Acceleration Factor

For the IPL relationship the acceleration factor is given by:

[math]\displaystyle{ {{A}_{F}}=\frac{{{L}_{USE}}}{{{L}_{Accelerated}}}=\frac{\tfrac{1}{KV_{u}^{n}}}{\tfrac{1}{KV_{A}^{n}}}={{\left( \frac{{{V}_{A}}}{{{V}_{u}}} \right)}^{n}} }[/math]

where:
• [math]\displaystyle{ {{L}_{USE}} }[/math] is the life at use stress level.

• [math]\displaystyle{ {{L}_{Accelerated}} }[/math] is the life at the accelerated stress level.

• [math]\displaystyle{ {{V}_{u}} }[/math] is the use stress level.

• [math]\displaystyle{ {{V}_{A}} }[/math] is the accelerated stress level.
