Foreword ISO (the International Organization for Standardization) is a worldwide federation of na
29、tional standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Intern
30、ational organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the
31、rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the
32、possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 3405 was prepared by Technical Committee ISO/TC 28,Petroleum products and lubricants.
33、This third edition cancels and replaces the second edition (ISO 3405:1988), of which it constitutes a technically revision. Annexes A and B form a normative part of this International Standard.

34、Sun Nov 19 15:39:02 GMT+00:00 2006, Uncontrolled Copy, (c) BSI ?1 Petroleum products Determination of distillation characteristics at atmospheric pressure WARNING The use of this International Standard may involve hazardous materials, operations and equipment. This International Standard does not pu
35、rport to address all of the safety problems associated with its use. It is the responsibility of the user of this International Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. 1?Scope This International Standard
36、 specifies a laboratory method for the determination of the distillation characteristics of light and middle distillates derived from petroleum with initial boiling points above 0 ?C and end-points below approximately 400 ?C, utilizing either manual or automated equipment, with the manual procedure
37、being the referee method in cases of dispute, unless otherwise agreed. NOTE?The method is applicable to petroleum products incorporating a minor constitution of components from non- petroleum origin, but the precision data may not apply in all cases. The distillation (volatility) characteristics of
38、hydrocarbons have an important effect on their safety and performance, especially in the case of fuels and solvents. The boiling range gives important information on composition and behaviour during storage and use, and the rate of evaporation is an important factor in the application of many solven
39、ts. Limiting values to specified distillation characteristics are applied to most distillate petroleum product specifications in order to control end-use performance and to regulate the formation of vapours which may form explosive mixtures with air, or otherwise escape into the atmosphere as emissi
40、ons (VOC). 2?Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, partie
41、s to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintai

44、For the purposes of this International Standard, the following terms and definitions apply. 3.1 decomposition point thermometer reading (corrected) which coincides with the first indications of thermal decomposition of the liquid in the flask NOTE?Characteristic indications of thermal decomposition
45、are an evolution of fumes and erratic thermometer readings which usually show a decided decrease after any attempt has been made to adjust the heat. 3.2 dry point thermometer reading (corrected) that is observed at the instant the last drop of liquid evaporates from the lowest point in the flask; an
46、y drops or film of liquid on the side of the flask or on the thermometer are disregarded NOTE?The end-point (final boiling point), rather than the dry point is intended for general use. The dry point can be reported in connection with special purpose naphthas, such as those used in the paint industr
47、y. Also, it is substituted for the end-point (final boiling point) whenever the sample is of such a nature that the precision of the end-point cannot consistently meet the requirements given in clause 12. 3.3 end-point final boiling point maximum thermometer reading (corrected) obtained during the t
48、est NOTE?This usually occurs after evaporation of all liquid from the bottom of the flask. 3.4 initial boiling point thermometer reading (corrected) that is observed at the instant that the first drop of condensate falls from the lower end of the condenser tube 3.5 percent evaporated sum of the perc
49、ent recovered and the percent loss 3.6 percent loss 100 minus the total recovery NOTE?Sometimes called “front-end loss”; this is the amount of uncondensed material lost in the initial stages of the distillation. 3.7 corrected loss percent loss corrected for barometric pressure 3.8 percent recovered volume of condensate observed in the receiving graduated cylinder at any point in the distillation, expressed as a percentage of the charge volume, in connection with a simultaneous temperature reading 3.9 percent recovery maximum percent recover
