Study on the Measurement of the Net Content of Quantitative Packaging Commodities

Quantitative packaging commodity net content measurement inspection work to study the legitimate rights and interests of consumers, to foster the healthy development of the socialist market economy, China issued the "Quantitative Packaging Commodity Measurement Supervision Regulations" in 1995. In the past few years, a lot of work has been done in accordance with the regulations of the local quality and technical supervision departments. Although it has a certain role, it has little social impact, poor supervision and lack of scientificity. It has caused passive measurement of quantitative packaging commodity measurement. On the basis of summing up the lessons learned, the state issued JJF1070-2000 "Quantitative Packaging Commodity Net Content Measurement Inspection Rules" (hereinafter referred to as the rules). The promulgation of this "rule" has aroused great attention from all walks of life. Especially in our quality and technology supervision and inspection institutions, it is considered that the supervision and inspection of the net content of quantitative packaging goods is no longer in the form of general street inspection labels. It is to include this work in scientific and data-based. Not only has a reliable technical guarantee for consumers, but also plays a very positive role in promoting the qualified rate of quantitative packaging products for quantitative packaging production and sales enterprises.

The basic idea of ​​the implementation test of quantitative packaging commodity supervision and inspection is that, according to the mathematical statistics theory, for a certain inspection batch, a certain amount of commodities are randomly selected from the batch to form a sample under a certain confidence level, and the sample is inspected. Then, based on the test results of the Lu Zhanhai sample, it is inferred whether the inspection lot is qualified.

The available block diagram port simply indicates: the result of this test determines that the batch quality is in the sales process, and the products are relatively scattered. The inspection organization should take samples in strict accordance with the sampling plan and conduct inspection. For the formation of batches, stratified sampling should be used to ensure the maximum representativeness and randomness of the samples. Only in this way can we more accurately control the risks of producers and users, in order to fully and effectively play the role of quality and technical supervision.

2. Implementation of supervision and inspection of quantitative packaging products For quantitative packaging production enterprises, they should be strictly in accordance with the requirements of the “Evaluation Standards for Measurement Assurance Ability of Quantitative Packaging Commodity Manufacturing Enterprises”, and equipped with measuring equipment whose measurement characteristics meet the specified requirements. The maximum allowable error of the measuring instrument equipped by the enterprise for measuring the net content of the packaged goods shall be less than or equal to one third of the negative deviation of the measured packaged goods. In the packaging equipment and packaging process, the metering rate of the measuring instruments used for the quantity inspection of the goods must reach 100%. All equipment should be periodically verified or calibrated. However, it was found in the work that there are three situations in quantitative packaging production enterprises. The first is workshop-style empirical control; the second is controlled by measuring instruments; the third is automatic control. Most of the metering equipment used by these companies is not subject to periodic verification or calibration. The ability of quantitative packaging measurement control is poor, which seriously restricts the development of enterprises. In order to serve the enterprise, we should first use the method of post-service inspection to first organize and calibrate the personnel of the calibration organization, conduct consultations on the enterprise, help the enterprise to prepare a list of measuring instruments, and implement regular verification or calibration. For those companies that do not undergo rectification, mandatory sampling inspections should be implemented. Manufacturers should use isometric sampling methods or stratified sampling methods in warehouses.

Penalties for unqualified inspections and exposure to the society. To achieve quantitative packaging measurement behavior of the company's implementation specifications.

The measurement behavior of the packaging manufacturing enterprises to ensure the legitimate interests of enterprises and consumers. The purpose of our inspection work is also here.
