This paper presents methods for performance evaluation of the K Bessel functions. Accuracy estimates are based on comparisons involving the multiplication theorem. Some ideas for checking robustness are also given. The techniques used here are easily extended to the Y Bessel functions and, with a little more effort, to the I and J functions. Details on a specific implementation for testing the K Bessel functions are included.
