SIST EN 2555:2001

SIST EN 2555:2001 is a Slovenian standard published by SIST for aerospace rivets. It specifies solid rivets with a 100° normal countersunk head with dome, made from aluminium alloy 5056A, in an inch-based series, for a maximum operating temperature of 120 °C. Engineers, buyers and quality teams use it to identify the exact rivet form and material before design, sourcing and inspection.

What does SIST EN 2555:2001 specify?

SIST EN 2555:2001 specifies the characteristics of solid aerospace rivets with a 100° normal countersunk head with dome, made from aluminium alloy 5056A, in an inch-based series. The scope limits the rivets to applications with a maximum operating temperature of 120 °C, so the standard is meant for service conditions within that temperature limit.

The document is a product standard for one rivet family. The available text identifies the standard designation, title and classification fields, and states that the Slovenian standard is identical to EN 2555:1992.

What are the key requirements of SIST EN 2555:2001?

SIST EN 2555:2001 defines the rivet type, head form, material and size series together, so users can specify a precise aerospace fastener rather than a general rivet.

Product form

The standard covers solid rivets. In practice, that means the fastener is a one-piece rivet intended for permanent joints, so the user needs to match it to an assembly designed for solid riveting.

Head geometry

The rivet has a 100° normal countersunk head with dome. This matters because the joint preparation must match the head shape if the rivet is to seat correctly and achieve the intended surface profile.

Material

The rivets are made from aluminium alloy 5056A. For procurement and quality control, that fixes the material designation and helps users check compatibility with strength, corrosion and application needs.

Size series

The standard uses an inch based series. This affects drawings, part numbers and inspection because the sizing system is tied to inch-series practice rather than metric sizing.

Service temperature

The scope limits the rivets to a maximum operating temperature of 120 °C. Designers need this limit when selecting a fastener for areas exposed to heat, so the standard should be used only where the service temperature stays below that value.

What terms does SIST EN 2555:2001 define?

Solid rivets are one-piece rivets used to make permanent mechanical joints. The term tells the user to expect a non-tubular fastener that is installed by deformation.

100° normal countersunk head with dome describes the head angle and shape of the rivet. This matters because the mating part must be prepared for that geometry.

Aluminium alloy 5056A identifies the material designation used for the rivet body. Buyers and inspectors use it to specify and verify the exact alloy.

Inch based series means the standard follows an inch-oriented size system. This affects ordering, drawings and inspection records.

Maximum operating temperature 120 °C sets the highest service temperature covered by the standard. It is a practical selection limit for designers working near heat sources.

Who uses SIST EN 2555:2001?

SIST EN 2555:2001 is used in aerospace engineering, procurement and quality control for solid rivets. Design engineers use it to specify the fastener type and material on drawings. Buyers and suppliers use it to identify the correct rivet for purchasing, and inspectors use it to check that the delivered part matches the designated product family.

What changed in SIST EN 2555:2001 from the previous edition?

SIST EN 2555:2001 is identified as the Slovenian standard identical to EN 2555:1992.

What does the SIST EN 2555:2001 document contain?

The available text mainly provides the bibliographic and identification data for the standard, including its title in Slovenian, German and French, its ICS classification fields and the statement of equivalence to EN 2555:1992. It also identifies the subject as aerospace rivets in aluminium alloy 5056A. That information is useful for cataloguing, purchasing and standards searches, while the technical scope tells users exactly which rivet family the standard covers.
