scope:

This part of IEC 61340 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 µA. 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 µA are present.
