11、language version of EN 589:1993 Automotive fuels LPG Requirements and methods of test, published by the European Committee for Standardization (CEN). EN 589:1993 was produced as a result of international discussions in which the United Kingdom participated. BS EN 589 supersedes BS 4250-2:1987, which
12、 is withdrawn. EN 589 requires that each country implementing it establishes national annexes detailing requirements for sampling, pump marking and winter grades. These requirements are detailed in National annex NA, National annex NB and National annex NC, respectively. The principal differences be
13、tween this British Standard and BS 4250-2:1987 are as follows: a) requirements for composition are no longer included; b) requirements for pump marking have been introduced; c) the minimum motor octane number requirement has been reduced from 90 to 89; d) no requirements are now included for levels
14、of mercaptan sulfur, ethylene and C5 and higher hydrocarbons; e) requirements for gauge vapour pressure are no longer included but vapour pressure is now specified for winter grade fuels; f) comprehensive cautionary statements on health and safety considerations when undertaking odour testing are no
15、w included. CAUTION. Attention is drawn to the cautionary statement in 6.2. Attention is also drawn to the guidance notes associated with the Control of Substances Hazardous to Health Regulations 1988, such as the current version of Guidance Note EH 40 Occupational exposure limits, published by the
16、Health and Safety Executive (available from Her Majestys Stationery Office). 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 conf
17、er immunity from legal obligations.

The Standard was approved and in accordance with the CEN/CENELEC Internal Regulations,
25、 the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom. This European Standard shall be given the status of
26、a national standard, either by publication of an identical text or by endorsement, at the latest by September 1993, and conflicting national standards shall be withdrawn at the latest by September 1993. This European Standard has been prepared under a Mandate given to CEN by the Commission of the Eu
27、ropean Communities and the European Free Trade Association. Annex A and Annex B are normative and form an integral part of this European Standard.

28、 Standard specifies requirements and methods of test for automotive LPG (liquefied petroleum gases) as marketed and as delivered in the countries of the members of CEN. It is applicable to automotive LPG for use in vehicles fit to run on automotive LPG. DANGER. Attention is drawn to the risk of fire
29、 and explosion when handling LPG and to the hazard to health which arises through inhalation of excessive amounts of LPG. LPG is a highly volatile hydrocarbon liquid which is normally stored under pressure. If the pressure is released large volumes of gas will be produced which form flammable mixtur
30、es with air over the range 2 % V/V to 10 % V/V. This European Standard involves the sampling, handling and testing of LPG. All procedures should be conducted away from sources of ignition such as naked flames, unprotected electrical equipment and electrostatic hazards. Testing should be performed as
31、 far as practicable under an electrically-safe ventilation hood. LPG in the liquid form can cause cold burns to the skin. Protective clothing such as gloves and goggles should be worn if contact with the skin is likely to occur. Unnecessary inhalation of LPG vapour should be avoided. The operator sh
32、ould not be exposed to atmospheres containing more than 1 800 mg/m3 over an 8 h time-weighted average (TWA) reference period, or greater than 2 250 mg/m3 over a short term, 10 min reference period. One of the tests described in this European Standard involves the operator inhaling a mixture of air a
33、nd LPG vapour. Particular attention is drawn to the cautionary statement provided in 6.2, where this method is referred to. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the approp
34、riate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

These consist pre
39、dominantly of propane, butanes, with small proportions of propene, butenes and pentanes/pentenes 4 Sampling Samples shall be taken as described in ISO 4257 and/or in accordance with the requirements of national standards or regulations for the sampling of automotive LPG. The national requirements sh
40、all be set out in detail or shall be referred to by reference in a national annex to this European Standard. NOTEIt is important that the sampling procedure is followed in detail in order to avoid evaporation losses. 1) To be published. (CEN implementation of ISO 4260:1987, to replace EN 41:1975, De

42、pumps used for delivering automotive LPG, and the dimensions of the mark shall be in accordance with the requirements of national standards or regulations for the marking of pumps for automotive LPG. Such requirements shall be set out in detail or shall be referred to by reference in a National anne
43、x to this European Standard. 6 Requirements and test methods 6.1 Water Liquefied petroleum gases for automotive purposes shall not contain free water or suspended water on visual inspection. Additionally the content of dissolved water shall not be such as to cause failure when tested according to AS
44、TM D 2713. 6.2 Odour When tested in accordance with the procedure described in Annex A, the odour of the gas shall be characteristic (i.e. distinctive and unpleasant) and detectable down to a concentration in air of 20 % of the lower flammability limit. CAUTION. In order to minimize the exposure of
45、personnel conducting the odour test, it is strongly recommended that the test should only be performed when it has been ascertained that LPG already meets the other specification limits detailed in Table 1 of this European Standard. The test involves the operator inhaling a mixture of LPG vapour and
46、 air. There is a risk that the short-term and/or long-term (8 h TWA reference period) occupational exposure limits for substances contained in the LPG may be exceeded. The operator should consult relevant safety and health regulations and ensure that exposure during the sampling, handling and testin
47、g of LPG does not exceed the prescribed limits. As a guide, and provided the LPG being tested complies with the quality requirements listed in Table 1 of this European Standard, an operator will normally remain within recommended occupational exposure limits provided inhalation of the LPG/air mixtur
48、e does not exceed three 10 s periods during each test and not more than two tests per hour are performed in the course of an 8 h working day. This guidance only takes account of the operators exposure whilst conducting odour tests. Other potential exposures should be assessed in order to estimate to
49、tal exposure. 6.3 Density If information on density is required, the use of ISO 8973 is recommended. 6.4 General When tested by the methods of test given in Table 1, automotive LPG fuel shall comply with the limiting requirements specified in that table. For the minimum vapour pressure four grades, A, B, C and D, are given to allow for seasonal limits to be set nationally for the winter period. In a National annex to this European Standard each country shall indicate which (winter) grade(s) it adopts and s
