What does traceability mean?

Question 1: The meaning of traceability is the vocabulary of measurement. In common parlance:

How to prove the accuracy of measuring products? It can be compared with measuring equipment with higher accuracy. However, how can a higher precision measuring device prove to be accurate? Compared with the measuring device with higher accuracy.

In this way, it is compared to the highest standard-national measurement standard or international measurement standard.

This is the process of measuring and measuring product traceability. Measuring and measuring the traceability of products means that they can be traced back to the highest standards through the above methods.

Question 2: What is the traceability of instruments and equipment? Traceability judgment: the characteristics of measurement results or standard values. Representing this value can indicate its relationship with a (usually national or international) reference standard through an uninterrupted comparison chain with specified uncertainty.

Traceability of measuring instruments and equipment In order to ensure the accuracy and reliability of measuring instruments and equipment, the values are traced back to national or international standards. Corresponding to traceability is transmission, which is from top to bottom and traceability is from bottom to top. It can also be popularly understood as the calibration and metrological verification of instruments and equipment.

Question 3: Where is Taohuayuan Community in Qingdao Information Port? As long as you are from Qingdao, there are all kinds of games and movies, which are of course free.

Question 4: What is retroactivity? This uninterrupted comparison chain is also called "traceability chain". Traceability is called traceability or traceability in ISO9000 family standards, and its meaning is very wide. In the field of laboratory accreditation and measurement, traceability reflects a characteristic of measurement results or measurement standards, that is, the values of any measurement results and measurement standards must ultimately be linked with national or international measurement standards to ensure the unity of measurement units and the accuracy, reliability, comparability, repeatability and reproducibility of the values. And its way is to trace back to the source of measurement (measurement benchmark) according to this comparison chain. Traceability is a term widely used in the field of international metrology. As far as its technical content is concerned, it is similar to the commonly used term "value transfer" in China, and the traceability system formed by uninterrupted comparison chain is similar to "verification system" However, there are great differences in management methods. The traceability of measured values is from bottom to top. According to the requirements of measurement accuracy, enterprises can independently find reference standards with good uncertainty to calibrate measuring equipment, and even compare or calibrate them with national or international measurement standards across regions and borders, so as to reasonably meet the use requirements. The value transfer is from top to bottom, especially for the compulsory verification of measuring instruments, which will inevitably lead to the repeated setting of measuring and verification institutions and the increase of transfer links, thus losing part of the measurement accuracy. In order to be in line with international practice and meet the needs of the development of socialist market economy, we should advocate the traceability of quantity.

Question 5: What does organic traceability mean? Organic and traceable are two words. The former refers to organic food, that is, products that have passed CQC (China Quality Certification Center) testing and organic certification, and passed the inspection and certification, and issued organic food certificates.

Traceability refers to a series of processes of products from raw materials-planting-processing-production-finished products-warehousing-logistics-distributors-end consumers, which are displayed in the form of two-dimensional codes through technical means such as the Internet of Things and big data. Now it is generally traced by QR code. To put it simply, it is to identify each commodity with an item code, which is equivalent to making an ID card for each commodity, and it is unique and different.

One is to play the role of counterfeiting, and the other is to trace the situation of products in all links and effectively control product quality problems.

Organic traceability is equivalent to tracing the source of organic food.

Question 6: What does it mean to measure the traceability of products? Traceability is a professional vocabulary of measurement, and measurement originally belongs to the field of measurement.

The answer upstairs is very professional. In common parlance:

How to prove the accuracy of measuring products? It can be compared with measuring equipment with higher accuracy.

However, how can a higher precision measuring device prove to be accurate? Compared with the measuring device with higher accuracy.

In this way, it is compared to the highest standard-national measurement standard or international measurement standard.

This is the process of measuring product traceability, which means that the measured product can be traced back to the highest standard in the above way.
