National annex NB (informative) Cross-references

Relates to fixed discrete resistors with the exception of those whose prime use requires that resistance is temperature or voltage dependent. Coverage includes: quality assessment procedures, assessed process average procedures, standard atmospheric conditions, temperature rise, voltage coefficient, and insulation resistance. Also gives detailed annexes.
