In order to regulate and control the quality of the monitoring instruments and equipment procurement, to ensure the quality of the monitoring work and the performance of the contract, how to do a good job in the acceptance method of the equipment is as follows:
1 scope of application
Applicable to all levels of environmental monitoring institutions to purchase new equipment acceptance, where the allocation and the outside of the instrument may also refer to the acceptance of the provisions of this.
2 acceptance basis
On the basis of procurement acceptance instruments and services is the main purchasing contract or approved purchase requisition plan; acceptance of the relevant index of the instrument can be standard test procedures, refer to the domestic related test and analysis instrument technical requirements and methods of environmental monitoring, operational monitoring level, the future development trend and method can also fully consider the experiment the room.
3 acceptance procedures for instruments and equipment
After signing the contract for the purchase contract of the instrument and equipment, the relevant laboratory of the receiving instrument shall cooperate with the instrument and equipment manager to do the preparatory work. Acceptance into the acceptance and project acceptance, acceptance should be entered in Appendix A "equipment acceptance certificate" and "the implementation of annex B acceptance and use of information feedback equipment table, all materials of all equipment shall be filed.
3.1 acceptance refers to the acceptance by the purchase contract and equipment list of the provisions of the packing list. It includes real equipment, complete sets of parts, product certificate, instructions for use, customer service service contact card and quality assurance related technical data measurement equipment manufacturing license, verification of product approval certificate and certificate of agreement. Acceptance should pay attention to the specifications of the instrument and equipment must be in conformity with the contract provisions of the name, manufacturer and brand models, appearance intact and packing accessories complete. Acceptance time should be strictly in accordance with the provisions of the contract period, if no time limit should be in 1 months after the instrument in place, in conjunction with the supplier to a unpacking inspection and acceptance by the Laboratory Supervisor, unit equipment administrator and instrumentation personnel, self inspection and acceptance shall obtain the consent of supply units to.
3.2 project acceptance refers to the purchase of new equipment installation and commissioning, operation and implementation of the assessment and acceptance. Where (or all) for the detection and calibration of equipment, including the accuracy of detection, calibration and sampling results or significantly impact the effectiveness of the auxiliary measuring equipment (such as environmental conditions for measurement equipment), in use should be done before calibration or verification, to confirm the standard to meet the corresponding environmental monitoring method and the requirements of technical specifications.
3.3 implementation and operation in addition to the content of the assessment and acceptance of verification according to the 5.1 general technical requirements and 5.2 measurement performance index requirements, should fill in the appendix A and appendix B reporting; applicable to the blind (he controlled) examination or verification ability or external organization assessment and acceptance; typical projects or regulations project evaluation project to undertake the instrument. The new instrument has a statutory licensing authority certification, may be exempted from the requirements of 5.1 and 5.2 of the requirements of the verification.
4 acceptance method of instrument and equipment
The acceptance method mainly based on the contract agreement and the relevant national verification regulation for reference, there is no verification procedures, reference monitoring methods stipulated in the standard equipment technical requirements, administration / station instrument acceptance inspection regulations and enterprise technology requirements and analysis methods to establish the verification method. When necessary, the instrument operator can also prepare the instrument and equipment quality inspection and verification of the work instructions. Verification should be based on the national standard material or environmental samples as inspection, evaluation and source of reference, when using a calibration apparatus, standard material / environment standard sample verification can not, can be used on the way for verification, comparison method should be consistent with the provisions of the "JJF1117-2004 measuring instrument than the standard". All the results of the verification shall be filled in the related record form.
5 acceptance check
5.1 general technical indicators
5.1.1 appearance structure.
The name, usually require the instrument type, manufacturing date, serial number, measuring instruments, license number, manufacturer name and other signs should be complete and clear handwriting; appearance should not have obvious mechanical damage, scratches, concave filling and peeling; equipment the regulator should be able to adjust, the fastener without loosening the screen and the air tightness measuring instruments should be good, if there was any significant changes, with the verification / calibration certificate is valid certificate in.
5.1.2 security.
The cable connector equipment should be in good contact, equipment power supply insulation resistance between the line and the general case should not be less than 20M ohm; AC input end of the insulation strength of casing or grounding can withstand AC RMS voltage 1500V, frequency 1min 50Hz, no flashover and breakdown phenomena; average sound pressure level of equipment the normal work of the noise should be less than 80dB (A).
5.2 measurement performance index
Usually required by the instrument of the standard material / standard samples or working measuring instruments measuring accuracy (error), precision or repeatability (RSD), the correlation coefficient of the calibration curve, response time, baseline drift, span drift, sensitivity, stability and detection limits and other indicators, the focus is to check error do not exceed the maximum tolerance of use. The measurement performance of all kinds of instruments and equipment are shown in Table 1 to table 4. Equipment acceptance: as much as possible to verify some of the indicators; the use of certified reference materials / standard sample verification, verification of the indicators can be reduced as appropriate.
6 disposal of unqualified acceptance
Unqualified acceptance of the goods, shall be borne by the competent departments or persons responsible for purchasing instruments and timely contact with the supplier or manufacturer, properly resolved respectively by replacement, repair or return etc..
Note: the technology of all instruments
