Anchor Point Testing & Certification
Anchor Point Testing, Certification & Periodic Compliance Inspection for Height Safety Systems
Fall arrest anchor testing verifies that height safety anchor points, the fixed devices workers clip into before accessing roofs, facades, and elevated structures, can actually arrest a fall when it matters. Every drilled-in fall arrest anchor installed in concrete, masonry, or rock requires proof load testing after installation and at regular intervals thereafter. AS/NZS 1891.4:2025 specifies that friction (expansion) and adhesive (chemical) anchored systems must be proof loaded as an axial pull-out force, both before initial use and during periodic inspections. For drilled-in single-person anchors, the field inspection proof load is typically applied at 50% of the design ultimate strength, which is approximately 6 kN to 7.5 kN for a 15 kN rated anchor. This field inspection proof load is distinct from the AS 5532:2025 static type test (15 kN held for 3 minutes), which is a manufacturer certification test performed before the anchor device is sold — not the periodic field inspection load.
The responsible engineer needs site evidence, not catalogue assumptions, to confirm whether the installed or proposed anchor arrangement is fit for purpose.
Why substrate testing matters for height safety
The testing requirement exists because a fall arrest anchor is only as reliable as its connection to the substrate. A 15 kN rated anchor device that has been type-tested to AS 5532:2025 in a laboratory will not deliver that capacity if the concrete it is fixed into is carbonated, cracked, or of lower strength than assumed, or if the hole was poorly drilled, inadequately cleaned, or the adhesive was not mixed or cured correctly. These are exactly the same installation variables that affect structural post-installed anchors, and they are detected by the same proof load testing methodology that ATA applies across all its programmes.
AS 5532:2025 rating levels
AS 5532:2025 replaced the 2013 edition in September 2025 and introduced four standardised rating levels: 21 kN for two-person free-fall arrest, 18 kN for two-person limited free-fall arrest, 15 kN for single-person free-fall arrest, and 12 kN for single-person limited free-fall arrest. The updated standard also introduced new test procedures for anchors with energy-absorbing properties, clarified requirements for substrate-specific testing, and mandated that two-person anchors undergo two sequential drop tests on the same device. The field inspection proof load for each rating level is derived from the design ultimate strength of the installed anchor system, not from the device rating alone. These changes mean that both the manufacturing compliance path and the field verification path are now more rigorous than under the previous edition.
ATA testing and reporting approach
ATA conducts fall arrest anchor proof load testing using the same calibrated hydraulic equipment, displacement monitoring capability, and engineer-reviewed reporting that it uses for structural anchor testing. The proof load is derived from the governing standard and applied as an axial pull-out force. The test verifies that the installed anchor sustains the nominated load without excessive movement, load decay, or visible distress to the substrate. Where failures occur, ATA documents the failure mode and load at failure to support the asset owner in determining whether the issue is isolated or systemic. Periodic inspection reports include anchor identification, test date, proof load applied, result, and any observations relevant to ongoing serviceability.
We can help confirm the proof load, sample rate, configuration, and monitoring profile before site testing is booked.

Proof Load Testing of Drilled-In Fall Arrest Anchors
Axial pull-out proof testing of expansion (friction) and adhesive (chemical) fall arrest anchors installed in concrete, masonry, and rock substrates. Field inspection proof load derived from AS/NZS 1891.4:2025, typically applied at approximately 50% of the design ultimate strength (e.g. 6–7.5 kN for a 15 kN rated single-person anchor). Note: the AS 5532:2025 static type test (15 kN / 21 kN for 3 minutes) is the manufacturer certification test — distinct from the periodic field inspection proof load.
Periodic Compliance Inspection per AS/NZS 1891.4:2025
Scheduled annual inspections at intervals not exceeding 12 months, or 6-monthly in South Australia for anchors in regular use. Anchors not in regular service must be inspected before each use. Includes visual assessment, proof load testing of drilled-in types, and documentation of anchor condition and serviceability.
Post-Installation Verification
Proof load testing of newly installed fall arrest anchors before the system is placed into service. Required by AS/NZS 1891.4:2025 for all friction and adhesive anchored systems. Confirms that the installed anchor meets the rated capacity in the actual substrate.
Substrate Assessment for Height Safety Anchors
Assessment of the substrate condition at each anchor location, concrete strength, carbonation depth, crack state, and reinforcement proximity. Substrate degradation is the primary cause of fall arrest anchor capacity reduction over time and must be evaluated during periodic inspections.
AS 5532:2025 Compliance Verification
Verification that installed anchor devices conform to the current manufacturing standard, including rated capacity marking (12 kN, 15 kN, 18 kN, or 21 kN), substrate suitability, and batch traceability. Identifies legacy anchors that may have been installed under superseded standards.
Fall Arrest System Documentation and Reporting
Comprehensive inspection and test reports suitable for building owner records, WHS compliance, and facility management systems. Reports include anchor identification, location, test results, observations, and recommendations aligned with WAHA Industry Code documentation requirements.
Multi-Anchor Programme Management
Coordinated testing programmes for buildings and facilities with large numbers of fall arrest anchors. ATA manages the test schedule, anchor register, and reporting cycle so the asset owner has a single evidence trail for ongoing WHS compliance.
Failure Investigation and Remediation Advice
When anchors fail proof testing, ATA documents the failure mode, substrate failure, bond failure, anchor device failure, and provides engineering guidance on whether remediation, replacement, or expanded testing of adjacent anchors is required.
Questions that typically come up before site testing.
How often do fall arrest anchor points need to be tested?
AS/NZS 1891.4:2025 requires permanently installed anchor points to be inspected at intervals not exceeding 12 months. South Australia is the exception — SafeWork SA mandates 6-monthly inspections for anchors in regular use (generally interpreted as more than once per month). Anchors not in regular service must be inspected before each use. Drilled-in (expansion and adhesive) anchors require proof load testing as part of the periodic inspection cycle. Additionally, any anchor that has sustained a fall arrest event, been subjected to significant loading, or where there is any doubt about the integrity of the anchor or substrate must be tested before further use.
What proof load is applied to fall arrest anchor points during periodic inspection?
There are two separate proof load levels in the height safety anchor regime and it is important not to conflate them. The AS 5532:2025 static type test — a manufacturer certification test — requires the anchor device to withstand 15 kN (single-person) or 21 kN (two-person) for 3 minutes. This is performed in a laboratory before the device is sold and is not the field inspection test. For periodic field inspections, AS/NZS 1891.4:2025 requires friction (expansion) and adhesive (chemical) anchored systems to be proof loaded, with the field inspection proof load derived from the design ultimate strength of the installed anchor system. For a standard drilled-in single-person anchor, this field inspection load is typically approximately 6 kN to 7.5 kN applied as a direct axial pull-out force — sufficient to verify the substrate bond and installation quality without permanently damaging a correctly installed anchor.
What is the difference between AS 5532 and AS/NZS 1891.4?
AS 5532:2025 is a manufacturing standard, it specifies the performance requirements, test methods, and marking requirements that anchor device manufacturers must meet before a product can be sold. AS/NZS 1891.4:2025 covers the selection, safe use, and maintenance of fall arrest systems in the field, including requirements for proof testing after installation and during periodic inspections. A fall arrest anchor must comply with AS 5532 as a product and then be installed, tested, and maintained in accordance with AS/NZS 1891.4 throughout its service life.
Do metal roof anchors (screwed to purlins) need proof load testing?
No. Metal roof anchor systems that are mechanically fixed to steel purlins or structural members do not require proof load testing. These anchors are verified through visual inspection and servicing during periodic compliance checks. Proof load testing is specifically required for drilled-in anchors, expansion (friction) and adhesive (chemical) systems installed in concrete, masonry, or rock, where the connection quality depends on the substrate condition and installation workmanship.
What are the four rating levels in AS 5532:2025?
AS 5532:2025 introduced four standardised rating levels, replacing the single 15 kN rating from the 2013 edition: 21 kN for two-person free-fall arrest, 18 kN for two-person limited free-fall arrest, 15 kN for single-person free-fall arrest, and 12 kN for single-person limited free-fall arrest. Each level has corresponding static type tests (held for 3 minutes) and dynamic drop tests (100 kg mass dropped through 2 m free fall) that the manufacturer must pass for certification. The four levels allow anchor selection to be matched more precisely to the fall protection scenario — a travel restraint or work-positioning application may only require a 12 kN rated anchor, while a full free-fall arrest system requires 15 kN (single-person) or 21 kN (two-person). The field inspection proof load applied during annual re-certification is derived from the design ultimate strength, not directly from the device rating — confirm the applicable load with the certifying engineer for your specific installation.
Who can conduct fall arrest anchor point testing?
Testing must be carried out by a competent person, someone with the training, education, and experience to assess whether the anchor complies with the relevant standards. In Queensland, inspectors should hold current public liability and professional indemnity insurance for height safety work and be trained and authorised by the relevant anchor manufacturer. ATA conducts fall arrest anchor proof load testing using calibrated hydraulic equipment and provides engineer-reviewed reporting that documents the test methodology, results, and any observations relevant to ongoing serviceability.
What does anchor certification involve and how is it different from training certification?
Anchor certification in the height safety context refers to the field verification and documentation that a specific installed anchor point meets the required load rating per AS 5532:2025 and AS/NZS 1891.4:2025. This involves proof load testing of the physical anchor, substrate assessment, and an engineer-signed report confirming the anchor is fit for service. It is separate from ATA Certified training, which is a professional development programme for installers, testers, and engineers covering anchor types, testing methodology, and specification writing. Field anchor certification is about the physical device in the building; training certification is about the competency of the person.
