Standard tolerance on ‘general mouldings’ and timber species.
Industry norm is approximately +/- 0.25mm-0.5mm
Due to the fact that:
Being a natural product there are many variables that can lead to a shrinking / change of diameter/ size of timber. For example, if the timber was moulded on a warmer more humid day and the day of application was measured on a cooler drier day, this would lead to a variation in size.
The age of the tree and from which part of the log a particular piece came from can also lead to variation.
Shrinkage and expansion rates of timber are based on standards set from historical data. These are statistical models based on averages and standard deviations. At times there can be outliers in shrinkage or expansion rates which will lead to the product being outside of the tolerance ranges.
