SIST EN 293:2000

• Abstract:

  This European standards applies to oil pressure atomizing nozzles without backflow - herein called atomizing nozzles - with a nominal throughout <= 6,30 kg/h at 10 bar with a fuel oil. They are characterized by the requirements concerning the operational function according to clause 5.

SIST EN 293:2000 is the Slovene adoption of EN 293:1992 on oil pressure atomizing nozzles. It gives minimum requirements and testing for oil pressure atomizing nozzles without backflow, for use with fuel oil in the covered capacity range. Engineers, quality staff, and buyers use it to check whether a nozzle type falls within the standard and how its operational function is judged.

What does SIST EN 293:2000 specify?

SIST EN 293:2000 applies to oil pressure atomizing nozzles without backflow, called atomizing nozzles in the standard. It covers nozzles with a nominal throughput up to 6.30 kg/h at 10 bar with fuel oil.

The document is organized around the operational-function requirements referenced in clause 5. In practice, that means the standard is not just a product label - it is used when a nozzle is being checked against the operating behavior expected for this nozzle type.

What are the key requirements of SIST EN 293:2000?

SIST EN 293:2000 focuses on a narrow nozzle category and on how that category is tested. The most important point for users is whether the nozzle they are handling matches the covered type and the covered rating conditions.

• Nozzle type - the standard applies to oil pressure atomizing nozzles without backflow. In practice, a user should first confirm the nozzle design is the no-backflow type before using this standard for evaluation.
• Capacity range - the covered nozzles have a nominal throughput up to 6.30 kg/h. This matters because catalog data and test results only fit the standard when the nozzle is in this range.
• Reference test condition - the throughput is stated at 10 bar with fuel oil. That means comparisons should be made at the same pressure and fuel basis, not from different operating conditions.
• Minimum requirements and testing - the title shows that the document combines what the nozzle must meet with how it is checked. For users, this links product acceptance directly to test practice.
• Operational function - the scope points to clause 5 for the operational-function requirements. This is the performance focus of the standard, so users need to verify function, not only physical fit.
• Fuel application - the standard is tied to fuel oil use. That matters for burner design and procurement because it places the nozzle in the liquid-fuel burner environment.
• Classification by performance - the document characterizes the nozzles by their operational function requirements. In practice, this gives a common basis for comparing products from different suppliers.

Who uses SIST EN 293:2000?

SIST EN 293:2000 is relevant to people working on liquid-fuel burner equipment and the nozzles used in it. It is most useful when a team needs a shared test basis for nozzle selection, inspection, or product verification.

Typical users are:

• burner and nozzle designers checking whether a nozzle belongs to the covered product group
• quality teams verifying operational function against the standard’s test basis
• buyers and specifiers comparing nozzle offers on the same pressure and throughput basis
• test laboratories carrying out acceptance or conformity checks on oil pressure atomizing nozzles

What changed in SIST EN 293:2000 from the previous edition?

SIST EN 293:2000 is stated to be identical to EN 293:1992.
