The standard normal curve is symmetrical.
the standard normal curve 2
The area under the standard normal curve is 1.
To prepare the standard curve you will need linear graph paper, semi-log graph paper and absorbance. You can define your standard curve by finding the absorption or percent plot on the Y axis.
It is a normal curve with mean = 0 and variance = 1.
Mean = 0 Standard Deviation = 1
The values of many curves cannot be calculated analytically: the process requires painstaking numerical estimation. The values of a standard curve can be calculated once and published for ready reference. This means that, given any other curve in the same family, it is possible to transform it to the standard curve and the reference values can be used.

The Standard temperature-time curve ISO 834, also known as the Cellulosic curve and/or the standard nominal fire curve, is used to test the fire resistance of materials subjected to a category "A" fire hazard i.e. with the fire hazard rating based on the burning rate of general combustible building materials and building contents. The ISO 834 is the least "intensive" of the fire curves.
