29、 and which are used to dispense liquid fuels into the tanks of motor vehicles, boats and light aircraft and into portable containers, at flow rates up to 200 l.min-1. The requirements apply to automatic nozzles dispensing flammable liquid fuels at ambient temperatures from -20 C to +40 C with the po
30、ssibility for an extended temperature range. This European Standard does not apply to equipment dispensing liquefied petroleum gas nor compressed natural gas. This European Standard does not include any requirements for metering performance such as may be specified under the Measuring Instruments Di
31、rective nor those specified under the Electromagnetic Compatibility Directive. Vapour recovery efficiency rates are not considered within this standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative refer
