🔍 Key Concepts

• Grease properties such as hardness/softness, melting behavior, and flow characteristics • Meaning of pour point and drop point in lubrication • How penetration tests are used to classify grease consistency (NLGI grades)

💭 Think About

• Which test or number directly measures how deeply a standard cone or object sinks into a grease sample? • Which indicator is more about the temperature at which grease starts to flow or drip rather than how hard or soft it is at room temperature? • Think about how grease consistency (like NLGI #2 vs NLGI #0) is usually specified in maintenance manuals—what number describes that?

✅ Before You Answer

• Match the term that is specifically linked to consistency/hardness (soft vs stiff) of grease, not temperature behavior. • Confirm which indicators (pour point and drop point) relate mainly to low- and high-temperature limits of oils/greases. • Recall that standard grease classifications are based on a consistency test using a cone penetration measurement.
