3 Batch and sampling
3.1 Batch
Silk mouth in the same village, the same technology, the same model, the same specifications of products, each batch of 20 boxes, each containing about 30kg, or batch
10, each of about 60kg. Less than 20 cases or 10 based upon the number of calculations.
3.2 Sampling Method
Raw silk should be the subject of visual inspection, while the weight of extraction and quality testing of representative samples. Each wire cutter installed to limit pumping 1 cutter, tube
Mounted wire 1 carton limit pumping tube.
3.3 Number of samples
3.3.1 Weight test sample
3.3.1.1 twisted wire loaded 16 boxes to 20 boxes (8 ~ 10) for the number of persons, each consisting of four pumping, each twist 2 of 8 twist. Wherein the wire edge
3 pumping twist, twist the corners sauce 1, 4 Central pumping twist.
3.3.1.2 mounted wire cutter 15 cases (7) and the following batch, each batch of sauce 2 copies, each twist 2 of 4 twisted. Wherein the wire cutter edge sauce 2, in
Section 2 pumping twist.
3.3.1.3 barreled wire batch pumping 4 parts, each cylinder 1 of 4 cylinder. Wherein the wire tube, each of the lower pumping barrel 1, 2 middle pumping tube.
3.3.2 Quality inspection sample
3.3.2.1 mounted wire cutter wire from each batch of the edges, the corner twist three parts were drawn 12, 9 twisted, twisted 4 of 25 twist.
3.3.2.2 barreled wire batch extraction tube 20 from the wire box randomly.
