GB/T19022.22000
This standard is equivalent to the international standard ISO10012-2 Quality Assurance of Measuring Equipment - Part 2: Guidelines for Measurement Process Control. The ISO10012-2 standard is the second part of the ISO10012 quality assurance of measuring equipment in the ISO9000 family of standards. The ISO9000 series of standards has been equivalent to the national standard GR/T19000-1994 series. In addition, the first part of the ISO10012 standard has also been equivalent to the national standard GB/T19022.1-1991. This standard is also equivalent to it in order to unify with it, thereby promoting the implementation of the GB/T19000 series of standards and achieving effective control of the measurement process. The general name of this standard is slightly different from that of the national standard CB/T 19022.1-1994, which is due to the insensitivity of the general names of the two original international standards that are equivalently adopted. However, this standard and the national standard GB/T19022.1-1994 still constitute two parts of the same national standard GB/19022. Most of the terms and definitions in this standard are selected from the International General Metrology Basic Terms (VIM), and the National Metrology Technical Specification of the People's Republic of China (General Metrology Terms and Definitions) (JJF1001-1998) is the latest revised national metrology technical specification by the Metrology Terminology Professional Committee of the China Institute of Metrology and Testing. In its revision, the terms and definitions in VIM are used as much as possible, which is the guiding principle of this revision. Therefore, it can be considered that VIM is adopted by JIF, and the definitions in this standard and its appendix refer to the contents in JJF. In each clause of this standard, the words in the upper left corner of the box are translated as "explanation", and are not consistent with GR/T19022.1-199-1, in order to distinguish it from the "guide" in the name of this standard. Appendix A and Appendix B of this standard are both appendices of the proposal. This standard is proposed and coordinated by the National Technical Committee for Standardization of Quality Management and Quality Assurance (CSBTS/TC151). The responsible unit for the chapter of this standard: China Standard Research Center. The participating drafting units of this standard: China Institute of Measurement and Testing, 2003 Institute of Aerospace Machinery and Electronics Group Corporation.

ISO Foreword
The International Organization for Standardization (ISO) is a worldwide federation composed of national standards bodies (ISO member bodies). The work of preparing international standards is usually done by technical committees of ISO. Each member body has the right to participate in the work of a technical committee if it is interested in the work of that committee. International organizations (official or unofficial) that maintain liaison with ISO may also participate in the work. In the field of electrotechnical standardization, ISO maintains a close cooperative relationship with the International Electrotechnical Commission (IEC). Draft international standards adopted by technical committees are submitted to member bodies for voting. They must be approved by at least 75 of the member bodies participating in the voting before they can be formally adopted as international standards. International Standard ISO10012-2 was prepared by ISO/TCI76/SC3 Technical Committee on Quality Management and Quality Assurance Supporting Technical Subcommittee. The general title of ISO10012 is quality assurance of measuring equipment, and it consists of the following parts: Part 1: Metrological confirmation system for measuring equipment Part 2: Guide to measurement process control Part 1 (under revision) has been published and is entitled Quality Assurance Requirements for Measuring Equipment - Part 1: Metrological confirmation system for measuring equipment. Annexes A and B of this standard are for reference only. GB/T19022-22000
ISO Introduction
ISO10012 is a part of the ISO9000 family of standards. This standard is intended as a guide document for quality management or as a document required by the agreement between suppliers and customers. The terms customer and supplier mentioned in the standard are broad in meaning. "Supplier" can be a manufacturer, installer or service organization. "Customer" can be a purchasing unit or user of the product. When the supplier purchases the product from a distributor or other party, it becomes a customer. The following situations recommend the use of this standard:
- When the customer specifies the required product; - When the supplier specifies the product to be provided: due to the interests of customers or members, or due to the requirements of legislative or regulatory agencies; - For the assessment and review of measurement system control. This standard is divided into two parts (in Chapter 4). For certain product specifications, the meanings of customer and supplier have been explained in this article, and all other terms should be understood according to the broad definitions given in ISO8402. In order to clearly distinguish between recommendations and instructions, the contents of the instructions are given in the box after each corresponding paragraph in Chapter 4, under the heading "Instructions". The contents of "Instructions" are for information only and do not contain requirements. Their statements do not increase, restrict or modify any requirements. Part 1 of IS(10012) contains "General quality assurance requirements for the control of measuring equipment. When statistical process control is appropriate to achieve this goal, Part 2 of IS10012 provides additional guidance on the application of statistical process control. Measurement should be considered as an integral process. The method of measurement process control is based on the regular monitoring and analysis of measurement data. It is applicable to all levels of measurement from calibration of the supplier's measurement standards by external measurement laboratories to routine measurements by the supplier. Measurement process control procedures can be used to: - detect abnormal changes in the operation of sensitive processes; - detect repeatability problems; - identify and quantify compensation or correction for any drift; - help identify predictable regular changes, including periodic changes; - provide documentation required for some quality assurance requirements. The concept of "measurement process control" is also referred to as "measurement assurance". In practice, measurement process control is particularly suitable for critical or complex measurement systems (e.g. for safety or economic purposes). Suppliers may consider that the validation system specified in 15) 10012-1 provides adequate control for routine processes, such as testing of non-critical parts. The purpose of the metrological validation system described in ISO 10012-1 is to ensure that the measuring equipment used within the validation interval is sufficiently accurate. However, the validation interval is determined based on experience. Although there is a high probability that the measuring equipment will still operate normally after the validation period, it cannot prevent accidental failure or unexpected and difficult to detect damage. In addition, the validation system cannot guarantee that the measuring equipment is used correctly. Even the most accurate measuring equipment can give inaccurate measurement results if it is used incorrectly. Correctly writing the measurement procedure is a measure but it often does not guarantee that the procedure will always be correctly executed. According to ISC 10012 Part 2, measurement is controlled as a process to reduce the possibility of problems caused by accidental failure, damage or misuse. Its effectiveness or degree depends on the frequency of verification (process control). Determining the verification rate is a matter of management and business. Therefore, this standard does not make specific (quantitative) recommendations on the verification rate. Measuring equipment is only one of many factors that affect measurement. The concept of "measurement process" is to view measurement as a complete process, from the analysis of the scientific basis of the measurement, the traceability of the measured standard value, calibration and adjustment after verification and metrological confirmation when necessary, to the measurement results given by the measuring equipment at the workplace and under the conditions of use. GH/T19022.2--2000
The operation of the metrological confirmation system usually involves sending the measuring equipment from the place of use to the central laboratory for calibration, adjustment and maintenance and verification and reconfirmation when necessary. In practice, we find that the equipment returned in this way usually does not need to be repaired or adjusted before it can operate normally. Indeed, if most equipment is not like this, then there is a high possibility of erroneous results when it is used, especially when the confirmation period is approaching. If the confirmation period of the measuring equipment expires, send it to the central laboratory for calibration, adjustment and maintenance, and verification and reconfirmation when necessary. In fact, we find that the equipment returned in this way usually does not need to be repaired or adjusted before it can operate normally. Indeed, if this is not the case for most equipment, then there is a high possibility of erroneous results when it is used, especially when the confirmation period is approaching. If the confirmation period of the measuring equipment expires, send it to the central laboratory for calibration, adjustment and maintenance, and verification and reconfirmation when necessary. Calibration is only for reconfirmation. If the measuring equipment is found to be operating normally, some people may think that the equipment can continue to be used. This will not only save a lot of money but also reduce a lot of trouble. However, we cannot accept this argument and take the risk of obtaining wrong measurement results. We believe that the combination of metrological confirmation and measurement process control can meet the needs, but it depends on cost, safety, applicability and other factors.
The concept of controlling instruments and equipment as a continuous process will be summarized in Appendix A. Appendix 100 is a bibliography.
