EN 2553:1992

Overview

EN 2553:1992 (adopted as SIST EN 2553:2001) is a CEN aerospace series standard that defines the characteristics of solid rivets with a 100° normal countersunk head with dome, manufactured in aluminium alloy 2017A, inch-based series. The standard applies to rivets intended for aerospace applications with a maximum operating temperature of 120 °C.

This standard supports consistent procurement, interchangeability and quality control for manufacturers, assemblers and maintenance organizations working with aluminium solid rivets in aircraft structures and related assemblies.

Key Topics

• Scope and applicability: Identifies the rivet type (solid, 100° countersunk head with dome), material (aluminium alloy 2017A) and inch-based sizing series, plus the maximum operating temperature limit of 120 °C.
• Material designation: Confirms the use of aluminium alloy 2017A for the specified rivets, aligning material selection with aerospace requirements.
• Form and head style: Describes the normal 100° countersunk head form with dome that ensures a flush surface where required in aerodynamic or structural assemblies.
• Quality and interchangeability: Establishes a common reference to enable consistent dimensions, material and fit for interchangeability across suppliers and users.
• Compliance and adoption: Notes the standard is a CEN publication and has national adoptions (for example, SIST EN 2553:2001 in Slovenia).

Applications

EN 2553:1992 is focused on practical aerospace use and is relevant for:

• Aircraft primary and secondary structures where flush countersunk rivets are required for aerodynamic or structural reasons.
• Maintenance, repair and overhaul (MRO) operations requiring replacement rivets that meet original specification for fit and material.
• Suppliers and manufacturers producing inch-series solid rivets in aluminium alloy 2017A for aerospace supply chains.

Benefits include:

• Interchangeability across suppliers due to a common standard reference.
• Material consistency by specifying aluminium 2017A for predictable behavior up to 120 °C.
• Design clarity for engineers specifying countersunk rivets where flush finishing is necessary.

Related Standards

• Other aerospace rivet standards covering different head forms, materials or metric series (consult the CEN catalogue or national adoptions for exact references).
• General specifications on rivet installation, fastener inspection and quality assurance should be used in conjunction with EN 2553:1992 to ensure correct selection and application.

For procurement, design and quality assurance, reference EN 2553:1992 to ensure rivet material, head form and operating temperature suitability when specifying solid aluminium countersunk rivets in inch series for aerospace applications.
