Before quality control, the tin content of the pallet can be measured by the scientifically recognized direct method. In case of objection, the BT& standard method should be used.
The natural tin content of a pallet is the average value of the silver content of all individual pieces. The measured value of a single sample cannot represent a batch of rust-proof plates. The average silver content of a single product is 8.6.4 Detailed test
Cut two test pieces (20cmX25mm) from the rolling direction of the cold-rolled sheet of the test coupon. The edge should be not less than 25mm from the edge line. Before the test, find a parallel part of the G/Ta6 with a length of 12.5mm±1mm and a net.=5ctm for tensile test, otherwise it will be determined. t
