TS 13905

TS 13905 addresses the general rules for workplaces that perform installation, maintenance, service, commissioning, and removal from service of air-conditioning and refrigeration equipment, heat pumps, fire extinguishing systems, and electrical switchgear that operate with or contain fluorinated greenhouse gases. Its focus is the organisational and technical framework of the service workplace, rather than the detailed design of the equipment itself.

Workplace organisation and technical readiness

The standard covers general provisions on structural features, business administration, technical equipment, employee competence, and safety. In practical terms, this reflects the need for controlled handling of fluorinated gases, including leak-sensitive equipment, proper recovery and charging practices, suitable tools, records, and disciplined workflows. Fluorinated greenhouse gases are refrigerants or insulating/media gases used in cooling, heating, and related systems; their environmental significance makes competent servicing and suitable workplace arrangements especially important.

A common framework across multiple applications

The scope also extends to fire extinguishing systems and electrical switchgear, showing that fluorinated gases are used in more than refrigeration alone. From a general technical perspective, the shared concerns are safe work areas, appropriate personal protective equipment, electrical safety, and organised service procedures. The standard provides the general workplace framework for these activities; it does not replace product-specific performance standards or detailed equipment design requirements.
