18、 biological origin”, the secretariat of which is held by NEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2008, and conflicting national standards shall be withdrawn at the latest by Mar

19、ch 2008. This document supersedes EN 13016-1:2000, which has been updated by the explicit addition of DVPE to better reflect its use in EN 228 1. The range for the instrument verification fluids has been widened and typical/consensus values added in an informative Annex. A revision to the sample int

20、roduction has been included as this was part of the original procedure that precision was based on. Editorial clarification of the sampling, sample preparation and calibration of the pressure transducer have been included. The precision statements have been updated following a global evaluation in 2

21、003. EN 13016 consists of the following parts, under the general title Liquid petroleum products - Vapour pressure: Part 1: Determination of air-saturated vapour pressure (ASVP) and calculated dry vapour pressure equivalent (DVPE). Part 2: Determination of absolute vapour pressure (AVP) between 40 C

22、 and 100 C. This part is based on and developed in parallel with IP 394 2 and ASTM D 5191 3. It describes a general determination method, whereas part 2 describes a determination method at elevated temperatures. According to the CEN/CENELEC Internal Regulations, the national standards organizations

23、of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Sl

Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 11/12/2007 07:25, Uncontrolled Copy, (c) BSIEN 13016-1:2007 (E) 4 Introduction Vapour pressure is used as a classification criterion for the safe handling and carriage of petroleum

25、 products, feedstocks and components; it has a relationship to the potential for hydrocarbon emissions, under uncontrolled conditions, and thus is the subject of environmental scrutiny. Vapour pressure limitations are often imposed to prevent pump cavitation during transfer operations. Vapour pressu

26、re is one measure of the volatility characteristics of fuels used in many differing types of engines with large variations in operating temperatures. Fuels having a high vapour pressure may vaporize too readily in the fuel handling systems, resulting in decreased flow to the engine and possible stop

27、page by vapour lock. Conversely, fuels of low vapour pressure may not vaporize readily enough, resulting in difficult starting, slow warm-up and poor acceleration.

28、ropean Standard specifies a method for the determination of the total pressure, exerted in vacuo, by volatile, low viscosity petroleum products, components, and feedstocks containing air. A dry vapour pressure equivalent (DVPE) can be calculated from the air containing vapour pressure (ASVP) measure

29、ment. The conditions used in the test described in this standard are a vapour-to-liquid ratio of 4:1 and a test temperature of 37,8 C. For referee testing the requirement to employ 1 l sample containers is mandatory. However, due to sample container size restrictions in taking automatic samples from

30、 vapour-locks either onboard a ship or from some land based storage tanks, the precision for 250 ml containers forms part of this standard and shall be used for referee purposes. NOTE 1 This standard states precision for both 1 l and 250 ml sample containers. Annex A provides information on the prec

31、ision values when using 50 ml at 37,8 C or using 1 l samples at a test temperature of 50,0 C. The equipment is not wetted with water during the test, and the method described is therefore suitable for testing samples with or without oxygenates; no account is taken of dissolved water in the sample. T

32、his method described is suitable for testing air-saturated samples that exert an air-saturated vapour pressure of between 9,0 kPa and 150,0 kPa at 37,8 C. This document is applicable to fuels containing oxygenated compounds up to the limits stated in the relevant EC Directive 85/536/EEC 4. NOTE 2 Fo

33、r the purposes of this European Standard, the term “% (m/m)“and “% (V/V)” are used to represent the mass, respectively the volume fraction. WARNING Use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems ass

34、ociated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. 2 Normative references The following referenced documents are indispensable for the application

38、.3 dry vapour pressure equivalent DVPE vapour pressure equivalent value calculated by a statistical correlation equation to a dry Reid vapour pressure 4 Principle A cooled air-saturated sample of known volume is injected into a thermostatically controlled evacuated chamber, or into a chamber that is

39、 evacuated by means of a moveable piston after sample introduction, the internal volume of which is five times that of the total test portion introduced into the chamber. After injection into the chamber, the sample is allowed to reach thermal equilibrium at the test temperature 37,8 C. The resultin

40、g total pressure in the chamber is equivalent to the vapour pressure of the sample and the partial pressure of the dissolved air and is measured using a pressure sensor and indicator. The measured total vapour pressure can be converted to a dry vapour pressure equivalent (DVPE) by use of a correlati
