The tensile strength, yield strength and percentage elongation after fracture of Powerway solar mounting system all surpassed standard levels.
Powerway mounting system passed the tension test, coating sickness, chemical composition analysis, bend test and fire classification of SGS. Those tests were taken under standards of many countries.
The tensile strength, yield strength and percentage elongation after fracture of Powerway all surpassed standard levels.
Tensile strength is indicated by the maxima of a stress-strain curve and, in general, indicates when necking will occur. As it is an intensive property, its value does not depend on the size of the test specimen. It is, however, dependent on the preparation of the specimen and the temperature of the test environment and material. The standard way to measure tensile strength is to use a small bar with uniform width (apart from at the edges where the thickness increases) and to 'pull' at each end until the bar fails.
The yield strength of a material is defined in engineering and materials science as the stress at which a material begins to deform plastically. Prior to the yield point the material will deform elastically and will return to its original shape when the applied stress is removed. Once the yield point is passed some fraction of the deformation will be permanent and non-reversible.
