Below 6 kV
LABORDATA’s summary of IEC 61340-4-4:2018 specifies Type B fabric breakdown voltage below 6,000 volts. Request the applicable test documentation for your construction.
Low-breakdown-voltage construction
FIBC Type B
Know the material.
Choose the right protection.
Type B bulk bags use low-breakdown-voltage materials to prevent propagating brush discharges. They do not dissipate static charge. Let’s review your product and operation before selecting a bag.
Type B FIBC • Low breakdown voltage • Application-specific selection
Understand the classificationLow breakdown voltage.
Low breakdown voltage.
A specific form of protection.
Type B is made from non-conductive materials. Its electrical breakdown characteristics distinguish it from a conventional Type A bag.
Charge can still accumulate
Low breakdown voltage prevents propagating brush discharges. It does not make the bag conductive or provide the static-dissipation mechanism of Type C or Type D.
Review dust hazards
Selection depends on the product and operating conditions. Type B is not suitable for flammable gas or vapor atmospheres.

Product & environment
Share your product characteristics, dust ignition data, filling and emptying conditions, and site assessment. Identify any flammable gases or vapors.
Bag construction
Define dimensions, safe working load, bag style, lifting loops, filling opening, discharge, printing, and storage needs.
Liners & components
Include the liner specification, coatings, labels, and document pockets. Review the complete package rather than fabric alone.
Documentation & supply
Request design-specific test documentation and operating instructions. Tell us quantities, delivery location, and timing.

Clear requirements.
Informed decisions.
Is Type B an antistatic bag?
No. Type B limits propagating brush discharges through low-breakdown-voltage materials; it does not provide a mechanism to dissipate accumulated static charge.
Does Type B need a bag grounding lead?
Type B has no designed conductive path to earth. Adding a clamp does not turn it into a Type C bag. Grounding requirements for equipment, personnel, and other conductive objects remain part of the site’s operating procedures.
Can Type B be used around flammable gases or vapors?
No. Type B is not suitable where flammable gas or vapor atmospheres are present. Share the complete process environment so the appropriate bag classification can be reviewed.
Can we add a liner?
A compatible liner may be specified, but its electrostatic properties and the complete bag construction require review. Do not substitute a liner without checking the design requirements.
Does Type B also mean food-contact safe or UN certified?
No. Electrostatic classification, food-contact suitability, and UN dangerous-goods qualification address different requirements. Specify each requirement separately and request supporting documentation.
Can you review our existing specification?
Yes. Send the specification, product and process information, bag dimensions, fill weight, liner details, and required documentation. We can help identify points needing clarification.
