In addition, chemical compatibility refers to the container material being acceptable to store the chemical or for a tool or object that comes in contact with a chemical to not degrade. For example, when stirring a chemical, the stirrer must be stable in the chemical that is being stirred. Many companies publish chemical resistance charts.
Different brands and grades of bottled motor oil at a store. SAE J300 is a standard that defines the viscometric properties of mono- and multigrade engine oils, maintained by SAE International. [1]
The test grease is inserted into the container and the plunger is stroked 60 times while the test apparatus and grease are maintained at a temperature of 25 °C. Once worked, the grease is placed in a penetration test apparatus. This apparatus consists of a container, a specially-configured cone and a dial indicator. The container is filled ...
The measure of the consistency of a lubricating grease is commonly expressed by its NLGI consistency number, defined by the NLGI in the “standard classification of lubricating grease”. The NLGI consistency number is used in several standards: ASTM D4950 , SAE J310 and ISO 6743-9 “lubricants, industrial oils and related products (class L ...
The viscosity index (VI) is an arbitrary, unit-less measure of a fluid's change in viscosity relative to temperature change. It is mostly used to characterize the viscosity-temperature behavior of lubricating oils.
Ramsay grease is an old composition of paraffin wax, vaseline and natural rubber, usable up to about 25 °C, for low vacuums to about 1 Pa. Krytox is a fluorether-based vacuum grease, useful from −75 to over 350 °C, not flammable even in liquid oxygen, and highly resistant to ionizing radiation. Polyphenyl ether greases
