Carton, E.P. (author), Johnsen, B.B. (author), Rahbek, D.B. (author), Broos, J.P.F. (author), Snippe, A. (author)The depth of penetration (DOP) method is a well-known ballistic test method for characterisation and ranking of ceramic armour materials. The ceramic tile is bonded to a backing material of semi-infinite thickness, and the penetration depth of the projectile gives a measure of the performance of the ceramic. There is, however, an inherent...article 2019

van Hees, R.P.J. (author), Lubelli, B.A. (author), Hacuebord, A. (author)The injection of chemical products, meant to penetrate in the capillaries of the materials composingan affected wall, is perhaps the most diffused method to deal with rising damp. The majority of thesechemical products are hydrophobic treatments; they can be either solvent-based or (increasingly) water-based. Traditionally, these products are...article 2018

Valente, R. (author), de Ruijter, C. (author), Vlasveld, D. (author), van der Zwaag, S. (author), Groen, P. (author)Conductive polymer composites have been receiving increased interest both from the scientific community and industry with a special focus on electromagnetic interference (EMI) shielding applications. In this paper, we present the design, EM wave simulation, and validation through S-parameters measurements of an EMI shielding effectiveness (SE)...article 2017

de Klerk, W.P.C. (author)The surveillance of gun propellants is basically performed either by an investigation into the thermal behavior of the propellant or by the determination of its remaining effective stabilizer content. Over the years it is shown that the surveillance of NC based gun propellants is necessary. NC based materials are intrinsically unstable, and can...article 2015

Philippens, M.A.G. (author), Anctil, B. (author), Markwardt, K.C. (author)The majority of methods to assess the behind armour blunt trauma (BABT) risk for ballistic helmets is based on plastic deformable headforms. An alternative, the Ballistic Load Sensing Headform (BLSH) can record the dynamic contact force between helmet back face and the skull. Helmet BABT methods are still under development and outcomes are...conference paper 2014

de Roo, F. (author), van Beek, J.G. (author)Before the end of 2013, the responsible institutions of the European Union will probably decide on a proposal for a new “Regulation on the sound level of motor vehicles.” It will specify a new type approval test method for noise emission and will give revised limit values for the permissible noise emission per vehicle (sub-)category. The new...article 2014

Hacquebord, A. (author), Lubelli, B.A. (author), van Hees, R.P.J. (author), Nijland, T.G. (author)Rising damp is one of the most recurrent and well-known hazards to existing buildings and monuments. Several types of intervention exist to tackle the problem. Among these, the creation of a damp-proof course against capillary rise by means of injection of chemical products is one of the most diffused methods, thanks to the relatively easy and...article 2013

(author), Mangelsdorf, I. (author), Escher, S.E. (author), TNO Kwaliteit van Leven (author), KvL (author)In the FP6 European project OSIRIS, Integrated Testing Strategies (ITSs) for relevant toxicological endpoints were developed to avoid new animal testing and thus to reduce time and costs. The present paper describes the development of an ITS for repeated-dose toxicity called RepDose ITS which evaluates the conditions under which in vivo non...article 2013

Gosselink, G.A.B. (author), Anbeek, H. (author), Bijl, P. (author), Hogervorst, M.A. (author)The Triangle Orientation Discrimination (TOD) test method was applied to characterize thermal and visual range performance of the Gatekeeper Electro Optical Security System. Gatekeeper developed by Thales Nederland BV, is currently in use with the Royal Netherlands Navy. The system houses uncooled infrared and colour TV cameras providing up to...conference paper 2013

Bijl, P. (author), Hogervorst, M.A. (author)The MRTD and MRC end-to-end EO/IR system tests and corresponding models, described in NATO STANAGs 4347-4351, lead to incorrect Target Acquisition (TA) range predictions for modern imaging systems that are 1) usually under-sampled and/or 2) contain complex signal processing. Considerable efforts have been made to develop tests and models that...conference paper 2012

(author)IGUS is the International Group of Experts on the Explosion Risks of Unstable Substances. Today, the aim of the group is to exchange information on the behavior of unstable substances and to improve safety in production, storage, transport, and use of these substances. Full members of IGUS work for governments and independent research...article 2012

Weerheijm, J. (author), Vegt, I. (author)Data on the dynamic fracture energy of concrete are scarce and also not consistent due to different test methods, data analyses and definitions. In [1] the authors summarized and evaluated the test methods. Suggestions for the standardization of dynamic tensile testing were given. In the current paper the discussion is continued. First,...conference paper 2011

Bijl, P. (author), Reynolds, J.P. (author), Vos, W.K. (author), Hogervorst, M.A. (author), Fanning, J.D. (author)The TTP (Targeting Task Performance) metric, developed at NVESD, is the current standard US Army model to predict EO/IR Target Acquisition performance. This model however does not have a corresponding lab or field test to empirically assess the performance of a camera system. The TOD (Triangle Orientation Discrimination) method, developed at TNO...conference paper 2011

Krishnan, S. (author), Kerkhoff, H.G. (author), TNO Kwaliteit van Leven (author)A systematic approach to construct an effective multivariate test response model for capturing manufacturing defects in electronic products is described. The effectiveness of the model is demonstrated by its capability in reducing the number of test-points, while achieving the maximal coverage attainable by the specific test method on an...conference paper 2010
