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

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

2. Qualification Testing Program
2.1 Testing was ordered by Hilti in 2003 and conducted under the guidance of
Prof. Dr.-ing Rolf Eligehausen of the University of Stuttgart, Germany in 2003
at the Institut Für Werkstoffe Im Bauwesen and other testing laboratories.
Testing was performed according to AC193.
2.2 AC193 issued by the ICC Evaluation Service references ACI 355.2 as the
base document for the testing and evaluation protocol, adding additional ICC-
ES specific requirements as well as modifications to specific testing and
evaluation requirements. Those differences and the resulting anchor
qualification and HSL-3 design data will be the focus of this document.
2.3 For anchors to be used in facilities under the purview of the USNRC,
USNRC requirements must be met. Those requirements are summarized in
Regulatory Guide 1.199. In that guide, ACI 349-01 Appendix B Anchoring to
Concrete contains the basic design requirements for anchoring, and ACI 355.2
is an acceptable testing guide for mechanical anchors.
2.4 All submitted testing of the HSL-3 Heavy Duty Sleeve Anchor System was
performed in a satisfactory manner and submitted to ICC-ES for their review.
After considerable review, an evaluation service report (ESR) was issued, ESR
1545, which recognized compliance with AC193. The ESR specified the
appropriate design data and parameters for use with ACI 318-02, Appendix D.
2.5 Because of differences in evaluation requirements between ACI 355.2-01
and actual testing performed under AC193, this report has been prepared to
explain and comment on those differences.
