scope:

The scope of this recommendation is primarily limited to passive band-pass filters in the frequency range about 10 kHz to 100 MHz,which are commercially available as separate and independent units. Filters which are integrated into a larger system are not considered here. It is not the aim of this recommendation to explain theory, nor to attempt to cover all the eventualities which may arise in practical circumstances. This guide draws attention to some of the more fundamental questions which should be considered by the user before he places an order for a unit for a new application. Such a procedure will be the user's insurance against unsatisfactory performance.
