The temperature at which the penetration depth of a needle with a cross-sectional area of 1 mm² reaches 1 mm under a specified load, while the oil temperature is steadily increased in the oil, is referred to as VSP.
In oil, the oil temperature is increased at a constant rate (often 50°C/h), and a needle with a cross-sectional area of 1 mm² is applied to the sample with a specified load, with the temperature at which the penetration depth reaches 1 mm being defined as the VSP.
