ISO 10414-2:2011 provides standard procedures for determining the following characteristics of oil-based drilling fluids:

drilling fluid density (mud weight);
viscosity and gel strength;
oil, water and solids concentrations;
alkalinity, chloride concentration and calcium concentration;
electrical stability;
lime and calcium concentrations, calcium chloride and sodium chloride concentrations;
low-gravity solids and weighting material concentrations.

The annexes provide additional test methods or examples that can optionally be used for the determination of:

shear strength
oil and water concentrations from cuttings;
drilling fluid activity;
aniline point;
lime, salinity and solids concentration;
sampling, inspection and rejection;
rig-site sampling;
cuttings activity;
active sulphides;
calibration and verification of glassware, thermometers, viscometers, retort kit cups and drilling fluid balances;
permeability plugging apparatus with set-screw secured end cap;
permeability plugging apparatus with threaded end cap;
elastomer compatibility;
sand content of oil-based fluid;
identification and monitoring of weight-material sag;
oil-based drilling fluid test report form.
