36、 From the lot take at random the number of saws shown in column 2 of table 6 relative to the appropriate lot size shown in column 1. Table 6 Sample sizes 1 2 3 Lot size Sample for inspection Sample for testing saws saws saws 10 101 251 10025050010 15 20 2 3 4 b) Sample for testing. From the sample t
37、aken in accordance with (a) above take at random the appropriate number of saws shown in column 3 of table 6. 5.2 Compliance with the specification The lot shall be deemed to comply with the requirements of the specification if after inspection and testing of the samples taken in accordance with 5.1
38、 no defective is found. 6 Inspection and methods of test 6.1 Inspection Inspect and measure each saw in the sample taken in accordance with 5.1(a) for compliance with those requirements of the specification compliance with which is not assessed by the tests given in 6.2 and 6.3. 1) This section appl
39、ies to the sampling for inspection and testing before acceptance or rejection of single lots (consignments) in cases where no information about the implementation of quality control or testing during manufacture is available to help in assessing the quality of the lot. It is also used as the procedu
40、re for adjudicating in cases of dispute. SANS 1175:2008 Edition 1.1 12 6.2 Runout test 6.2.1 Apparatus a) Bench centres and a suitable stand to accept a dial gauge that is capable of measuring to an accuracy of 0,01 mm. b) An arbor having a seating of the appropriate diameter (corresponding to the b
41、ore of the saw under test) and an integral and perpendicular shoulder of a suitable diameter, the mounting surfaces (i.e. faces of shoulder and seating) being true to within 10 m with respect to the centres of the arbor. 6.2.2 Method Rigidly mount on the arbor (in turn) each saw in the sample taken
42、in accordance with 5.1(b). Set up the dial gauge in the positions shown in figure 1, rotate the assembly slowly between centres, and check for compliance with the requirements of 3.5. 6.3 Hardness test Using the relevant procedure described in SANS 6506-1 or SANS 6507-1 and a calibrated Rockwell har
43、dness testing machine, check each saw in the sample taken in accordance with 5.1(b) for compliance with the requirements of 3.9.
