23、00 2007, Uncontrolled Copy, (c) BSI EN 589:2004 (E) 4 1 Scope This European Standard specifies requirements and test methods for marketed and delivered automotive LPG (Liquefied Petroleum Gas). It is applicable to automotive LPG for use in LPG engine vehicles designed to run on automotive LPG. NOTE:
24、For the purposes of this European Standard, the term “% (V/V)” is used to represent the volume fraction. WARNING - Attention is drawn to the risk of fire 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
25、hydrocarbon liquid which is normally stored under pressure. If the pressure is released large volumes of gas will be produced which form flammable mixtures with air over the range of approximately 2 % (V/V) to 10 % (V/V). This European Standard involves the sampling, handling and testing of LPG. All
26、 procedures should be conducted away from sources of ignition such as naked flames, unprotected electrical equipment and electrostatic hazards. Testing should be performed as far as practicable under an electrically-safe ventilation hood. LPG in the liquid form can cause cold burns to the skin. Prot
27、ective 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 should not be exposed to atmospheres containing more than 1 800 mg/m3 over an 8 h time-weighted average (TWA) reference period,
28、or more 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 and LPG vapour. Particular attention is drawn to the cautionary statement provided in A.1, where this method is referred to. 2 Nor
29、mative references This European Standard incorporates by dated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of th

The national r
38、equirements shall be set out in detail or shall be referred to by reference in a national annex to this European Standard. In view of the sensitivity of some of the test methods referred to in this European Standard, particular attention shall be paid to compliance with any guidance on sampling cont
39、ainers which is included in the test method standard. NOTE 1It is important that the sampling procedure is followed in detail in order to avoid evaporation losses. NOTE 2Before sampling from the dispenser hose, 20 l of product should be pumped or recirculated, in order to obtain a representative sam

For the minimum vapour pre
42、ssure, five grades, A, B, C, D and E are given to allow for seasonal limits to be set nationally for each period of the year. In a national annex to this European Standard, each country shall indicate which grade(s) it adopts to achieve a minimum vapour pressure of 150 kPa (gauge) throughout the ent
43、ire year and shall detail the date range in which the selected grade applies.
