This generic specification relates to passive filter units for electromagnetic interference suppressionfor use within, or associated with, electronic or electrical equipment and machines.Both single and multi-channel filters within one enclosure are included within the scope of thisgeneric specification.Filters constructed of capacitive elements where the inductance is inherent in the constructionof the filter are within the scope of this specification. Similarly, filters constructed of inductiveelements where the capacitance is inherent in the construction of the filter are also within thescope of this generic specification. The manufacturer should state whether a given componentis to be designed as a capacitor, an inductor or a filter.The filter units within the scope of this generic specification are further distinguished as thosefor which safety tests are appropriate (e.g. those connected to mains supplies) and those forwhich such tests are not appropriate. A separate sectional specification covers the passivefilter units for which safety tests are appropriate.This generic specification establishes standard terms, inspection procedures and methods oftest for use in sectional and detail specifications within the IECQ-CECC system for electroniccomponents.
Is a supplementary document to the sectional specification and contains requirements for style and layout and minimum content of detail specifications. In the preparation of detail specifications, the content of 1.4 of the sectional specification shall be taken into account. The use of IEC 60939-2-2 may be more appropriate for components where approval and requalification tests contribute considerably to the cost of the product, whereas the employment of this specification may be necessary for components manufactured in mass production. This specification offers the assessment levels D and DZ (Zero defect).
Forms the basis for a uniform procedure for a common Safety Mark. It implements the approval schedule for the safety test described in IEC 60939-2, requires a declaration of design for parameters relevant to safety and prescribes conformance tests to be conducted on every lot prior to its release and requalification tests depending on changes to the declared design.
Applies to passive filter units for electromagnetic interference suppression which fall within the scope of the Generic Specification IEC 60939-1. The scope of this Sectional specification is restricted to passive filter units for which safety tests are appropriate. This implies that filters specified according to this Sectional specification will either be connected to mains supplies, when compliance with the mandatory tests of Table 3 is necessary, or used in other circuit positions where the equipment specification prescribes that some or all of these safety tests are required.

IEC 60939-2-2:2004 forms the basis for a uniform procedure for a common Safety Mark. It implements the approval schedule for the safety test described in IEC 60939-2, requires a declaration of design for parameters relevant to safety and prescribes conformance tests to be conducted on every lot prior to its release and requalification tests depending on changes to the declared design.
This Sectional specification applies to passive filter units for electromagnetic interference suppression which fall within the scope of the Generic Specification IEC 60939-1. The scope of this Sectional specification is restricted to passive filter units for which safety tests are appropriate. This implies that filters specified according to this Sectional specification will either be connected to mains supplies, when compliance with the mandatory tests of Table 3 is necessary, or used in other circuit positions where the equipment specification prescribes that some or all of these safety tests are required. This Sectional specification applies to passive filter units which will be connected to an a.c. mains or other supply with a nominal voltage not exceeding 1 000 V a.c., with a nominal frequency not exceeding 400 Hz, or 1 000 V d.c.
