Overview

ISO 15835-2:2018 specifies test methods for reinforcement couplers used in mechanical splices of steel reinforcing bars. It is part of the ISO 15835 series and applies to couplers used across different standards for steel reinforcing bars and reinforced concrete design. The standard defines how to prepare test pieces, required testing equipment, measurement procedures and reporting for tensile, slip, fatigue and low‑cycle loading tests.

Key Topics

Scope and applicability: Test methods for mechanical splices of steel reinforcing bars; complements ISO 15835-1 (requirements).

Test types covered:

Tensile test - strength and ductility per ISO 15630-1; elongation measured outside the splice length.
Slip test - dual-averaging extensometer arrangement; gauge length between L + 2d and L + 6d; slip evaluation options aligned with ISO 15835-1.
High-cycle fatigue test - S–N approach and cyclic loading parameters referenced to ISO 15630-1.
Low-cycle loading test - procedure and gauge-length requirements specified for seismic/ductility verification.

Test-piece preparation: Assemble couplers exactly as installed in the field using supplier instructions; position coupler centrally on the specimen.

Measurement and instrumentation:

Use tensile testing machines and equipment conforming to ISO 15630-1.
Extensometers per ISO 9513 (class 1 or better); slip devices accurate to at least 0.01 mm.
Limit pre-load before extensometer attachment (gripping load not to exceed 10 MPa).

Geometric and environmental requirements: Minimum free lengths for tests (for example tensile test minimum free length = 400 mm + L; slip test minimum = 250 mm + L). Laboratory temperature range is recommended between 10 °C and 30 °C.

Reporting: Record failure mode/location (inside or outside mechanical splice), slip values, elongation measurements and relevant test parameters.

Applications

ISO 15835-2 is essential for:

Manufacturers of reinforcement couplers validating product performance and consistency.

Independent testing laboratories conducting qualification and routine testing.

Structural and geotechnical engineers verifying splice performance for design acceptance.

Construction quality assurance and procurement teams needing documented compliance with mechanical splice test methods. Use cases include product development, certification, acceptance testing for seismic and high‑fatigue applications, and forensic testing of spliced reinforcement.
