AbstractAn inexpensive flexural strength tester (FST) was designed and built at Plastifab Ltd. In the spirit of industrialcooperation with NRC, this tester was made commercially available to the whole Canadian Industry and one unit was evaluated by the Institute for Research in Construction. During this evaluation, significant differences were observed between results obtained with this FST unit and a Tinius-Olsen apparatus used in accordance with the ASTM test method. The initial design of the FST was therefore modified. Different modifications were tried until an improved design appeared to give satisfactory results. This design of the FST was subjected to further testing which confirmed satisfactory agreement with the ASTM test method.
