range from -25 °C to +60 °C, and subject to normal operational pressure variations. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 13616-2:2016, Overfill prevention devices for static tanks for liquid fuels — Part 2: Overfill prevention devices without a closure device EN 14116, Tanks for transport of dangerous goods — Digital interface for the product recognition devices for liquid fuels EN 60079-0, Explosive atmospheres — Part 0: Equipment — General requirements (IEC 60079-0, modified) EN 60079-11, Explosive atmospheres — Part 11: Equipment protection by intrinsic safety “i” (IEC 60079-11) EN 61000-6-1, Electromagnetic compatibility (EMC) — Part 6-1: Generic standards — Immunity for residential, commercial and light-industrial environments (IEC 61000-6-1) EN 61000-6-3, Electromagnetic compatibility (EMC) — Part 6-3: Generic standards — Emission standard for residential, commercial and light-industrial environments (IEC 61000-6-3) EN ISO 13849-1, Safety of machinery — Safety-related parts of control systems — Part 1: General principles for design (ISO 13849-1) ISO 7637-2, Road vehicles — Electrical disturbances from conduction and coupling — Part 2: Electrical transient conduction along supply lines only 3 Terms, definitions and abbreviated terms For the purposes of this document, the terms, definitions and abbreviated terms given in EN 13616-2 and the following apply. 3.1 Terms and definitions 3.1.1 overfill prevention controller controller installed on the tank vehicle, connects to sensors mounted in or on the tank, and provides an output SIST EN 16657:2016+A1:2018



EN 16657:2016+A1:2018 (E) 6 3.2 Abbreviated terms PRD Product Recognition Device 4 Requirements 4.1 Effectiveness The filling process shall not start or shall automatically stop in the event of failure of the power supply. Detection of a sensor´s signal "non-permissive" shall result in a shut-down of the product flow by the controller. Stopping the product flow shall not generate pressure in excess of the designed criteria for the whole system. 4.2 Construction The design shall be compatible with the ambient temperature range of -25 °C to +60 °C. The manufacturer shall confirm the compatibility of materials, which may be in contact with the liquid and/or its vapour phase. If the controller forms part of an earth continuity path, then the conductivity of the path shall be < 106
The controller shall be of a durable construction. The selection of materials and manufacturing processes shall consider environmental aspects. 5 Overfill prevention device 5.1 Equipment on the tank A sensor with mechanical interface shall be according to EN 13616-2.
