Disintegration test

why we are dissolving dispersible tabs in 25 +_2 degree centegrade ,why not in our room temperature ???

25 is room temp.

For scientific work, room temperature is taken to be about 20 to 25 degrees Celsius with an average of 23 °C (about 73.4 Fahrenheit (°F), 528 to 537 degrees Rankine (°R), or 293 to 298 kelvins (K)). For numerical convenience, either 20 °C or 300 K is often used.
