DIN 22252 is a German DIN standard covering round steel link chains used as traction chains in heavy-duty conveying and mining applications, including chain conveyors, bucket elevators, and winning equipment.
It is commonly referenced when specifying or verifying chain design, materials, and acceptance testing for underground mining face conveying systems where chain reliability directly impacts uptime.

DIN 22252: Round steel link chains for use in continuous conveyors and winning equipment in mining
DIN 22252 focuses on round steel link chains operating under demanding mining conveyor conditions, where chains experience high tensile loads, articulation at the chain wheel, and severe wear environments.
This is a requirements-focused standard used for procurement and quality control of chain assemblies intended for conveying and extraction equipment rather than for lifting.
Quick definition
DIN 22252 specifies requirements for round steel link chains used as traction elements in mining conveyor and winning equipment, including expectations for design, material selection, test methods, and operating forces.
What This Standard Covers
DIN 22252 is primarily used to define what a compliant round steel link chain is for mining conveyance duty.
- Chains used as traction elements in heavy-duty conveying systems (including face conveying contexts)
- Expectations tied to chain design and manufacture
- Material selection requirements and verification testing
- Testing and evaluation tied to operating/working forces for the intended application
- Application boundary: these chains are not intended to be used as load-handling devices such as slings or hoist media
Why This Standard Matters in Testing
Mining conveyor chains are high-consequence components: failures can stop production and create difficult maintenance events in constrained underground areas. DIN 22252 is used to align suppliers, buyers, and QA teams on what must be confirmed before chains enter service.
For labs and maintenance organizations, the standard is most often used as a reference for acceptance testing, audit testing, and comparison testing after repair or replacement decisions.
Common Materials, Product Types, or Applications Covered
DIN 22252 is associated with round steel link chain products used in mining material handling and extraction systems.
Common applications: Armored face conveyors and other heavy chain conveyors, bucket elevators used in mining environments, and equipment where the chain functions as the traction element.
Common system elements referenced alongside the chain: Chain connectors and scraper/flight bar components are often specified as part of the same conveying system package (the exact companion parts are typically controlled by separate documents).
Common Test or Verification Workflow
DIN 22252 is typically used within a procurement-to-commissioning workflow where the chain is validated before it is installed and put into service.
Typical workflow: (1) purchase specification and grade/size selection for the conveyor duty, (2) incoming inspection and documentation review, (3) dimensional and visual checks on links and chain lengths/strands, (4) mechanical verification tests as required by the standard and purchase contract, and (5) release for installation or corrective action if requirements are not met.
Practical caution: Chain verification often depends on the exact chain size/configuration and the way a “chain strand” is defined for the conveyor system. Matching the test setup and reporting to the cited edition and purchase specification is critical.
Equipment Commonly Used for This Standard
Because DIN 22252 includes testing requirements (without being a single “one-fixture” bench test), equipment selection is typically driven by the force levels, chain dimensions, and the specific verification items cited in the procurement documents.
Common equipment families: High-force tensile testing systems suitable for chain/strand force verification, dedicated chain grips/fixtures sized to the link geometry, dimensional inspection tools (gauges and calibrated measurement devices), and materials verification tools used for incoming QA (selected based on the required checks).
If you are sizing a machine or fixtures around maximum chain force and link geometry, you can request a detailed quote for an equipment configuration matched to your chain range and verification needs.
How to Read This Designation or Revision
DIN standards are commonly cited using the designation plus an edition date. For this document, you may see DIN 22252 cited with an edition format like “DIN 22252:2012-07”.
Revision sensitivity: Mechanical verification requirements and acceptance criteria can vary by edition. Always confirm the exact dated edition cited in the purchase specification, contract, or regulatory basis before running qualification or acceptance tests.
Related Standards, Methods, or Frameworks
DIN 22252 is commonly used alongside related documents for conveyor system components and interfaces.
- DIN 22253 (commonly cited for certain chain connector types used with chain strands)
- DIN 22257 (commonly cited for scraper/flight bar elements used with chain conveyors)
Boundary note: DIN 22252 is not a lifting/rigging chain standard; using mining conveyor chains as load-handling devices is outside the intended application scope.
