EN 1648, Leisure accommodation vehicles - 12 V direct current extra low voltage electrical installations contains the following parts:  Part 1: Caravans (the present document);  Part 2: Motor caravans. This document is based on ISO 8818 “Leisure accommodation vehicles — Caravans — 12 V direct current extra low voltage electrical installations” and takes into consideration specific aspects relating to electrical installations in caravans. The requirements of relative ISO/IEC and CENELEC publications were taken into consideration during the preparation of this European Standard. This document is one of a series covering the habitation aspects of leisure accommodation vehicles. SIST EN 1648-1:2012

5 Requirements for 12 V direct current extra low voltage electrical installations for motor caravans are specified in EN 1648-2. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

7 1 Scope This European Standard specifies safety, health and functional requirements for 12 V direct current (DC) extra low voltage (ELV) electrical installations for habitation aspects of caravans. It covers the design and integration of the caravan system with the towing vehicle system. It does not apply to commercial trailers; nor does it include requirements for ELV road lighting and signalling lamps and their installations, except for safety requirements for the routing of cables in LPG storage compartments. This European Standard also specifies the ELV output requirements of low voltage (LV) equipment that may be used to provide an ELV supply but it does not specify safety, technical and functional requirements for LV appliances and installations. Requirements for LV installations are specified in HD 60364-7-721. 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.
