TS EN 267

TS EN 267 is a standard focused on the definitions, requirements, laboratory testing and marking of forced draught oil burners. This product family covers burners in which combustion air is supplied by a fan or similar forced-air arrangement and the fuel is fed within a defined viscosity range at the burner inlet, so the technical core of the standard is how burner performance is assessed under laboratory conditions.

What the test scope means in practice

The test framework covered by the standard is intended for laboratory testing of forced draught oil burners supplied with a fuel whose viscosity at the burner inlet is from 1.6 mm2/s (cSt) to 6 mm2/s (cSt) at 20 °C. In practical terms, this is relevant to burners using light liquid fuels, where spray formation, mixing quality, flame stability and overall operating behaviour are evaluated in a controlled environment. The stated viscosity range defines the fuel condition within which the test provisions apply.

Why definitions, requirements and marking are grouped together

The terms definitions, requirements and marking serve complementary purposes for the same technical product family. In general technical usage, definitions establish what type of equipment is being described, requirements set the performance and construction expectations to be assessed, and marking defines how essential product information is presented to users. Grouping them together helps manufacturers and users describe the same burner type in a comparable way.

This standard is based on EN 267:1999 and is read alongside referenced documents such as TS EN 230, TS EN 50165, TS 3033 EN 60529 and related standards. In general, forced draught oil burners are used in heating boilers, process-heating systems and similar combustion applications, while this listing specifically reflects the laboratory test and marking framework of the standard.
