The mechanical behaviour of the covering materials of greenhouses may be assessed by means of conventional and specific testing methods . No standard methods exist for testing the mechanical and physical properties of flexible and rigid plastics and glass to be used as covering materials of greenhou

In this paper, the most critical physical properties for the greenhouse covering materials are reviewed. The physical properties considered include the radiometric properties (transmissivity, re#ectivity and absorptivity) over several radiation bands and also the K-value (the overall heat transfer c
An indirect method for the determination of non-ionic surfactants is based on the lowering of the tensammetric peak height of ethyl acetate by competitively adsorbed surfactants. The behaviour of the tensammetric peak of ethyl acetate was examined (peak height vs. concentration of ethyl acetate and
