Introduction

Sampling procedures for inspection specified in this standard is designed for the circulation of commodities in the field of implementation of Quality Supervision enacted. This standard is mainly used for The consumer or the relevant organization more reflect the quality of the goods, or commodity quality supervision departments at all levels of quality problems are found clues Or it is necessary to focus on the quality of the regulatory oversight of commodity sampling to detect the presence of quality of the goods (batch or overall), and by The production, operators take appropriate administrative measures to promote it to stop producing and selling substandard goods. Based on prior information under supervision understanding of this International Standard sample size sampling scheme 1. When using this standard sampling plan When committing type I error probability is extremely small, relaxed restrictions (Use probability of committing a Type II error limit USL and/or as LSL Type II error calculation reference point, β≥0.05), so that when the time supervised the overall quality level of claims is not deviated from the level of quality, it does not fail Easily found. When the sample unit sampling unqualified, there is a high probability (95%) said. "The overall supervision of the actual quality level is inferior to the provisions of Or claimed level of quality. "When the sample unit sampling qualified, show only." the sub-sampling is not found in the overall supervision of the actual quality of the water Worse than a predetermined level or alleged quality level, "it can not determine the overall supervision of qualified. Since this standard uses a sample size of only 1 program, but also so that the probability of committing Type I error is very small, so make a Type II error The probability is large, the use of this standard should not pay attention to the second category of risk control. To retest the test object, if there is evidence that there is an error the first test to the second test result is the final result; if there is no evidence Standard showed intermediate precision and reproducibility limit the difference between the first test condition error when the relevant testing standards repeatability limit has been specified, When using the method of GB/T 16306-2008 provisions to determine the final results reported in a number of tests. The end result may be a number of tests Mean results, it may be the median. In GB/T 6379.2 "measurement methods and results of Accuracy (trueness and precision) Part 2 Score. standard measurement method to determine the repeatability and reproducibility of the basic method ", GB/T 6379.3" measurement methods and results of Accuracy (trueness And precision) - Part 3. Standard Methods of measurement precision intermediate measure "how to get the specified repeatability limit, reproducibility limit and intermediate Standard deviation method under conditions of precision. As a result of this standard probability sampling plan commits the first kind of error is extremely small, so this standard specifies only sample test results objections Reinspection program. Product Quality Supervision and sampling procedures Quality information with prior case

1 Scope

This standard specifies the sampling methods in circulation in the area of \u200b\u200bquality characteristics of goods quality supervision time, sampling plan and evaluation procedures, Only for determining whether a given overall supervision does not meet certain quality requirements, it is not used to determine compliance with the overall supervision of a certain quality requirements. This standard applies to the department for supervision may endanger human health and personal and property safety of important commodities or consumer or have Reflect off tissue, insider reports, regulators found to have quality problems with prior information on the quality of the supervision of goods (bulk or separate individual) pumping Sample test. This standard does not apply to the production of internal quality control of the business, it does not apply to the acceptance of inspection of goods.
