TS 13343

TS 13343 is a withdrawn service standard that sets rules for authorised services handling general-purpose fluid storage tanks. Its focus is not the tanks alone, but the organisations that carry out maintenance, repair, operation-related service activities, and related support work on those tanks. In practical terms, it establishes a common framework for how such services should be organised, equipped, staffed, and documented.

What this service framework addresses

According to the title and scope, the standard covers structural characteristics, operating arrangements, technical equipment, personnel qualifications, and certification aspects for competent services. In general technical terms, these elements describe whether a service provider has suitable premises, the right tools and equipment, appropriately qualified personnel, and a defined system for delivering the service consistently. For fluid storage tanks, service capability matters because maintenance and repair affect continued usability, reliability, and orderly operation.

Explicit boundaries of coverage

• Milk, cream and similar food storage tanks are excluded.
• Storage tanks for hazardous fluids are excluded.
• Tanks covered by TS 12852, TS 13089 and TS 12420 are excluded.

These exclusions matter because food tanks are governed by hygiene-driven expectations, while hazardous fluids introduce separate safety and suitability concerns. By contrast, general-purpose fluid storage tanks refer to a broader category of tanks used for non-specific liquid storage applications, such as certain water or process-fluid uses depending on context. TS 13343 therefore serves as a service-orientated rule set for the competent organisations working on this tank category, rather than as a product design standard for the tanks themselves.
