14、echnical Report (CEN/TR 14489:2005) has been prepared by Technical Committee CEN/TC 19 “Petroleum products, lubricants and related products”, the secretariat of which is held by NEN. This document has been prepared under mandate M/238 given to CEN by the European Commission and the European Free Tra

15、de Association along with other standards on fire-resistant hydraulic fluids to be complementary to the regulatory measures contained in various EU Directives. The mandated work of CEN/TC 19 is to develop European Standards for specifications and testing conditions applicable to fire-resistant hydra

16、ulic fluids. 4 Introduction The function of this Technical Report is to provide suppliers and users of equipment guidance on how compliance with the essential health and safety requirements (EHSRs) incorporated in both Product (Article 95) and User (Article 137/138) Directives issued by the European

17、 Union may be achieved in respect of the use of fire-resistant hydraulic fluids. It builds upon the guidance provided in EN 1050 on the principles of risk assessment. EN 1050 in turn supports Directive 92/104/EEC 1. The document was considered necessary because the specialised nature of fire-resista

18、nt fluids and the tests used to quantify their properties may not in general be familiar to prospective machinery manufacturers and users. Because several Directives deal with the prevention of fire it is necessary to consider other aspects in addition to the tests used to quantify fire properties.

19、The use of fire-resistant hydraulic fluids is a fire protection measure. A fire occurs if combustible materials or explosive gases, oxygen and an ignition source are all present at the same time. If there is a danger of an ignition source being present when hydraulic installations are in use, one me

20、thod of improving safety may be to replace more combustible mineral oil by a fire-resistant hydraulic fluid. Fire-resistant fluids provide fire protection. Their use, however, shall not jeopardise other safety measures as, in addition to requirements for fire resistance, there are additionally requi

21、rements for assessing effects on the health of workers and, increasingly, on potential effects on the environment. Guidance on the information needed is contained in this Technical Report. IMPORTANT This document does not purport to address all of the safety problems associated with the use of hydra

22、ulic systems. It is concerned with the use of fire-resistant fluids as a means of reducing the risk of fire. It is the responsibility of the user of this document to establish appropriate safety and health practices to reduce other safety risks and to determine the applicability of regulatory regime

23、s. CEN/TR 14489:20055 1 Scope This Technical Report gives guidance on the achievement of compliance with Essential Health and Safety Requirements (EHSR) by the selection of fire-resistant fluids or by other means. It includes consideration of the selection of fluids with lower levels of fire resista

24、nce and of mineral oil, with appropriate additional safety measures, where this option may be considered to be most satisfactory during operation. This Technical Report is concerned with assessing the fire resistance, health properties and effects on the environment, but does not cover requirements

34、ng. Where fire-resistant fluids are chosen they shall make an overall contribution towards improving safety. Hence they shall not only meet requirements for fire resistance but also for the protection of the health of workers and the environment and, shall not jeopardise other safety measures that m

35、ay be in use. The primary reason for selecting fire- resistant fluids is to protect against the risk of fire: protection of the environment may be achieved by methods other than the properties of the fluids. CEN/TR 14489:20057 In some countries in the European Union (EU) and European Free Trade Asso

36、ciation (EFTA) governments operate approval schemes for hydraulic fluids or impose local regulations, which require that particular levels of performance be met in specific tests to allow fluids to be used in certain industrial situations (see Annex A). Compliance with these schemes and regulations

37、is considered by the regulatory authorities in those countries to constitute compliance with the appropriate EU Directives for the application of hydraulic fluids. It should be noted that such regulations take precedence over CEN standards, and potential suppliers and users of hydraulic fluids shoul

38、d establish whether approval schemes or local regulations exist. Annex A contains a list of the countries that operate approval schemes for hydraulic fluids or impose local regulations. Fire-resistant hydraulic fluids shall conform to the specifications laid down for the various industries by the Eu

39、ropean Authorities and/or the certification authorities of each member state according to the risks arising in each industry, distinguishing if necessary between installations giving rise to greater or lesser hazards. Certification shall be carried out with reference to the specifications and standa

40、rds issued by the European or national authorities and should be based on the tests contained in Annex B and C of this Technical Report. 5 Classification of fire-resistant fluids Table 1 lists the main categories of fire-resistant fluids as found in EN ISO 6743-4, their compositions and applications

41、. Fire-resistant fluids in accordance with EN ISO 6743-4 are hydraulic fluids which are classified as fire-resistant in accordance with particular fire test procedures. They achieve their fire resistance either because they contain water or because their chemical composition confers fire resistance.

42、 Only water and fire-resistant fluids of type HFA with water content above 90 % are considered to be non-combustible. Fire-resistant fluids do, however, require a substantially greater input of energy to cause ignition than conventional mineral oil hydraulic fluids and may not sustain combustion aft

43、er leaving the ignition source. The level of fire resistance shall be established by the use of a range of standard protocols (for guidance see Annex B). In the event that a test representing the particular circumstance of use is not included in EN ISO 12922 then data from other fire-resistance test

44、s having adequate precision may be invoked, subject to local regulations.
