What does detection mean, and what does the detection category mean

Testing is to use a specified method to test the specified technical performance indicators of an object (gas, liquid, solid). It is suitable for quality assessment in various industries, such as: civil engineering and construction engineering, water conservancy, food, chemical, environmental, machinery, machinery, etc.

What does detection mean, first explain the meaning and relationship of these three words in layman's terms:

Testing is to do experiments, do tests, and make some accurate measurements on the content and performance of certain components of the product, such as heavy metal testing, color fastness testing, flame retardant testing, etc.;

Certification, in fact, is a statement that some products meet a certain standard, and the declared documents are called certificates, such as CE certificates, RoHS certificates, etc.;

A factory audit is actually a comprehensive assessment of the factory, and if passed, a report will be issued to prove that your factory meets a common standard (such as BSCI report) or a customer's standard (such as Disney, Walmart, Target factory audit certification).

Testing and certification are for products, and factory inspection is for factories. To get the certificate, the product must be tested and the standard must be met before the certificate can be issued.

The factory has met the minimum requirements of the customer through the surface factory and is qualified to make the customer's order.

Inspection = Inspection + Testing.

Inspection is the purpose, to check whether the product meets the standard and is qualified.

Testing is a means to test product performance in a variety of ways, such as high temperature testing, combustion testing, etc.

If it is a third-party test, it is based on national standards or industry standards, combined with relevant laboratories, to carry out relevant testing.

Final confirmation of compliance with the relevant standards.

Basic Definition. inspection tests; Verification and determination. Example: Product Machine performance.

Detailed explanation. Check.

Song Shu Five Elements Zhi II": "The people of Jingyi suddenly falsely said that Ningzhou people eat people and children's ......Wang Cheng was afraid, and when he detected it, it was invisible, and the people did not lose their children, and then they knew that they were false. ”

Encyclopedia Interpretation. The specified technical performance indicators of an object (gas, liquid, solid) are tested by the specified method. It is suitable for a wide range of industries.

The first-party testing is the laboratory within the factory and the company, the second party refers to the testing institutions of national institutions, such as the Quality Supervision Bureau, and the third party refers to the private and private testing institutions.

Depending on your needs, you can test every link, raw materials, and finished products.

1.Destructive test 2Non-destructive testing.

7. Classification according to the purpose of inspection.

1.Production inspection 2Acceptance inspection 3Supervision and inspection 4Verification inspection 5Arbitration inspection is elevated.

10. Classification according to the components of the inspection system.

1.Batch by batch inspection 2Cycle inspection.

11. Classification according to the effect of the test.

1.Deterministic test 2Informative test 3Cause-finding test.

Testing: Only the test data is issued according to the sample or the inspected item, that is to say, it is only a data, which is completed by relying on the testing equipment, and there is only one test result without drawing conclusions.

Inspection: Combined with the test data or the professional judgment of the inspector, the inspection conclusion is issued. That is to say, the inspection needs to be completed by human consciousness, for example, in the motor vehicle safety inspection, there is no test data for the inspection items such as appearance and chassis, and whether the chassis is damaged is judged by the inspector to make a conclusion.

Testing is about drawing conclusions.

Detection pinyin [jiǎn cè].

Paraphrase. inspection tests; Inspection and determination: product. Machine performance.

Example. This thing needs to be further advanced with electronic equipment.

Detection depends on what you mean, whether the detection range is so light, whether it is a gas, a solid, or a water.

It shows that the test is in progress, and the test results have not yet come out. The nucleic acid test will not be released immediately, it will be temporarily stored at the nucleic acid testing point, and then sent to the laboratory to observe the results through the extraction and testing of the sample nucleostatic acid, and finally register. If the nucleic acid test shows that it is to be tested, it may not have been sent for testing after the collection has been completed or is being tested, or it may be that the test has not been registered; If the nucleic acid test shows that the test may be being carried out, but the results have not yet been released, it may also be because the barcode of some specimens cannot be scanned and identified by the laboratory in the "10-in-1" mixed collection method of large-scale population, resulting in the situation that individual tested personnel cannot find the test result or show the result as "testing".

The meaning of detection is: (moving) inspection test; Verification and determination.

Detection is the process of evaluating things by observing and measuring. Inspection is a crucial part of production and quality control to ensure that product quality meets requirements and that problems can be identified and resolved in a timely manner. This article will introduce the concept, methodology, and application of testing in detail.

The detection of lead in hail cars has a wide range of applications. In manufacturing, inspection can be used to inspect the size, shape, material, strength, etc. of a product. In the food and pharmaceutical industry, testing ensures that a product's composition and purity meet standards.

Inspection can be achieved by various means, such as visual inspection, instrumental measurements, sensory evaluation, and many more. In production and quality control, it is very important to choose the right assay method, as they will directly affect the accuracy of the test results and judgments. For example, for the dimensional inspection of some small parts, the sail digging may require the use of precision instruments such as microscopes or calipers; For food quality testing, chemical reagents or instruments may be required for analysis.

Characteristics of the testing industry

1. The testing industry is a service-oriented industry, which is manpower-intensive and knowledge-intensive. This also makes the testing industry have certain personnel and technical barriers.

2. The testing industry can grow steadily for a long time, and the industry is highly defensive.

3. The market of the testing industry has the characteristics of fragmentation, and it is a common practice for international testing and certification giants to quickly enter new areas by means of mergers and acquisitions.

4. Testing institutions will establish a significant first-mover advantage by completing the layout faster through the "opening store" model, which also makes the extension and source of good purchase a necessary means for the development of testing institutions.

5. After the multi-business and multi-network layout of the testing institution is superimposed on the continuous mergers and acquisitions to a certain stage, whether it has a high management level is the key factor that determines its sustainable development.

6. The testing business has a wide range of customers, high frequency, small amount, and excellent cash flow in the industry.

7. The intensive development momentum of inspection and testing institutions is remarkable, and the number of institutions above designated size has grown steadily.

It shows that the nucleic acid test is in progress, and the test results have not yet come out. The nucleic acid test will not be available immediately, and will be temporarily stored at the nucleic acid testing site, and then sent to the laboratory to pass the brother bridge sample 2Results are usually available within 24 hours.

The time for nucleic acid testing may be about three hours, but it depends on different regions, different medical institutions or testing centers, and the situation is different.
