Baotou steel belt, packaging tin, packaging steel strip, bluing packing belt measurement standard

Clad steel belt, packaging tin, packaging steel strip, bluing packaged with the measurement standard, generally has the following four points: 1, steel belt, packaging tin, packaging steel strip, bluing packaged with the appearance of the color and surface quality, will play steel belt, packaging tin, packaging steel strip, bluing packing belt monitored part of the platform, with a meter long ruler by baotou steel belt, packing sheet, packing the concave side of the steel belt, bluing packing belt, maximum distance measuring meter scale to the concave side. 2, steel belt, packaging tin, packaging steel strip, bluing packing belt coating thickness and thickness of the galvanized with corresponding precision measuring instruments. The site measurement should be from the edge of steel strip is not less than 3 mm, roughly equal intervals, and the length of not less than 100 mm. Is the film thickness or the thickness of the galvanized layer. 3, every batch of steel belt, packaging tin, packaging steel strip, bluing packaged with the number of test items, sampling, sampling methods and test methods should be consistent with the provisions of the state. 4, tensile test specimens shall comply with the provisions of GB/T6397 sample used without machining of rectangular cross section shape. The original cross-sectional area calculation according to the measured size.
