7、08:03:42 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 1595-1:1986 ii BSI 08-1999 Foreword This Part of BS 1595, which has been prepared under the direction of the Chemicals Standards Committee, comprises a specification for propan-2-ol (previously known as isopropyl alcohol) to meet the requirement
8、s of a wide range of industrial users. It does not, however, apply to material for medicinal use, requirements for which are included in the British Pharmacopoeia, or to material sold as “isopropyl alcohol azeotrope”. First published in 1950, BS 1595 was last revised in 1965 and was subsequently ame
9、nded to become BS 1595-1. In the present edition of BS 1595-1, a requirement for colour has been introduced and the requirement for relative density has been replaced by one for density at 20 C. In addition, the test methods associated with the specification are now published separately as BS 1595-2
10、. This standard supersedes BS 1595-1:1965, which is withdrawn. A British Standard does not purport 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 fr
11、om legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 and 2, 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 amend
12、ment table on the inside front cover.

It does not apply to mat
13、erial for medicinal use or to material sold as “isopropyl alcohol azeotrope”. NOTEThe titles of the publications referred to in this standard are listed on the inside back page. 2 Description The material shall be clear and free from matter in suspension, as assessed by visual inspection, and shall
14、consist essentially of propan-2-ol (CH3)2CHOH. 3 Sampling and size of sample A sample of not less than 1 L shall be taken in accordance with BS 1595-2. 4 Colour The colour of the material shall not exceed 15 Hazen units when measured as described in BS 5339. 5 Density The density of the material at
15、20 C shall be not lower than 0.785 g/mL and not higher than 0.787 g/mL when determined as described in BS 4522. 6 Distillation range When the material is distilled as described in BS 4591, modified as specified in BS 1595-2, the initial boiling point at 1013 mbar1) pressure shall be not lower than 8
16、1.5 C and the dry point at 1013 mbar pressure shall be not higher than 83.0 C. 7 Residue on evaporation The residue on evaporation of the material shall not exceed 0.002 % (m/m) when determined as described in BS 4524. 8 Miscibility with water The material shall not show opalescence when tested as d
17、escribed in BS 1595-2. 9 Water content The material shall not contain more than 0.50 % (m/m) of water when determined as described in clause 3 of BS 2511:1970, using 20 mL of the material. 10 Alkalinity or acidity The material shall not be alkaline to phenolphthalein and shall not contain more than
18、0.002 % (m/m) of acid, calculated as acetic acid (CH3COOH) and determined as described in BS 1595-2. 11 Aldehydes and ketones The material shall not contain more than 0.10 % (m/m) of aldehydes and ketones, calculated as acetone (CH3COCH3) and determined as described in BS 1595-2. 1) 1 mbar = 100 N/m
