What is ASTM D217?

ASTM D217, 2021 Edition, July 1, 2021 – Standard Test Methods for Cone Penetration of Lubricating Grease. These test methods cover four procedures for measuring the consistency of lubricating greases by the penetration of a cone of specified dimensions, mass, and finish.

What does Nlgi mean in grease?

Lubricating
Traditionally, a grease’s stiffness is indicated by its penetration value and is evaluated using the standardized National Lubricating Grease Institute (NLGI) grade chart. The NLGI number is a measure of the grease’s consistency as indicated by its worked penetration value.

What Nlgi 1.5 grease?

Multipurpose Greases, NLGI Grade: 1.5, Silicone Grease Thickener. This low-viscosity grease is suitable for applications with rolling bearings. It has a soft consistency somewhere between tomato paste and peanut butter. Silica offers excellent heat resistance and oxidative stability.

What does NGLI stand for?

NLGI

What is drop point of grease?

The dropping point of a grease is the temperature at which it passes from a semi-solid to a liquid state. The dropping point test determines the cohesiveness of the oil and thickener of a grease. The dropping point of a grease is the temperature at which it passes from a semi-solid to a liquid state.

Is Nlgi the same as EP?

This tells us two things, EP 2 grease is a NLGI Grade 2 and it is fortified with Extreme Pressure (EP) additives. This tells us nothing else about the thickener type, base oil type or viscosity of the base oil. The correct NLGI grade is an important consideration because not all grease applications are the same.

What is the difference between NLGI #1 and 2?

There are two basic types of grease for most equipment and machinery applications: NLGI #1 grease and NLGI #2 grease. Less thickener makes a #1 grease more tractable and slippery, while #2 grease has more thickener, making it stiffer and great for all-purpose applications.

How do you measure the drop point of grease?

To calculate the dropping point of the grease, the recorded temperature of your sample is subtracted from the heater block temperature. And that value is added to the sample temperature to determine the Dropping Point. A Dropping Point is most often performed on any soap-thickened grease.

What is drop point of lubricant?

The dropping point of a lubricating grease is an indication of the heat resistance of the grease and is the temperature at which it passes from a semi-solid to a liquid state under specific test conditions. It is dependent on the type of thickener used and the cohesiveness of the oil and thickener of a grease.
