Standardized (ASTM) Testing

Hydrometer ASTM Method E 100-95 (Reapproved 2001) Standard Specifications for ASTM Hydrometers

This specification covers glass hydrometers graduated in systems required by the various tests in which their use is required. The range that can be measured is 0.650 to 1.500.

Density Pycnometer

General Procedure for Density and Specific Gravity Using Weight per Gallon Cup

This procedure is used to determine the density of a liquid by use of a weight per gallon cup. This cup is a special rugged pycnometer, especially designed for the determination of a density at a single temperature (25°C), with an accuracy sufficient for most industrial applications. Specific gravity can be calculated from the measured density.

Refractive Index:

ASTM D1218-99 Standard Test Method for Refractive Index and Refractive Dispersion of Hydrocarbon Liquids

This procedure describes the method to measure the refractive index on a wide variety of liquid samples using the Milton Roy Abbe-3L refractometer. It has a standard range of 1.30 to 1.71 n, and can be operated with rigid temperature control.

General Procedure for Determination of pH

This procedure describes the method to measure the pH of a sample using an analog pH meter.

Viscosity

General Procedure for Brookfield Viscosity

This procedure is used to determine the viscosity of materials in the range of 5 to 100,000 cps. The Brookfield viscometer measures the amount of drag produced by rotating a calibrated spindle in a liquid.

Conductivity

General Procedure for Determination of the Conductivity of Liquid Solutions
Range of conductivity from 0.0 to 199.9 mSiemen.

Evaluation of Wetting Agents

AATCC Test Method 17-1999

This test method determines the efficiency of ordinary commercial wetting agents.
