Table 3. Relationship between Operating Force and Aging Days at Each Aging Temperature

Agint Temperature (°C) Equation of number of aging days (X, day) and operating force (Y, N)
150 °C Y = -0.168 * log10(X) + 4.28
180 °C Y = -0.417 * log10(X) + 4.28
210 °C Y = -0.719 * log10(X) + 4.28
240 °C Y = -1.96 * log10(X) + 4.28
