ACI-349 Approval for HSL-3 Heavy-Duty Expansion Anchor

Report WC 11-02 Hilti HSL-3 Compliance September 30, 2011

3. Testing Differences among ICC-ES AC193, ACI 355.2-01,

and ACI 349-01 Requirements and Resolution of those

Differences

3.1 Testing to be performed or witnessed by an accredited

laboratory.

ACI 355.2-01 in Section 12.1states that,

“The testing and evaluation of anchors under ACI 355.2-01 shall be

performed or witnessed by an independent testing and evaluation

agency listed by a recognized accreditation service conforming to the

requirements of ISO Guides 25 and 58. In addition to these

standards, listing of the Testing and Evaluation Agency shall be

predicated on the documented experience in the testing and evaluation

of anchors according to ASTM E 488 including demonstrated

competence to perform the tests described in ACI 355.2-01.”

ACI 349-01 states in Section B3.3 that,

“Post-installed structural anchors shall be tested before use to verify

that they are capable of sustaining their design strength in cracked

concrete under seismic loads. These verification tests shall be

conducted by an independent testing agency and shall be certified

by a professional engineer with full description and details of the

testing programs, procedures, results, and conclusions.”

Test data obtained for the HSL-3 evaluation according to Annex 1, Section 5.3,

of AC193, was required to be performed in a laboratory accredited under the

requirements of ISO/IEC 17025. Further, a listing, by an accredited listing

agency, of the testing and evaluation laboratory was required to be based on

the documented experience in the testing and evaluation of anchors according

to ASTM E 488.

Resolution: Testing was performed primarily by the Institut Für Werkstoffe Im

Bauwesen. Other laboratories were also used as given in the following list,

taken from the evaluation report prepared by Prof. Eligehausen. All of the listed

laboratories were accredited by the International Laboratory Accreditation

Cooperation (ILAC) under ISO/IEC 17025. IAS, the laboratory and testing

accrediting body of the ICC, is also a member of ILAC. The European

accreditation of these testing laboratories was accepted as being competent in

the testing of anchor systems. CSTB was accredited in direct audits by IAS.
