7. Reagents and Materials
7.1 Acetone - (Warning - Danger - Extremely fammable. Vapors can cause fire.)
7.2 Methanol - (Warning - Danger - Flammable. Vapor harmful.)
7.3 Petroleum Naphtha - (Warning - Combustible vapor harmful.)
7.4 Calibration Oils - Low-cloud point Newtonian oils of known viscosity and viscosity/temperature functionality. Approximate viscosities at certain temperatures are listed in Table 1, whereas exact viscosities are supplied with each standard.
NOTE 4 - Blind reference samples are available from the supplier of the calibration oils for checking on the shear rate of the viscometric cell and the overall procedure.
8. Hazards
8.1 Observe both toxicity and flammability warnings that apply to the use of methanol, acetone, and petroleum naphtha.
8.2 If methanol is leaking from the apparatus, repair the leak before continuing the test.
