EN 1337-5 is a European Standard for structural pot bearings used to support bridges and similar civil engineering structures while allowing controlled rotation and, when combined with sliding elements, movement.
It is primarily a design-and-manufacture requirements standard (not just a single bench test), and it is commonly used to guide bearing selection, factory inspection, and acceptance documentation.

EN 1337-5: Structural bearings — Pot bearings
EN 1337-5 is Part 5 of the EN 1337 structural bearings series. It focuses on pot bearings and sets requirements that manufacturers and specifiers use to define performance expectations, allowable limits, and verification activities tied to conformity and quality control.
The standard is commonly invoked on bridge projects and other heavy structures where high vertical loads and rotations must be carried reliably, with predictable behavior at the bearing interface.
Quick Definition
Standard type: Requirements standard covering design, manufacture, and verification expectations for pot bearings used as structural bearings.
Typical use: Procurement and acceptance of pot bearings for bridges and comparable supports, including documentation and inspection planning.
Key scope limits to watch: Service temperature range and limits tied to rotation and maximum elastomeric pad size can affect whether EN 1337-5 is the right reference for a specific bearing design.
What This Standard Covers
EN 1337-5 addresses functional expectations for pot bearings and provides requirements that typically span materials, design constraints, manufacturing tolerances, conformity evaluation, installation considerations, and in-service inspection topics.
It is commonly applied to fixed and sliding pot bearing configurations (with sliding behavior typically coordinated with the relevant EN 1337 sliding-element requirements where applicable).
Why This Standard Matters in Testing
Even though EN 1337-5 is not a single “test method,” it frequently drives real-world verification tasks. Project teams use it to determine what must be demonstrated through inspection, measurement, and performance checks before shipment and during acceptance.
From a lab and QA/QC perspective, the standard often influences how manufacturers validate bearing behavior under load and rotation, how critical components are checked dimensionally, and how conformity documentation is assembled for contract compliance.
Common Materials, Product Types, or Applications Covered
Common applications: Bridge bearings, viaducts, and heavy structural supports where rotation is required and where horizontal actions may be carried through the bearing system (depending on bearing configuration).
Product focus: Pot bearings used as structural bearings, including designs that may incorporate sliding interfaces and sealing elements as part of the assembly.
Practical note: Bearing configuration (fixed vs guided vs free, and whether a sliding interface is included) strongly affects what needs to be confirmed and what test/inspection fixtures are required.
Common Test or Verification Workflow
Workflows tied to EN 1337-5 typically combine engineering review with manufacturing and acceptance controls, rather than relying on one test alone.
Common verification activities: Dimensional inspection and tolerances; material and component checks; performance-oriented evaluation under representative load/rotation conditions; documentation for conformity evaluation; installation and inspection considerations for the delivered bearing.
Where testing fits: Testing is often used for design validation, type testing, and/or production verification (depending on contract requirements and the bearing’s criticality), alongside inspection and documentation controls.
Equipment Commonly Used for This Standard
Because EN 1337-5 is requirements-driven, equipment selection is usually tied to the specific verification plan (load level, rotation, movement, and what must be measured and reported).
Common equipment families: High-capacity compression/load frames or hydraulic actuators; rotation-capable bearing test rigs; displacement/rotation measurement (LVDTs, inclinometers, dial indicators, or equivalent metrology); dimensional inspection tools (CMM or precision gauges); fixtures and platens sized for full-scale bearing assemblies.
Typical lab considerations: Test capacity and platen geometry for full bearing footprint; alignment control to avoid unintended bending; instrumentation channels for force, rotation, and displacement; conditioning capability when temperature requirements are part of the verification scope.
How to Read This Designation or Revision
Designation: EN 1337-5 identifies Part 5 of the EN 1337 structural bearings series, focused on pot bearings.
Year/edition: EN standards are commonly cited with a year (for example, EN 1337-5:2005). Contracts and project specifications may also cite a national adoption (such as “BS EN 1337-5”).
Revision sensitivity: For procurement and verification planning, match your test/inspection plan to the exact edition cited in the project documents, since requirements and referenced annexes may differ between editions or national adoptions.
