Micro-nano analysis of how to do a good job measuring equipment measurement results (a)



Before using the measuring equipment for parameter detection, we should verify the verification/calibration results in advance according to the requirements of the testing method and related standards, in order to determine whether the equipment meets the requirements and can not be used for this parameter. Detection, this is an important condition to ensure the accuracy and reliability of the test data.
Whether the measurement equipments that affect the test results configured by the laboratory can be traced back to the national measurement standards, whether the verification/calibration results can meet the requirements of the corresponding standard specifications is an important guarantee condition for the accuracy and reliability of the test result data. CNAS-GL04:2011 "Guidelines for the implementation of traceability requirements" in Article 5.2 specifies that "The reviewer should require the reviewed party to use the calibration certificate/certification certificate/test report data, that is, it can be corrected and judged according to the data. Whether the instrument can be used or not, can it be downgraded, etc.?" That is to say, the verification of the verification (calibration) result should be based on the requirements of the equipment used in the laboratory, that is, to meet the measurement standards for measuring the measurement characteristics of the testing equipment. Claim.
1, make preparations for inspection
1.1 Choosing the Right Measurement Organization The competition in the metrology verification market is very fierce. Some metrology organizations will exaggerate the scope of their qualifications and unfairly pull business. Therefore, when we are selecting suppliers, we must do a good job of evaluating qualified suppliers and verify whether the other party has passed the accredited calibration laboratory or laboratory accreditation. Or calibration qualifications, if the measuring agency does not have the corresponding qualifications, its certificate reviewer is not recognized. The recognition of the validity of the test results of the calibration certificate/certificate certificate/test report is very clearly defined in CNAS-GL04:2011 Guidelines for the Implementation of the Value Traceability Requirements.
1.2 Defining inspection requirements Before the laboratory sends the equipment to a legal, qualified and relevant measurement agency for calibration (calibration), it must be clear that the equipment is used to detect which items in the laboratory. What specific requirements. CNAS-GL04:2011 makes it clear that “reviewed parties should be able to submit their own requirements for calibration/verification/testing to calibration/certification agencies” (CNAS-GL04:20115·3). For example, an oven for the detection of compound fertilizers, GB/T 8573-2010 "Determination of Available Phosphorus Content in Compound Fertilizers" requires temperature (180 ± 2) °C, GB/T 8854-2010 "potassium content of compound fertilizers The determination of potassium tetraphenylborate gravimetric method requires a temperature of (120 ± 5) °C. If the laboratory is equipped with two ovens, then the one used for detecting the effective phosphorus content should be calibrated at this temperature point of 180 °C, and the other The potassium content should be calibrated at 120°C at this temperature point. If it is a common use, 120°C and 180°C temperature points should be calibrated to verify that the equipment meets the standard requirements. Therefore, when filling out the inspection request letter, it is necessary to accurately fill in the verification/calibration requirements according to the purpose of the measurement equipment in its own laboratory and the range of use, so as to ensure that the verification (calibration) data issued by the measurement agency is conducive to the laboratory's anticipation of the requirements. Determine that the verification/calibration certificate really works. Imagine if the oven calibration certificate issued by the calibration temperature point is 100 °C, then how can we determine whether the oven can be applied to the detection of available phosphorus content and/or potassium content? Therefore, the need for verification/calibration of measurement equipment is clearly defined. , It is a precondition to do a good job in verifying the results of equipment metering and to ensure the proper use of equipment.
