(i) test method: according to ansi/asqc z1.4-2003.general inspection level o take a single time. (ii) the defects classify of aql as following: major defect: aql=0.65 minor defect: aql=2.5 total defects: aql=2.5 4.1-3.nonconforming analysis ?? deal with manners a. nonconforming analysis: (i) purchaser should supply the detail dat a of non-conforming sample and the non-suitable state. (ii) after accepting the detail data from purchaser, the analysis of nonconforming should be finished in two weeks. (iii) if supplier can not finish analysis on time, must announce purchaser before two weeks. b. disposition of nonconforming: (i) if find any product defect of supplier during assembly time, supplier must change the good product for ever y defect after recognition. (ii) both supplier and customer shou ld analyze the reason and discuss the disposition of nonconformi ng when the reason of nonc onforming is not sure. 0.4 0.65 0.65 www.datasheet.co.kr datasheet pdf - http://www..net/
WD-F2440VB-EFLWB ver.4 23/26 4.1-4. agreement items both sides should discuss together when the following problems happen. a. there is any problem of standard of quality assurance, and both sides think that it must be modified. b. there is any argument item which does not record in the standard of quality assurance. c. any other special problem. 4.1-5. standard of the product appearance test a. manner of appearance test: (i) the test must be under 20w ?? 2 or 40w fluorescent light, and the distance of view must be at 30 cm. (ii) when display on use front-light test , while display off use back-light test. (iii)the test direction is base on about around 45 x of vertical line. eyes eyes 45 x 45 x (iv) definition of area: a area : viewing area. b area : out of viewing area (outside viewing area) any defect at area b could be ignored. if customer has particular requirement, this requirement should be clearly defined in inspection specification. if inspection specification has defined ot her criteria, the final judgement should follow the inspection specification . b. basic principle: (i) it will accord to the aql when the standard can not be described. (ii) the sample of the lowest accept able quality level must be discussed by both supplier and customer when any dispute happened. (iii) must add new item on time when it is necessary. c. standard of inspection:( unit: mm) lcm www.datasheet.co.kr datasheet pdf - http://www..net/
