Legal measurement of gastric tabletop spring plate scale production used in the Wuwei area of ​​Gansu Province, the metrological verification test institute Shen Qiu Kui Yuxia Wu Qilin National Technical Supervision Bureau Technical Supervision Bureau Volume 1988124 allows desktop spring plate seed grade accuracy scale sales and use After the announcement, the production of table spring disc scales developed rapidly. In particular, after the State Bureau of Technical Supervision proposed to limit the use of rod scales in urban fixed stalls, the table spring coil pattern was widely used in trade settlement. However, its current production and use management is not optimistic, especially in the past two years, the use of cheating patterns has been continually refurbished, seriously jeopardizing the interests of consumers. All production and use management must be highly valued by the metrology department to prevent repeated violations of the scale management.

Look at the situation of the market in our district. There are the following questions: Some desktop spring scales produced by some manufacturers do not have any anti-short measures. The parts in the scale can be adjusted and replaced at will. For example, the 101-heart spring plate produced by some enterprises in Zhejiang Province can be opened easily with a screwdriver and the back, especially the plastic cover of the front dial, without any other tools, can be removed by hand. This does not comply with the non-automatic scale general verification procedure 5.1.2.4 and the analog scale calibration procedure 3.8 for those devices that are prohibited from adjustment. Take protective measures. The part that affects the magnitude of the scale shall be sealed or sealed. The diameter of the seal area or seal shall be at least the claw. If the seal or seal is not damaged, the seal or seal may be destroyed. Provisions.

First. The number of verification divisions of table spring discs produced by some manufacturers cannot be satisfied. The requirements of the regulations, such as the production scales of the two-factory manufacturing plant in Zhejiang, are all 50. The number of divisions is the requirement that the muscles meet the minimum accuracy of 1 and 1 of the normal accuracy scale, but the general verification procedure for non-automatic scales. 42 and analog scales verification procedures 3.2, 2 notes, the number mark specifies the scale for trade settlement, the minimum number of verification scales, = 1000, for = 400. The current production of spring scales, basically for Instead of a steelyard, it is used for trade settlement, so. 1 secondary spring with a value of 5; meet the requirements of the regulations.

The first use of cheating is more serious in the production of the factory, which provides convenience for unscrupulous cheating. The two special cheating methods we found were the replacement of the dial for the twist of the yellow-hulled disk. After that, the engraved treatment is copied and attached to the spring balance of 8, so that it becomes a veritable two scales; the paper is placed on the underside of the pointer seat to make the pointer rub against the dial, and when weighing is sold , press the product or press the weighing pan by hand, the pointer can stay in any position. The real 4 restraint can be called 1.51 or even 2. When the inspection is checked, the paper is quickly taken off, then the scale is qualified. .

The countermeasure against the above question is to strengthen production management. The production history of spring-loaded spring scales is not long. It is also a matter of nearly two years to replace the scales. The licenses for manufacturing measuring instruments of several companies mentioned above were issued in 1998 and 1999. From this point of view, in the issuance of the desktop spring degree scale manufacturing license, the inspection should be strictly in accordance with the requirements of the regulations, especially the type approval and prototype test of the measuring instruments. It is necessary to fully package the spring drive mechanism dial and the pointer of the spring dial scale according to the requirements of the regulations. Specifically, like the industrial pressure, all the components of the scale are enclosed in the front and rear covers and sealed with the punching screws. . If you do not damage the seal, you can change the double-sided spring-disc scale produced by Zhejiang Zhouzhou Huachao Weighing Apparatus Co., Ltd. in the scale, as long as the front and rear covers are fixed on both sides. Secondly, it should also be based on the objective fact that the spring scale is basically used as a substitute for the bar for trade settlement.

The order is forbidden. Production of the industry's production value of 50 types should be appropriately scaled, and it is necessary to prevent the production of individual hand-workshops like steel bars. Only large-scale production can guarantee quality, and it is easy to control the production process. According to this, it is necessary to carry out inspections on the manufacture of measuring instruments for desktop spring scales. If it does not meet the requirements of the regulations, it will be rectified within a time limit. Reasonable distribution, banned the quality of the inferior quality of the scale manufacturing scales 1.4 can only prove the supervision, and only good production control, in order to make some of the scales produced in 1999 into the circulation field, the measurement department should deal with local sales The scale is checked.

For the purpose of taking some sales to suppress the scale of the milk pan, it is ordered to replace the dial with the index of 8. The index value is small. 1. The insurance can be sold after the seal is sealed. If the measures are good, just use the perforated screws to seal the seals, and use the perforated screws and lead seals to sell them. For the front cover buckles 1 to be taken with the total of 5. and the side of the back can be opened by the monthly screwdriver, sales should be prohibited, or It is modified to have anti-cheating measures and can be sold after being sealed.

First; strengthen verification management. Spring scales and levers 10. The principle of lakes. different. Play jaundice. The indirect measurement of mass by measuring the gravity acting on the spring is likely to be out of tolerance due to the difference in gravitational acceleration between the two places. Therefore, the CHINA test should be performed before the use. In addition, in the subsequent verification, that is, the periodic verification, the scales that existed in the foregoing are handled separately with reference to the sales management. If it is qualified to carry out the seal after it has passed the test, it can be used for anti-cheating ability, and it can be used continuously; if it is impossible to implement the seal, it will be eliminated.

First, strengthen the use of management. In addition to strengthening law enforcement, the metrological supervision department has severely cracked down on illegal traders. It should also be noted that the spring is a Pu'er accuracy level. According to the requirements of the retail commodity weighing measurement supervision, it can only meet the trade weighing requirements of foods, fruits and vegetables, etc., which are not higher than 6 yuan; Even if the price of other goods is higher than that of trade settlement, even people weigh 4.

A scale with a minimum division value of 1 cannot be satisfied. Because it is, 5 is allowed. error. ±8, and when the goods are weighed at a higher price, the mass is less than 2.5, and the error is allowed to be known; the allowable error between the masses greater than 2.51 and less than 10 is 10. Obviously any elastic yellow scale can meet the price of 6,000. Weighing requirements, therefore, spring scales must be prohibited from being used in these areas.

In summary, since the table spring disc scale is a scale widely used in the market trade, the number will become larger and larger, and it is necessary to strengthen management in the production and sales verification, and the various problems that appear will be eliminated in the bud. The text is for accurate and reliable metering. 1. The market calls for multi-division multi-range weighing instrument â–¡ Qingdao Weighing Test Center Cui Aiping Wang Zhenwen In recent years, whether international or domestic, the scope of legal measurement is being managed by measuring instruments. Data management and measurement of quantity are deepened. International legal measurement organization 01 empire issued international recommendations, 7 package net capacity generation 79, packaging label content.

It is a clear message reflecting this major trend of change. In this way, the expansion of the scope of legal measurement, the release of the supervision and regulation of retail goods weighing, the new requirements for the development and use of weighing instruments, and the creation of new courses.

The supervision and regulation of retail goods weighing is mainly divided into several grades according to the price and variety of the goods, which specifies the negative deviation between the commodity values ​​of different unit prices, which determines the accuracy of weighing the commodity scale. Accuracy of the metering and weighing instrument We know that the accuracy level of the non-automatic weighing instrument is determined by the verification of the absolute accuracy and the relative accuracy of the generation. The maximum number of social decisions allowed Han Qi to be equal to the verification scale value on the order of magnitude. The reality is that in a large number of business processes, in the small shops that sell high-end tea products and sell candy-like cakes, there is often only the need to scale the single-quantity single-quantity weighing. Even in large-scale integrated shopping malls, this problem is plagued to varying degrees. This is also after the promulgation of the regulations for the weighing of retail goods. The reality that China faces in weighing and measuring.

The market calls for the advent of new types of scales!

In the past, the non-automatic scales used in the market were almost all single-scale and single-range. The marketing management requires us to combine the single-segment value and the single-span process into different scales and multi-range scales. Some developed countries have quietly started. At the request of the United States, the International Legal Metrology Organization adopted the International Recommendations for non-automatic weighing instruments adopted in 1984 to add the content of the multi-division weigher Miilli, such as 1.1.14.

In the revised 1761 proposal in 1990, for the first time, there were many ranges, and the 13th factory was installed. In recent years, the electronic scales developed by China are mostly multi-scale instruments.

The definition of a multi-division scale is that there is only one measurement range, and this measurement range is divided into several parts of the partial weighing scale of the species. The range is 1. The increment or decrement is based on the loading. And automatically determined.

The multi-scale weighing instrument is divided by the sub-scale 1; 1 is different and the indexing values ​​are different. This means that there are different weighing accuracy in different weighing ranges. Therefore, the scale can be made rough and rough.

Under normal circumstances, the sale of retail goods is often inversely proportional to their price. Multi-division scale, small weighing section, small division value, high weighing accuracy; large weighing section, relatively large division value, and relatively low weighing accuracy. It just fits the above usual shopping situation.

A multi-range scale is defined as an instrument with two or more measurement ranges. On the same carrier of the scale, the maximum weighing shirt and the division value are different, and for each measurement range, it can be added from zero to its maximum weighing. At present, there are no manufacturers in China to produce multi-range scales that strictly conform to this definition. Only the type 03 electro-optical scales developed by Shanghai Weighing Apparatus Factory basically belong to the scale.

Be careful not to put more fingers. The multi-carrier scale is confused with the multi-range scale. From the definition of the multi-range scale, we can see that as long as a certain weighing value is included in different ranges, the weighing value can be accurately weighed differently. degree. That is to say, the multi-range weighing instrument solves the problem that the single-division single-range weighing instrument can only have one weighing value corresponding to the weighing accuracy. Therefore, the purchase of a multi-range weighing instrument is equivalent to the purchase of more than two. From the above analysis, it is known that the development of the multi-index multi-range weighing instrument is the retail product weighing measurement supervision regulations, and the settlement of the zero-scale retail weighing measuring instrument An important way to equip.
