Options in ETAG Certifications and what they meanGABRIEL TERS B.Eng (Structural) UTS

EOTA is the European Organisation for Technical Assessment in the area of construction products. EOTA publishes ETAG’s (similar to our Australian and New Zealand Standards) for products used in the construction environment through the EU (European Union).

ETAG’s outline the requirements for the publication of ETA’s (European Technical Assessment).

An ETA is a verification document that is product specific. Manufacturers essentially use this document to quantify their product range of capabilities. An example would be pull out capacities of a particular anchor embedded to a range of depths in concrete having a range of cylinder strengths.

There are many service conditions that can affect the usage of an anchor.

Anchors in concrete, for example, are influenced by a variety of factors, including:

• Type of anchor (expansion, undercut, bonded, etc.)

• Design and material specification of the anchor (embedment depth, diameter of drill hole, cross-section of metal, strength of anchor material, etc.)

• Direction of loading of the anchor (tension, oblique tension, shear)

• Condition of concrete member (cracked, non-cracked)

• Concrete strength class

• Arrangement of anchor(s) within concrete member (distance between anchors, edge distance, etc.).

These factors above will contribute to the way a particular anchor behaves in-situ. For instance, its modes of

failure relative to the conditions it is used in. If every combination of influencing factors was tested, the results would be infinite. Thus an ETA can publish a limited number of behavioural results the manufacturer wants to verify to their customer for a specific range of applications under a limited range of conditions...This is where options come in.

EOTA allows ETA’s to offer different options for testing and verification. Options are a range of service conditions that a product is tested to. For example, Option 1 in ETAG 001 is a test regime for safety critical anchors to be used in ceilings under cracked or non-cracked conditions. Option 7, on the other hand is developed for

anchors that are to be used in a non-cracked vertical wall. ETA’s must offer at least one option for qualification.

The ETAG must show (after a test programme is completed) the expected behaviour of the product for each combination of the factors it has been tested, for the range of specific applications of its intended use.

The following table is from ETAG 001 - GUIDELINE FOR EUROPEAN TECHNICAL APPROVAL OF METAL ANCHORS FOR USE IN CONCRETE. It outlines the various options that can be chosen to be used for the determination of a specific product ETA.

The most common options you find in most published ETA’s are Option 1 (cracked and non-cracked concrete with a range of concrete strengths loaded in various directions) and Option 7 (non-cracked concrete with a range of concrete strengths loaded in various directions).

EOTA also published a separate ETAG, namely ETAG 001 – Part 6: ANCHORS FOR MULTIPLE USE FOR NON-STRUCTURAL APPLICATIONS. This ETAG is designed to take advantage of multiple anchors acting together where if one anchor slips excessively or fails the load can be transferred to other neighbouring anchors from the same group.

Table 5�3 Assessment options covered by this Guideline

*The two international methods for measuring the strength grade of concrete are cylinder and cube strength. EOTA publish both values-Example C20/25 (Concrete Cylinder/Concrete Cube). Cylinder is always stated first and is the reference used in Australian standards for concrete hardness shown in MPa. For this example C20/25-would be shown as 20MPa in Australia�

Engineering

Under each option there is a set of physical tests that must be completed to satisfy the requirements of the relevant ETAG. These tests are generally very comprehensive…and therefore quite expensive.

Not all options have to be determined

but at least one must be chosen to be published. Generally, the manufacturer will undergo a rigorous test regime to determine the results to be used for publication.

A TAB (Technical Assessment Body) defines an assessment programme

for the manufacturer (or a recognised testing facility) to determine the essential characteristics of the product. Below is a diagram of the pathways ETA’s are created.

Australian Standards have adopted ETAG 001 as AS5216 – 2018 - Design of post-installed and cast-in fastenings in concrete. The use of options is found in APPENDIX A - TESTING AND ASSESSMENT OF FASTENERS, Table A1.1.

Seismic rated anchors are metal anchors for use in concrete under seismic actions.

They are distinguished under two categories; C1 and C2. C2 is the more stringent case.

These anchors are qualified under ETAG 001 – Annex E (an option for ETAG assessment).

Tests implemented by this annex are undertaken to evaluate the performance of anchors under simulated seismic tension and shear loading, including the effects of

cracks, and under simulated seismic crack cycling conditions. (Anchors in plastic hinge zones are not addressed – and must be avoided)

Anchors must comply with ETAG 001 Part 1 to 5 for use in cracked and non-cracked concrete (Options 1 to 6) as part of the qualification in anchor seismic performance categories C1 and C2.

For anchors to qualify as C1 and/or C2 (based on ETAG 001 – Annex E requirements) they must cover the performance in the following table.

I Buildings of minor importance for public safety, e.g. agricultural buildings, etc.

II Ordinary buildings, not belonging in the other categories.

III Buildings whose seismic resistance is of importance in view of the consequences associated with a collapse, e.g. schools, assembly halls, cultural institutions etc.

IV Buildings whose integrity during earthquakes is of vital importance for civil protection, e.g. hospitals, fire stations, power plants, etc.

γ1 = importance factor (see EN 1998-1: 2004, 4.2.5); agR = reference peak ground acceleration on type A ground (see EN 1998-1: 2004, 3.2.1); S = Soil factor (see e.g. EN 1998-: 2004, 3.2.2).

3. C1 for fixing non-structural elements to structures4. C2 for fixing structural elements to structures

ETAG-001- Annex E details the methods of testing to determine the C1 and C2 performance categories.

Steel type, steel grade and production methods, head configuration, embedment depth and drilling methods are stipulated for each type of test.

The type of anchors that are covered include:

• Torque controlled expansion anchors,

• Undercut anchors (not including concrete screws),

• Concrete screws,

• Bonded anchors and

• Bonded expansion anchors

As mentioned earlier, Australian Standards have adopted AS5216 – 2018 - Design of post-installed and cast-in fastenings in concrete. A technical paper on seismic performance requirements in

Australia has been published by AEFAC (Australian Engineered Fasteners and Anchors Council). It provides a comparison and guidelines for considerations of adaption of the European and American seismic performance requirements for fastenings in the Australian seismic conditions.

Designers can calculate the seismic performance requirements of a structure (based on ground acceleration and soil factors) and

choose the appropriate category for their choice of anchors.

Annex E - Table 1.1 details the recommended use of the performance

categories C1 and C2 to the seismicity (based on ground accelerations) and building importance class. See table below.
