Measurement and testing system
Disciplinary terms
According to JJF 1112-2003 "Specification for the Recognition of Metrological Testing Systems", a metrological testing system is defined as: "a group of related or interacting legal, technical and managerial elements necessary to ensure that the metrological requirements of customers, organizations and laws and regulations are met." An effective measurement system ensures that measuring equipment and measuring processes meet the intended uses of customers, laws and regulations, and the organization's own management. Improving the measurement and testing system is a clear requirement of the General Administration of Quality Supervision, Inspection and Quarantine for the measurement work of enterprises. The goal of the measurement and testing system is to ensure that the organization has the corresponding measurement and testing capabilities, and to manage the risk of incorrect measurement results generated by the measurement equipment and measurement process, which affects the production and operation of enterprises and economic benefits.

In 2003,
International organization for Standardization
On the basis of summarizing the advanced metrology management theory and practice in the world, a new international standard ISO 10012:2003 "Measurement management system measurement process and measurement equipment requirements" has been developed, and China has converted it into a new national standard GB/ T19022-2003 /ISO 10012 in time: 2003 "Measurement management system Measurement process and measurement equipment requirements".
In order to further improve the level of measurement work of Chinese enterprises in accordance with the requirements of GB/T 19022-2003 standard and standardize the measurement and testing system confirmation work, the General Administration of Quality Supervision, Inspection and Quarantine has formulated JJF 112-2003 "Measurement and testing system Confirmation Specification" as the basis for enterprises to establish and improve the measurement and testing system. The quality management requirements of the specification cover all the requirements of Chapter 4 to Chapter 8 of GB/T 19022-2003 "Measurement Management System Requirements for Measuring Processes and measuring Equipment".
In order to ensure the continuity of China's industrial metrology work, the General Administration of Quality Supervision, Inspection and Quarantine of the State in JJF 112-2003 "Metrology testing System Confirmation Specifications" also around? GB/T 19022—2003? The implementation of the standard of "Measurement Management System Requirements for measurement processes and measuring equipment", taking into account the customary use of some metrology terms in our country, the term "measurement management system" is changed to "measurement and testing system". It is emphasized that the measurement management system of enterprises should not only "manage the risk of affecting the product quality of the organization due to the incorrect results that may be produced by the measurement equipment and measurement process", but also meet the relevant metrological legal requirements in China.
Leadership attention is the premise of improving the enterprise measurement and testing system
GB/T19022-2003 idt ISO10012:2003 "Measurement Management System Measurement process and measurement equipment requirements" (hereinafter referred to as the "new standard ") for the organization's top management and authorized managers with metrology functions in the establishment, implementation, maintenance and continuous improvement of the metrology system in the process of responsibility and authority has a new, clear provisions. This plays a great role in promoting the establishment, implementation and continuous improvement of the measurement and testing system in accordance with the new standard, and provides an organizational guarantee for the establishment, implementation and continuous improvement of the measurement and testing system.
In the process of implementing the new standard, enterprise leaders should attach great importance to measurement work, set up a measurement management committee composed of leaders of the company, workshops and relevant functional departments at all levels, strengthen the management from top to bottom, and increase the control of enterprise measurement work. The general manager and deputy general manager in charge have always participated in the decision-making of key issues in the formulation and implementation of the program, concerned about, arranged and inspected the work, often negotiated with various departments and solved the problems in the implementation process, negotiated the horizontal relationship between various departments, adhered to the publicity, implementation and rectification, and gave guarantees in terms of people, finances and materials. The leaders of all departments actively support and cooperate, and carry out the work of their departments in strict accordance with the requirements. With the attention and participation of leaders at all levels, the work of the system has been carried out smoothly.
Learning and publicity is the basis of improving the measurement and testing system of enterprises
1. Clarify the importance and necessity of improving the enterprise measurement and testing system
With the wide application of production process automation control technology and the improvement of automation control level, the dependence of production operation control on measurement is further strengthened. The realization of the automatic control of the production device weakens the operation control ability of the production device in the normal production process, so the accuracy and repeatability requirements of the measurement and control equipment are higher, and the requirements of the measurement data are also higher. This also requires enterprises to strengthen the management and effective monitoring of measuring equipment and measuring process. The establishment of the measurement testing system with data management as the core, measuring equipment management as the basis and measuring process control as the means provides a good management and control means. Therefore, improving the level of control and management is the premise of lean production, the standard to measure the level of management technology of an enterprise, and an important means to ensure high quality and low consumption, safety and environmental protection of enterprises, and to achieve good benefits and reputation.
2. Strengthen backbone training
The ISO10012 international standard is
ISO9000 family standard
In the only technical standard, according to the standard and press
AQSIQ
The measurement and testing system established by the issuance of JJF1112-2003 "Measurement and testing system confirmation Specification" is an important part of the enterprise comprehensive management system, but also an independent technical management system, in order to strengthen the understanding of the standard provisions, enterprises should send backbone personnel to participate in various standard propaganda training courses, top-down level training. The management - especially the standard certification work team must understand the content, substance and specific practices of the standard, the necessary mobilization of the operational layer, and use various opportunities to consult experts and learn from brother units... Through these studies and exchanges, gradually understand and grasp the connotation of the standard, so as to achieve the purpose of guiding the next step of work.
3. Increase publicity
Unit leaders and gaugers participate in the standard publicity mobilization meeting, explain the standards, and ask them to publicize in the unit's personnel. Publicize the standards one by one in the meeting of the control center, so that employees can gradually deepen their understanding and understanding of the standards. After the preparation of the company's "Measurement and Testing System Document", we will organize and publicize again, focusing on the management procedures formulated by the company, and list the measurement function distribution table of each department, so that each leader and backbone engaged in measurement work are clear about the content and requirements of the document. The planning and control Center also uses the blackboard newspaper and other forms of publicity, so that the new standards, norms and the company's system documents have been widely publicized in the company, laying a good foundation for the specific implementation of the next step.
Document preparation is the key to perfect enterprise measurement and testing system
The ISO10012 standard clearly requires that an effective system must be established and documented for the implementation of the standard. According to the actual situation of the company to develop a feasible document system, which is the purpose of the enterprise to establish a measurement and testing system, according to this purpose, combined with the requirements of standards and norms, the establishment of a measurement and testing system document preparation group including measurement administrators and relevant engineering and technical personnel. Because the document will be implemented in the company as a "regulation" after the formation of the document, the level of documentation is directly related to the quality of the implementation. It is the key to perfect the measurement and testing system to compile documents that meet the standard requirements and improve the entire management level through efforts. To this end, the system document should be repeatedly revised before the introduction of the relevant experts can be consulted, so that they can put forward improvement suggestions on the problems existing in the preparation of the measurement and testing system documents. The implementation of the new standard should focus on the following work:
(1) Set measurable quality goals. This is an important difference between the revised ISO 10012:2003 standard and the ISO 10012-1:1992 standard. According to the status quo of the measurement work of the unit, through identification and analysis, the general objective of the appropriate measurement and testing system should be formulated, and the relevant departments should be decomposed in accordance with the requirements of the standard and implemented at various levels.
(2) Deepen the implementation of management review and formulate clear goals and tasks. Management review is an important measure for enterprises to establish a self-improvement mechanism. The general manager personally presides over the management review, which summarizes and decides the suitability, effectiveness and adequacy of the current situation of the company's measurement and testing system, discusses, researches, verifies and analyzes the quality objectives and decomposition of the company's measurement and testing system, the determination of key measurement processes, and the measurement responsibilities of various departments. Appoint measurement management representatives to really play the role of management review.
(3) The "Measurement and Testing System Management Manual" and "Measurement and Testing System Procedure Document" have been prepared.
(4) Select and determine the key measurement processes of the Company's existing production equipment and existing product production, and evaluate the uncertainty of these key measurement processes.
(5) Revision of Measurement Calibration Method.
System is the guarantee to improve the enterprise measurement and testing system
ISO10012:2003 "management responsibilities" relative to the original standard is a new clause. Neither ISO10012-1 nor ISO10012-2 specifically lists "management responsibilities" as a separate requirement. It can be seen that international standards pay special attention to the establishment of metrological institutions, to the top leadership should attach importance to and support metrological work, and to improve the role and status of metrological functional departments.
We should seek a reasonable management mode according to the actual situation of the enterprise, considering the level of measurement work and the effectiveness of management. To this end, enterprises should further strengthen the measurement work hierarchical management responsibility system. First of all, we should clarify the status and role of the control center in the implementation of ISO10012:2003 standard process, in accordance with the requirements of the relevant provisions of the standard, combined with the specific situation of the unit to determine the positions and responsibilities of departments and personnel at all levels, and organize the implementation after approval by the general manager. The measurement work of the whole company shall be carried out according to the company, workshop (department) and centralized management. Responsibilities and authority through the form of measurement function distribution table, metrology personnel post responsibility regulations, etc., the measurement department should focus on company-level measurement, production and equipment workshops (departments) should manage and maintain all levels of material and energy metering instruments in the plant, and focus on device measurement; Each unit according to the requirements of the document, improve the measurement management network, and adopt the management method of linking the quality of measurement work with the economic assessment responsibility system, who is responsible for the measurement accident, the responsibility is clear, and the responsibility is to the person. The division of labor between the control center and other functional departments is clear, the division of responsibilities is scientific, and the unification of rights and interests ensures the smooth implementation of the measurement and testing system.
In order to improve the measurement and testing system management system, the enterprise should start from improving the work of measurement points, organize internal auditors to carry out internal audits of various departments, feedback nonconforming items to relevant departments, request rectification within a time limit, and designate internal auditors to track and verify the rectification; Through the inspection and supervision, research, guidance service process, to each department measurement work put forward guidance, and provide technical support. Through the improvement of the measurement point, the benefit of saving is obvious. At the same time, enterprises should further pay close attention to the dynamic management of the whole process of measuring equipment, formulate the dynamic management system of the whole process of measuring equipment, clarify the monitoring of the various aspects of measuring equipment from design, selection, selection, acceptance, storage, verification/calibration, use, circulation, maintenance and scrapping, and implement dynamic management of measuring equipment with microcomputer and CMMS software. Enterprise planning and control center and design, mobility, planning, procurement departments to strengthen communication, jointly good zero purchase, scrap renewal, technical transformation and other measuring equipment purchase customs, in order to ensure that the newly purchased measuring equipment has a high cost to play a positive role.
Facts have proved that enterprises to participate in market competition and intensive production, must improve the level of measurement and testing, strengthen measurement management, improve the measurement and testing system, with accurate and reliable measurement data to control production, guide management, do a good job of measurement work as the conscious pursuit of enterprises, in order to promote economic growth, so that enterprises to achieve better benefits.
According to JJG1001-1991, verification is "all the work carried out to assess the metrological characteristics of a measuring instrument and determine whether it complies with legal requirements." Calibration is "a set of operations to determine the error in the indication value of a measuring instrument under specified conditions." These two definitions are consistent with or similar to the relevant international definitions. The differences are compared in the table below
Serial number item verification calibration
1. Effectiveness is legal, government law enforcement behavior is not legal, and enterprise technology behavior
2 According to the verification regulations, there are three kinds of calibration specifications: national, regional and departmental, which can also be formulated by the relevant departments, countries, regions, departments and enterprises of the verification regulations or verification methods.
3 The content comprehensively determines the measurement characteristics, and determines the conformity only the indication error, not the conformity.
4 Certificate qualification: verification certificate (qualification level calibration certificate, error value and calibration uncertainty of the presented value) or other
Failure: Notification of verification results
5 Background legal measurement requirements, more technical measurement requirements are used under the planned economy system.
Market economy system
Lower use
6 Consider the uncertainty according to the allowable error limit prescribed by the regulation. Consider the uncertainty according to the calibration uncertainty
