Now from the following aspects of the management of testing instruments and equipment:
I.
The acquisition of testing instruments and equipment
(1)
The demand for the department to apply for approval by the relevant leaders.
(2)
Audit evaluation of suppliers. Generally includes:
a.
Supplier's integrity ability Supplier provides proof of qualification.
b,
Quality assurance ability of the supply zhou Research qualification certificates to gain an in-depth understanding of all aspects of the supplier.
c,
Technical performance indicators and use of products
d,
Supplier's after-sales service delivery
Establishment of the supplier's file, including: after-sales telephone contact address, etc..
(3)
The choice of instruments and equipment comparison, quality and price, not only to ensure the quality of inspection, but also affordable.
(4)
Procurement of the implementation
To determine the instrument supplier, the first with its identification of the purchase contract, after the delivery of 80% of the deposit, 20% of the amount of deduction, normal use and then pay.
II.
Check the acceptance of instruments and equipment
Instrumentation before being put into use, it must be installed to confirm, run to confirm and performance confirmation of the three steps in order to provide adequate assurance for the normal use of instruments and equipment.
(1)
Installation confirmation refers to the verification of the technical information provided by the supplier, the inspection and acceptance of the instrumentation, spare parts and the installation of the equipment to confirm whether it meets the recognized certification standards, in line with the requirements of the test of a series of activities. Generally include the following:
a, according to the ordering contract to check the arrival of the goods correctly, and registration of the instrument name, model, manufacturer's name, date of production, the instrument factory number, in the company's instrument measuring instruments number, involving the installation location, to the instrument to establish a file.
b, check the certificate of conformity of the instrument and equipment, instruction manual, maintenance manual, system software and spare parts list
c , confirm that the instrument and equipment is correctly installed, the pipeline is connected correctly, the line is installed whether the safety of applicable.
(2)
Operation confirmation refers to the standard operating procedures for stand-alone or system experiments, is to prove that the technical parameters of the equipment to meet the requirements of a series of activities. Running confirmation of the methods and limits can be based on the instrument performance specifications manual to develop the appropriate method. Confirmation, keep the original records of the test for backup.
(3)
Performance confirmation is to prove that the instrumentation system meets the design standards and accreditation guidelines and other relevant. Requirements and systematic testing. Performance confirmation is carried out with particular attention to the reliability of the tests carried out for specific applications. Stability and reproducibility of the main parameters.
Three.
Test instrumentation archives
(1)
For each instrument and equipment acceptance, the instrument and equipment will be filled with relevant information in the instrument and equipment list, and give the number, labeled in the obvious position of the instrument.
(2)
The basic contents of the instrument and equipment file are as follows: when the file is built, the name of the instrument and equipment and its software, the name of the manufacturer, contact information, after-sales service telephone number, the instrument model, the factory number, the location of the storage, the date of production, the date of the company's use, the purchase contract, the acceptance record, certificate of conformity, packing list, manuals and so on. After being put into use: plans and records of verification/calibration/verification, plans and records of maintenance, records of use, records of environmental conditions, damages, malfunctions, modifications or repairs, and scrapping sheets.
IV.
Test instrumentation state identification
Instrumentation should have a clear identification of its "test/calibration" or acceptance of the state, by the instrumentation administrator according to the test, calibration, etc., the results of the paste state identification, state identification is generally divided into the following categories
a) intact. Often green mark, indicating that the instrument is not in use.
b) To be used. Yellow marking, indicating that the instrumentation is not in use.
c) Disabled. A red flag indicating that the instrument has been damaged and is not functioning properly and needs to be repaired in a timely manner
.
In short, all the instruments and equipment in the laboratory should be marked complete, clear status, the user of the instrument
The status of the instrument at a glance, easy to manage.
V.
Check the traceability of instrumentation
All belong to the scope of mandatory testing of instruments and equipment (including other measuring instruments), should be designated by the verification/calibration of the implementation of verification. 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, but this does not mean that the test / calibration qualified test instruments and equipment in a limited period of time the accuracy always remain unchanged, on the contrary, due to the test instruments and equipment of their own drift or the impact of the environment, etc., the instruments and equipment are With its continuous use or the passage of time and change, so the period of verification can be used as an important means of verifying the credibility of the state of the instrumentation. Through the period of verification, once found to produce deviation, you can take timely measures such as repair and maintenance, as far as possible to minimize or reduce the accuracy of the test data to ensure that the inspection cycle in a timely manner, the accuracy of product quality.
Period verification should pay attention to the following aspects: (a) to determine the scope of the instrumentation during the verification. Easy to change, the drift rate is large, the environment is more stringent or more frequent use of instrumentation need to be considered for the period of verification. (b) The method of period verification, generally can refer to the instruction manual of the instrument and equipment, the instrument and equipment of the key or easy to change the technical parameters of the test, also can be used to compare the way of comparative experiments. (c) the time of the period of verification, in the middle of the two cycles of verification, can be arranged for one day to several times during the verification, when the following circumstances can also be carried out during the verification to confirm the normal state of the instrumentation samples of the results of the measurement of anomalies, the determination of doubtful data or other doubtful circumstances, (d) the period of the verification of the results of the records and processing. During the verification of the verification personnel should make a detailed record. Where the period of verification to prove that the instrumentation must be further analyzed, such as determining its performance belongs to the unqualified, the instrument malfunction, should be posted on the deactivation mark, as soon as possible on the instrument for maintenance, so as not to delay the normal use of the instrument.
VI.
The daily use of inspection instruments and equipment
(1)
Large precision instruments and equipment operators, must undergo appropriate theoretical operation training, training and qualification before being allowed to take up their duties, untrained personnel are not allowed to use at will.
(2)
Operators should be strictly in accordance with the operating procedures of the instrument and equipment, and before, during and after the use of the necessary checks and records, and should do a good job in the daily maintenance work, the use of less frequent large-scale instrumentation and equipment and electronic instruments not used for a long time, should be turned on at least once a month to check and make a good maintenance records.
(3)
The placement of instruments and equipment, the use of the environment should be in line with the provisions of the technical information instrument manual, such as instruments and equipment on the environment requirements, the room should be placed in the environmental testing, control means, and have a person or automatic recorder every day for the monitoring of the environment record.
(4)
The main instruments and equipment should have standard operating procedures.
The above six aspects of their own work in the actual work of some of the summarized work experience and feelings, there are inappropriate also request the leadership of the experts to criticize and correct.
