The ISO 178 standard specifies the determination of the flexural properties of plastics. In a 3-point flexure test, the specimen is placed on two parallel-positioned anvils and bent via a compression die. The specimen is not allowed to break during this process.


Calculating the flexural stress and strain typically takes into account small deflections and does not take into account any friction at the supports. For this reason, the standards limit this method to a flexural strain of 3.5%, which corresponds to a deflection of 6 mm for ISO specimens with a height of 4 mm. The calculation error accepted by the standards in this range still lies under 1% of the measured value.


Over the last decades the use of glass in the building industry has increased significantly. However, a number of challenges related to the structural use of glass still remain, such as the uncertainty of glass strength, the lack of design standards and, most importantly, the lack of an effective and durable connection method to other structural building materials such as steel (IStructE 2014).


Test procedure:Specimens are placed in the grips of a Universal Test Machine at a specified grip separation and pulled until failure. For ASTM D3039 the test speed can be determined by the material specification or time to failure (1 to 10 minutes). A typical test speed for standard test specimens is 2 mm/min (0.05 in/min). An extensometer or strain gauge is used to determine elongation and tensile modulus. Depending upon the reinforcement and type, testing in more than one orientation may be necessary. 350c69d7ab
