3-1. Test method - ISO 14577 and DIN50539 standard 3-2. Indenters - 4 side vickers diamond pyramid indenter 3-3. Measuring hardness ranges - 0.001 ~ 120000N/㎟ 3-4. Test load - measuring load range : 0.1mN ∼ 2000 mN - initial load : 0.04 mN ∼ 0.1 mN - number of steps : 4 ∼ 2000 step - minimum moving time to the next step : 0.1 second 3-5. Indentation depth - min. 0.001㎛ ∼ max. 150 ㎛ 3-6. Accuracy - Test force : under 0.04 mN (0.004gf) ; readability (resolution) : 0.001μN - Indentation depth : under 0.1nm (100pm) ; readability(resolution) : 0.0001 nm 3-7. Zero point of the indenter - Surface contact speed : 0.001 ∼ 0.002 mm/sec. - Accuracy of the zero point : under 1% of 5nm or indentation depth 3-8. Creep test time - min. 1sec. ∼ max. 60sec. [ramp up and ramp down time could be controlled. 3-9. Test time - Standard application Moving time of the indenter to surface of the sample + stabilizing time + time to put load + creep time + time to remove the load = in the range of seconds ∼ several minutes. - ESP application Moving time of the indenter to surface of the sample + (stabilizing time + time to put load + creep time + time to remove the load) x n (test number of times) = in the range of 10 to 20 minutes. |
