26、 by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This document is Part 3 of a European Standard specifying the safe
27、ty requirements for hydraulic control systems. The other parts are: Part 1: Support units and general requirements Part 2: Power set legs and rams Part 41: Electro-hydraulic control systems According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following count

The machinery concerned and the extent to which hazards, hazardous situations and events are covered
30、are indicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards for machines that have been designed and built ac
31、cording to the provisions of this type C standard. The extent to which hazards are covered is indicated in the scope of this document. While preparing this document, it was assumed that: only trained and competent persons operate the machine; components without specific requirements are; a) designed
32、 in accordance with the usual engineering practice and calculation code; b) of sound mechanical construction; c) free of defects; components are kept in good working order; a negotiation took place between the user and the manufacturer concerning the use of the machinery.

33、 1804-3:2006+A1:2010 (E) 6 1 Scope This document specifies the safety requirements for hydraulic control devices, including hydraulic valves and their control elements, valve combinations, control systems, pipes and hose assemblies, fittings, shut-off devices, measuring devices, filters, built-in pr
34、essure limiting and check valves in legs and rams and water spraying and dust suppression valves when used as specified by the manufacturer or his authorized representative. Excluded are electronic control devices, pressure generators, and internal valves of legs and rams (e.g. constant yield valves
35、, see EN1804-2). Some components are dealt with in other parts of this standard. NOTE prEN1804-4 also applies to electro-hydraulic control devices. Part 4 also contains requirements for electrical control elements of valves. This document applies to hydraulic control devices at ambient temperatures
36、from 10 C to 60 C. This document identifies and takes into account: possible hazards which may be caused by the operation of hydraulic control devices; areas and operating conditions which may create such hazards; hazardous situations which may cause injury or may be damaging to health; hazards whic
37、h may be caused by firedamp and/or combustible dusts. This document describes methods for the reduction of these hazards. A list of significant hazards covered appears in clause 4. This document is applicable to all hydraulic control devices placed on the market for the first time after the date of
38、issue of this standard. This document does not specify any additional requirements for: use in particularly corrosive environments; hazards occurring during construction, transportation, decommissioning; earthquakes. 2 Normative references The following referenced documents are indispensable for the
