Tensile test GB/T 7999 Optical emission spectrometric analysis method of aluminum and aluminum alloys GB/T 8170 Rules of rounding off for numerical values & expression and judgement of limiting values 3.6 Bending property For the extruded aluminum alloy flat bars and plates with the grade of 6101, BEND the wide surfaces at an angle of 90° with the nominal thickness as bending radius. There shall be no cracks on the wide surfaces. Other requirements shall be agreed upon by the supplier and demander, and shall be indicated in the order forms (or contracts) as well. 3.7 Microstructure There shall be no over-burnt microstructures on the flat bars and plates. 3.8 Appearance quality The surfaces of the flat bars and plates shall be flat and smooth. There shall be no cracks, bubbles and corrosion spots. There shall be no fins, burrs or rips on the rounded corners.4 Test methods4.1 Chemical composition 4.1.1 The analytical method of chemical compositions shall conform to the provisions of GB/T 20975 or GB/T 7999. USE the method specified in GB/T 20975 for referee analysis. During the calculation of “Al” content, TAKE the sum of the numerical values for analysis of the conventional analytic elements and the unconventional analytic elements suspected to be excessive as the “sum of element contents”. 4.1.2 USE the comparison method of rounding values to determine the numerical values for analysis. The rules of rounding off for numerical values shall conform to the relevant provisions of GB/T 8170. The round-off digits shall be the same with the limit digits specified in GB/T 3190. 4.2 Dimensional tolerances The dimensional rounding off and measurement shall conform to the provisions of YS/T 439-2012. 4.3 Tensile mechanical properties at room temperature The method for testing the tensile mechanical properties at room temperature shall conform to the provisions of GB/T 4909.3. 4.4 Resistivity > 280 ~ 500 13 > 500 ~ 1,200 20 5.6 Determination of the inspection results 5.6.1 When the chemical compositions of any test piece are unqualified, for the product whose melting sequence can be distinguished, DETERMINE the melting sequence represented by this test piece as non-conforming. INSPECT other melting sequences in succession. DELIVER the conforming products afterwards. If the products whose melting sequences cannot be distinguished, DETERMINE this batch of products as non-conforming. 5.6.2 When the dimensional tolerance of any test piece is unqualified, DETERMINE this batch of products as non-conforming. However, it is allowed to inspect one by one. DELIVER the conforming products afterwards. 5.6.3 When the tensile mechanical properties at room temperature of any test piece is unqualified, DOUBLE the number of test pieces taken from this batch of products for retesting. If all the retesting results are qualified, DETERMINE this batch of products as conforming. If some properties of the test pieces in the retesting results are still unqualified, DETERMINE this batch of products as non-conforming. 5.6.4 When the bending property of any test piece is unqualified, DETERMINE this batch of products as non-conforming. 5.6.5 When the resistivity of any test piece is unqualified, DETERMINE this batch of products as non-conforming. 5.6.6 When the microstructure of any test piece is unqualified, DETERMINE this batch of products as non-conforming. 5.6.7 When the appearance quality of any test piece is unqualified, DETERMINE this product as non-conforming. However, it is allowed to conduct re-inspection after removing the non-conforming section. DELIVER the conforming products afterwards.6 Symbols, packaging, transportation, storage andquality certificate 6.1 Symbols 6.1.1 Product symbols ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
