Accuracy of the some components' values
As far as I know, the tolerance specification of a resistor is usually given as the initial accuracy of the resistor when it is delivered to the customer, measured at 25 C.

This is supported by a document from Vishay:



I would expect to be able to find a similar clarification in some documentation from Panasonic or any other reputable resistor manufacturer, but I couldn't find it with a few minutes looking around their website.


  I wonder if the accuracy means 'just the absolute accuracy of the resistance', which means the temperature will not affect to accuracy, or not.


The change in resistance due to temperature is a further error beyond the initial tolerance specification.
