- The instrument is designed and made as per the National Standard of
People's Republic of China GB/T4985 "Test Methods forPenetration of Petroleum Wax". The penetration needle and other accessories equipped with the
instrument can meet the requirements of GB/T4985.
- The penetration of wax is expressed as the depth that a standard
needle of 100 g vertically penetrates into a sample without
measurable fraction in 5 seconds. It is used to evaluate the
hardness of wax.
- In general, the testing temperature for wax penetration test is 25
°C. You can make measurement for needle penetration at a
temperature in the range of 25~55 °C. But you should report the
test temperature if it is not 25 °C.
- The unit of wax penetration is 0.1 mm. Itcan be read directly from the display.
