7、thanol for industrial use. Although applicable to the material in general, it includes all the test methods required to assess compliance with the requirements of BS507 and BS3591. In preparing this standard, the opportunity has been taken to implement, without technical alteration, the majority of

8、the International Standards describing test methods for ethanol. These have been prepared, with the active participation of the UK, by Technical Committee47, Chemistry, of the International Organization for Standardization (ISO), as separate parts of ISO1388 and constitute the revision of ISO Recomm

9、endation1388. NOTEAnnexes in each part of the International Standard, which are intended for information only and which serve no useful purpose in the British Standard, have not been included. In addition, references in the texts to International Standards have been replaced, where possible, by refe

10、rences to the corresponding British Standards. As a consequence the standards are not dual-numbered. Subsequent International Standards in the series, if approved by the UK, will be published as further Parts of this British Standard, without technical alteration. A British Standard does not purport

11、 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 confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cove

12、r, pagesi andii, pages1 and2, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS6392-0:1983 BSI 12-1999 1 1 Scope This Part of this British Sta

13、ndard comprises a general introduction for this series of test methods for ethanol for industrial use and gives instructions which are generally applicable to the entire series. Instructions relating to sampling and to preparation of the test report correspond to the instructions given in ISO1388-1.

14、 The remainder are of general application in British Standard test methods. Table 1 gives the relationship of the Parts of the standard to the corresponding Parts of ISO1388. It also indicates the British Standards corresponding to the general test methods specified in ISO1388-1 as being applicable

15、to ethanol. NOTEThe titles of the publications referred to in this standard are listed on the inside back cover. 2 Sampling 1) Store the laboratory sample in a clean, dry and airtight, ground glass stoppered bottle, or a screw-capped bottle fitted with a polyethylene cone insert, of such capacity th

16、at it is almost filled by the sample. If it is necessary to seal the bottle, take care to avoid any risk of contamination of the contents. NOTE 1Sufficient ullage should be left in the bottle to avoid excessive pressure changes that could arise from temperature variations during storage and handling

17、. About10% ullage is recommended. NOTE 2A sample of not less than2500mL is necessary for performing all the tests described in this standard. 3 Ethanol Unless otherwise specified in a particular method, the ethanol used as a reagent in these determinations may be replaced for these purposes by indus

18、trial methylated spirits, 95% (V/V) complying with BS3591. It should be noted that the use of industrial methylated spirits is governed by The Methylated Spirits Regulations1983 (S.I. 1983, No. 252). It is not permissible to use duty-free ethanol, received under the provisions of The Alcoholic Liquo

19、rs Duties Act1979, Section10, for purposes for which industrial methylated spirits is an acceptable alternative to ethanol. 4 Water Unless otherwise specified in a particular method, water complying with BS3978 is suitable for use in these determinations. 5 Test report The test report, for each dete

20、rmination, should contain the following information: a) an identification of the sample; b) the reference to the method used; c) the results, and the method of expression used; d) any unusual features noted during the determination; e) any operation not included in the appropriate Part of BS6392 or

21、in the British Standards to which reference is made, or regarded as optional. 1) Additional guidance on sampling is given in BS5309-1 and BS5309-3.BS6392-0:1983 2 BSI 12-1999 Table 1 Methods of test for ethanol: relationship between British Standards and International Standards BS 6392 Part no.
