SIST EN 14145:2004

SIST EN 14145:2004 is the Slovenian standard for holders for lifebuoys, published by SIST as an identical adoption of EN 14145:2003. It specifies the types, dimensions, materials, surface protection and designation of holders used to support lifebuoys specified in EN 14144, so it is mainly relevant for designers, manufacturers and buyers of marine safety fittings.

What does SIST EN 14145:2004 specify?

SIST EN 14145:2004 specifies holders for lifebuoys in accordance with EN 14144. The holder’s function is simple but important: it supports the lifebuoy in service.

The document is organized into six clauses:

• Scope
• Normative references
• Dimensions
• Material
• Surface protection
• Designation

In practice, that means the standard focuses on the holder as a physical item and on how to identify it correctly when ordering or making it.

What are the key requirements of SIST EN 14145:2004?

SIST EN 14145:2004 sets out the essential design, material and marking rules for lifebuoy holders. The most useful points for practical work are the dimensional rules, the allowed materials and the way the holder is designated.

• Clause 1 - Scope: The holder is for lifebuoys in accordance with EN 14144. This matters because the holder has to suit the lifebuoy it is intended to carry.

• Clause 2 - Normative references: The standard uses EN 14144 for lifebuoys and ISO 2768-1 for general tolerances. In practice, that means the holder is not specified in isolation; it has to fit the lifebuoy standard and the usual tolerance rules for dimensions.

• Clause 3 - Dimensions: The holder shall conform to the dimensions shown in Figures 1, 2 and 3, with general tolerance ISO 2768-c. The edges shall be rounded with a minimum radius of 0.3 mm, which is intended to prevent clothing from snagging. The standard also separates two forms: form A, with welded-on securing plates, and form B, for bolting on. Form B may also be fitted with a holder for a lifebuoy light.

• Clause 3 - Shape and construction: The holder does not have to look exactly like the illustration, as long as it meets the specified dimensions. This gives manufacturers some freedom in construction while keeping the functional size and mounting arrangement under control.

• Clause 4 - Material: Permitted materials are steel, hot-dip galvanized steel, stainless steel, aluminium resistant to seawater, or plastic. For specification and marking, the standard uses the abbreviations Al, Stst, St, Hgal st and Pl. This matters when choosing a material for corrosion resistance and service environment.

• Clause 5 - Surface protection: The surfaces where the lifebuoy is attached shall be plane so that chafing cannot occur. In practice, the contact area must not damage the lifebuoy during storage or use.

• Clause 6 - Designation: The designation includes the name, the standard number, the form and the material. This makes procurement and identification unambiguous, for example when ordering a specific bolted or welded holder in a defined material.

What terms does SIST EN 14145:2004 define?

SIST EN 14145:2004 uses a small set of abbreviations and form names to identify holder types and materials.

• Al - aluminium.
• Stst - stainless steel.
• St - steel.
• Hgal st - hot-dip galvanized steel.
• Pl - plastic.
• Form A - the holder made with welded-on securing plates.
• Form B - the holder for bolting on, with the option of a lifebuoy light.

Who uses SIST EN 14145:2004?

SIST EN 14145:2004 is used by manufacturers and fabricators of marine safety fittings, especially for inland navigation vessels and small craft. It is also useful for purchasers, designers and quality managers who need to specify or check holders for lifebuoys against a defined European standard.

The standard helps when selecting a construction form, choosing a material, checking edge finish and confirming that the holder matches the lifebuoy it is meant to support.

What changed in SIST EN 14145:2004 from the previous edition?

SIST EN 14145:2004 is identical to EN 14145:2003.

Which standards are used with SIST EN 14145:2004?

SIST EN 14145:2004 names two standards that support its application:

• EN 14144 - provides the requirements and tests for the lifebuoys that the holder is meant to support.
• ISO 2768-1 - provides general tolerances for linear and angular dimensions without individual tolerance indications.

What does the SIST EN 14145:2004 document contain?

SIST EN 14145:2004 contains three figures showing the securing plate, the welded-on holder form A and the bolted-on holder form B. It also gives the dimensional basis for the holder and points to ISO 2768-1 for general tolerances.

The document states the minimum edge rounding needed to reduce snagging risk and lists the permitted materials with their abbreviations. It also gives a designation example that shows how form and material are written together for ordering or specification.
