Описание (английский):

ISO 11755:2005 specifies the requirements for inspection before, during and after the time of filling for cylinder bundles for compressed and liquefied gases, also referred to as bundles. ISO 11755:2005 does not apply to acetylene bundles. ISO 11755:2005 does not apply to bundles when they are a part of a battery vehicle.

Overview

ISO 11755:2005 - Gas cylinders - Cylinder bundles for compressed and liquefied gases (excluding acetylene) - Inspection at time of filling - defines inspection requirements to be carried out before, during and after filling of transportable gas cylinder bundles. The standard applies to bundles (frames with two or more cylinders) used for compressed and liquefied gases, but explicitly excludes acetylene bundles and bundles that form part of a battery vehicle. ISO 11755:2005 supports safe filling practice, contamination control and prevention of overfilling.

Key topics and requirements

The standard focuses on practical, safety-critical checks and documentation:

Inspection prior to filling

Verify legal permissibility for filling in that country and that periodic inspection/test dates are valid.
Confirm compatibility of bundle with the gas, filling pressure or filling weight, and legibility of markings (tare weight, maximum permissible filling weight or maximum permissible operating pressure).
Visual checks on frame integrity, restraints, lifting attachments, manifold, flexible hoses, valves and visible cylinder damage (apply rejection criteria in ISO 6406 / ISO 10461 / ISO 11623 as appropriate).
Ensure bundle is free of contamination (positive residual pressure or mass check for liquefied gases).

Bundle identification

Mandatory permanent marking/labels: design/approval numbers, country of approval code, inspection stamp, initial inspection date, test pressure (PH...BAR), tare weight and filling weight (if filled by mass), working pressure (PW...), water capacity (L), manufacturer mark and serial number.

Inspection during filling

For liquefied gases with individual closable valves, prevent overfilling by either dismantling and filling one cylinder at a time or using separate filling control devices for each cylinder.
Monitor for leaks - heightened vigilance for toxic, flammable or pyrophoric gases.

Inspection after filling

Verify no overfilling (pressure corrected for reference temperature or mass checked against maximum permissible filling weight on appropriate scales).
Confirm permanent marking/labeling, absence of leaks at main outlet and cylinder valves, and closure of valves required for transport.

Applications and users

ISO 11755:2005 is primarily used by:

Gas filling stations and industrial gas suppliers

Cylinder bundle manufacturers and maintenance workshops

Independent inspection bodies and authorized testers

Transport and logistics operators handling bundled cylinders

Safety officers and compliance teams in industries using compressed or liquefied gases

Adoption of ISO 11755 helps reduce risk of overfill, contamination and mechanical failure during filling, transport and use.
