Load-wear index
Witryna1.1.1 Load-wear index (formerly Mean-Hertz load). 1.1.2 Weld point by means of the four-ball extreme-pressure (EP) tester. 1.2 For the determination of the load-carrying properties of lubricating greases, see Test Method D2596. 1.3 The values stated in SI units are to be regarded as standard. WitrynaThe weld load is reported in kg (kilograms) or N (Newtons) and the higher the number, the better in extreme pressure characteristics. The 10 loads prior to the weld are used to calculate the LWI (Load Wear Index). This relates to how high of a load the lubricant will go prior to the welding without the lubricant film failing.

WitrynaFull Description. 1.1 This test method covers the determination of the load-carrying properties of lubricating greases. Three determinations are made: 1.1.1 Load-Wear Index (formerly called Mean-Hertz Load), 1.1.2 Weld Point, by means of the Four-Ball Extreme-Pressure (EP) Tester, and. http://www.mcinnisusa.com/public/ASTM_D_4950_Grease%20Comparison.pdf

WitrynaLoad-Wear Index (LWI), reported in kg, quantifies the relative wear protection under load of a lubricant. A higher load-wear index indicates a more effective extreme pressure lubricant. Last Non-Seizure Load (LNSL), reported in kg, is the highest load at which elasto-hydrodynamic lubrication is in effect before the transition to boundary ... short closing remarks speechWitrynaAt the highest load the lubricant can stand the boundary film is lost and welding occurs. This test is very good at comparing the extreme pressure and boundary lubrication properties of comparative samples or competitive types of formulations. The Load Wear Index Value, Last Non Seizure, Last Seizure and Weld Load are reported. Price: … short clotheslineWitrynaThe evolution of wear with increasing loads in a load-wear index sequence was analyzed. Wear on the test balls appear to nearly unaffected for loads up to 315 kg. Above 400 kg, there was significant influence with a lower wear scar for a slower ramp up-time of 0.95 secs compared to 0.15 secs (Figure 4). Figure 4. short closing remarks for a programWitrynaThe load wear index (LWI), is the load-carrying property of a lubricant. It is an index of the ability of a lubricant to minimize wear at applied loads.
