Overview

EN 15361:2007 (CEN) specifies a laboratory pull-out test method to determine how a corrosion protection coating affects the anchorage capacity of transverse anchorage bars in prefabricated reinforced components of autoclaved aerated concrete (AAC). The standard verifies whether the declared outer diameter of a coated transverse bar (φtot,g) can be used in design calculations for anchorage capacity by comparing bearing stresses for coated and uncoated conditions.

Key topics and requirements

  • Scope: Pull-out testing on prismatic AAC specimens to assess the influence of coatings on transverse bar bearing stress.
  • Test specimens: Typical specimen size 200 × 200 × 250 mm with a central longitudinal bar (φ = 7 ± 0.5 mm) and a welded transverse bar (φ = 7 ± 0.5 mm, length L = 60 mm). Three specimen types (A, B, C) are used for bond verification and comparison.
  • Measurement of coating diameter: The mean outer diameter of the coated transverse bar (φtot,m) must be measured with calipers at least six locations prior to embedding.
  • Conditioning: Specimens are conditioned to a target moisture content (6 ± 2 % by mass) and temperature (20 ± 5 °C) before testing; oven-dry reference masses are required for calculation.
  • Loading procedure: Pull-out force is applied to the longitudinal bar at a controlled rate (displacement not exceeding 0.5 mm/min) while recording load–slip curves until at least 5 mm displacement.
  • Evaluation: Bearing stress is determined from the mean force at 1 mm slip for each specimen set. The standard defines how to calculate bearing stresses for uncoated and coated bars and the coating’s influence by comparing these results.
  • Reporting: The test report must include product identification, test conditions, measured diameters, dry density and compressive strength of AAC (per EN 678 and EN 679), and the calculated bearing stresses.

Applications and users

EN 15361:2007 is practical for:

  • AAC prefabrication manufacturers assessing reinforcement detailing and coatings
  • Construction material testing laboratories performing pull-out verification
  • Structural engineers and designers validating anchorage assumptions in reinforced AAC elements
  • Certification bodies and product certifiers validating declared coated-bar diameters and performance
  • Standards committees and quality control teams implementing compliance testing

This standard supports safe and reliable use of coated transverse bars in AAC precast components by providing reproducible test methods to confirm anchorage calculations.
