Because it is aqualitative test, its use would require agreement between user andsupplier.NOTE 3Instrumental Pt-Co color d
16、etermined by Test Method D5386has been shown to have no statistically significant difference from Pt-Cocolor determined by Test Method D1209. However, it is not knownwhether diacetone alcohol was part of the sample set included in theinterlaboratory study.4. Sampling4.1 The material shall be sampled
17、 in accordance withPractice E300.5. Test Methods5.1 The properties enumerated in this specification shall bedetermined in accordance with the following ASTM testmethods:5.1.1 Apparent Specific GravityDetermine the apparentspecific gravity by any convenient method that is accurate tothe third decimal
18、 place, the temperature of both specimen andwater being 20 or 25C. (See Guide D268 and Test MethodD4052.)5.1.2 ColorTest Method D1209.NOTE 4Diacetone alcohol has a tendency to develop yellow color thatis hastened by contact with iron or rust during storage. Protection fromiron is obtained with a zin

20、 This exception to the suggestion in Note 3 of Test Method D1078is specifically applicable to diacetone alcohol. Particular care should alsobe given to the heating rate so that the initial boiling point is obtainedwithin the specified time of 5 to 10 min.5.1.4 Nonvolatile MatterTest Method D1353.5.1
