International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference EN 61340-4-4:2005
Title Electrostatics - Part 4-4: Standard test methods for specific applications - Electrostatic classification of flexible intermediate bulk containers (FIBC)
Project Number 16379
Abstract/Scope Describes procedures for evaluating the ignition risk presented by electrostatic discharges from FIBC to flammable or explosive environments. The requirements of this standard are applicable to all types of FIBC, tested as manufactured, prior to usage, intended for use without liners in flammable or explosive environments with minimum ignition energy of more than 0,14 mJ, and where the charging currents do not exceed 3,0 A. NOTE 0,14 mJ is the minimum ignition energy normally quoted for methanol. Although more sensitive materials exist, methanol has the lowest minimum ignition energy of any material that is likely to be present when FIBC are emptied. 3,0 uA is the highest charging current likely to be found in common industrial processes. This combination of minimum ignition energy and charging current represents the most severe conditions that might be expected in practice. Compliance with the requirements of this standard does not mitigate the need for full risk assessment. The test methods included in this standard may be used in association with other performance requirements, for example when a risk assessment has shown the minimum ignition energy of concern is less than 0,14 mJ or charging currents greater than 3,0 uA are present.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
