Foreword
GB/T 2828 "Counting Sampling Inspection Procedure" is divided into the following parts.
--- Part 1. Batch-by-batch sampling plan (ISO 2859-1.1999, IDT) retrieved by acceptance quality limit (AQL)
--- Part 2. Isolated batch inspection sampling plan by limit mass (LQ) (ISO 2859-2.1985, NEQ)
--- Part 3. Jump batch sampling procedure (ISO 2859-3.2005, IDT)
--- Part 4. Procedures for claiming quality levels (ISO 2859-4.2002, MOD)
--- Part 5. Batch-by-batch sequential sampling inspection system based on reception quality limit (AQL) (ISO 2859-5.2005, IDT)
--- Part 10. GB/T 2828 counting sampling test series of standard guidelines (ISO 2859-10.2006, MOD)
--- Part 11. Small overall claim quality assessment procedures
This part is the first part of GB/T 2828.
This part is drafted in accordance with the rules given in GB/T 1.1-2009.
This part replaces GB/T 2828.1-2003 "Counting sampling inspection procedures Part 1. Search by the acceptance quality limit (AQL)
Batch inspection sampling plan.
Compared with GB/T 2828.1-2003, the changes in technical content mainly include.
--- Terms and definitions, symbols have been modified according to GB/T 3358.2-2009. For example, change the "sampling characteristic curve" to "operational special
"The curve"; the interpretation of "defects" is defined by the term "defects" when evaluating the quality characteristics of a product or service by custom.
"defects" can be used when evaluating the quality characteristics of a product or service from a usage perspective rather than from a regulatory perspective.
This term";
--- Added a graph of Ac=4 in the average sample size curve for primary, secondary and multiple sampling in Table 9;
--- Modified some of the textual descriptions.
This part is equivalent to the international standard ISO 2859-1.1999 "Counting sampling inspection procedures Part 1. According to the acceptance quality limit (AQL)
The batch-by-batch sampling plan for the cable and the ISO 2859-1.1999 technical amendment issued by.2001-03-01. At the same time retaining GB/T 2828.1-
The following corrections to ISO 2859-1.1999 in.2003.
--- Delete the arrow in the curve of Ac=12 in Table 9;
--- In the curve of Ac = 7 in Table 9, the arrow position moved from 3 to 3.15;
--- In the curve of Ac=27, Ac=30, Ac=41, Ac=44 in Table 9, the abscissa is changed to “n×100 unit product mismatch
Number of grids/100".
