[Introduction]? How to maintain the effectiveness and reliability of the instrumentation, so that the instrumentation is in perfect condition, in the process of product quality testing is particularly important. This article on how to do a good job of product quality inspection instruments and equipment management to discuss the following points.
Laboratory instruments and equipment are directly used to provide test results or to assist in testing, is an important asset of the laboratory, but also an important testing tool. The accuracy and reliability of the test results play a vital role. How to maintain the effectiveness and reliability of the instrumentation, so that the instrumentation is in good condition, in the process of product quality testing is particularly important. In this paper, how to do a good job in the management of product quality inspection instruments and equipment to discuss the following points.
One is the establishment of instrumentation files. The competent department should focus on the establishment of product quality inspection instrument material archiving range, and set up a person responsible for the establishment of product quality inspection instrument management accounts. (1) detailed registration of the instrument name, model, manufacturer's name, factory number, measurement range (range), accuracy (resolution), date of purchase, purchase status, purchase cost, management number, the use of the department, operator, use, status (in use / out of service), measurement and calibration cycle, measurement and calibration unit / department, the last measurement and calibration date, calibration results, the previous measurement and calibration records (date and results), grade (date and results), and the quality of the instrument. ), grade (valuable, major, general), file number. (2) Instrument manuals and software. (3) Instrument upgrading records. (4) Instrument maintenance records. (5) Other materials generated during the use of instruments and equipment.
Focus on product quality inspection instruments for classification and management. Due to the variety of instruments, different models, different purchase date, calibration cycle and maintenance date is also different, so the instrumentation can be divided into large, medium and small instruments, can also be classified according to the value of the instrument management, and from the use of the instrument is divided into the inspection instrument, auxiliary inspection instrument, etc..
The second is the measurement value of inspection instruments and equipment traceability. When the use of product quality inspection equipment to a certain period, in order to ensure the accuracy of product quality inspection equipment and traceability of the value, to systematically organize the use of various departments of product quality inspection equipment, testing projects to make the traceability of the testing parameters of the measurement and uncertainty of the value of the assessment or periodic calibration to be calibrated. All instruments and equipment belonging to the scope of mandatory calibration, should be designated by the verification / calibration of the implementation of calibration. Test / calibration qualified before experimental use, test / calibration qualified, just to ensure that it is in the corresponding cycle of the validity of the period in a qualified state of a basic measure, due to the drift of the test instruments and equipment itself or the impact of the environment, etc., the instrumentation is with the continuous use of its time or the passage of time and change, therefore, can be used as a verification of the state of the instrumentation credibility of the period verification Therefore, period verification can be adopted as an important means to verify the reliability of instrument status. Through the period of verification, once found to produce deviation, can be taken in a timely manner to repair and maintenance measures to ensure the timeliness of the inspection cycle and the accuracy of product quality.
Third is the daily use and maintenance of instruments and equipment. The establishment of a perfect instrumentation use, maintenance, repair procedures, laboratory personnel must be in accordance with the requirements of the quality manual, the operation of instrumentation to achieve licensed, standardized operation, and carefully fill out the use of records; to determine the state of the instrumentation labeling management; to strengthen the maintenance of instrumentation, repair, damage to the timely registration, repair and maintenance records, so that the instrumentation in the process of operation to avoid major accidents, regular maintenance
Instrumentation and equipment in the best operating condition.
The routine maintenance of the instrumentation is to ensure that the instrumentation is stable, reliable and common means. Especially for large instruments and equipment to pay attention to dust, moisture, mold, sun. To take appropriate and effective measures to ensure that the instrument is not affected by external factors and damage. Some instruments and equipment on the environmental temperature fluctuations have more stringent requirements, to regularly check whether the thermostat equipment is operating normally. Regularly debug the easy-to-wear parts of the instrument and equipment, lubricate the sliding and rotating parts, and check and fasten the easy-to-loosen parts. The application software is required to avoid virus infection. Regularly update and upgrade the software of the instrument and equipment to improve the service life of the instrument.
Fourth is to strengthen the qualification management of the personnel using the instruments and equipment. The management of personnel involved in three aspects: first, must have participated in the organization of the unit testing equipment use training; second, the operation of the equipment involved in all aspects of the equipment, including the working principle, operating procedures, technical performance, etc., to have a comprehensive and detailed mastery; and finally, the maintenance of the equipment in the maintenance of knowledge and skills should also be understood. Qualified refers to the operator has obtained the calibration qualification certificate, with a certain operating qualifications, the only by the leadership of the organization's approval can be truly realized on duty, can be qualified to operate the key testing equipment.
In short, the instrumentation management is an important part of the quality inspection agency quality system, is a very comprehensive work, but also very detailed and tedious work, only to do a good job of product quality inspection instrumentation management of each job, in order to effectively grasp the normal operation of the experimental equipment.
