Product inspection is an important work to maintain the order of market economy, according to the government's product standardization production standards, the administrative law enforcement agencies will strictly review the product quality, safety, use performance and other content. Product Inspection The detection of product quality is the key to maintain the normal economic order of the market, which plays an important role in improving national economic benefit and protecting human health.
Development significance of product inspection work
According to statistics, China's current product inspection institutions up to more than 20,000, testing content including quality, performance, function, safety, environmental protection and other fields, applicable to industry, mining, manufacturing, construction, agriculture, water and electricity industry, Product Inspection chemical industry and other industries. At the same time, the Government has introduced a number of policies to stabilize and protect market products using performance and function. After years of development, product testing has become a necessary link in the production process, all manufactured products need to strictly control their quality, Product Inspection testing whether they are safe, in line with product standards. In a broad sense, product inspection can promote the people's livelihood economy and stabilize the economic order of trade. From a narrow perspective, products in the quality of the constraints of testing, its production technology, the use of performance will continue to innovate and improve.
The role of product inspection:
1. Gatekeeper function
Check is the most basic function of product inspection, also can be called quality guarantee function. Identification is the premise of "gatekeeper", Product Inspection through the identification to determine whether the quality of products qualified. No identification can not determine the quality of the product status, it is difficult to achieve quality "check." Therefore, the identification function is the basis of the product inspection functions.
2. Preventive effects
Modern product testing is different from the traditional test of the important point, is that modern product testing is not only the role of checks, Product Inspection but also the role of prevention. The preventive effect of the test is mainly shown in the following two aspects:
(1) Preventive action through the determination of process capability and the use of control chart
(2) Preventive action through the first inspection and inspection in the process production
3. Reporting role
The function of the report is the function of feedback. This is to enable senior managers and relevant quality management departments to grasp the quality of production process in a timely manner, Product Inspection evaluate and analyze the effectiveness of the quality system. In order to make the correct quality decision and understand the change of product quality, Product Inspection we must give feedback to the management decision-making department and the relevant management department in the form of report, especially the index of calculation, in order to make correct judgment and take effective decision-making measures.
4. Improved role
Product inspection participate in quality improvement work, Product Inspection is to give full play to the quality control and preventive role of the key, but also the inspection Department to participate in the concrete embodiment of quality management.
II. Knowledge extension
1. Product Inspection:
Product inspection is a product or a number of quality characteristics of the observation, measurement, testing, and the results and the required quality requirements to compare, Product Inspection to determine the quality of each of the characteristics of an activity.
2. Product inspection methods can be classified according to different signs.
(1) to be divided into full inspection according to the quantity of inspection;
(2) According to the quality characteristic value divides into the count examination;
(3) According to the inspection technique method divides into the physical and chemical examination;
(4) The integrity of the object is classified as destructive test after inspection; nondestructive testing
(5) To be classified as a fixed test according to the place of inspection; flow inspection
(6) According to the inspection purposes: production inspection, acceptance inspection, supervision and inspection, verification inspection, arbitration inspection
(7) According to the relationship between supply and demand: first-party inspection, Product Inspection second-party inspection, third-party inspection
There are two general methods of product inspection:
1) Full inspection;
2) Sampling inspection.
According to the different characteristics and requirements of the product, product inspection methods are also different:
1 according to the Order of inspection work, there are pre-test, Product Inspection intermediate inspection and final inspection.
2 according to the inspection site is different, divided into fixed inspection and flow test.
3 According to the preventive test can be divided into the first part of the test and statistical testing.
