How we do NDT
CSI has a wide range of proven NDT techniques, and are award-winning specialists in the non-destructive testing and inspection industry. Our NDT services include (but are not limited to) drossbach investigation, corrosion testing, material testing, low strain impact integrity tests, pull off/shear tests, quality assurance, structural health and monitoring inspections, unreinforced masonry testing, ultrasonic testing and concrete scanning.
CSI HAS A SISTER COMPANY; CAT-D (CONSTRUCTION ANCHOR TESTING AND DRILLERS). They specialise in the following tests:
As the name suggests, ultimate tests are carried out until the ultimate strength of the fixing has been reached, and either non-elastic deformation or complete breakage has occurred. Ultimate shear and tensile tests are performed according to British Standard 8539:2012, Section B.2.3.2 – Tests for allowable resistance (statistical approach), using the procedure given in CFA Guidance note: Procedure for site testing construction fixings – 2012. A minimum of 5 shear and 5 tensile tests are performed at each location.
Proof tests are not performed to failure, but instead to a proof load, Np; a specific fraction of the rated loading. Proof tests are performed according to British Standard 8539:2012 Section 3.2 – Tests to validate the quality of installation – Proof tests. The number of fixings to be tested is dependent on the total number to be installed on the job. The standard specifies a minimum of 2.5% or at least 3 fixings per location. If the anchors hold the required load, without movement/deformation/damage to either the fixing anchors themselves or the base material into which they are loaded, they will have met the acceptance criteria. In the event of failure, the number of tests will be doubled within the discrete area of failure.
