ICS 53.060 BS EN 1525:1998 National foreword This British Standard is the English language version of EN 1525:1997, published by the European Committee for Standardization (CEN) The UK participation in its preparation was entrusted to Technical Committee MHE/7, Industrial trucks, which has the responsibility to: — aid enquirers to understand the text; — present to the responsible European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; — monitor related international and European developments and promulgate them in the UK A list of organizations represented on this committee can be obtained on request to its secretary Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application Compliance with a British Standard does not of itself confer immunity from legal obligations Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, the EN title page, pages to 14, an inside back cover and a

comprises the control system, which may be part of the truck and/or separate from it, the guidance means and the battery charging system 1.4 This European Standard deals with the technical requirements to minimize the hazards listed in clause which can arise during the commissioning, operation and maintenance of trucks in accordance with the specifications given by the manufacturer or his authorized representative In addition, trucks should comply as appropriate with EN 292 for hazards not covered by this standard or the applicable companion standards 1.5 This European Standard covers specific hazards related to the automated functions of trucks and their systems listed in clause This standard must be used in conjunction with one or more of the applicable companion standards listed in the foreword 1.6 The provision of a portable control unit does not classify the truck as a pedestrian controlled truck 1.7 The environment of trucks can have a significant effect on their safe operation Annex A establishes requirements for the preparation of the environment to eliminate the associated hazards For the person responsible for the integration of the trucks into the workplace, Annex A is normative 1.8 This European Standard does not establish the following additional requirements for: a) operation in severe conditions (e.g extreme climates, freezer applications, strong magnetic fields); b) operation in environments subject to special rules (e.g potentially explosive atmospheres); c) electromagnetic compatibility; d) transportation of passengers; e) handling of loads the nature of which could lead to dangerous situations (e.g molten metals, acids/bases, radiating materials); f) parts of trucks requiring manual intervention during operation Normative
