If this standard is inconsistent with customer standard, it should be subject to negotiation result.本规范所制订的抽样计划，适用于本公司原材料、半成品、成品的检验接收，若此标准与客户的标准相抵触时，则依双方的约定为准；30 Responsibility 职责 Quality Assurance Dept: Completely take charge of sampling operation in accordance with the requirements of this document. 质量部：负责严格按照此文件的相关规定，进行抽样检验；40 Reference Documentation参考文件MIL-STD-105E50 Definition定义5.1 MIL-STD-105E：International approval standard of sampling, Established by US, English and Canadian three militaries association in April1963年4月投入使用,由美国,英国及加拿大三军工作組品管协会确立5.2 AQL: Acceptable quality limit， AC, RE可接受的质量水准；AC：允收， RE：拒收5.3 Lot: a collection of units of product as inspection lot检验批：作为检验对象而汇集起来的一批产品，每检验批抽样一次；5.4 The types of defects: Acceptable and bugs, refer to Acceptable Standards of IMI And Finished Good缺陷的分类：可接受和缺陷，参见来料，成品接收标准60 Operation Contents作业内容：6.1 The types of inspection objects检验品的分类 Supplementary Material: Packing box, bolt, hardware, plastic bag, label and so on 辅料：如外箱，螺钉，小五金件，胶袋，贴纸等辅助产品性材料；Main Material: Besides the supplementary material and consumes material that all raw materials主料：除辅料及耗材以外的所有原材料；Half-finished product: On the production line all has not been completed半成品：生产线上所有未完成的产品（主要指生产已组装好的成品裸机）；Finished Product: The product which have been finished all the assemblies成品：已完成所有工序要求的产品；Consume material: to assist produce, like ethyl alcohol, pickling oil, gummed paper, adhesive tape and so on ;耗材：辅助生产的消耗性材料，如酒精，防锈油，胶纸，封箱胶带等消耗型物料；6.2 Sampling Plan抽样方案The sampling plan uses MIL-STD-105E to inspect the samples by the general inspection level II single sampling plan to carry on these check in lot, details plan refer to the table as below抽样计划采用MIL-STD-105E 逐批检验抽样计划中的一般检验水平II单次抽样方案进行抽检， AQL参照下表：Types类别AQL检验水平ICIC类0.1L-IIElectrical components电子元器件0.25L-IIPlastic and hardware塑胶五金材料1.0L-IIPacking material包装材料1.5L-IIHalf/finished product半成品/成品0.4L-IIQuality Control And Sampling Plan Criteria 质量控制抽样计划作业规范DC#：HPT-QM-001-A0Revision：A0Page：3/86.3 The switching inspection procedures: normal, tightened, reduced inspection and non-inspection, if continuously 5 lots tightened inspection fails, the inspection should have been halted检验的严格性规定：分为四种，即正常检验、加严检验、放宽检验和免检；加严检验连续5批不良，则暂停检验；6.4 In inspection process no matter discover the defect, all samples must complete the inspection.在检验过程中不管是否发现缺陷，都要完成所抽样品的检验；6.5 OQC when inspect new product, rework product and product which produced at the assembly line exists major defects must start from tightened plan to carry on; specially after the formal production, under the stabilization of production, must by Manager QA agree only then changes over to the reduced inspection.OQC在检验新品、返工产品和生产有重大异常时需从加严检验方案开始进行；特别是正式生产后, 生产稳定的前提下，需由QA经理同意方可转入减量检验。6.6 Sampling plan shift rule 抽样方案转移规则6.6.1 IQC according to material number to carry on the accumulation adjustment (different supplier need to be separated statistically); OQC should carry on the accumulation and the adjustment by the different date and the different type.IQC按照待检品料号进行累积调整（不同供应商需分开统计）；OQC应以不同日期和不同机型进行累积和调整。6.6.2 According to the sampling plan, the random sampling we use, extracts the sample needs to cover the smallest unit of this lot 根据所选取的抽样方案进行随机抽样,所抽取的样品要力争最大限度的覆盖到该批产品的最小单位.6.6.3 Regarding single reduce sample inspection, if defect amounts equals or exceed the received number, but had not achieved refused number, can accept this lot. but must transfer to the normal inspection in the next lot of inspection对于单次減量抽样检查, 如果坏品数达到或超过允收数, 但未达到拒收数可接受此批, 但在下批检查中要转为正常检查.6.6.4 Regarding consumes material normal inspection continuously 5 batch of qualified, and production does not have any defect feedback, changes over to the non-inspection flow;对于耗材正常检验连续5批合格，生产无异常反馈时，转入免检流程；6.6.5 According to Sampling Plan Shift Rule Chart to operate (see appendix);按抽样方案严格度转移规则图中条件进行IQC,OQC转移抽样方案（见附件）；6.6.6 The test of finished products does not use reduce inspection, the non-inspection plan rule; 成品检验不采用放宽、免检方案规则；7.0 Appendix附件Sampling plan strict shift rule chart附件一 抽样方案严格度转移规则图Sample quantity character code table附件二 样本量字码表Normal inspection single sampling plan附件三 正常检查一次抽样方案Reduced inspection single sampling plan附件四 放宽检验一次抽样方案Tightened inspection single sampling plan附件五 加严检验一次抽样方案 附件一：抽样方案严格度转移规则图IQC进料检验转移规则：任意一批拒收或品质不稳定连续5批内有2批被拒收连续5批内有2批被拒收免检正常检验连续10批接受加严检验连续5批被接受改善OK暂停检验减量检验连续10批接受任意一批拒收OQC最终检验转移规则：任意一批拒收或品质不稳定连续5批内有2批被拒收连续5批内有2批被拒收正常检验连续3批接受加严检验连续5批被接受改善OK暂停检验减量检验 Quality Control And Sampling Plan Criteria 质量控制抽样计划作业规范Revision：A0Page：4/8Quality Control And Sampling Plan Criteria 质量控制抽样计划作业规范Revision：A0Page：5/8Appendix2 Sample quantity character code table附件二 样本量字码表Lot 批量Special Inspection Level特殊检验水平Normal Inspection Level一般检验水平S-1S-2S-3S-4IIIIII289!516252650519091150151280281500501120012013200320110 00010 00135 00035 001150 000150 001500 000500 001及以上AAAABBBBCCCCDDDAAABBBCCCDDDEEEAABBCCDDEEFFGGHAABCCDEEFGGHJJKAABCCDEFGHJKLMNABCDEFGHJKLMNPQBCDEFGHJKLMNPQR Quality Control And Sampling Plan Criteria 质量控制抽样计划作业规范Revision：A0Page：6/8Appendix 3 Normal inspection single sampling plan附件三 正常检验一次抽样方案样本量字码样本量接收质量限（AQL）0.100.150.250.400.651.01.52.54.06.5Ac ReAc ReAc ReAc ReAc ReAc ReAc ReAc ReAc ReAc ReABC2350 10 10 1DEF813200 10 10 11 21 22 31 22 33 4GHJ3250800 10 10 11 21 22 31 22 33 42 33 45 63 45 67 85 67 810 11KLM1252003150 11 21 22 31 22 33 42 33 45 63 45 67 85 67 810 117 810 1114 1510 1114 1521 2214 1521 22NPQ50080012501 22 33 42 33 45 63 45 67 85 67 810 117 810 1114 1510 1114 1521 2214 1521 2221 22R20005 67 810 1114 1521 22 -使用箭头下面的第一个抽样方案。如果样本量等于或超过批量，则执行100检验。 -使用箭头上面的第一个抽样方案。 Quality Control And Sampling Plan Criteria 质量控制抽样计划作业规范Revision：A0Page：7/8Appendix 4 Tightened inspection single sampling plan附件四 加严检验一次抽样方案样本量字码样本量接收质量限（AQL）0.100.150.250.400.651.01.52.54.06.5Ac ReAc ReAc ReAc ReAc ReAc ReAc ReAc ReAc ReAc ReABC2350 10 10 1DEF813200 10 10 11 21 22 3GHJ325080 0 10 10 11 21 22 31 22 33 42 33 45 63 45 68 9KLM1252003150 11 21 22 31 22 33 42 33 45 63 45 68 95 68 912 138 912 1318 1912 1318 19NPQ5008001250
