6、referred to Inside back coverBS1595-1:1986 ii BSI 08-1999 Foreword This Part of BS1595, 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 requirements of a wide range of indu
7、strial 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 in1950, BS1595 was last revised in1965 and was subsequently amended to become BS1595-1. In
8、the present edition of BS1595-1, a requirement for colour has been introduced and the requirement for relative density has been replaced by one for density at20 C. In addition, the test methods associated with the specification are now published separately as BS1595-2. This standard supersedes BS159
9、5-1:1965, which is withdrawn.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 from legal obligations. Summary of

It does not apply to material for medicinal use or to material sold as “isopropyl alcohol azeotrope”. NOTEThe titles of the publications referred to in this standard
12、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 consist essentially of propan-2-ol (CH 3 ) 2 CHOH. 3 Sampling and size of sample A sample of not less than 1 L shall be taken in accordance wi
13、th BS1595-2. 4 Colour The colour of the material shall not exceed15 Hazen units when measured as described in BS5339. 5 Density The density of the material at20 C shall be notlower than0.785g/mL and not higher than0.787g/mL when determined as described in BS4522. 6 Distillation range When the materi
14、al is distilled as described in BS4591, modified as specified in BS1595-2, the initial boiling point at1013 mbar 1)pressure shall benot lower than81.5 C and the dry point at1013mbar pressure shall be not higher than83.0 C. 7 Residue on evaporation The residue on evaporation of the material shall not
15、 exceed0.002% (m/m) when determined as described in BS4524. 8 Miscibility with water The material shall not show opalescence when tested as described in BS1595-2. 9 Water content The material shall not contain more than0.50%(m/m) of water when determined as described in clause3 of BS2511:1970, using
16、20mL of the material. 10 Alkalinity or acidity The material shall not be alkaline to phenolphthalein and shall not contain more than0.002% (m/m) of acid, calculated as acetic acid (CH 3 COOH) and determined as described in BS1595-2. 11 Aldehydes and ketones The material shall not contain more than0.
