a semisolid lubricant, generally consists of a soap emulsified with mineral or vegetable oil. Due to its nature, it requires some different types of testing than do liquids fuels or lubricants.  Among these are penetration, water washout properties, shear stability properties, roll stability, oxidation and the dropping point temperature.  The specification for automotive lubricating greases is ASTM D4950. SAE and NLGI are organizations which also have significant input into the automotive grease specification. Stanhope Seta has been involved in producing instruments for these methods for many years and produce instruments for many of the methods called for in this specification. (Note: There are greases for many other applications than automotive.  In general the measurement of their properties is quite similar.)
