BS EN 1740 is a European Standard on the performance test for prefabricated reinforced components of concrete. The main aim of BS EN 1740 is to provide the best industry guidance to ensure construction materials contribute to the structural integrity of your civil engineering works.
BS EN 1740 specifies a method of determining the mechanical performances of prefabricated components made of autoclaved aerated concrete (AAC) according to prEN 12602 or lightweight aggregate concrete with open structure (LAC) according to prEN 1520, under longitudinal load which may be combined with transverse load.
These performances include:
BS EN 1740 on mechanical performances of prefabricated components of AAC or LAC is useful for:
The aggregates component is simply supported at its ends in a vertical position and loaded until collapse by a vertical line load with the required eccentricity with respect to the plane of the component, in order to determine the deflection, cracking behaviour, and the loadbearing capacity.
In this regard, BS EN 1740 specifies the apparatus requirements, as well as the measurement and conditioning of test specimens, for evaluating the mechanical performances of prefabricated AAC or LAC components.
BS EN 1740 covers the loading test on aggregate components as well as the observations and measurements made following the load test.
As a result, if you are a manufacturer of aggregate components, complying with BS EN 1740 can demonstrate the performance and credibility of your products.
