ISO 15630-2 is an ISO test-methods standard for verifying welded fabric (welded wire reinforcement) and lattice girders used to reinforce concrete.
It focuses on chemical and mechanical testing and on measuring key geometrical characteristics for these welded reinforcement products. If you need help aligning your purchase spec or customer requirement to the right test setup and edition, you can talk with our team.
ISO 15630-2: Steel for the reinforcement and prestressing of concrete — Test methods — Part 2: Welded fabric and lattice girders
ISO 15630-2 is part of the ISO 15630 test-methods series for steels used in concrete reinforcement and prestressing applications.
This part is specifically written for welded reinforcement products (welded fabric and lattice girders) and is commonly used by manufacturers, independent labs, and QA/QC teams to support product verification and routine conformity testing.
Quick definition
Document type: Test methods.
Primary intent: Define test and measurement methods for welded reinforcement products (including mechanical testing and dimensional/geometrical checks).
Important boundary: Sampling conditions are handled by the applicable product standards rather than by this test-method document.
What this standard covers
ISO 15630-2 specifies methods used to evaluate welded fabric and lattice girders intended for reinforcing concrete. It includes methods used for chemical and mechanical assessment, along with measurement methods for geometrical characteristics relevant to these products.
For test items not addressed in this part, testing may be carried out using other parts of the ISO 15630 series (commonly Part 1) when referenced in a contract, project specification, or product standard.
Why this standard matters in testing
Welded reinforcement products combine wire/rod properties with weld integrity and product geometry. ISO 15630-2 helps labs and producers run consistent verification so results can be compared across batches, suppliers, and test locations.
From an equipment standpoint, the standard influences how you prepare and load welded product test pieces and how you document results, which in turn impacts grips/fixtures, measurement capability, and reporting workflow.
Common materials, product types, or applications covered
Product forms: Welded fabric (welded wire reinforcement) and lattice girders used for concrete reinforcement.
Common use environments: Precast concrete production, cast-in-place reinforcement supply chains, and incoming inspection where welded reinforcement products are purchased to a defined grade/product standard.
Common test or verification workflow
In typical QA/QC use, ISO 15630-2 supports a workflow that includes selecting test pieces from welded fabric or lattice girders (per the applicable product standard or agreement), preparing test pieces, running mechanical tests where required, and measuring specified geometrical characteristics.
Because welded products can require different handling than plain wire or rebar, many labs also build internal work instructions around alignment, gripping, and measurement repeatability to reduce slippage, bending, or unintended stress concentrations during loading.
Equipment commonly used for this standard
Equipment selection depends on which clauses your contract or product standard calls up, but common lab capability typically includes a calibrated universal testing machine (UTM) for the required mechanical tests and suitable fixturing to securely hold welded fabric or lattice-girder test pieces without introducing unintended bending.
Dimensional and geometrical checks typically require appropriate measurement tools (e.g., gauges and calipers) and a repeatable method for positioning the welded product during measurement.
If you are configuring a system for welded reinforcement testing (machine capacity, grips/fixtures, and measurement accessories), you can request a detailed quote matched to the product form and the specific tests you need to run.
How to read this designation or revision
Designation meaning: “ISO 15630” identifies the test-methods series for steels used for reinforcement and prestressing of concrete; “-2” indicates Part 2 for welded fabric and lattice girders.
Revision sensitivity: ISO standards are cited by year (for example, ISO 15630-2:2019). Purchase specifications and customer requirements often require results to be reported to the exact cited edition, so labs should confirm the year/edition before testing.
Related standards, methods, or frameworks
Common companion reference: ISO 15630-1 is commonly referenced for tests not specified in ISO 15630-2 when applicable to the product and when invoked by the governing product standard or agreement.
Practical note: Mechanical testing under ISO 15630-2 typically relies on general metallic-material testing and calibration practices referenced within the ISO framework, so your lab’s calibration and verification program should be aligned with the referenced requirements used in your procedure set.
