The laboratory equipment is directly used to provide test results or auxiliary tests. It is an important asset of the laboratory and an important testing tool. It plays a vital role in the accuracy and reliability of the test results. How to maintain the validity and reliability of the instrument and equipment, so that the instrument and equipment are in good condition, is particularly important in the process of product quality testing. This article summarizes how to do a good job in the management of product quality inspection instruments and equipment:
First, establish equipment and equipment files.
1. The competent department should pay attention to the establishment of the archived scope of the product quality inspection instrument materials, and set up a person to be responsible for establishing management accounts for the product quality inspection instruments.
(1), detailed registration of the instrument name, model, manufacturer name, factory number, measurement range (range), accuracy (resolution), purchase date, purchase status, purchase cost, management number, use department, operator , use, status (in use/deactivate), metrological verification cycle, metrological verification unit/department, last measurement verification date, verification result, previous measurement verification record (date and result), grade (precious, main, general), File number, etc.
(2), instrument manuals and software.
(3) Record of instrument upgrade and transformation.
(4), instrument maintenance records.
(5) Other materials produced during the use of the equipment.
2. Pay attention to the classification management of product quality inspection instruments. Due to the variety of instruments, different models, different purchase dates, calibration cycles and maintenance dates, the equipment can be divided into large, medium and small instruments, and can also be classified and managed according to the value of the instrument. The use is divided into inspection instruments, auxiliary inspection instruments, and the like.
Second, the trace value of the inspection equipment.
When the product quality inspection instrument is used for a certain period of time, in order to ensure the accuracy and traceability of the product quality inspection instrument, it is necessary to systematically organize each user department to make traceability of each test parameter to the product quality inspection instrument and test item. The measurement and uncertainty values ​​are evaluated or periodically verified for calibration. All instruments and equipment that are subject to mandatory verification shall be verified by the specified verification/calibration. After the verification/calibration is passed, the test can be used. After the verification/calibration is passed, it is only a basic measure to ensure that it is in the qualified state within the validity period of the corresponding cycle. Due to the drift of the test equipment itself or the influence of the environment, etc. The instrument set [Industrial Electrical Network-cnelc] is changed with its continuous use or time. Therefore, period verification can be used as an important means to verify the credibility of the instrument equipment. Through the period of verification, once deviations are found, maintenance and maintenance measures can be taken in time to ensure the timeliness of the inspection cycle and the accuracy of product quality.
Third, the daily use and maintenance of equipment.
Establish and improve the procedures for the use, maintenance and maintenance of instruments and equipment. The laboratory personnel must follow the requirements of the quality manual, operate the equipment and equipment to ensure the boarding, operate the specifications, carefully fill in the use records; determine the management of the equipment equipment status identification; strengthen the equipment Maintenance, repair, damage timely registration, repair and maintenance records, so that equipment and equipment in the operation process to avoid major accidents, regular maintenance, so that the equipment is in the best operating state.
The routine maintenance of equipment and equipment is a common means to ensure the stability and reliability of the instrument and equipment. Especially for large instruments and equipment, pay attention to dust, moisture, mildew and sun protection. Take effective measures to ensure that the instrument is not affected by external factors. Some instruments and equipment have strict requirements on environmental temperature fluctuations, and it is necessary to regularly check whether the constant temperature equipment is operating normally. Regularly debug the wearable parts of the instrument, lubricate the sliding and rotating parts, and inspect and tighten the loose parts. The application software is required to avoid infection. Regularly update and upgrade software and equipment to improve the service life of the instrument.
Fourth, strengthen the qualification management of equipment and equipment personnel. There are three aspects to the management of personnel:
1. Must have participated in the training of the testing equipment organized by the unit.
2. Full and detailed mastery of all aspects involved in the operation of the equipment, including the working principle, operating procedures and technical performance of the equipment.
3. Also have some knowledge of the maintenance and repair skills of the equipment. Qualification means that the operator has obtained the qualification certificate and has certain operational qualifications. Only after the approval of the agency leader can the employee actually be employed can be qualified to operate the key testing equipment.
In short, the management of equipment and equipment is an important part of the quality system of the quality inspection organization. It is a very comprehensive work, and it is also a very meticulous and cumbersome work. Only by carefully doing a good job in the management of equipment quality inspection equipment and equipment. In order to effectively grasp the normal operation of the experimental equipment.
